"cavity wall insulation"

The Chilterns Lifestyle Centre in Amersham will feature a range of leisure, sports and community facilities. As each of the activities taking place will require different indoor temperatures – warm or cool – to keep users comfortable, a high-performing insulation solution was essential.Thermal performance wasn’t the only factor in insulation choice for specialist façade contractor Teampol. At just 14m high, the Chilterns Lifestyle Centre doesn’t fall under current fire regulations banning combustible insulation. But non-combustibility was still a key consideration in installing 2,300m2 of Knauf Insulation’s OmniFit® Slab 35 and Rocksilk® RainScreen Slab.“The original specification was for a combustible phenolic insulation,” said Scott Millins, Quantity Surveyor at Teampol. “But there’s always that concern at the back of my mind of ‘what if the worst happened?’ so I will only use non-combustible insulation whatever the height of the building. Plus, there’s a very real possibility that regulations may change again, and I don’t want my projects to need costly remedial work further down the line.”“I approached several manufacturers for a non-combustible alternative. They weren’t able to do the calculations quickly and couldn’t meet the U-value required without increasing the depth of the rainscreen insulation from 80mm to 120mm, which would have impacted the whole design.”By this point, finding a solution was critical, otherwise the entire project would be delayed. Millins approached Knauf Insulation’s Specification Team for support and product advice stressing the need for a fast turnaround. Within 24 hours, the Technical Support Team had conducted 3D U-value calculations and a condensation analysis.They recommended 150mm OmniFit® Slab 35 for the steel frame stud with Rocksilk® RainScreen Slab for the façade. Crucially, this combination meant they were able to meet the U-value of 0.22 W/m2K and keep to the original 80mm insulation depth specified for the rainscreen.“Knauf Insulation were fast, responsive and helpful,” explained Scott. “From our initial conversations, it was clear they had the technical expertise, and this was backed up by an extremely quick turnaround for all the supporting calculations that I needed to move forward with the job.”Both OmniFit® Slab 35 and Rocksilk® RainScreen Slab offer exceptional 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. Rocksilk® RainScreen Slab is BBA certified for use at any height.OmniFit® Slab 35 and Rocksilk® RainScreen Slab also have excellent sound absorption characteristics which will help ensure that any sports and community activities taking place inside don’t disturb local residents.As well as Knauf Insulation’s technical advice and product performance, the consistency and quality of the two products have impressed Millins and the Teampol installation team.“Installation of both OmniFit® Slab 35 and Rocksilk® RainScreen Slab has gone extremely smoothly. They’re both quick and easy to fit and it helps that these Mineral Wool products from Knauf Insulation are nice and soft – our installation team love working with them,” added Millins.This softness is thanks to the ECOSE® Technology, Knauf Insulation's unique bio-based binder which contains no added formaldehyde or phenol. Products made with ECOSE® Technology are also easy to handle, 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, so it is kinder to the environment too.Thanks to Knauf Insulation’s rapid response and technical support, Teampol was able to meet the thermal requirements for the Chilterns Lifestyle Centre project using non-combustible insulation – all while keeping to the tight build schedule.

Delta Registered Installers, Bensleys provided a waterproofing solution on an iconic Brighton structure.Steeped in history and thought to be built on the original Brill Baths site, sits Clarendon Mansions. This large, detached structure is thought to have been built in 1870 by Charles Brill during the Brighton boom.The four-storey building facing Brighton’s famous sea front, was originally constructed as a hotel.Numerous refurbishments over subsequent periods of time, saw the structure move from a hotel to a public house, with the basement area being unoccupied for nearly a decade.The basement area boasts large, vaulted areas to the south and west elevation, with the south-side possibly being part of the original Bath structure.Bensleys were instructed by the main contractor, Pilbeam Construction on behalf of Evolution Architects, to help design, specify and install the waterproofing system.There’s no one-size-fits-all when it comes to waterproofing design. With the basement suffering from water penetration, Bensleys worked with the design team at an early stage of the project to ensure the right approach be taken, which included multiple factors such as: customer requirements, standards, robustness, cost, resources, time, skill required, safety and expectations of ground water which all translated into a design solution.

“We needed extremely detailed U-value calculations, and Knauf Insulation is one of the best at supplying these”, Paul Mann, Sales & Pre-Construction Director, TAC Projects.3,000m2 of Knauf Insulation Rocksilk® RainScreen Slab is providing essential comfort and fire safety for vulnerable residents in a new development on a challenging site.Quantock House, Taunton is a new collection of 88 assisted living apartments set over nine storeys in a prime position at the heart of Somerset’s county town. It is the latest development from Platinum Skies, part of the Affordable Housing and Healthcare Group (AHH). Specialist contractor TAC Projects was tasked with the technical design and overall delivery of the façade.There were two essential considerations for the insulation specification. The first was that it had to be non-combustible, with a Euroclass A1 reaction to fire classification. “We never use combustible materials on any residential façade, regardless of height” explained Paul Mann, Sales & Pre-Construction Director, TAC Projects. “This is especially important in developments with vulnerable residents.”The second was thermal performance. The façade had to achieve a U-value of 0.18W/m2K, but with a complex design including acute angles between elevations and an undercroft car park, detailed calculations would be needed to support the specification. This was not just for best practice; to insure the building, the NHBC insisted on detailed supporting data for all products used in its construction.“The original specification from AAH’s architect was for Rock Mineral Wool. Our need for more robust U-value calculations, among other reasons, led us to choose Knauf Insulation Rocksilk® RainScreen Slab” said Paul. “That meant we were able to get 3D U-value calculations from its Technical Support team”.3D U-value calculations provide a much more detailed and accurate model of a building’s thermal performance. They give contractors, architects and third parties valuable reassurance that the interactions between different building elements have been properly considered, such that the calculations will more accurately reflect the energy efficiency of the building in the real world.Rocksilk® RainScreen Slab is a non-combustible Rock Mineral Wool insulation that offers exceptional thermal and acoustic performance. It achieves Euroclass A1 reaction to fire classification, and is BBA certified for the broadest range of build-ups of any rainscreen solution on the market.It is designed to be easy to install correctly. Slabs are robust enough for easy manoeuvrability, but capable of flexing to adapt to imperfections in the substrate and to interlock when butted together. This is critical as it prevents the air gaps that can occur when using other, more rigid types of insulation; gaps which can compromise thermal, fire or acoustic performance.Rocksilk® RainScreen Slab is also 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 70% less energy-intensive to manufacture than traditional binders, 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.In addition to the 3D U-value calculations, the project required an extra level of service and logistical support. With no storage space on site, and only room for one lorry at a time, deliveries had to be meticulously planned to keep the job running smoothly. Distributor CCF, who supplied the insulation, worked closely with TAC Projects to schedule deliveries in line with their plan of works.“Our business is all about trust” continued Paul. “AAH is trusted by its customers to provide safe and warm homes. We’re trusted by them to build non-combustible, energy-efficient façades. And in turn, we trust Knauf Insulation to give us the innovative products and service we need to do that.”Thanks to these trusted relationships, the residents at Quantock House will enjoy their new homes in warmth and comfort, with the peace of mind that comes from knowing they are built using sustainable, non-combustible materials.

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.

This multi award-winning museum has taken form with a copper clad envelope featuring high quality rainscreen insulation and pitched roof insulation.

“How good is Knauf Insulation’s specification and technical support? Let’s put it this way, I’ve used Rocksilk® RainScreen Slab for every façade project since.”- Nikesh Patel, Façade Design Manager at A2O Cladding The Weald of Kent Grammar Annexe extension is a new three-storey satellite facility for Tunbridge Wells Grammar School for Boys in Sevenoaks. It comprises state-of-the-art classrooms for a cohort of 90 boys. A2O Cladding were appointed by Willmott Dixon to deliver the technical design and installation of the façade, which is finished with a white and grey silicon render set against a red Corium brickslip façade. One of their first tasks was to finalise the insulation specification based on three key requirements: thermal performance, non-combustibility and sustainability. Meeting the thermal performance challenge The first factor, the thermal performance of the rainscreen façade system, initially proved more difficult than expected. Nikesh Patel, Façade Design Manager at A2O Cladding explained: “U-values provided by the architect for a rainscreen façade system are a bit belt and braces because they’re based on assumptions. So, once we’ve confirmed the sub-structure, we redo them to ensure they’re an accurate representation of the building’s thermal performance.”   “The problem is the manufacturer we were working with couldn’t deliver the U-value of 0.18 W/m2K because they didn’t have the right software.” For most applications, the simplified methodology used for calculating U-values is sufficient. But it is not recommended for rainscreen façade systems, because it does not take into account the complex interaction between the Steel Frame System (SFS) and the insulation. Instead, a blanket correction factor is applied, which can lead to the over-specification of insulation – as it had in this case. To prevent this, 3D U-value calculations should be used. They thermally model the build-up based on the complex interaction between the insulation and the rails and brackets. This ensures greater accuracy giving the specifier a true picture of how the build-up will perform after construction, so it matches its design. But most manufacturers don’t have the capability to undertake these complex calculations in-house, so outsource the service to a third party at a cost to the contractor. Before they went down this route, A2O Cladding asked project architect Bond Bryan for advice, who suggested they contact Knauf Insulation.  “We’d not used Knauf Insulation before so didn’t know the standard of their technical support. The biggest tick in the box was they do free 3D U-value calculations – it really helped to keep the project on track.”  Using these calculations, the Knauf Insulation Technical Support Team recommended Rocksilk® RainScreen Slab for the façade insulation. The product has a thermal conductivity of 0.034 W/mK and crucially, a depth of just 150mm would meet the required U-value.  They also recommended 150mm of Rocksilk® EWI Slab with a thermal conductivity of 0.036 W/mK to insulate the rendered external walls. A2O Cladding also decided to use Knauf Insulation’s OmniFit® Slab 35 to insulate the junctions at roof level to ensure continuity of insulation. Fire safety at every height All three products have the best possible Euroclass A1 reaction to fire classification, so will not contribute to the development or spread of fire, should it occur. This meant they met the second specification factor, non-combustibility.  “The Annexe extension is under 18m tall but that would never influence our choice of insulation material. The A2O ethos is that we don’t touch combustible stuff when there are suitable non-combustible solutions available. I mean why would you introduce that risk? Using Mineral Wool insulation gives us, and the school peace of mind.”  Patel goes on to explain that Willmott Dixon has a reputation for quality and will only authorise the use of tested and certified systems. “As the façade contractor, it’s our job to ensure the quality of the supply chain. The fact that Rocksilk® RainScreen Slab is BBA certified for use in high rise buildings and for so many different build-ups meant it met the rigorous standards demanded for the project.” A focus on sustainability But choosing suppliers isn’t just about performance and fire safety. The third factor in the specification process was sustainability.  “As we finalise the technical design, we need to provide Willmott Dixon with a Technical Submittal for every product, and this includes details of its green credentials. It was another example of how Knauf Insulation makes things simple for contractors. They have EPDs for every product and all the relevant ISO standards, so our insulation specification sailed through.” As well as producing products that improve the thermal efficiency of buildings, Knauf Insulation has been taking steps to reduce the carbon footprint of its products. One example of this is its unique bio-based binder, ECOSE® Technology, which 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 binders, so it is more environmentally friendly. From technical support to performance and sustainability, Knauf Insulation scored top marks in all categories – which meant that A2O Cladding didn’t need to compromise on any of their specification requirements or criteria. 

ChallengeBREEAM ‘excellent’ was a key requirement for this project. As a European centre for bioenergy research, Aston University was keen to maintain the sustainable ethos of EBRI within the building itself and make improvements wherever they could be accommodated.SolutionKnauf Insulation worked closely with Associated Architects to specify the correct rainscreen insulation product to meet the necessary requirements.The insulation layer is a fundamental component of any successful rainscreen cladding system and rock mineral wool insulation delivers a number of advantages in this type of application. Knauf Insulation’s Rocksilk® RainScreen HD Slab in a bespoke 120mm size was ideal for the project, delivering exceptional thermal, fire and acoustic performance.Insulation was specified with the help of Knauf Insulation’s regional specification manager Marc Lawson and Technical Advice and Support Centre (TASC). To successfully mitigate the differing dimensions of the constituent elements of glass channel, blockwork substrate and insulation, a smaller than standard slab size was specified, allowing for the edge of the slabs to align behind the joints in the glazed façade, providing an aesthetically pleasing appearance.The early involvement of the regional specification manager in the project and their relationship with the architects and client at the concept stage, made for a very smooth delivery and ensured the required U-value of 0.22W/m2K would be achieved without the need to re-design elements later in the project.Knauf Insulation’s Rock Mineral Wool products deliver exceptional environmental performance and are manufactured using the innovative ECOSE® Technology - a revolutionary, bio-based, formaldehyde free binder technology that is based on rapidly renewable materials, rather than petro- based chemicals. This was a key reason to the insulation being specified for this exceptionally sustainable project."Sustainability is at the very heart of all we do at Aston University. We are delighted with the results: an iconic building that conducts sustainable research in a truly sustainable environment." Alan Charters, Executive Director of Capital Development at Aston University

Sto has supplied the StoTherm Mineral K external wall insulation system with StoLotusan render for the new Day Case and Eye Unit building at Chorley and South Ribble Hospital. Specified by Gilling Dod architects of Chorley, who worked closely with the main contractor Tilbury Douglas, the StoTherm Mineral K system combines impressive insulation with excellent fire protection characteristics. With an A2-s1, d0 reaction to fire classification in accordance with BS EN 13501-1, the non-combustible mineral fibre insulation is fully bonded to the substrate and therefore no additional firebreaks are required. Ideal for both new-build and refurbishment projects, its efficient single-leaf construction also means that interior space within the building is not reduced.  For this project, the system’s mineral fibre insulation boards were secured to the lightweight steel frame and sheathing board substrate with mechanical fixings and StoLevell Uni adhesive and levelling mortar. A StoLevell Duo Plus reinforcing coat embedded with Sto-Glass Fibre Mesh was then applied to the face of the insulation boards, with StoLotusan and StoSilco renders used for the final finish on different sections of the building, using light colours from Sto’s architectural colour range.  StoLotusan is the only render available that uses Sto’s patented Lotus-Effect® technology which delivers impressive water and dirt repellence. It forms a unique surface texture, similar to that of the lotus leaf, that causes the rainwater to run off the render quickly and easily, removing any dirt or dust as it goes. Providing outstanding resistance to the growth of algae and fungus, the building will retain its looks for many years to come.  The new Day Case and Eye Unit is the result of a major £17.5 million investment in developing enhanced ophthalmology and day case services. The new Day Case and Eye Unit now offers an extensive range of diagnostic and treatment facilities for patients with medical eye conditions.

One Hyde Park, owned by CPC Group, is a high-end residential and retail park. Due to the nature and standard of the construction, developers required the highest quality tools, equipment and materials to construct the building. The ambition was to keep the design lines sleek, elegant and spacious, while still achieving the required high thermal performance expected in in a modern prestigious development in the heart of London. Insulating the floors introduced another level of complexity and so the search for something that was up to the challenge began.After meeting with developers, our experts concluded that SuperFOIL SFUF would be the most practical and efficient solution to the project. With a slim profile of just 6mm and R value of 0.8, SFUF gives a great solution where floor depths are limited. SFUF has a slightly different build-up to our typical roof / wall products in that it doesn’t include layers of wadding, this makes it much slimmer and less compressible, making it an ideal combination for solid floor applications. Unlike our other products, SFUF is also typically installed with no air gaps which, again, contributes to its slim profile. The top layer of SFUF is a polythene membrane which provides protection allowing it to be screeded onto directly with no need for additional layers to be installed. This also makes SFUF ideal for use with underfloor heating systems. The application of SuperFOIL SFUF was a success and the building was finished in 2010. Starting at £20million, One Hyde Park residential properties began selling soon after the completion of the complex. SuperFOIL SFUF provided a solution to achieve a high level of thermal performance in this prestigious development. SFUF has an impressive thermal r-value achieving excellent performance in a minimal amount of space

As part of the £17.6 billion Crossrail project, Tottenham Court Road underground station was given a major transformation. Located in the heart of London’s West End, Tottenham Court Road was expanded with a new underground station and ticket hall and a second integrated ticket hall.Due to the huge reconstruction of the the station, it was in need of a modern, high performance and non-combustible insulation solution which wouldn’t have a visible impact on the overall design of the station. A combination of attributes that traditional insulation products struggle to deliver.

SOYO Leeds is a £300 million mixed use scheme that creates a new neighbourhood adjacent to the city’s cultural quarter.Designed by DLG Architects for Caddick Construction and Moda Living, SOYO Leeds will comprise residential and student accommodation, a hotel, restaurants, bars and offices. And at the heart of this new cultural centre is 10,000m2 of Knauf Insulation Rocksilk® RainScreen Slab.During the construction of the scheme’s 515 hotel-style rental apartments, rainscreen contractor Axis Envelope Solutions needed to source suitable, compliant insulation. So, it consulted Knauf Insulation, the UK’s only manufacturer of Glass and Rock Mineral Wool insulation, about which solutions would meet the required thermal and fire performance specification.Knauf Insulation’s Specification Team reviewed the architect’s drawings which included a build-up featuring a steel top hat. The company’s Technical Support Team then undertook 3D U-value calculations completed in line with BS EN 10211 to ensure the finished building’s performance matched the initial design.Because 3D U-value calculations are done in-house, the team were able to turn around the complex calculations in the time frame required.Once the calculations had been performed, Knauf Insulation recommended 180mm Rocksilk® RainScreen Slab as the optimal solution to meet the thermal requirements of the build.As well as exceptional thermal performance, Rocksilk® RainScreen Slab is highly sound absorbent with excellent sound reduction capabilities. It is 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 it meets the requirements of building regulations in England and Wales banning the use of combustible materials on all buildings over 18m. In addition, Rocksilk® RainScreen Slab is British Board of Agrément (BBA) certified for use in high rise buildings and for the broadest range of thicknesses and build-ups of any rainscreen solution on the market.Rocksilk® RainScreen Slab 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 70% less energy-intensive to manufacture than traditional binders, 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.Rocksilk® RainScreen Slab has been designed for ease of use. It is robust which makes it is easy to manoeuvre into place and it can be installed either way round without compromising performance. The Mineral Wool knits together and adapts to imperfections in the substrate, preventing air gaps that compromise thermal, fire and acoustic performance.Thanks to the responsiveness of Knauf Insulation’s Specification and Technical Support Teams, Axis Envelope Solutions was able to keep to the tight schedule required. As a result, the new tenants of the luxury apartments at SOYO Leeds will be able to enjoy homes built to provide the highest level of thermal, fire safety and acoustic performance in the centre of the city’s newest cultural hub.

Gulson Road is a new state of the art student accommodation block in the heart of Coventry’s university district. With 462 rooms, shared study areas, a common room, gym and staff management suite all set over eight storeys, fire safety was of the utmost importance.With this in mind, the architect, Stride Treglown, specified that Rock Mineral Wool should be used to insulate the rainscreen façade to comply with building regulations, which ban the use of combustible materials on all buildings over 18m tall.Knauf Insulation’s Technical Support Team undertook 3D U-value calculations on behalf of main contractors Robertson Construction and recommended 150mm Rocksilk® RainScreen Slab to achieve a U-value of 0.18W/m2K.Rocksilk® RainScreen Slab has a thermal conductivity of just 0.034W/mK. It is non-combustible with the best possible Euroclass A1 Reaction to Fire Classification rating, so will not contribute to the development or spread of fire should it occur. It is BBA certified for use in high rise buildings and the broadest range of build-ups of any rainscreen solution on the market.As well as exceptional thermal performance and fire safety, Rocksilk® RainScreen Slab provides high levels of sound absorption.Rocksilk® RainScreen Slab is easy to install correctly. The slabs interlock and adapt to minor imperfections in the substrate eliminating air leakage, which can reduce thermal and acoustic performance. It is also robust and durable with a water repellent additive to preserve its integrity while exposed during construction.Rocksilk® RainScreen Slab 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 70% less energy-intensive to manufacture than traditional binders, so it is more environmentally-friendly.Products made with ECOSE® Technology generate low levels of dust and VOCs (volatile organic compounds) and have been awarded the Eurofins (Gold) certificate for Indoor Air Comfort.Thanks to the enhanced thermal and acoustic performance from Knauf Insulation’s Rocksilk® RainScreen Slab, students at Gulson Road will enjoy warm, quiet, safe and sustainable flats to study, socialise and sleep in.

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.

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.

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 National College for High Speed Rail contains a variety of learning spaces inside a visually striking yet simple building shell formed from two intersecting blocks.

The boards were fixed directly to the soffits using thermally broken fasteners, making installation quick and simple. Kingspan Kooltherm K110 Soffit Board is a premium performance insulation board. It achieves a thermal conductivity of 0.018 W/m·K across all thicknesses.

The Oak Cancer Centre at The Royal Marsden’s Sutton site is a state-of-the-art research and treatment facility, designed to bring the hospital’s 400-strong research team and its clinical care facility together under one roof. Specialist brickwork contractors, Lesterose Builders, were appointed by main contractor ISG to design and build the 2,800m2 masonry façade. As a result, they were responsible for ensuring the façade complied with the relevant thermal and fire safety regulations. The time and cost challenge The architect’s specification named a rock mineral wool product, but when Sam O’Keefe, Commercial Manager at Lesterose Builders, tried to place the order, there were two problems. He explained: “The first issue was availability – there was an eight to ten week lead time due to materials shortages. And the second issue was cost. We discovered the original insulation manufacturer had two planned price increases, and the extended lead time and phased delivery schedule meant that the Oak Cancer Centre project would be hit by both.” These two issues would not only delay the build, but would push it significantly over budget. So Lesterose Builders needed another insulation solution. Meeting the specification Lesterose Builders turned to Knauf Insulation, a fellow member of the Association of Brickwork Contractors (ABC). Knauf Insulation’s sales team looked at the specification and was able to offer an equivalent – 200mm Rocksilk® RainScreen Slab.  Rocksilk® RainScreen Slab is a rock mineral wool insulation product with a thermal conductivity of just 0.034W/mK, which meant it would meet the U-value of 0.21W/m2K. It is also non-combustible with Euroclass A1 reaction to fire classification, which means it will not contribute to the development or spread of fire should it occur. It is British Board of Agrément (BBA) certified for masonry façades at any height as well as for the broadest range of build-ups of any rainscreen solution on the market. This meant Rocksilk® RainScreen Slab was suitable for use in the Oak Cancer Centre because it complies with building regulations that ban the use of combustible materials in the walls of relevant buildings over 18m tall. In addition to fire safety and thermal performance, Rocksilk® RainScreen Slab offers excellent sound reduction characteristics. Crucially, Knauf Insulation was able to meet both the schedule and cost parameters for the project. “Once we had confirmation that Knauf Insulation could match the specification and deliver to the planned timescales and budget, it was then a case of getting the architect’s approval. This went extremely smoothly. We just made a technical submittal with the datasheets and environmental product declaration (EPD) and Rocksilk® RainScreen Slab was approved for use without any queries.” Ease of installation The seven-full loads of insulation were purchased through Parker Building Supplies. These were delivered to the site in eight phases in line with the schedule of works. The product is designed to be easy to install correctly. Superior robustness and durability mean it can be manoeuvred easily into place. And unlike some competitor products, it can be installed with either face of the slab against the substrate, speeding up installation and preventing incorrect installation. Furthermore, the natural flexibility of rock mineral wool means it adapts to minor imperfections in the substrate, while slabs knit together when tightly butted, eliminating air leakage that could reduce thermal and acoustic performance. Rocksilk® RainScreen Slab is also 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 70% less energy-intensive to manufacture than traditional binders, so it is more environmentally friendly. 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. Construction work is known for its challenges, particularly around budgets and schedules – but thanks to Knauf Insulation’s Rocksilk® RainScreen Slab, Lesterose Builders was able to overcome both these issues and meet the required specification factors for the Oak Cancer Centre. 

ChallengeThe London Stadium (formerly Olympic Stadium) and home of Premier League football club West Ham United, required an insulation solution that would not only upgrade the thermal and acoustic performance of the HVAC and service pipe areas, but also one that could meet the overall environmental demands of the project.SolutionAfter a series of consultations with the main contractor, Knauf Insulation developed a bespoke, one product solution, which met all requirements and helped to reduce engineering costs and installation time.23,000m2 of Rocksilk® Soffit Linerboard Standard was installed in the different elevations of the stadium, from level two to the lower ground level of the West Stand.Manufactured with ECOSE® Technology, Rocksilk® Soffit Linerboard Standard is a laminate of a compression resistant, non-combustible Rock Mineral Wool slab with a variety of aesthetic finishes designed to provide a robust faced solution suitable for installation in semi-exposed environments such as stadiums like this.The project was completed before West Ham’s first competitive game at the London Stadium in August 2016."The insulation product knits together to prevent open joints, which helped us to maximise the thermal efficiency of the insulation."Kunal Vekaria, Project Manager at HLS Installations

BackgroundLocated in a prominent location on the Morecambe seafront, the Broadway Apartments project was large new build steel frame apartment block.A challenging project to be involved with, as M H Stainton Homes wanted to create an iconic building on a corner location. The steel frame was key, combined with curved glazing on the corner elevation of the building. Then a lightweight cladding solution was required for the rest of the façades.K Systems approved installer M & M Façades were contracted to complete the exterior wall insulation and rendering of the 8-storey residential building.Our ServiceWe worked in close partnership with M & M Façades throughout the duration of the project. The K Systems Technical team offered on-site technical and installation support throughout the build process and supported the M & M Façades team at all stages of the project.As the building is over 18 metres, a bespoke specification was produced to ensure compliance with the current building safety regulations.A direct fix system suitable for steel frame structures and all building heights was specified, ensuring the safety of both the building and future residents.Technical Project DetailsAfter numerous design meetings the K Systems Direct Fix M (Mineral Wool) EWI system with a Silicone Render (TC 15) finish was chosen, meeting the requirements of M H Stainton Homes.This system provides high levels of fire resistance and non-combustibility bringing the apartments in line with mandatory Government requirements for buildings over 18 metres tall.We specified the use of multiple thicknesses of insulation boards (50mm, 100mm and 170mm) to allow for the line and level of the steel frame. A U-value of 0.28 W/m²K was achieved, meaning the residents will enjoy thermally efficient homes.For the finish Silicone TC 15, our high-performance thin coat render, was used. With the coastal location, this durable, weather resistant finish offers an eye catching, clean design, creating a modern and crisp aesthetic. Its hydrophobic properties provide a low-maintenance finish.We delivered a safe, thermally efficient, eye-catching design with a long-lasting finish that residents will appreciate for years to come.

Skyfold has launched a pioneering, fully automatic, moveable wall solution into the UK.The Skyfold Prisma, which is exclusively available from leading moveable wall specialists, Style, is a new and streamlined glass vertical partition which not only allows light to shine in but does so without the use of any wall or floor tracks, rendering it completely invisible when stored in the ceiling.“This is a real breakthrough in moveable wall technology from our global manufacturing partners, Skyfold,” said Style’s group managing director, Julian Sargent.“As a fully automated, acoustic glazed moveable wall that stacks into a ceiling cavity, its slim metal frame, clean lines, and sleek design will add elegance and an abundance of light to a wide range of rooms. We see demand being very strong in the corporate, hospitality, education, healthcare, religious and public sectors.”Skyfold Prisma's glass panels combine with a minimalist frame to allow light penetration into otherwise dark rooms and corridors, creating an open plan feel to any area, positively impacting both mood and productivity.With an impressive 52 Rw dB acoustic rating, Prisma also delivers privacy between divided spaces, allowing confidential meetings, classes, and collaborations to occur simultaneously. With space always at a premium, the panels of this innovative new partitioning wall cleverly ‘taper’ down into position, making it suitable for restricted areas or where there is potential for obstructions. Further maximising space, when not required, the partition can be quickly retracted into the ceiling cavity where it is neatly stored, completely out of sight. Skyfold has announced that Prisma is available in a variety of materials including glass, frosted glass and solid panels, with almost any combination being possible. Solid elements can be finished in fabric, vinyl, paint, laminate or even marker-board, allowing a true showcase feature to be created that is both superbly aesthetic as well as highly functional.

Lignacite have established a reputation for their extensive range of high quality commodity and architectural facing masonry blocks capable of improving acoustic, sound absorption and sound insulation values. Sound absorption is an extremely effective method of lessening the echo and noise within a space, room or building. Products designed to absorb sound are normally made from soft materials which act to soak up noise as it hits the surface. However certain blocks manufactured by Lignacite perform considerably better than would be expected for a denser material.

Recently opened, the Engine Shed is Scotland’s dedicated building conservation centre, based in Stirling. Working with contractor, ESH Border and architect Reiach & Hall, Style Scotland installed a Skyfold operable wall to quickly separate the exhibition space from the auditorium, allowing educational seminars to be conducted in privacy whilst the rest of the space remains open to the public. Skyfold, a hugely innovative partitioning solution, is a vertical-rising moveable wall that retracts into the ceiling cavity at the turn of a key, creating an acoustic barrier of up to 59dB Rw.

Beneath the streets of Central London lies a network of Grade 2 Listed underground vaults. As Newton Specialist Contractors, Stonehouse were called in to waterproof four of these impressive structures and turn them into a completely dry commercial space. The four vaults were situated just North of the River Thames in Central London, a short walk from such famous landmarks as Smithfield Market and St Paul's Cathedral.The Grade II Listed structures are each over 4 metres in height, and form part of an impressive below-ground infrastructure network. Newton Specialist Contractor Stonehouse were asked to waterproof four of these impressive vaults for the multinational service provider KPMG, in order to turn them into useful commercial spaces.When waterproofing historic vaults such as these, the Newton CDM System provides the ideal solution as it is maintainable, requires minimal fixings and therefore avoids damaging the structure, and crucially is deemed as reversible should the structure need to be returned to its original condition in future.As an experienced contractor, Stonehouse proceeded with an expert installation of a full CDM System to the tricky vaults, including:508 Mesh membrane to the walls, for a direct plaster finish508 membrane and Fibran XPS 500-C insulation boards to the floor.Basedrain channels to direct any captured water towards two Titan-Pro sump chambers, each containing two NP400 pumps.Victron Inverter and a NorthStar battery for reliable backup power.Stonehouse completed an extremely complex and detailed cavity drain installation with precision, resulting in an exceptionally neat waterproofing system, and proving the benefits of using a specialist waterproofing contractor.

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. 

As part of an extensive refurbishment at the School of Biomedical Sciences, Newcastle University, Style installed the unique Skyfold dividing wall system, delivering fast and effective flexible room configuration to laboratory teaching facilities. Skyfold is a fully automatic, acoustic moveable wall that's housed discreetly in the ceiling cavity and offers unparalleled acoustic integrity of 59dB Rw. “The wall has exceeded our expectations acoustically, visually and practically,” confirms Dr Alison Gregory, technical manager, School of Biomedical Sciences at the University. “We can run independent activities in adjoining labs with large numbers of students with virtually no sound transfer between rooms.

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. 

The Cartcraigs high-rise project located in the heart of Southside Glasgow was a rewarding project to be involved with allowing real transformation and change in several key areas.The tower block was originally built in the 1960’s with a grey cladding finish but due to decades of inclement Scottish weather, the building was weather-beaten, tired and dated. With its stature and prominent location, the building should have been an attractive living option in Southside Glasgow but instead was unappealing to potential residents, and in desperate need of modernisation.Rising fuel prices and the current poor thermal performance of the tower block, meant it was extremely difficult and expensive for tenants to heat their flats – so much so that many occupants were considered in a state of fuel poverty.In collaboration with MAST Architects and our approved installer PWM, we designed a façade solution that not only significantly improved the thermal performance of the building, but transformed Cartcraigs aesthetically creating a modern, fit-for-purpose living space.A complete revamp which has given the building a new lease of life and delivered safe, modern and energy efficient homes for the residents.Our ServiceDue to the scale of this project, the congested location and small site footprint, we had to work closely with our approved installer, main contractor, and local authority to ensure minimum disruption to both the residents of Cartcraigs and residents of the surrounding area.Delivery routes and schedules were agreed to ensure consideration for local residents throughout the project.As part of our service commitment, our Site Application Specialists carried out regular site visits to ensure our system was installed to the highest standard and in line with our specification.They were available throughout the duration of the project to provide technical guidance, installation support and ensure the highest levels of quality. This allowed the K Systems Technical & Logistics Teams to support the schedule of the project with timely delivery of materials to site and ensuring there were no delays during the installation and inspection processes.“In conjunction with the Architects we approached K Systems to design a system to comply with fire regulations and offer a solution to make the look of the building more aesthetically pleasing along with making it a point of interest within the Southside area. Great site support was provided by Ally along with Technical/Service support from Jim and Martin. The team at PWM look forward to working on our next project with K Systems.”Kevin Fox, PWM Projects ManagerTechnical Project DetailsThe original façade incorporated a 25mm cavity with reinforced concrete inner leaf shaped panels, which could be seen beneath the then grey façade panelling. Wheatley Group, the client, had requested a clean, crisp, and smooth finish that would also comply with Scottish Fire Regulations.After numerous design meetings taking into consideration client requirements, budgets, and timeframes, we put forward our industry-proven K Systems M Silicone EWI system. The system was designed using 160mm non-combustible mineral wool insulation to meet the 0.18 (W/m2K) U-value requirement, making it the perfect choice for the refurbishment to combat the heating issues faced by residents and futureproof the building as a viable living space for years to come.Bespoke technical detailing and rigorous adherence to our high-rise policy ensured a high performing system with an A2 non-combustible fire rating, complying with all safety regulations for buildings over 11m in Scotland. The 160mm insulated grey and white façade delivered a really attractive high-rise that will now better withstand the Scottish elements.The finish used was our high-performance thin coat render, Silicone TC15. The contemporary colours of grey and white were chosen from our wide range of colours which visually transformed the 17-storey building. Our polymer rich Silicone TC15 allows ease of application, and its hydrophobic properties will provide a clean, crisp and low-maintenance finish for years to come.Our specification included bespoke detailing to provide solutions for Cartcraig’s individual retrofit design challenges. We also commissioned wind load calculations and fixing pull-out tests to determine optimum fixing patterns to anchor the EWI system to the different substrates. Ultimately, a safe, thermally efficient and visually appealing result was achieved.“K Systems provided a great overall package from the inception of this project with design advice, through the technical stages, with assistance through specification and then with the provision of weekly reports and checks once the project got on site. Cartcraigs, being a high-rise block needed monitoring and adherence to the project specification, and having the K Systems team providing regular on site checks gave the design team the assurance that all requirements were being met.”David Locke, Mast Architects

The Bishop Auckland refurbishment project, is a stellar example of K Systems ability to harness years of expertise with forward-thinking innovation to meet the needs of its clients.Durham Homes commissioned K Systems to refurbish its residential development of 120 terraced houses. The primary aim of this project was to improve the thermal performance rating of each home. The challenge for K Systems was to provide a suitable EWI solution whilst retaining the character of the homes by replicating the existing brick and stone walls.Due to this unique mix of required finishes, we were presented with an extremely complex project that required careful attention of several aesthetic and design considerations.Having a good reputation for matching systems with finishes to deliver clients’ visions, we worked in collaboration with our approved installer Westdale Group, to scope out the project and specification in fine detail, with particular focus on insulating properties and aesthetic.These poorly insulated brick and stone terraced houses were given a thermal upgrade to enhance occupier comfort. An attractive brick render finish was used over insulation to provide an aesthetic finish that is in keeping with the current street scene.This satisfied the client’s requirements whilst providing a total revamp for the properties, which has resulted in energy efficient and aesthetically pleasing homes for the client and residents.Our ServiceWe worked in collaboration with Durham Homes and approved installer Westdale Group to upgrade these poorly insulated brick and stone terraced houses and deliver a total revamp of the properties, resulting in thermally efficient homes.The project was completed with minimal disruption to existing residents, and due to forward planning and regular site visits by an experienced K Systems project manager, where processes and progress were monitored and evaluated, the project was completed within the agreed timescale.Our Application Specialists visited the site regularly throughout the project working in collaboration with the approved contractor to ensure correct installation and detailing.As a result, we delivered an excellently designed and expertly executed refurbishment, that exceeded the expectations and requirements of the client, Durham Homes, and the residents of the newly improved homes.Joe Rogers at Westdale Group, said:“To deliver such a large project (120 houses), it requires multiple teams to work seamlessly together and have absolute trust in the other’s skill, vision, and judgement. That’s exactly what we had with K Systems on this Bishop Auckland project. The team’s innate understanding of pairing systems with finishes for optimal performance is second to none and together we delivered a best-in-class refurbishment which was an absolute pleasure.”Technical Project DetailsEffective demand planning and technical detailing ensured that the Durham Homes project was completed on time in March 2022.Having comprehensively assessed the project requirements, taking into consideration thermal u-value target, aesthetics and cost, our K Systems E BrickRend EWI system was specified. This high-performing system is lightweight utilising expanded polystyrene (EPS) panels that are enhanced with graphite to further enhance thermal performance.The E BrickRend system has a fire performance rating of B2-s1,d0. It’s low moisture absorption and resistance to mould growth ensures a high level of durability.The system was specifically tailored to meet the thermal performance criteria of the project. Utilising 90mm EPS panels, the target U-value of 0.30W/m2K was achieved, delivering the benefits of improved thermal comfort and lower heating costs for residents, whilst helping the local authority achieve it’s environmental carbon reduction targets.Several finish options were considered to meet the client’s requirement of replicating the existing brick/stone appearance of the properties whilst remaining within the project budget.K Systems specified BrickRend, a bespoke, specially formulated polymer render which was colour-matched to the existing masonry. It was then down to the skill of our approved installer to apply pigments to tint and shade the render surface and simulate the appearance of real stonework. The surface is then sealed to provide a long-term durability. A dash render finish was applied to the rear of the Bishop Auckland properties.This particular finish didn’t just ‘fit the bill’ at the time of delivery, but is an economic, durable, lightweight solution, easily applied, with an increased bond strength compared to sand and cement, which will protect the insulation and structural fabric of the homes from environmental deterioration in years to come.This customised finish and attention to detail is a perfect example of how K Systems works with all clients to fulfil any specific design criteria and go above and beyond the standard requirements to deliver superior quality.

BackgroundOccupying a prominent position on the Kingsway, The Curve development is a portfolio of 27 apartments. The key requirement for Cube Homes was to offer residents high quality, low carbon, affordable and sustainable apartments.After extensive planning, K Systems specified a direct fix system with mineral wool insulation and a silicone render finish. Our Direct Fix system for steel frame structures is KIWA BDA certified and provided the ideal solution for these newly constructed mid-rise apartments.Our team designed a façade solution that delivered modern, thermally efficient and aesthetically pleasing homes, meeting the client’s requirements.Our ServiceDue to the number of fixings and the curvature of the property, this was a technical project which required bespoke detailing.In collaboration with Bowker Sadler Architects and our approved installer Profac, we designed a comprehensive specification and were on-site when required, offering Profac technical and installation support throughout the build.The Direct Fix system specified is a cost-efficient solution for steel frame structures, with fewer components for a simpler and faster install. Direct Fix generates exceptional insulation and with a silicone render finish provides high levels of fire rating (A2,s1-d0), allowing Cube Homes to deliver safe and thermally efficient homes.Technical Project DetailsThe EWI needed to be line and level with the ground floor brickwork. To achieve this specific requirement, 300mm mineral wool (which is deeper than available mineral wool) was specified for the project. This meant 110mm and 190mm boards were combined to achieve the required 300mm.This thicker mineral wool meant that the curved elevation on the building was difficult to achieve. The insulation was facetted around the curve and carefully installed by Profac to create a seamless façade. The 300mm mineral wool resulted in a low U-value of circa 0.10 W/m²K, meaning heating costs for the apartments will be minimal and carbon usage will be reduced to a minimum standard.For the finish, silicone render (TC 15) was specified to create a striking curved elevation. Silicone TC incorporates the benefits of silicone technology to provide a water repellent finish with a fresh and modern appearance. The silicone allows water vapour to pass freely through the render whilst allowing the finish to remain weather resistant, making it the ideal solution for a low maintenance, long-term finish.

As residents have a varied degree of mobility, care was taken to ensure a level threshold on all doors to external spaces. To achieve this, whilst keeping the area well insulated, the Kingspan OPTIM-R Balcony & Terrace System was specified. 40 mm Kingspan OPTIM-R Balcony & Terrace System was installed on the terrace below Kingspan Thermaroof TR27 LPC/FM. Kingspan OPTIM-R panels were also installed on the balconies, with matching thicknesses of flex infill strips laid around the edges. A further layer of Kingspan Thermataper TT47 LPC/FM was installed above this, providing a fall to the gutter.

The Hurlford Avenue new build project, situated on the former Garscadden Primary School site, truly harnesses innovation and design. This ‘Modern Methods of Construction’ project, completed in partnership with CCG, showcases technical prowess and constructional excellence.Garscadden Primary School closed back in 2017 but the 1930s school building remained standing. Spotting the potential for something impressive on the site, Glasgow Housing Association proposed a modern replacement – a portfolio of properties.The key requirement was to build modern, energy efficient homes which would provide much-needed affordable housing in the sought-after area of Dumbarton and make a significant difference to the local community.After extensive planning, focusing on matching an appropriate insulation system with a complementary finish, K Systems devised a comprehensive delivery plan using our unrivalled experience and expertise.CCG fabricated the building off-site with timber kits and incorporated elements from our Aricco system, with the final finish being completed on-site. This approach was advantageous for a few reasons, including the speed of construction and a reduction in required labour.Hurlford Avenue is a prime example of our experience with off-site modular builds and our project-specific approach to EWI solutions. We brought Glasgow Housing Association’s vision to life and delivered 28 houses and 42 flats for mid-market rent.Our ServiceThe build of the Hurlford Avenue development wasn’t without its challenges. Precision planning was required to ensure minimal disruption to the residents in surrounding estates. All traffic ways remained free for passage and noise pollution was kept to a minimum.During the build, our team encountered some detailing challenges. However, working directly with the contractor and main contractor, these challenges were quickly resolved by key colleagues within our Technical Team, and the build remained on schedule and of the highest quality.From specification and design to planning, delivery and evaluating, our team transformed a derelict site to a contemporary multi-dwelling development that rejuvenated the Dumbarton area.“I would like to thank everyone on the K Systems technical support team for their contribution in accomplishing the Aricco System project at Hurlford Avenue. The regular visits from senior technicians always go a long way to keeping any project in check and it makes the job of our management much easier by having honest, professional judgement to go back to our guys, with well earned praise on this occasion. Everyone was onboard from the outset in working around any potential difficulties and you will agree it shows in the final results.”Garry Barton, Contractor.Technical Project DetailsAs the client of this project, Scotland based construction company CCG, approached K Systems to provide a suitable façade solution that would complement their design. A build with timber kits and a drained ventilated cavity system was specified, along with a silkolitt thin coat render finish.CCG are renowned for off-site manufacturing (OSM) and manufactured the kits from their production site in near-by Cambuslang. They sourced the correct material according to our exact specification. CCG’s ‘iQ’ System was chosen, which is designed with a fabric-first approach where greater tolerances are determined by fewer junctions and thermal bridges to deliver enhanced U-values and significantly improve airtightness. By incorporating OSM and the iQ system into this project, it is just a small insight into our unrivalled knowledge and expert approach that we take to fulfil the requirements of our clients.For the supporting façade, the K Systems Aricco system was specified - a drained ventilated cavity system perfectly suited for use in low rise buildings, particularly new build projects and timber framed construction. The Aricco system is also the most compatible with offsite/modular construction techniques and boasts an A2-s1, d0 fire rating and therefore complies with the latest building regulations, ensuring the safety of all residents.The finish was just as important as the façade system, with the cost-effective, industry-leading Silkolitt thin coat render specified. Silkolitt renders provide a contemporary finish to new-build applications, something this project very much required to modernise the area. Silkolitt is simple to apply, and its hydrophobic properties makes the render low maintenance. It also has excellent vapour permeability, allowing the Hurlford Avenue properties to breathe and avoid interstitial condensation. It is the most flexible system on the market, making cracking over its lifetime less likely and therefore delivering a pleasing aesthetic with outstanding longevity.The combinations specified by the K Systems team resulted in the build of impressive dwellings boasting a U-value of 0.13W/m ² K – meaning homes were easier and cheaper to heat, a particularly attractive benefit given the current cost of living crisis.
