At Polyroof, we take pride in providing innovative liquid roofing solutions that meet the unique needs of our clients. From project conception to completion, our expertise lies in creating high-performance roofing systems that offer both durability and aesthetic appeal.This case study highlights our collaboration with Woodholm, a picturesque property located in Southerness, constrained by the Dumfries & Galloway Council Planning’s “room in the roof” design.The SolutionWoodholm’s owners were determined to create a home that would evolve organically while adhering to the council’s planning regulations. To achieve their vision, they enlisted the services of David Lamb Architectural Services to submit a Planning Application on their behalf, seeking approval for a modification from an existing apex roof design to a curved roof. After going through the rigorous process, the application successfully obtained full Planning Committee approval on 14 February 2017.To realise their desired construction, Woodholm’s owners had a preference for using wood and oak, aiming to incorporate these elements into the design. To accomplish this, they collaborated with Carpenter Oak Woodland, a renowned timber construction company known for their expertise in oak framed structures. The company skillfully designed an oak framed structure that perfectly met the owners’ requirements. By mid-November 2017, Woodholm had a stunning and aesthetically pleasing frame in place.However, finding an ideal roofing solution proved to be a challenging task for Woodholm. Initially considering a zinc roof, they encountered obstacles due to the prohibitive costs and the challenges posed by their maritime environment, as Woodholm is located directly on the shores of the Solway Firth. It was at this point that David Lamb’s initial positive impression of a roofing product caught their attention. Woodholm’s owners approached Polyroof’s simulated metal finishes with their needs and were introduced to the Polyroof technical team. The team guided them through the necessary technical specifications to meet the Scottish Building Warrant for a Warm Roof, ensuring compliance with the required standards.Fortuitously, Woodholm’s owners discovered that Polyroof would be exhibiting at the “Homebuilding & Renovating Show” from 21-22 October 2017. At the event, they had the opportunity to meet the Polyroof team as well as Contractor, Kenny Scott of LK Roofing, Lochmaben. The Woodholm team was highly impressed and reassured by the collective experience, knowledge, and technical expertise demonstrated by Polyroof and LK Roofing. Equally important, they appreciated their ability to attentively listen to and understand their concerns.Following the show, a site meeting was promptly arranged with LK Roofing, allowing all parties to discuss the project in detail. As a result, a comprehensive and competitive quotation was provided, falling comfortably within Woodholm’s budgetary requirements.By early December 2017, Woodholm’s joiner had installed the sub-decking, which served as the foundation for the roofing system. LK Roofing then expertly applied the Alutrix membrane, a high-quality waterproofing layer, providing Woodholm with a watertight working cover.Thanks to our collaborative efforts with Woodholm, the project achieved a seamless integration of their desired curved roof design, wood and oak elements, and our advanced liquid roofing system. Woodholm’s owners were delighted with the final result—a beautiful, organically evolving home that not only met their needs but also exceeded their expectations.At Polyroof, we are dedicated to providing roofing solutions that offer both outstanding performance and stunning aesthetics. The Woodholm case study is a testament to our commitment to delivering innovative products and excellent customer service, tailored to meet the unique requirements of each project.

Easy to handle, even for this incredibly large project.The Costco store in Wembley occupies a site close to the national football stadium. For the building’s flat roof, architects, Broadway Malyan, in conjunction with main contractors, JF Finnegan, required insulation comprising superb thermal performance and easy-handling ability - Recticel’s Eurothane Eurodeck more than fitted the bill.Ian Catterall from BC Contractors explained:"Eurothane® Eurodeck is a superb quality board. It’s really easy to install and presented no issues for what was an incredibly large project - the largest single-value project we have undertaken. It was an immense job, which required the highest-quality PIR.

Cowley Road in Brixton is situated in a vibrant area of London where main contractors, Pinnacle Building Solutions were faced with the task of refurbishing an existing apartment block to a standard that reflected the higher standards of living now demanded in the area.Pinnacle Building Solutions were tasked with reducing not just airborne noise, but impact noise too. This is a classic problem in buildings constructed when building regulations were considerably more lax than today. This problem is compounded by modern tastes having moved away from carpets throughout the living space. Finally, the tight urban site demanded that all trades work together to an equally tight schedule of works.Soundis supplied over 2,850m2 of Acoustic Matting and Underlays. The end result being an installation that surpassed the building regulations Part E for both airborne and impact noise with ease.

The former Royal Military Academy overlooking Woolwich Common finds a new place in history with its stunning restoration, featuring Kingspan OPTIM-R Flooring System. The vacuum insulation panel system was chosen to most of the available space. The original beam and block flooring limited the ability to dig down, so installing the Kingspan OPTIM-R Flooring System in a 30mm thickness allowed for the maintenance of the existing threshold levels whilst also achieving excellent thermal performance.

Sonixx Resilient 250 was installed as an acoustic underlayment. It was bonded to the subfloor and a heterogenous vinyl and carpet tiles were installed on top.

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 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.

Comprising of nine shops and several residential flats, properties 29-47 High Street Polegate required a full roof refurbishment after complaints of water ingress into the residential buildings. Proteus Waterproofing conducted a thorough survey which revealed that the existing roof build up, made up of a timber deck and 2-layer felt, had been previously repaired but was now at the end of its serviceable life.Being a residential building with a combustible deck, protecting individual properties from internal fire spread was a key consideration. Compartment walls were identified allowing Proteus Waterproofing to provide a solution that would meet regulatory guidance relating to the junction of compartment walls and roofs in Approved Document B whilst meeting the needs of the client.Proteus Waterproofing specified their robust reinforced bitumen membrane range of Proteus Pro-Felt®, including a bespoke hybrid insulation approach, where instead of a full replacement consisting of entirely non-combustible insulation, a scheme was designed to meet the requirements above and either side of the compartment walls, offering the client the most cost-effective solution possible that would also mitigate any unnecessary increase of weight loading elsewhere on the roof.High Performance WaterproofingThe waterproofing and existing deck were stripped back and re- decked with 18mm plywood. When removing the existing waterproofing, our approved contractor, carefully recorded the exact location of the party walls as no drawings of the upper story flats were available.Proteus Pro-Felt® SA AVCL was used as a vapour control layer to allow for the application of the hybrid combination of 150mm Proteus Pro-Therm PIR insulation and 150mm Proteus Pro-Therm Mineral Wool insulation. A thermal calculation was undertaken to ensure that the final result met the requirements of Part L of the National Building Regulations. These were both adhered with Proteus Pro-Bond Foaming Adhesive. Proteus Pro-Felt® SA Underlay Plain was laid and finished with Proteus Pro-Felt® Ultima Plus Fireguard Mineral Capsheet, providing the client with a fully waterproofed Part B and Part L compliant roof, guaranteed for 20 years.Proteus Waterproofing worked closely with the Proteus Approved Contractor, to ensure the project was delivered to a high standard.Health & SafetyWhen working on occupied buildings, safety is always of utmost importance, as well as keeping disruptions to a minimum.

Our tapered roofing insulation was installed on London's first cable car system spanning the River Thames

A 1963 Vanwide railway goods wagon with plans to turn it into a garden room for a family. To get the wagon to a usable state, a full strip out was required, leaving only the metal casing of the original wagon remaining. Once the wagon was stripped back, there wasn’t much metal remaining for the roof, only six thin metal trusses were left. Due to the shape of the wagon, insulation was needed that not only performed well but was fully flexible to fit the arched roof. It was also important that the insulation had a shallow profile to fit into the narrow space. Looking to insulate the 2m x 5m roof, careful consideration had to be given to retaining the original look of the carriage.

ChallengeKalzip were tasked, alongside contractors Lakesmere, to develop a roofing structure that would be vital to the overall appearance of the building and one that would fulfil the stringent acoustic criteria – whilst working to tight deadlines.SolutionFollowing extensive testing, Knauf Insulation Rocksilk® RS45 product in 50mm and 75mm were specified within the 40,000m2 Kalzip System in the AluPlusPatina finish.Heathrow’s new Terminal 2, also known as The Queen’s Terminal, boasts exceptional architectural design and is 40% more carbon efficient than the previous building. Kalzip’s large waveform roof bestows one of the iconic features of the terminal.A multi-layer approach was taken when it came to installing Knauf Insulation Rocksilk® RS45. By layering the insulation products in different densities across the Kalzip standing seam roof, rigorous sound absorption and sound transmission measures were met, whilst retaining the form and functionality required by the designers.As a robust, resilient and dense Rock Mineral Wool insulation slab, Knauf Insulation Rocksilk® RS45 has excellent acoustic properties that help to reduce the impact of airborne and rain impact noise. It also has an excellent thermal conductivity of 0.035W/mK, helping to provide passengers with a comfortable environment.

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.

CMS Danskin were able to provide Regupol 4515 (REGUPOL sonus eco) to the prestigious new Gateway project in central Leeds. As the city centre’s largest residential project to date, it has also provided the area with a luxury landmark.In keeping with high-end living, the interior design of the new build project incorporated a number of characteristic atrium and foyer spaces. While this lack of uniformity gave the building and its apartments an impressive level of individuality, it also created irregular shaped rooms which were difficult to work with from a finishing perspective.The finish of the apartments incorporated tiles throughout all of the bathroom and shower areas. To comply with Part E impact sound regulations, an acoustic flooring system had been specified for use under the tiled floor finish. However, when the tile fitters began installation, a number of challenges emerged.Phil Johnson, building development manager at Aqua Interiors, explains:“The acoustic matting and adhesive combination we were initially using at The Gateway caused us a few problems. There were issues from the tile fitters regarding application of the adhesives, and the over flexibility of the system meant that the grouting was cracking and crumbling once the surface was subjected to weight and traffic.” As the tiling contractors were already on-site, a reliable alternative that would meet Part E standards for impact sound had to be sourced and delivered against extremely tight timescales.The SolutionAs the only acoustic tiling system on the market to comply with the UK Tiling Association’s (TTA)Coefficient of Restitution figure (0.56), a test method to assess the impact resistance of ceramic floor tiling, Regupol Acousti-Tile was identified as the best solution to overcome the difficulties being experienced at The Gateway.The main component in the Regupol Acousti-Tile system is Regupol 4515 Multi (REGUPOL sonus eco), a high performance acoustic underlay which isolates impact sound at source. Regupol 4515 Multi (REGUPOL sonus eco), which can be used with any finish, is first bonded to the construction’s base floor using Ardex AF200.Tiles are then laid on top of Regupol 4515 Multi (REGUPOL sonus eco) using BAL Acousti-Bond adhesive. The acoustic tiling system is completed by filling in the joints using an appropriate grout finish, which is dependent upon whether the base floor is concrete or timber.As a complete acoustic tiling system, all components of Regupol Acousti-Tile are delivered to site in a single delivery. Regupol 4515 Multi (REGUPOL sonus eco) and the complete Regupol range is available exclusively in the UK through CMS Acoustics.The ResultThe quality of the finished bathroom environments is in keeping with the ambition and attention to detail of The Gateway project overall. By installing RegupolAcousti-Tile, Aqua Interiors has ensured that the impressive tiled floor surfaces will not cause residents disruption because of excessive noise transfer between dwellings.Having undergone independent site trials, Regupol Acousti-Tile has been shown to achieve an impact sound value of up to 52dB, which is significantly less than the 62dB required by Part E of the Building Regulations.Johnson concludes: “All of the environments were around 4-5m², but there was a great deal of variation in the room shapes and sizes, meaning there were some changes to the setting once we were on-site.Regupol Acousti-Tile was versatile enough to cope with any changes we made – the Regupol 4515 Multi (REGUPOL sonus eco) element was easy to trim and shape while BAL Acousti-Bond offered the same.

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.

The new £8.5m Allam Diabetes Centre at Hull Royal Infirmary plans to treat and care for patients with diabetes and metabolic bone diseases.It also includes a significant amount of clinical research facilities supporting not only diabetes and endocrinology, but also vascular surgery, neurology and other research departments. Its curved towers flank a glass entrance, which leads to a large waiting area and reception. Spread over three storeys are consulting rooms, specialist treatment rooms, office space and changing rooms as well as a roof terrace on the second floor. Designed to achieve a BREEAM rating of ‘very good’, the thermal performance of the insulation specified for the Allam Diabetes Centre’s flat roof was hugely important. Another crucial factor was fire safety. Although the application doesn’t fall under current fire regulations banning combustible insulation, the architect specified that only non-combustible materials should be used during construction.  Main contractors Zenith Developments appointed specialist contractors Fosters Roofing to install the roof. They in turn tasked DANOSA UK with supplying all the materials for the roof construction, including the insulation. “The build-up of the Allam Diabetes Centre was a single-ply warm roof with a tapered insulation scheme to provide the fall required for rainwater run-off,” explained Steve Downey, Commercial Director at DANOSA UK. “Tapered insulation schemes are always more difficult than traditional flat roofs, so we asked Knauf Insulation for technical advice on how to achieve the required U-value of 0.18 W/m2K.” The Knauf Insulation Technical Support Team recommended Rocksilk® Flat Roof Slab. It is BBA certified for use on mechanically fixed flat roof build-ups and is suitable for all types of roof deck.  As well as excellent thermal performance, Rocksilk® Flat Roof Slab is non-combustible with the best possible Euroclass A1 reaction to fire classification. It also provides excellent sound absorption so will help reduce the drumming effect of rainfall.  Rocksilk® Flat Roof Slab contains a special water repellent additive and is manufactured using Knauf Insulation's Krimpact® Technology which provides high levels of compressive strength and durability. As the project was a tapered insulation scheme, Rocksilk® Flat Roof Slab was manufactured to order to ensure the correct fall was created. The tapered insulation scheme wasn’t the only challenge with the Allam Diabetes Centre – it also features a curved façade, which added complexity for the installation team at Fosters Roofing.  Paul Foster, Managing Director at Fosters Roofing said: “Insulation needs to be carefully cut to the exact shape of the building otherwise heat can escape making it less energy efficient. Thankfully Rocksilk® Flat Roof Slab was easy to cut and quick to install, so it wasn’t a problem.” Rocksilk® Flat Roof Slab has also been designed to knit together during installation so there are no gaps that could affect thermal, fire or acoustic performance. By using Rocksilk® Flat Roof Slab, Fosters Roofing and DANOSA UK were able to achieve the required specification for the tapered insulation scheme on the new Allam Diabetes Centre. This will contribute to the energy efficiency needed to achieve the BREEAM ‘very good’ rating. 

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.

The increased levels of thermal insulation found within the roof voids of a modern house is intended to reduce the amount of heat that is lost from the warm living spaces of the property over time. However breaks in this insulation layer, such as through the loft access door, will severely compromise its effectiveness. This editorial explains how to avoid losing heat in the loft space and therefore losing money.

ChallengeWork is underway to create a new theatre that will transform the existing 1932 Royal Shakespeare Theatre whilst retaining the original Art Deco and Victorian elements of the building. Due for completion during 2010, the theatre will give artists and audiences alike the best environment in which to perform and enjoy Shakespeare with improved public spaces both inside and surrounding the theatre.The challenge for the project design is to blend the key aspects of the existing buildings with the new theatre designs. Specialist roofing contractor, Varla (UK) Limited were awarded the contract to design, manufacture and install the zinc standing seam roof and wall package. Varla (UK) Limited challenged Knauf Insulation to propose a solution to meet the demanding specification for this unique project.SolutionKnauf Insulation provided detailed ongoing technical support during the design stages of the project and proposed solutions based on the results of unique three-dimensional heat loss calculations. The unique 3-D calculation support service, provided by the Technical Advisory Centre, was an integral part of the product specification process to ensure that the exact thickness recommendations were proposed in order to meet the project’s specific U-value requirements.Knauf Insulation were able to provide a solution that met all of Varla’s insulation requirements by using 160mm of 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, recommended for this project, is manufactured from Glass Mineral Wool, which is ideal for limiting the spread of fire since it holds a Euroclass A1 reaction to fire classification for non-combustibility. The product will not burn, will not give off toxic smoke nor will it suddenly ignite in a fire due to ‘flashover’. For public buildings such as this, superior fire performance is crucial.

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

ASE STUDY PROJECT NAME: DERBYSHIRE HOUSE RENOVATION PRODUCT SUPPLIED AEROMIX SUPPLIED AND INSTALLED BY: CLOCKWORK SCREED INITIAL BRIEF: Garage to a one bed bungalow conversion. Aeromix was chosen for this project thanks to its many benefits of offering warmth, smoothness of finish and speed of install. The floor needed to be strong and warm so by using Aeromix with its thermal properties the finish was amazing. 175mm Aeromix was poured directly over compacted hard core topped with 65mm C20 liquid screed . The builder who completed this project AA BUILDERS DERBY said “The product is amazing and the finish is amazing, I would recommend it to anybody and everybody” Building control, GEORGE REDGRAVE DBCP He was very impressed with the flooring and commented “what a nice finish. , this is the way forward” Aeromix provided the ideal solution for the insulation on this project, compared to the normal concrete floor and other traditional methods, the speed of pumping the insulation coupled with the high thermal properties has contributed in saving the customer both time and money. 

ChallengeContractors Guaranteed Asphalt (GA) faced a unique conundrum regarding the insulation of the roof of the O2 Arena, the centre piece on the site of the former Millennium Dome and the first purpose-built music venue in London since The Royal Albert Hall in 1871.As the area required superior acoustic properties, a rock mineral wool product was the obvious solution, however the split-level roof form of the construction meant that loose mineral wool fibres were visible in the surrounding airspace. This is where Knauf Insulation’s technical expertise became invaluable! Knauf Insulation was able to specify a bespoke white-tissue-faced Krimpact product which entrapped the loose fibres.SolutionKnauf Insulation supplied over 100 tonnes of their Rocksilk® Flat Roof Slab Extra at 150mm (2x75mm), a consistent, high density rock slab with superior impact and compression resistance. This material is designed to offer not only the acoustic performance required by such a venue, but also good thermal resistance and an excellent fire rating classification (Euroclass A1 non-combustible, the highest level possible). The white-tissue-faced product was suitable to be exposed to the elements, and later sprayed with a grey solar reflective paint to seal the surface and enable the product to camouflage into its environment.To make the project even more complicated, the cranes used in the production did not fit under the existing structure of the Dome which meant that the roof had to be constructed at ground level and lifted into its final position. This was no problem for Knauf Insulation thanks to its innovative Supakube delivery system, which meant the product could be delivered to the correct area of the project with minimum effort. Supakube uses advanced compression technology and strong packaging materials, which ensures the product is not only easy to store but can be delivered more efficiently saving time and reducing carbon emissions from delivery vehicles as more product can be loaded onto each lorry.

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.

Products from Kingspan Insulation’s Kooltherm and Therma ranges have helped to transform a derelict water tower in North Yorkshire into a striking family home, as featured on Channel 4‘s Restoration Man. By using insulation that delivers outstanding thermal performance from minimal thicknesses, the owners have been able to create a home that is not only sensitive to the building’s industrial past, but that functions as a cosy yet spacious family home.

The design philosophy for this project was to create a highly-efficient and architecturally-stunning world class winery for Yealands Estate. Inspired by the landscape, the curved roof mirrors the shape of the nearby rolling hills, and the overall building is reminiscent of traditional family run countryside wineries.The building features a highly insulated envelope and is considered one of the most environmentally friendly wineries ever built.
