"kingspan insulated panels"

Two Kingspan raised access floor systems were used, over a 25,000 sq. m. area, which helped the building achieve LEED Gold. A PSA medium grade RMG system was used in office spaces and PSA heavy grade FDEB_H system was installed in server rooms.

Kingspan Light + Air worked on project jewel at Changi International Airport in Singapore. One of the most innovative project features is the distinctive dome-shaped facade, made entirely of glass and steel. Our team worked with the architects and project team to specify and install over 100 Lumera ventilation windows. The Lumera ventilation windows also operate as an integral element of a wider Smoke and Heat Exhaust Vent (SHEV) system.

Havas Media Group is a global network of entertainment, media and communications agencies, that has recently opened its new ‘HKX’ village in Pancras Square, London to unite twenty-four of its UK operations in a stunning new European headquarters. Given the nature of the fast-moving office environment at Havas, the combination of 14,000m2 raised access floors and 3,000m2 of Attiro magnetic engineered timber (supplied by Fieldmans, one of Kingspan’s supply and install partners) allows for the easy reconfiguration of office layouts and furniture, as well as providing instant access to the underfloor void.

Four years ago, sustainable developer Citu set out to create homes 10 times more energy efficient than typical UK houses. To do this, the company invested in a state-of-the-art production facility where all the components for its properties are built offsite.Thermal performance is critical to energy efficiency. Citu wanted to go far beyond the regulations to achieve wall build-ups with an extremely low U-value of just 0.10W/m2K. This is at least three times better than the U-value achieved in most new build homes and fifteen times better than older houses.Adding offsite capabilityCitu turned to Knauf Insulation for advice and support in developing the offsite capability required for this level of thermal performance. Knauf Insulation’s Technical Support Team undertook extensive calculations and recommended the Blowing Plate Insulation System to install Supafil® Frame – a high performance, non-combustible blowing wool.Supafil® Blowing Wool lends itself to offsite production because it completely fills the cavity, without any voids even around complex penetrations – something that can occur when insulation slabs or rolls are cut to size. It is also a dry process, so operatives are not exposed to any harmful chemicals and it doesn’t require a dedicated production line.Instead, the system comprises a blowing machine and a filling plate. The system is modular allowing for phased investment. Citu opted to install the blowing machine in phase one, which allowed them to manually fill the panels. Phase two saw the addition of the blowing plate, semi-automating the process.Supafil® Frame can be run by a single operator, fits easily into the existing production line, and can even be moved quickly and swiftly to other areas in the manufacturing facility depending on Citu’s volume capacity requirements.Knauf Insulation’s Technical Support Team provided full training and support during each phase of installation.Insulating the panelsCitu homes are manufactured from wooden panels with a 300mm cavity. The blowing plate is positioned over the panel completely covering the cavity. Supafil® is then blown into the wooden frame to the specific parameters of each panel. All cavities are filled to the correct thickness; something that has been carefully calculated and tested by the Knauf Insulation Technical Support Team to ensure settlement does not occur. And because the machine is programmed to install the exact quantity of insulation required, there’s no waste.Supafil® is a high performance Blowing Wool. It is non-combustible with Euroclass A1 reaction to fire classification as well as providing excellent thermal and acoustic performance. It contains a silicone-based additive to ensure it is water repellent.As well as providing excellent thermal performance, Supafil® has great sustainability credentials. Knauf Insulation’s Glass Mineral Wool contains up to 80% of recycled content. This reduces the amount of virgin materials used and prevents around 60,000 tonnes of glass a year (350 million bottles) from going to landfill or polluting the environment. Knauf Insulation has also invested in advanced compression packaging. This means there’s less packaging used, so fewer lorries on the roads leading to a reduction in transport carbon emissions. All of which helps to support Citu’s goal that every home should be carbon zero to manufacture.By combining modern methods of construction with the very highest levels of thermal performance, Citu and Knauf Insulation are creating homes that reduce energy consumption and carbon emissions – homes that are fit for the future.

Factory International will transform the former Granada Studios into a world-class cultural and arts venue in the heart of Manchester. It features The Hall, a large auditorium, and The Warehouse, a flexible multi-purpose space that is taller than four double-decker buses, longer than a jumbo jet and can accommodate 5,000 visitors.Alongside the two public events spaces are The Towers, which house the ground floor entrance foyer, five floors of office space and a plant room at the top of the building. Noise reduces productivity by 66% so when it came to specifying the soffit insulation for The Towers, the architect wanted a solution that would limit airborne sound transfer and reverberation.The insulation would be on display, so aesthetics was also important, and because Factory International will cater for large crowds of people, the chosen solution needed to be non-combustible.Meeting the briefThe architects specified Knauf Insulation’s 50mm Heraklith® Tektalan A2 SmartTec for the soffit insulation in the ground floor foyer of the Warehouse area, main feature staircase, offices and plant room of The Towers.Heraklith® Tektalan A2 SmartTec is a cement-bonded wood wool panel combined with a rock mineral wool insulation core. Both materials have an open structure that naturally absorbs the kinetic energy of sound waves, turning them into heat. It is also non-combustible with an Euroclass A2-s1,d0 reaction to fire classification.Crucially, the Heraklith® wood wool range is also designed for applications where aesthetics is important because the panel is on display. It features bevelled edges and comes in nature tone as standard, or can be ordered in any RAL colour upon request, to create a stylish, uniform finish.To compliment the design schemes in the different zones across the building, contractors, Mansell Building Solutions, ordered the panels in a combination of midnight blue, pebble grey, anthracite and black.Scheduling deliveriesAs the Factory International site is quite compact, there was little room available for storage. So, Knauf Insulation worked closely with distributor Encon Insulation to ensure the insulation was held in stock. Smaller deliveries were then made in line with Mansell Building Solutions’s schedule of works. This ensured that the insulation could be installed as soon as it arrived on site.The product is quick and easy to install. Panels are fixed into position by installing Heraklith® DDS Plus Concrete Screws into each corner and the centre of the panel. The fastener heads have a patented wood wool texture to enhance the finished appearance.Ultimately, installing Heraklith® Tektalan A2 SmartTec onto the soffits in The Towers and the ground floor foyer of the Warehouse not only compliments the design scheme and contributes to fire safety, but it will enable the team behind the events at Factory International to enjoy a quieter working environment too. 

THE PROJECT: Recticel Insulation supplied the high quality insulation solution for an old school in Oxford. The main aim of this project, carried out by Touchstone Lofts, was to convert an uninsulated historic school building originally constructed in 1860 into a modern, energy efficient four-bedroom residential unit. The contractor endeavored to create a two storey dwelling and hoped to minimise headroom loss with insulation in both the floor and pitched roof, therefore selecting the right product was paramount.THE SOLUTION: Eurothane® GP, a low-thermal conductivity PIR insulation panel for use in multiple building envelope applications, was the obvious choice for The Institute’s ground floor and loft insulation. The product's thermal performance of λ = 0.022 W/mK enabled an appropriate thickness selection, so the desired minimum headroom loss was achieved giving the completed build an energy efficiency rating of B. The contractor was thrilled with this given the constraints associated with retrofitting insulation into a period building.Paul Johal, Owner of Touchstone Lofts explained:"Recticel’s insulation provided us with a thermal solution that achieved the required U-value targets whilst keeping the overall thickness to a minimum. The quality of the product is excellent and at a competitive price. The extremely proficient technical team of Recticel Insulation were very responsive with U-value calculations, meaning we could move forward with the project more efficiently. Having the right advice and products from Recticel certainly played a crucial role in achieving our aims. We are delighted with the final outcome."About Eurothane® GP:Eurothane® GP is a high performance PIR insulation board that is light weight, easy to cut, handle and install. Whether it’s a pitched roof, framed wall or floor, Eurothane® GP is the ideal solution amongst contractors and installers

Middlewood Locks is a prestigious 25-acre mixed-use regeneration scheme of Salford’s canal district. The first development phase included the construction of Quarry, an eight-storey building combining ground floor commercial space, luxury apartments and an undercroft car park for residents. It was the insulation for this car park that threw up a challenge for sub-contractor Horbury Building Systems. A complex underdrawing method had been specified, comprising the installation of timber battens, non-combustible mineral wool insulation and a separate soffit insulation over the top. Installation would be extremely labour-intensive, so Horbury Building Systems consulted Knauf Insulation about whether it could provide an alternative that would meet the thermal performance and fire safety requirements, but also be easy to install. Knauf Insulation’s Technical Support Team reviewed the specification and recommended 185mm Rocksilk® Soffit Linerboard Extra to achieve the required 0.18 W/m2K U-value.  Rocksilk® Soffit Linerboard Extra is a Rock Mineral Wool insulation slab bonded to a 6mm off-white weather resistant facing board which provides a two-in-one aesthetic and thermal solution. It has a low thermal conductivity of just 0.034 W/mK and is designed for use as an insulated underlining solution in semi-exposed environments. The off-white cementitious particle board reflects light which makes it ideally suited for use in car parks. As well as thermal performance, Rocksilk® Soffit Linerboard Extra is non-combustible. It has the best possible Euroclass A1 reaction to fire classification, so it will not contribute to the development or spread of a fire should it occur. This is important because car parks can contain large quantities of a potential propellant – petrol. So the insulation will help to ensure the fire safety of the rest of the building.   Rocksilk® Soffit Linerboard Extra also has good sound absorption characteristics so it provides high levels of sound reduction. This reduces noise from the car park, minimising disruption for the people living and working in the premises above. As well as meeting the specification, Rocksilk® Soffit Linerboard Extra has been enhanced to add rigidity and is easy to install. The board is simply placed onto the concrete soffit and fixed into position with five drillscrews. This reduced the installation method from three separate phases to just one, saving Horbury Building Systems time and associated labour costs. Stephen Hampshire, Contracts Manager at Horbury Building Systems said: “We found the panels easy to install. Firstly, we marked and drilled the fixing points at bench level. Next, we held the panels in place to the underside of the concrete – although the panels are lightweight ‘this is a two-handed operation’ – then we drilled through and fixed.”  “We took care in lining the panels together when installing it against the soffit and with some minor tweaking up and down we got a nice flush finish.” Being able to align the panels exactly is not only important for ensuring a good finish. It also means that the slabs will butt tightly together, reducing unintended air gaps which can reduce thermal, fire safety and acoustic performance.  The insulation was supplied to the Middlewood Locks construction site by distributor Galaxy Insulation.  Thanks to Knauf Insulation’s Rocksilk® Soffit Linerboard Extra, the underlining of the car park at Middlewood Locks was easy to install, is aesthetically pleasing, and provides complete thermal, fire safety and acoustic performance.

BACKGROUND: The 74,843-square-foot Student Pavilion is situated at the nexus of student activity on the Tempe campus of Arizona State University (ASU). The building, which was designed to be a Net Zero Energy building, delivers green qualities including renewable energy, energy-efficiency and zero waste to showcase of the university’s goals for Climate Net Neutrality and sustainable building systems. SOLUTION: In order to properly daylight the 21,000-square-foot space on each level and meet design goals, Weddle Gilmore Black Rock Studio utilized the Solatube SolaMaster Series 330 and 750 DS-C units. To ensure a consistent amount of daylight, the design team used Solatube’s proprietary Design Calculator to determine the number of units needed on each level and the amount of light that the Solatube Daylighting Systems would bring into the spaces. Thermal insulation panels were also added to limit the amount of heat transfer into the building from the roof, and extension turrets were used to raise the outer domes and limit the amount of shade cast upon the devices. 

Recticel Insulation’s innovative insulation board - Eurowall +, which has a tongue and groove joints on all four sides to ensure an airtight fit and improved thermal performance, was selected for a desirable new housing scheme built beside one of England’s eminent waterways.The Magenta Court development in Apsley, Hemel Hempstead is a multi-award nominated social housing project on behalf of Dacorum Borough Council. The £6.5m scheme, which stands alongside the famous Grand Union Canal, comprises 29 one-and-two bedroom flats within four blocks. The buildings’ design was inspired by the surrounding wharf architecture present in a nearby listed cottage, papermill and Apsley Lock.Being delivered by main contractor Jarvis Contracting, working with architects RG+P, key to the programme’s success was achieving an energy-efficient building fabric. This led to the specification of Eurowall®+, a high-performance PIR solution from Recticel.This flagship product helps to achieve a 0.18 U-value with a 90mm-thick panel in a 100mm cavity. The lightweight, easy-to-handle board features a tongue-and-groove joint on its four sides, allowing it to be used as full-fill cavity wall insulation with a 10mm clear cavity. The additional space makes for a rapid, more convenient fit for bricklayers when it comes to installation.Simon Blackham, Technical Manager at Recticel explained:This was a tremendous project to be involved with. It’s a superb housing scheme in a great location. With the buildings’ overall thermal efficiency among the priorities, it’s the type of project Eurowall®+ was created for. Further, it enhanced the programme’s sustainable credentials by reducing on-site labour times, thanks to the additional space it affords installers.Eurowall®+ is an exemplar of how high-performance materials can maximise a home’s thermal performance through a fabric-first approach. Its selection for the Magenta Court development was crucial to the creation of a number of desirable, energy-efficient affordable homes, whilst playing a part in ensuring the contractor remained on track to complete the project to the agreed timeframe. About Eurowall®+:Eurowall® + is a premium, high performance full fill insulation board with precision cut tongue and groove joints on all four sides. This ensures that the boards lock tightly together minimising heat loss through thermal bridging. This unique joint offers increased protection against wind driven rain as well as improved windtightness. Eurowall® + is also designed with a 10mm cavity requirement in mind, so that space can be left for conventional bricklaying techniques.

THE PROJECTRecticel’s Eurothane® GP and Eurowall® Cavity provided the quality PIR solution for two city-based social housing developments. Melody Gardens and Corporation Road in Salford, Manchester were built on behalf of Places for People and For Housing. Watson Homes carried out the work on both developments. For Melody Gardens, it involved the building of a four-storey block compromising 48 apartments; nine two-storey houses, and a bungalow. The properties were built on a 0.4-hectare site once occupied by a Catholic church.THE SOLUTIONEurothane® GP, a low-thermal conductivity panel, provided Melody Gardens’ groundfloor insulation. In conjunction with Eurowall® Cavity, it was also installed at Corporation Road which comprises 18 one-bed and 15 two-bed apartments. The products’ durable thermal performance ensured both developments become a valued addition to Salford’s social housing portfolio.Mike Watson, Construction Director at Watson Homes explained:"Recticel’s high-quality products were essential to ensuring the fabric of both developments was fitted with insulation that will fulfil the occupants’ long-term domestic needs. In terms of installation, the panels’ easy-fit properties made quicker and lighter work of a potentially challenging project."Used products:Eurothane GP: Eurothane® GP is a high performance PIR insulation board that is light weight, easy to cut, handle and install.

The Science and Technology Facilities Council’s Rutherford Appleton Laboratory in Oxfordshire is recognised across the globe for its innovative research across a number of scientific fields. The lab employs over 1600 scientists and, as its work has developed, it became clear there was a need for a new, flexible space for testing the latest equipment. Oxford Architects created an iconic, curved design for the R105 Facilities Support Building and, in a break from the standard metal-clad facades of the surrounding buildings, specified a colourful façade using Kingspan Day-Lite Klick wall lights.

Completed in 2016, The Woodsman’s Treehouse is a unique property set high up in the branches of a 200-year-old oak tree in Dorset. The fantastic property is six metres tall and sits 30 feet up in the trees.The Woodsman’s Treehouse needed high performing insulation for the walls in order to keep its guests warm year-round. Due to the already compact area he was building the treehouse in, Guy didn’t want to compromise on space when it came to the thickness of the walls. He needed space saving insulation that still maintained the performance levels of traditional insulation, in order to make sure the heat produced from the wood burner didn’t escape from the building.SuperFOIL provided the project with our SF60 multifoil insulation, which is the world’s highest performing multifoil. The insulation is just 100mm thick, so was the perfect solution to ensure space wasn’t compromised, whilst still offering high thermal performance. The insulation has a 3-in-1 design which consists of three layers- insulation, vapour control and radiant barrier. What this meant was that the treehouse would be protected from condensation whilst still maintaining the right temperature, whatever the season. Offering excellent value for money, SF60 is ideal for both new build or retrofit projects and is certified by BBA and LABC, ensuring it meets the needs of building regulations. The insulation is also made from 40% recycled materials and is fully recyclable at the end of its 50+ year lifespan, so contributed to the sustainability of the project.

Our task was to supply and install 118,254 sq. m. of our PSA MOB PF2 PS/SPU Medium Grade RMG600 for the main areas of the building. By installing over 340,000 panels, our solution accounted for just 6.1% of the building's total carbon.

A 200 sqm, highly energy-efficient new build project in a remote location in the Highlands of Scotland. Built using sustainable materials, and with the timber frame sourced locally and wood fibre insulation used alongside SuperFOIL Insulation throughout. Powered throughout the year using solar PV and battery storage.Looking to increase the thermal resistance of the building envelope in order to reduce energy usage. With the building using an air source heat pump and underfloor heating, they wanted to make sure that any heat loss was minimised and it was vital that they chose the correct insulation for the walls and roof.Solution: SuperFOIL SF19+ is a multifoil product with a total of 11 layers, made of wadding, aluminium coated PET layers and Foil Laminated Outer Layers. At only 40mm thick and providing an R-value of 2.14 when used in a roof, SF19 can be used on its own or in combination with other types of insulation. A fully flexible product that provides a vapour control layer as well as acting as a radiant barrier.

Landmark is a 180,000 sq ft prime office development located in Manchester’s premier business district. Partially built off-site, it has been designed to achieve the highest sustainability standards – a BREEAM rating of ‘excellent’ and an Energy Performance Certificate rating of A so the thermal performance of its insulation was hugely important.Building regulations in England and Wales ban the use of combustible materials on all buildings over 18m. With 14 floors and a roof height of 27m, the architect, Squire and Partners, specified non-combustible insulation with Euroclass A1 reaction to fire classification.With this in mind, external wall sub-contractor FK Group consulted the Knauf Insulation Technical Support Team for advice about which insulation to use. The team conducted 3D U-value calculations and determined that Rocksilk® RainScreen Slab in thicknesses of 50mm, 100mm and 150mm would achieve the desired U-value.Rocksilk® RainScreen SlabRocksilk® RainScreen Slab is manufactured from Rock Mineral Wool and has a thermal conductivity of 0.034W/mK. It is BBA certified for use over 18m and has the best possible Euroclass A1 reaction to fire classification, meaning it met the required specification for fire safety.FK Group also sought advice about what to do if the Rocksilk® RainScreen Slab was exposed to rainwater during installation. There is a common misconception that the thermal performance of Mineral Wool will be permanently compromised if it gets wet, but this simply isn’t the case. Rocksilk® RainScreen Slab has been developed for external applications – its fibre matrix promotes water run-off, and it contains moisture-repellent additives in the binder. This ensures it can withstand higher levels of exposure to moisture during installation. Knauf Insulation also provided advice on the storage of insulation on site to protect the insulation from prolonged exposure to rainwater prior to use.Offsite constructionLandmark was built using an offsite construction method. Decorative concrete rainscreen panels were manufactured by Techrete in Hull. Rocksilk® RainScreen Slab was fitted offsite before the entire panel was transported to Manchester and craned into position on the concrete frame.The Knauf Insulation Specification Team provided further support by carrying out visits to both the Techrete manufacturing facility and the construction site to check the insulation was being installed correctly.SustainabilityAs well as its thermal and fire performance, Rocksilk® RainScreen Slab offers considerable sustainability credentials. It is manufactured with ECOSE® Technology, Knauf Insulation's unique bio-based binder that contains no added formaldehyde or phenol. ECOSE® Technology is made from natural raw materials that are rapidly renewable and is 70% less energy-intensive to manufacture than traditional binder, so it is more environmentally-friendly.Products made with ECOSE® Technology are soft to touch and easy to handle. They generate low levels of dust and VOCs and have been awarded the Eurofins Gold Certificate for Indoor Air Comfort. This is beneficial when insulation is being installed offsite in an enclosed industrial environment.Enhancing the St Peter’s Square heritageMurray Levinson partner at Squire and Partners said “Landmark is an important project for Squire & Partners, representing our first completed new build project in Manchester. When we were approached to design Landmark, we recognised an opportunity to extend the cluster of prime office buildings of the adjacent St Peter’s Square southwards. Our design concept aligned itself with the new developments, whilst creating a building which enhanced its specific site heritage and context.“A priority for both ourselves and the client was to create a building with exceptional sustainability and wellbeing credentials, and we are proud to have achieved BREEAM Excellent and EPC A ratings,” added Levinson.Thanks to its thermal performance, fire safety and environmental credentials, Rocksilk® RainScreen Slab will contribute to Landmark achieving the world's foremost environmental assessment method and rating system for buildings. All of which means this will truly be a landmark building both visually and in terms of sustainability.For further information about how our insulation can contribute to BREEAM, see below.https://www.knaufinsulation.co.uk/all-downloads?search=BREEAM

The unique and stunning curved blue glass cladding specified for the new hospital posed several design challenges. The insulation used needed to provide high thermal performance, be able to conform the curved surface and be completely non-combustible since the building is in excess of 18m. SuperFOIL Insulation was approached to provide replacement insulation that would meet all fire safety standards and which could be applied without requiring changes to the exterior or interior design of the building. After careful consideration as to what would be the most suitable solution, we supplied 5,500m² of our non-combustible SFNC insulation. SuperFOIL SFNC is the only insulation of its kind to be certified by the Building Research Establishment (BRE) as European Class A1 Non-Combustible, which is the highest possible rating of fire safety.

ChallengeThe Building Centre, a central information point for all sectors of the construction industry, recently refurbished its London based headquarters. The second stage has seen Knauf Insulation Acoustic Roll supplied to the Construction Products Association, the UK Green Building Council and Design for Homes offices located on the first floor.In order to maximise all potential space available to the offices, it was essential to select a product that would take up as little space as possible, while satisfying the environmental and acoustic criteria required to achieve the BREEAM ‘excellent’ rating.SolutionTo accomplish this, 50mm Acoustic Roll was specified as it is lightweight, flexible, non-combustible and provides a high level of sound absorption, furthermore, it has been specifically designed for friction fitting between members at 400mm and 600mm centres. Acoustic Roll significantly improves the sound insulation performance of partitions whilst at the same time delivering improved thermal and fire performance. Plus, thanks to ECOSE® Technology, offers outstanding environmental credentials.Knauf Insulation products with ECOSE® Technology are made with a formaldehyde free binder technology derived from rapidly renewable, bio-based materials, which reduces embodied energy and delivers superior environmental sustainability. The insulation doesn’t look or feel like any other insulation. It is naturally brown in colour as there are no artificial colours or dyes added and it produces a ‘super softer’, odourless and easier to handle insulation.Colin Henderson, CEO of the Building Centre comments on how specifying Knauf Insulation was an easy decision to make: "After looking at the requirements and from our existing knowledge of Knauf Insulation, we knew the company would be able to meet all our needs quickly and efficiently."Maria Morgan, Market Manager – Building, Non Residential at Knauf Insulation explains: “Our unique position in having a broad product range, coupled with our expertise within the industry, enabled us to fully advise and install the appropriate insulation solution for the Building Centre.”

At 73m, Thames Quarter is Reading’s second tallest building. It will include 315 built-to-rent apartments, a hub for tech start-ups, a cinema, dining rooms, roof terraces and a residents’ lounge overlooking the Thames.Specialist contractor Precision Façades chose high-performance insulation solutions that would not only contribute to homeowner comfort but would also be kinder to installers. The company specified more than 20,000m2 of Knauf Insulation’s Glass and Rock Mineral Wool insulation for the project.Steve McGowen, Managing Director of Precision Façades explained that Knauf Insulation is the company’s preferred supplier thanks to the high level of support it provides. He said: “Knauf Insulation’s Sales Team are always on hand to help us with our orders, they also have a Technical Team who can provide 3D U-value calculations, and crucially, they are always able to deliver our orders quickly.”The design called for a variety of façade panels manufactured from different materials and finishes, which affected the thermal performance required across the build. To accommodate this, Precision Façades used Knauf Insulation Rocksilk® RainScreen Slab in four different thicknesses (50mm, 100mm, 140mm and 190mm) for the rainscreen façade. It also used 100mm and 150mm OmniFit® Roll 40 within the steel framing system.Both Rocksilk® RainScreen Slab and OmniFit® Roll 40 offer the required levels of thermal performance. They are non-combustible with the best possible Euroclass A1 reaction to fire classification so will not contribute to the development or spread of fire should it occur. This means both products meet the requirements of building regulations in England and Wales banning the use of combustible materials on all buildings over 18m. Rocksilk® RainScreen Slab has also been certified by the British Board of Agrément (BBA) for use in high rise residential applications.Rocksilk® RainScreen Slab and OmniFit® Roll 40 also have excellent sound absorption characteristics ensuring quiet spaces for residents, even while moviegoers enjoy surround sound.In addition to delivering the required thermal performance, both Rocksilk® RainScreen Slab and OmniFit® Roll 40 improve installer’s experience of using Mineral Wool. This is because they are manufactured with ECOSE® Technology, Knauf Insulation's unique bio-based binder that contains no added formaldehyde or phenol.Products made with ECOSE® Technology are soft to touch and easy to handle. They generate low levels of dust and VOCs and have been awarded the Eurofins Gold Certificate for Indoor Air Comfort.As well as being kind to installers, ECOSE® Technology is made from natural raw materials that are rapidly renewable and is 70% less energy-intensive to manufacture than traditional binders.Thanks to Knauf Insulation’s Rocksilk® RainScreen Slab and OmniFit® Roll 40, residents at Thames Quarter will enjoy warm, safe, and comfortable homes, built with insulation that is kinder to installers and the environment.

THE PROJECT: Recticel supplied the low-thermal conductivity insulation boards to ensure new-build homes within a large residential development attained the required levels of thermal performance. The 450-home complex in Salisbury Plain, Wiltshire was fitted with Eurothane® GP boards, which were installed within the properties’ timber-frame cassettes. The insulation was specified for its excellent thermal conductivity of 0.022W/mK. In addition, the boards’ consistent tolerances, straight edges and flatness enhance their usability without compromise to durability. The cassettes containing the insulation were assembled off-site before being installed within the properties’ walls.THE SOLUTION: For this project, the client required a high-performance PIR insulation board that offered walls throughout its collection of houses and bungalows superb thermal performance. This, along with their easy handling ability, made Eurothane® GP boards the ideal solution. It led to the development achieving a U-value of 0.21W/m2K which is above the project’s specific regulatory requirements. It means when the first occupants inhabit this beautifully designed, modern development, they will be inheriting homes that are as comfortable on the inside as they are attractive on the outside.Derek Gough, Senior Estimator at Taylor Lane Timber Frame, which delivered the project’s timber frame properties explained:"Our excellent working relationship with Recticel was key to the success of this project. It’s a collaboration that thrives on their products’ quality, technical expertise and our installation skills and long-held construction experience."About Eurothane® GP:Eurothane® GP is a high performance PIR insulation board that is light weight, easy to cut, handle and install.

ChallengeThe project, at Winston Court in North Walsham, is organised by Benjamin’s Building Company, part of The Benjamin Foundation. Benjamin’s Building Company is a social enterprise that works to create homes, training and employment opportunities for vulnerable people. The ambitious venture will see the development of four, self-contained accommodation units. Seeking help in this task, The Benjamin Foundation turned to CRASH for assistance in locating suppliers and materials.SolutionKnauf Insulation donated 24 rolls of 150mm Loft Roll insulation, 48 rolls of 140mm Rafter Roll 40 and 72 rolls of 110mm FrameTherm® 32 for the project. These glass mineral wool insulation products are extremely easy to handle and install, being lightweight and easily cut to size, benefiting the large project.BenefitsBy its nature, Loft Roll is non- combustible and classified as Euroclass A1 to BS EN ISO 13501-1, a crucial requirement to any public building. Additionally, Loft Roll insulation has been manufactured with ECOSE® Technology which delivers superior environmental performance, as the binder technology is up to 70 per cent less energy intensive than traditional binders. The technology has been developed for Knauf Insulation’s glass and rock mineral wool products, enhancing their environmental credentials without affecting the thermal, acoustic or fire performance. Insulation products made with ECOSE® Technology contain no dye or artificial colours – the colour is completely natural.

When Formby Point Construction needed to specify the insulation for The Gables, an exclusive housing development in Crosby, the project had multiple objectives. Firstly, the company wanted to go beyond the thermal and acoustic requirements outlined in the building regulations. Secondly, with such a large number of applications across multiple construction types, Formby Point Construction wanted to use one manufacturer and supplier to specify the correct product for each application. This would ensure ease of installation and ensure the project was delivered on budget.With this in mind, Formby Point Construction, consulted Formby-based builders’ merchant, Huws Gray, who referred it to Knauf Insulation.For the separating floor applications, Knauf Insulation recommended Knauf Insulation OmniFit® Roll 40, a versatile, non-combustible Euroclass A1 reaction to fire classification Glass Mineral Wool insulation that provides both excellent thermal and acoustic performance. Knauf Insulation also recommended Knauf Insulation DriTherm® Cavity Slab 32 for the masonry cavity external walls, Knauf Insulation Masonry Party Wall Slab for separating walls to comply with Document E and Knauf Insulation Loft Roll 40 for the insulation of the loft.As well as considering the comfort of the homeowner, Formby Point Construction considers the welfare of its employees as part of its decision making. In addition to excellent thermal and acoustic performance, Knauf Insulation scored highly on this aspect thanks to the ECOSE® Technology, its patented sustainable bio-based binder. Products manufactured with ECOSE® Technology contain no added phenol or formaldehyde, and they are 70% less energy-intensive than products manufactured with traditional formaldehyde-based binder. They have no odour, are softer to touch, making them much more pleasant to handle and install. They have also achieved the best possible Eurofins Gold Certificate for Indoor Air Comfort, contributing to a high level of indoor air quality for installers and homeowners alike.Once the specification had been agreed, Knauf Insulation then worked with Huws Gray to price the project and take advantage of volume discounts. This meant that Formby Point Construction had some additional budget for insulation. The company therefore decided to install Knauf Insulation Acoustic Roll within the stud walls between all rooms, going above the minimum standard required between bathrooms and bedrooms outlined in Document E.Thanks to Formby Point Construction’s commitment to going above and beyond the regulations, and Knauf Insulation’s high performance Glass Mineral Wool insulation, homeowners at The Gables will enjoy quieter, warmer homes.

The University of Salford’s new Science, Engineering and Environmental (SEE) building features a white RainScreen façade, punctuated by contrasting red window reveals with a sloping sill to form recessed windows. While this creates an impactful design statement, it proved challenging when it came to evaluating the RainScreen insulation performance.The thermal performance challengeFrom the outset the designers, in conjunction with the University, outlined a desire for non-combustible insulation. But the feature red reveal details meant there were restricted cavity widths near the windows, which would affect the depth of insulation that could be installed. Several Mineral Wool insulation manufacturers had been unwilling to undertake U-value calculations. This was because it was challenging to understand the weighted U-value across the different façade build-ups and determine the U-value uplift required to compensate for the shallower window reveal areas.Architects Sheppard Robson had previously worked with Knauf Insulation and engaged its Project Specification Team to discuss the challenge and develop calculations.After receiving the plans, Knauf Insulation undertook 3D U-value calculations and confirmed that they could meet the required thermal performance – and crucially it would mean no changes to the design or impact on the cavity widths.Accurate 3D U-value calculationsSo how could Knauf Insulation meet the brief when other manufacturers could not?The crucial factor was the type of U-value calculation used. Most manufacturers use the standard method, which calculates the U-value for the build-up without the metal substructure. Because this method doesn’t consider the effect of the metal penetration through the insulation, a blanket correction factor is added, which can lead to the under- or over-specification of insulation. Either way, it means that the insulation used in the finished project may not deliver the thermal performance that has been specified. And in the case of the SEE building, calculating the weighted U-value to prevent this was critical.Knauf Insulation uses numerical modelling (also known as 3D U-value calculations) as standard for all RainScreen façade projects. This methodology thermally models the build-up taking into account the complex interaction between the insulation and the bars and brackets of the steel framing system (SFS). As a result, it creates the most accurate available picture of how the build-up will perform thermally after construction.For the SEE building, the team undertook several different calculations changing elements of the build-up, including the substructure material and insulation widths, until they determined the optimal combination.High performance insulationBy using this rigorous calculation method, Knauf Insulation was able to meet the brief with a combination of 50mm and 160mm Rocksilk® RainScreen Slab, along with 200mm OmniFit® Slab 35.Rocksilk® RainScreen Slab is a Rock Mineral Wool slab that is BBA certified for use at any height and for the broadest range of thicknesses and build-ups on the market. It has a thermal conductivity of 0.034 W/mK.OmniFit® Slab 35, a Glass Mineral Wool slab with a thermal conductivity of 0.035 W/mK, is ideal for use in the SFS.Both Rocksilk® RainScreen Slab and OmniFit® Slab 35 are non-combustible with the best possible Euroclass A1 reaction to fire classification so they will not contribute to the development or spread of fire should it occur. Thanks to their sound absorption characteristics, critical for low mass rainscreen structures, they will help create a quieter environment for the computer and science labs.A sustainable solutionThere was one other specification factor to consider – sustainability. The SEE building had been designed to minimise its environmental impact in line with the University of Salford’s campus master plan.Matthew Taylor, the project architect from Sheppard Robson, noted: “From early on, sustainability has been high on the SEE building agenda, including becoming one of the first all-electric University educational building.” The building will also be supported by photovoltaic panels on the roof.But while the use of renewable energy sources and high performance insulation will help lower the building’s operational carbon, it was important to keep embodied carbon to a minimum.Here Glass Mineral Wool scores highly too because it has the lowest embodied carbon of any mainstream insulation material.Knauf Insulation has proactively reduced the embodied carbon in its products over the years, as part of a broader set of activities to reduce its environmental impact. Specific actions to minimise its carbon footprint include initiatives to reduce road miles in both sourcing and distribution.For example, its Glass Mineral Wool products are manufactured using up to 80% recycled content, including glass collected from the local communities around its factories. The finished products are then compressed by up to 10:1 to fit more product into each lorry reducing transport related carbon emissions.Another innovation is ECOSE® Technology, its unique bio-based binder contains no added formaldehyde or phenol. It is made from natural raw materials that are rapidly renewable and is 70% less energy-intensive to manufacture than traditional binders, so it is more environmentally friendly.Products made with ECOSE® Technology are also soft to touch and easy to handle. They generate low levels of dust and VOCs and have been awarded the Eurofins Gold Certificate for Indoor Air Comfort.Ongoing supportThe through-wall build-up was installed by Metclad Contracts. As this was the first time they had worked with Rocksilk® RainScreen Slab, they also turned to the Specification Team for installation advice. They wanted to know whether the insulation should be fixed into the sheathing boards or the SFS.Knauf Insulation provided details of the fixing pattern together with the installation guide. They also facilitated meetings with their fixing partner to provide specialist technical support about pull out values and requirements for fixing into the substrate.Thanks to Knauf Insulation’s extensive technical expertise and ongoing support, the vision for the University of Salford’s state-of-the-art SEE building has become a reality – without any compromise on thermal performance, fire safety, acoustic or sustainability.

Knauf Insulation is delighted to have been appointed as preferred insulation supplier to innovative new housebuilder, HarperCrewe. In addition to supplying their Supafil® and Loft Roll glass mineral wool solutions, Knauf Insulation will provide support to HarperCrewe’s team, from the design phase through to installation. Their first collaboration is already underway at The Steadings, HarperCrewe’s new neighbourhood of homes in Cirencester, and future projects look set to benefit from the same end-to-end support service. John Nunney, Commercial Director for HarperCrewe explains, “Outstanding build quality is at the forefront of our approach but, as a smaller business, it can be harder to get first pick at the best products on the market. Supafil® 34 is in demand because it’s straightforward to install and it works as it’s supposed to, so our relationship with Knauf Insulation is very important to us. It means we have consistent access to reliable, high-quality products that form an essential part of our builds.” Working closely with HarperCrewe’s design team from the very beginning of the process, Knauf Insulation’s Housing Specification Managers have already helped the business to navigate the latest updates to Part L of the Building Regulations. Advice on SAP calculations and detail drawings, as well as guidance to optimise their insulation specification have helped HarperCrewe’s team meet the new requirements, without compromising on their existing priorities. Of course, getting the specification right is just the first step, so Knauf Insulation’s support will continue well beyond the design phase. As projects move into construction, Housing Specification Managers will attend site start meetings and discuss each plot with HarperCrewe’s team. This will allow them to identify the right time for installation to take place, preventing the product’s performance from being compromised by subsequent construction work. When that time comes, Knauf Insulation’s Regional Technical Managers will be on-hand to offer advice to site teams as needed and ensure a smooth installation.  For projects using Supafil® insulation, HarperCrewe will have access to a list of Approved Supafil® Installers, who have the necessary training and experience to deliver a high-quality installation. Those installers will in turn have access to KinetiK®, Knauf Insulation’s app-based site reporting system that creates an instant digital record of installations.  Using the app on their mobile device, the installer will simply select their site and plot number, take a photo of each elevation, scan the unique QR code on each pack of Supafil®, and install the product as specified. HarperCrewe will then receive confirmation that the specified product has been installed. Not only will this provide additional confidence in the specification integrity, it will also streamline HarperCrewe’s reporting process, giving them more time to focus on the ‘big picture’ aspects of their development. 

CHALLENGEAs part of a full exterior refurbishment, building envelope contractor, Alumet, required a new façade system that would transform and modernise the exterior of the Jubilee House building, which was originally installed in the early 1970s. Coupled with this was the requirement to improve thermal and energy efficiencies.SOLUTIONKnauf Insulation supplied its Rocksilk® RainScreen Slab to ensure optimal fire, thermal and acoustic performance. The key to Knauf Insulation securing the project was the ability to provide in depth technical support, including complex 3D heat flow modelling calculations which took into account the specific system brackets, which act as a significant cold bridge within rainscreen cladding systems.Knauf Insulation’s Rocksilk® RainScreen Slab was installed on the brick facade of the existing building, which once complete, significantly improved the U-value thus reducing the heat loss through the wall.The insulation layer is a fundamental component of any successful rainscreen cladding system and mineral wool insulation delivers a number of advantages for this type of application. Rocksilk® RainScreen Slab is a Rock Mineral Wool slab containing a water repellent additive, designed for use on masonry wall constructions and as the outer insulation layer in steel frame projects.Quick and easy to install, the product is simple to cut and the slabs knit together to create a snug fit, with no need to tape the joints as may be required with rigid foam boards – ensuring maximum acoustic and thermal performance."We wanted to turn our headquarters into a thermally efficient building and to really project a modern ‘green’ image. The Schueco Façade system, along with Knauf Insulation’s products, helped us to achieve this as well as dramatically reducing our carbon output.We have received some fantastic feedback from local residents saying how good the new façade looks and coupled with the improved thermal efficiencies, we are very pleased."- Alumet Director, Dean Walton

Sustainability was a key consideration when British Sugar decided to create a new headquarters to replace its old, tired office.Once the designs were finalised, our floor fitting teams installed RMG600 raised access flooring across the ground floor, first floor and top floor of the building, totalling an area of 4,800m2, utilising our PSA MOB PF2 PS/SPU Medium Grade RMG600 panels.Around the central atrium, we fitted our innovative Attiro architectural finish over the steel-encapsulated RMG600 access flooring system. Attiro is an innovative overlay engineered timber flooring solution that is designed to enable quick and easy access to a raised flooring void at any point in that floor.

Herefordshire Housing Association, announced plans of a five year project with the aim of improving the energy efficiency levels of its entire housing stock, which includes over 500 Cornish type houses across Herefordshire. Many of these homes were built between 1946 and the 1960’s as a ‘temporary’ solution to the post-war housing crisis and they are easily recognised because of their distinctive Mansard roof structure.The contractors, Merriman Roofing and distributor Encon Insulation were given the target of improving the thermal performance of this insulation in the Mansard roofs to a u-value of 0.30 W/m²K, while minimising the disruption to residents which wouldn’t have been possible using traditional means. Because the houses were occupied, all improvement works needed to be carried out from the outside to minimise the impact on the occupants. Unfortunately, due to the Mansard roof which covers the second storey of the building, it’s difficult to significantly improve the energy efficiency of the homes using traditional materials and tools, with a u-value target of 0.30 W/m2.K, traditional insulation was too thick. In the past, efforts to improve the insulation of the Cornish-type homes have been limited by the design of the roof. Achieving a good fit within the timber frame using externally applied options has proved to be challenging due to the narrow cavity between the interior wall and the exterior roof and applying products from inside can typically be disruptive and intrusive for occupants.After visiting the houses that required new insulation, our experts came to the conclusion that our SuperFOIL SF40 multifoil insulation would be the perfect solution to the problem. Because SF40 measures to be just 65mm thick when installed, it was a suitable fit for the unusual Cornish-type properties and their distinctive roofs which only allow a narrow space for insulation. Working with, Herefordshire Housing, Encon and Merriman Roofing Contractors Ltd, we have supplied enough insulation to provide for over 500 houses, improving heat retention in the winter and energy efficiency throughout the year. SuperFOIL worked very closely with Hereford Housing Ltd and Merriman Roofing Contractors Ltd to offer a bespoke solution. SF40 was up to the challenge achieving 0.26 W/m2.K, significantly exceeding their target value. A single layer of SF40 provided maximum performance, minimal thickness, improved air-tightness, radiant barrier, huge cost savings and less disruption to the residents.

A Stoke-on-Trent City Council unit required refurbishment due to its poorly insulated roof and subsequent thermal issues. The 2.000ft2 apex roof and adjoining service areas were refurbished to improve thermal performance with a total of 98, 50mm and 100mm thickness Eurothane® GP boards applied to the building.Spencer Crossley, the store owner explained:"The Eurothane® GP panels have done a fantastic job. They’ve made a huge impact on thermal conditions inside the shop. It means I can keep the store open later. The insulation within the refurbished roof has made for a more enjoyable shopping experience for customers and better working conditions. I’m extremely happy with this fantastic product."About Eurothane® GP:Eurothane® GP is a high performance PIR insulation board that is light weight, easy to cut, handle and install. Whether it’s a pitched roof, framed wall or floor, Eurothane® GP is the ideal solution amongst contractors and installers

Eurowall®+, Recticel’s innovative full-fill cavity wall PIR board, has been chosen for a new affordable housing development. With its advanced tongue and groove joint, it helped to achieve the project’s desired U-value whilst ensuring a ‘built as designed’ envelope.In total, 2000m2 of Eurowall®+ board was installed as part of a £3.3m new-build project in Bedmond Road, Abbots Langley – a large, picturesque village in Hertfordshire. On completion, the 17-home development on behalf of housing association, Thrive Homes, will introduce ‘good quality’ properties to the area. In order that the buildings achieved the regulatory U-value, the insulation needed to ensure a high-quality build whilst being simple to install. Eurowall®+ met both requirements comfortably.  Jarvis Contracting, in conjunction with architects, Avebury, was selected to deliver the scheme. It included the installation of 90mm-thick Eurowall®+ insulation, which earns its billing as Recitcel’s ‘flagship’ product due to its innovative composition and exceptional thermal performance. The boards have a tongue and groove joint on all four edges to ensure they lock tightly together. This inventive format helps to eliminate moisture ingress and possible heat loss through poor joints, whilst offering bricklayers a faster way to build. Once fitted together the boards created a thermally tight envelope, ensuring the fabric-first approach resulted in warm, efficient homes for the Bedmond Road project.  Eurowall®+ can achieve a 0.18 U-value with a 90mm-thick panel in a 100mm cavity. To reach the same thermal performance with mineral wool, for example, the project would require a much thicker insulation. Therefore, Eurowall®+ helps reduce a building’s footprint; a crucial characteristic where plot size is limited.  Indeed, the 10mm air gap, which is created by a 90mm Eurowall®+ PIR board achieving a U-value of 0.18 W/m2K in a traditional 100mm masonry cavity wall, helps speed-up installation times for a more cost-effective build in comparison with other rigid full-fill solutions.Simon Blackham, Technical Manager at Recticel Insulation explained:"Eurowall®+ benefits the installer, due to its slim composition facilitating a more rapid, effective installation, whilst its performance ensures regulation energy requirements are achieved. Such all-round capabilities made it ideal for the Bedmond Road project. It didn’t disappoint on either count."Strong and durable, Eurowall®+ will not degrade or deteriorate due to moisture. This means its thermal performance will be maintained for the long-term comfort and wellbeing of the future occupants of this fine-looking and much-welcome new housing development. About Eurowall®+:Eurowall® + is a premium, high performance full fill insulation board with precision cut tongue and groove joints on all four sides. This ensures that the boards lock tightly together minimising heat loss through thermal bridging. This unique joint offers increased protection against wind driven rain as well as improved windtightness. Eurowall® + is also designed with a 10mm cavity requirement in mind, so that space can be left for conventional bricklaying techniques.

CHALLENGEAn ambitious project, and one of the first certified PassivHaus homes in the UK - the Denby Dale PassivHaus in West Yorkshire, had to to use 90% less energy for space heating than the average UK dwelling – with a space heating need of only 15 kWh/m2/ year. The three-bedroom property is the first UK Passivhaus to be built in a traditional style using cavity wall construction and had to be built to a tight budget of £141,000.SOLUTION“We decided to go down the cavity wall path and arrived at the design for several reasons including: planning restrictions, thermal store, cost, and maybe most important of all, buildability,” explains Bill Butcher, Project Leader.Excellent performing insulation is obviously fundamental to Passivhaus construction and the Denby Dale house has 300mm Knauf Insulation DriTherm® Cavity Slab 32 in the walls, 500mm Knauf Insulation Loft Roll 44 in the roof void (both of which incorporate ECOSE® Technology) along with 225mm of high-performing Polyfoam® Floorboard Standard* insulation in the floor.“We’re fully filling the cavity with glass mineral wool insulation for the walls above ground, because it helps minimise air movement in the cavity and offers greater flexibility, fitting snugly around the ties, openings and imperfections of the masonry surface.” comments Bill Butcher.Economics, performance, availability, ease of fitting and reducing thermal bypass were all among the benefits of the Knauf Insulation products chosen.*No longer sold through Knauf Insulation.BENEFITSGlass Mineral Wool was specified over rigid insulation to ensure a tight thermal fit. Knauf Insulation DriTherm® Cavity Slabs are flexible enough to eliminate air gaps and prevent heat loss due to their inherent ability to knit together at joints between the slabs. If rigid insulation is used and fitted badly with too many gaps, air movement around and between the insulation boards is increased, which can drastically reduce its insulation value.Knauf Insulation DriTherm® Cavity Slabs are BBA Certified for all exposure zones and formally guaranteed for 50 years to prevent the transmission of liquid water from the outer masonry leaf to the inner masonry leaf.In addition to its thermal performance glass mineral wool also has other sustainable features. In manufacture it uses a high content of recycled glass bottles and requires less overall energy consumption than some alternative products, resulting in less carbon emissions. In addition, it can be recycled at the end of a building’s life and has zero GWP and zero ODP. ECOSE® Technology further extends these established green credentials as it is manufactured with 70% less energy than traditional binders and the products contain no dyes or added formaldehyde – providing the ideal solution to the eco-friendly house.

The PROMAT ULTIMA® VIP range of ultra-thin vacuum insulated panels from Promat UK utilise next generation materials technology to deliver the highest levels of thermal insulation, without the bulkiness associated with traditional insulating products. With standard thicknesses of between just 10mm and 50mm, PROMAT ULTIMA® VIP panels are ideal for applications where space constraints pose a challenge to delivering on thermal goals. It is an effective insulation for a wide range of applications including structures, flat roofs and facades with the benefit of being manufactured by Promat in ISO 9001: 2015 and ISO 14001:2015 factories for consistent quality assurance and traceability.

When MCR Property Group purchased Unity Square in Liverpool, a £17m partially built student living scheme, it wanted to complete the project as quickly as possible.The specification required a non-combustible insulation solution that complied with building regulations for the acoustic insulation of internal walls and separating floors. The company needed a large quantity of insulation delivered within a very short lead time to coincide with the period when hired vehicles would be on site. With this in mind, Knauf Insulation suggested Rocksilk® Flexible Slab, its multi-purpose Rock Mineral Wool insulation.Designed for use in a wide variety of applications including internal walls, floors and partitions, and separating floors, and with excellent thermal performance, Rocksilk® Flexible Slab exceeded the specification requirements. Furthermore, Rocksilk® Flexible Slab has a non-combustible Euroclass A1 reaction to fire classification, making it suitable for internal use on residential dwelling buildings over 18m tall as outlined in the recent changes to Approved Document B.As well as thermal and fire performance, Rocksilk® Flexible Slab has excellent sound absorption properties, providing high levels of sound insulation. As a result, the installation of the product in the 204 bedrooms and 36 studio flats will make life much more comfortable for the students living on the campus.Rocksilk® Flexible Slab is manufactured with ECOSE® Technology, Knauf Insulation’s unique bio-based binder that contains no added formaldehyde or phenol. Products made with ECOSE® Technology generate low levels of dust and VOCs (volatile organic compounds) and have been awarded Eurofins Indoor Air Comfort (Gold) certification.Builders’ merchant, Selco Ardwick in Manchester, supplied Rocksilk® Flexible Slab direct to site. In total, 32 pallets were used, equating to nearly 3,500m2 of insulation.For ease of installation, Rocksilk® Flexible Slab features a flexible edge which is designed to optimise friction fitting between studs, joists and rafters. MCR Property Group team found that its flexible edge combined with its lightweight design made the product much easier to install than alternative Rock Mineral Wool insulation they had used previously.Thanks to Knauf Insulation’s speed of delivery, MCR Property Group was able to keep to a tight schedule that saw Unity Square open its doors in September in time for the start of the academic year. And while most of the students probably won’t give a second thought to the insulation, they will enjoy their safer, warmer and quieter new homes!

Entering a building is usually the only way to find out what takes place inside. But that’s not the case with the Manchester Metropolitan University’s new School of Digital Arts (SODA). It acts as a giant canvas to illuminate digital content produced by students, thanks to an LED rainscreen façade on its northern face. The five-storey, 5,200m2 SODA building is adjacent to the Manchester School of Art and will provide space for a digital innovation and User Experience (UX) lab, film studios, green screens, edit suites, sound, music and production studios; alongside a screening room and gallery space. Like all rainscreen façade projects, the SODA building needed insulation to meet the required thermal, fire safety and acoustic performance, but the LED façade added complexity to the specification. The chosen rainscreen panels were perforated with small holes to allow the lights to shine through – but this also meant the insulation could be seen from certain angles, so the insulation needed to look aesthetically pleasing too. During the design process, architects Feilden Clegg Bradley Studios had specified Knauf Insulation’s Rocksilk® RainScreen Slab for the project. It is non-combustible with a Euroclass A1 reaction to fire classification, so complies with building regulations that ban combustible insulation on certain buildings over 18m tall in England and Wales.  Rocksilk® RainScreen Slab also has a thermal conductivity of 0.034 W/mK so could meet the U-value of 0.19 Wm2K. And thanks to its sound absorption characteristics, critical for low mass rainscreen structures, it will help create a quieter space for the students. The principal contractor Kier Construction had tasked specialist façade contractors Maple Sunscreening with determining the required thickness and aesthetics. So they contacted Knauf Insulation to discuss the best solution.  Knauf Insulation’s Technical Support Team undertook 3D U-value calculations and confirmed that a 150mm slab should be used for the project.  What’s more, Rocksilk® RainScreen Slab is manufactured with ECOSE® Technology, Knauf Insulation's unique bio-based binder that contains no added formaldehyde or phenol. This gives Knauf Insulation’s mineral wool its unique brown colour, so the insulation won’t stand out behind the perforated rainscreen panels. It also makes it soft to touch, easy to handle and generates low levels of dust and VOCs. As a result, products made with ECOSE® Technology have been awarded the Eurofins Gold Certificate for Indoor Air Comfort. Rocksilk® RainScreen Slab is designed to be easy to install correctly. Slabs are robust which makes them easy to manoeuvre into place. Once in position, they butt tightly together and adapt to any imperfections in the substrate. This prevents unintended air gaps that can compromise thermal, fire safety or acoustic performance. Using Rocksilk® RainScreen Slab was the optimal solution for the SODA building providing both the high thermal, fire safety and acoustic performance demanded of modern buildings. And thanks to its unique brown colour, the mineral wool insulation won’t be a distraction, instead acting as the perfect backdrop for the dazzling LED light displays created by the students. 

Today’s students demand a high standard of living, and with 348 beds, separate study and social spaces, a dining room and gym, The Malthouse, new luxury apartments in Wilder Street, Bristol have been designed to provide it.Spread over five stories, the external envelope features a combination of different coloured brickwork and rainscreen cladding. AWW Architects had specified non-combustible insulation to meet the requirements of building regulations in England and Wales, which ban the use of combustible materials on the external walls of certain types of buildings over 18m.With this in mind, main contractors Watkin Jones contacted Knauf Insulation’s Technical Support Team to determine which insulation solution would be most suitable to achieve the required U-value of 0.19 W/m²K. They also wanted to determine whether the wall build-up would prevent cold bridging and act as a vapour barrier.The Technical Support Team undertook complex 3D U-value calculations and condensation analysis. 3D U-value calculations completed in line with BS EN 10211 are used for rainscreen projects because they are the most accurate way to ensure a building’s thermal performance matches the initial design. The Technical Support Team provided a fast turnaround on the enquiry and recommended 100mm Rocksilk® RainScreen Slab as the best solution for the project.Manufactured from Rock Mineral Wool, Rocksilk® RainScreen Slab is non-combustible with the best possible Euroclass A1 reaction to fire classification. This means it will not contribute to the development or spread of fire should it occur. As well as having a British Board of Agrément (BBA) certificate for high rise residential applications, it also has a BBA certificate for use behind masonry façades – making it suitable for the different applications on The Malthouse.In addition to fire safety and thermal performance, Rocksilk® RainScreen Slab offers excellent sound reduction characteristics.More than 8,000m2 of Rocksilk® RainScreen Slab insulation was supplied to the development by builders’ merchants M Markovitz Ltd.Like all Knauf Insulation products, Rocksilk® RainScreen Slab has been designed for ease of installation. Improved robustness means it is easy to manoeuvre into place and it can be installed either way round without compromising performance.Rocksilk® RainScreen Slab is manufactured with ECOSE® Technology, Knauf Insulation's unique bio-based binder that contains no added formaldehyde or phenol. Products made with ECOSE® Technology are soft to touch and easy to handle. They generate low levels of dust and VOCs and have been awarded the Eurofins Gold Certificate for Indoor Air Comfort. ECOSE® Technology is also made from natural raw materials that are rapidly renewable and is 70% less energy-intensive to manufacture than traditional binders, so it is more environmentally friendly.Thanks to the technical support from Knauf Insulation, The Malthouse will deliver the students a comfortable, warm, quiet and safe environment where they can enjoy their university years.

The Vaughan Way development in Leicester features state-of-the-art apartments above a two storey car park. While this gives residents the best of both worlds – city living and parking in a limited footprint – it represents a challenge for developers in the form of thermal bridging.Most car parks feature open walls to allow adequate ventilation of exhaust fumes, so the separating floor must be well insulated to prevent warm air from the flats escaping into the car park below. With this in mind, main contractor Winvic approached Knauf Insulation for advice on the best insulation to specify in order to achieve the specified U-value of 0.2 W/m²K.Knauf Insulation’s Technical Support Team conducted U-value calculations to determine the thickness of Soffit Linerboard required. They then worked closely with Winvic to provide technical advice to ensure all design considerations were addressed.Soffit Linerboard is a robust Rock Mineral Wool slab. It is a high-performance thermal insulation and offers excellent sound absorption to provide high levels of sound reduction; something residents will appreciate when their neighbours are parking below.Soffit Linerboard is also non-combustible, with an A1 Euroclass Reaction to Fire Classification, essential to comply with changes to the building regulations, as Vaughan Way will be more than 18m tall when complete.Soffit Linerboard is one of more than 40 Rock Mineral Wool insulation products produced at Knauf Insulation’s Queensferry plant. It is manufactured with ECOSE® Technology, Knauf Insulation’s unique bio-based binder that contains no added formaldehyde or phenol. It is made from natural raw materials that are rapidly renewable, and is less energy-intensive to manufacture than traditional binder, so it is more environmentally-friendly.Products made with ECOSE® Technology are soft to touch and easy to handle. They generate low levels of dust and VOCs, and have been awarded the Eurofins Gold Certificate for Indoor Air Comfort.The insulation was delivered direct to site by distributors Encon in Nottingham and was installed by sub-contractors L Reynolds.From the additional warmth, to noise reduction and improved safety, adding Soffit Linerboard to the separating floor between the car park and flats will make city living even more pleasant for the residents of Vaughan Way.

ChallengeThe much acclaimed architect Zaha Hadid created the design for the Riverside Museum, which has already been dubbed ‘Glasgow’s Guggenheim’.The new riverside Museum provides an exciting new home for Glasgow’s transport collection. The development has a riverside location on a site where the River Clyde meets Glasgow’s other main river the Kelvin, and is adjacent to Glasgow Harbour.The dynamic new Riverside Museum displays Glasgow’s rich industrial heritage, which stems from the River Clyde. The Tall Ship is berthed alongside the Museum, creating a fantastic experience in this stunning setting.The brief for design and build roofing specialist Varla (UK) Limited was to find a flexible insulation that could meet the demanding U - value of 0.20 W/m2K that was continuous over both the walls and the complex 18,000 square metre roof. The Glasgow Museum of Transport is a complex, heavily engineered design and was the first major UK project for the renowned architect Zaha Hadid.Specialist Roofing contractor, Varla (UK) Limited started the search for a suitable material by contacting many insulation suppliers and holding supplier seminars at Varla’s Chester offices, challenging suppliers to propose a solution to meet the demanding specification for this unique project.SolutionVarla (UK) Limited chose to use Knauf Insulation’s FactoryClad Roll 32, a flexible insulation that meets the demanding U-value of 0.20 W/m2K across both the roof and walls.Rigid foam boards were ruled out early on, as they could not be fitted to the building’s complex curves. There was also a limited cladding zone that could not be altered. Many types of insulation were considered, but glass mineral wool roll provided the best thermal efficiency. The key to Knauf Insulation’s products being specified on this project was its ability to provide in-depth technical support, including complex three-dimensional heat flow modelling calculations. This allowed Knauf Insulation to produce a solution that met all of Varla’s insulation requirements by using a double layer of 100mm Knauf Insulation FactoryClad Roll 32. This is a flexible, lightweight roll of resilient Glass Mineral Wool with exceptionally high tear strength and a thermal conductivity of just 0.032 W/mK.In addition, Knauf Insulation FactoryClad Roll 32 is ideal for limiting the spread of fire since it holds a Euroclass A1 reaction to fire classification for non-combustibility and will not burn. Nor will it give off toxic smoke or suddenly ignite in a fire due to ‘flashover’. For public buildings such as this, superior fire performance is crucial.Once Varla (UK) Limited had decided on Knauf Insulation, it leaned on them heavily for technical support, utilising the unique 3D heat loss calculation support service, which ensured the correct product thickness was specified to meet the demanding project requirements.
