"roof finish underlays and insulation"

Agar Grove is a multi-award-winning development, created by 5-star housebuilder, The Hill Group for Camden Council, as part of their Community Investment Programme. With a proposed 507 new homes, once complete Agar Grove will be the largest Passivhaus development in the UK.Knauf Insulation’s glass blowing mineral wool Supafil® has been specified for Phase 1C of the project, which comprises 125 homes. We spoke to Hill’s Senior Technical Coordinator, Ben Clarke and Senior Contract Surveyor, Matthew Bricknell about the needs of the project.Prioritising real performancePassivhaus is an internationally recognised building standard, resulting in very high energy efficiency. For the residents of Agar Grove, this will mean greater thermal comfort, alongside reduced energy bills.Achieving the Passivhaus standard requires a complex balance of design factors to create high levels of insulation and airtightness. To ensure their designs would deliver in the real world, it was therefore important for Hill to specify products which would perform as well in situ as they did on paper.As Ben explains, “We chose to use blown-in insulation because of its real-world thermal performance. Installing insulation boards can sometimes mean gaps are left between them, which leads to cold bridges in the build. But that can be more easily avoided with a blown-in product.”To provide further quality assurance, Hill has appointed contractors from Knauf Insulation’s network of Approved Supafil® Installers. Trained by Knauf Insulation’s own Regional Technical Managers, they have the necessary product knowledge and expertise to ensure a quality installation.Using Supafil® will also mean that less product is wasted on-site. When rigid insulation boards are cut to size, offcuts are often discarded because they are difficult to use elsewhere. By contrast, Supafil® has a zero-waste potential. When the cavity is full any excess product remains in the insulation blowing machine hopper, ready to be installed on the next plot, and when the job is complete Supafil®’s packaging can be recycled. Ben says: “As a responsible business, Hill is always looking for ways to reduce waste on our projects wherever we can, and this solution will help us to do that”.Evidencing qualityThe Passivhaus accreditation requires Hill to demonstrate the energy efficiency of Agar Grove, which will involve data collection throughout the build and thermal imaging of the finished product. As Matt explains, “We have a significant quality assurance requirement. We need to be able to show Camden Council that we have insulated the building as specified and that’s not always a simple task – particularly with blown-in solutions which by their nature, are hidden within the cavity.”To help meet this challenge, Hill’s Approved Supafil® Installers will use Knauf Insulation’s app-based site reporting system, KinetiK®. The app allows the installer to select their site and plot number on their mobile device, photograph the elevation, and then scan each pack of Supafil® as it’s installed.Matt continues, “KinetiK® will enable us to confirm that the insulation has gone in as specified. This is essential for our client, but it also gives us confidence too. If areas are missed during an install, there are time and cost implications, so having a tool like KinetiK® will provide us with added assurance that the cavity has been fully filled.” Agar Grove will be the latest in a number of Passivhaus projects which Knauf Insulation has supported.

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 

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

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

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

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

The brief was to replace an existing roof that had reached the end of its serviceable life, with a high performance waterproofing solution and upgrade the insulation in order to meet the University’s energy efficiency policy.

The refurbishment scheme at Buckley View in Smallbridge was completed in March 2022 and is one of a series of demonstrator projects that Rochdale Boroughwide Housing are completing.These projects are part of an ongoing approach to improve the energy efficiency of homes and reduce carbon emissions, helping to identify the best ways to meet Greater Manchester’s 2038 target to be carbon neutral.The scheme has seen 23 bungalows in Buckley View receive investment to help improve the energy efficiency of the homes and reduce carbon emissions using a whole-house, fabric first approach.The work carried out included replacing cavity wall and roof insulation, installing External Wall Insulation (EWI), upgrading ventilation and installing new windows and doors.We worked in close partnership with our approved installer Profac and provided a suitable EWI solution for the project and complementary finish. A brick slip finish was utilised, which was supplied in three colours to totally refresh the facades.The bungalows in Buckley View were totally transformed and will enjoy increased energy efficiency, improved thermal comfort, reduced fuel consumption for residents and, as a result, lower carbon emissions.Our ServiceK Systems prides itself on having an inspiring and effective solution for every style, and this project is just one example of how it provides the flexibility to fulfil any specific design criteria.We tailored the specification process for the project based on the set and very specific requirements of Rochdale Boroughwide Housing and its properties, and every single request / objective of the client was not only met but exceeded in the refurbishment.The design and delivery of the refurbishment not only received 100% satisfaction ratings from all parties involved, but has also gained external recognition for its excellence and already been shortlisted for three prestigious industry awards:Large Scale Project of the Year at the North West Energy Efficiency AwardsSustainability Project of the Year at the Aico HomeLink Community Awards 2022Best Retrofit Initiative at the Northern Housing AwardsOverall, an outstanding and successful refurbishment by our team that has given Buckley View in the North West a new lease of life.Ryan Robson at Rochdale Boroughwide Housing, said:“We are delighted and incredibly proud to have worked on the refurb project at Buckley View which has been recognised with three award nominations so far. These nominations are a testament to the great partnership approach by all involved parties, the highest levels of construction quality showcased throughout, and the exceptional performance outcomes of the entire project, for the housing residents, housing provider and for the wider area.”Technical Project DetailsThe external façade and sheathing boards on the existing, poorly insulated timber frame structures were removed. The sheathing boards were replaced with A1 rated carrier boards and the K Systems M, Mineral Wool Insulation System was specified.This system not only generates exceptional thermal performance and provides high levels of fire resistance (A2-s1, d0), but also boasts exceptional environmental qualities – by choosing it, we not only demonstrate our innate understanding of best-suited solutions but our dedication to sustainable working.The bespoke system specified for Buckley View was designed using 110mm non-combustible mineral wool insulation to meet the desired u-value of 0.20W/m2K, improved from 0.43W/m2K. This meant homes were more energy efficient, warmer, and less expensive to heat – a major bonus given the current cost of living crisis.For the finish, we specified a unique finish of VBriQ+ clay brick slips. This cost-effective, lightweight traditional clay brick slip system replicates traditional brick construction on low-rise buildings like the Buckley View bungalows.Our unique and innovative VBriQ+ clay brick slip finish was specified due to its robust, durable characteristics and wide range of colours. The brick slips were supplied in three colours, which totally transformed the facades aesthetically and with their low maintenance and element resistance qualities, will ensure the homes avoid cracking and maintain their appearance over time.At K Systems we are confident that we have the inspiring solution for every style, and this project is just one example of how we provide the flexibility to fulfil any specific design criteria.We tailored the specification process for the project based on the requirements of Rochdale Boroughwide Housing and their properties. Bespoke technical detailing included use of pistol brick slips around window reveals with a soldier course detail specified above window heads to create a contrasting aesthetic feature to the main walls. A band of silicone thincoat render was added as a design feature around the doors– yet again showcasing K Systems’ unrivalled attention to detail.

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.

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

London’s oldest station receives a significant upgrade to meet its increasing demands including optimum performance floor insulation

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

A unique residential Pocket Living development recently completed in Barking features highly effective thermal performance and an attractive appearance thanks to an integrated package of insulation and exterior façade products provided by Sto.

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

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

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.

“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. 

ChallengeTargeted with achieving a minimum BREEAM rating of Excellent and with only a short window of time to complete the project, Associated Architects, who designed the building, needed insulation products that would meet strict thermal and environmental requirements – as well as a manufacturer that could offer quick turnaround times and a high level of technical support.SolutionWith the help of Knauf Insulation specification manager, Marc Lawson, a through wall solution using 5,000m² of Knauf Insulation’s 100mm Rocksilk® RainScreen Slab – a rock mineral wool slab containing a water repellent additive, specifically designed for rainscreen cladding systems was used. It is quick and easy to install and is simple to cut and fit around brackets. The slabs knit together with no need to tape the joints – ensuring maximum acoustic and thermal performance, with no air gaps. Knauf Insulation’s Rocksilk® RainScreen Slab is also non-combustible and has the highest Euroclass A1 reaction to fire classification, as well as excellent sound absorption performance.To further enhance the thermal properties of the element, 10,500m² of Knauf Insulation’s Rocksilk® Flexible Slab 100mm, was installed in two layers within the SFS system. Designed to friction fit between metal studs, rafters and joists, Rocksilk® Flexible Slab is a multi-purpose rock mineral wool insulation slab, which provides excellent thermal and acoustic performance.Chris Kinman, Senior Design Manager at Willmott Dixon commented; “Knauf Insulation’s products are easy to handle and cut which makes them very easy to use on site. The first phase of the project has gone well, and the architect has adopted a similar approach to Phase 2 - which is testament to the excellent performance so far. Overall, we have been very impressed by the help and support we have received from Knauf Insulation on the project, and we have since recommended them to other colleagues."Rocksilk® RainScreen Slab and Rocksilk® Flexible Slab rock mineral wool products are made with ECOSE® Technology, a formaldehyde-free binder derived from rapidly renewable materials, instead of traditional petro-based chemicals used in other insulation. Additionally, ECOSE® Technology is up to 70% less energy intensive than traditional binders.

At the heart of Manadon Park, the site of the Royal Navy's former Engineering College, The Quarters is a development of 85 homes by Burrington Estates on the outskirts of Plymouth, in Devon. Although blending harmoniously, subtle differences have been introduced to each of the homes and 40 plots feature elevational treatments in Vandersanden’s Roxton and Corum multi-coloured bricks.Burrington Estates has established a reputation for building high-quality, design-led homes in the West Country. Completed in late 2020, The Quarters enjoys a peaceful ambience with mature trees creating a leafy vista. Energy efficiency is at the forefront of the scheme: the homes benefit from smart central heating, high-performance windows, excellent insulation levels and integrated PV panels to selected plots. Externally, The Quarters has a contemporary feel with classical elements. Stone detailing is incorporated within the red or buff brick elevations of some homes; others have creamy, rendered facades brought alive with features such as brick cills and brick arched window heads. Extended brick plinths further define the aesthetic.The scheme’s design was inherited by Burrington Estates at the planning stage, explains Steve Fowler, the company’s technical director. “The consented scheme included brick treatments to certain plots. In line with our core values as a business, we wanted a brick which was superior in finish to a run of the mill ‘standard’ brick typically used by more mainstream developers”.Vandersanden’s Roxton and Corum bricks are both stock facing bricks with sanded-coated and creased structures that are ideally suited to residential schemes. Roxton offers an attractive, orangey-red, multi-coloured aesthetic for an authentic, timeless look. The yellow buff base colour of Corum is augmented by shades of grey to create a varied, multi-coloured and high-quality textured appearance.“The Vandersanden bricks provided the perfect aesthetic and finish for the homes at The Quarters and were superior to alternatives on offer at the time of specification,” explains Steve Fowler. “The finished product looks good and works well with other elevation treatments used on the development.”To find out more about the bricks used in this project or to see the wide range of high-quality bricks available from Vandersanden, click on the 'View more' link

The finish to the asbestos roof and asbestos cladding on this property was faded and the roof leaked in several places, along with the gutter. Liquasil's silicone roof coating, Asbestoseal, was chosen to seal the roof and dramatically improve the aesthetic appearance using specially made RAL colours to the match the original finishes. The asbestos cement gutter was also lined with the Liquasil liquid gutter liner to form a permanent, bonded solution.

Salamander Street is a mid-market rent initiative that provides high quality affordable homes in the heart of Leith, Edinburgh. It comprises 199 flats and maisonettes across six storeys of accommodation, constructed over a basement car park.It was designed by 7N Architects, which specified Knauf Insulation’s 50mm Rocksilk® RainScreen Slab to insulate the ventilated façade. They chose this product because it met the brief’s two critical performance factors: thermal performance and fire safety.It is a Rock Mineral Wool insulation slab with a thermal conductivity of 0.034W/mK, so it delivers the required U-value of 0.16 W/m2K. It is non-combustible with the best possible Euroclass A1 reaction to fire classification and is BBA certified for use in a wide range of build-ups in high rise buildings. This means it complies with Building Regulations in Scotland that restrict the use of combustible materials on most buildings over 11m.The Salamander Street development was overseen by main contractor Cruden Building East with sub-contractor Soundtex responsible for installing the insulation.It was constructed using an Ancon Brick Restraint System. Ancon has undertaken independent third-party tests to demonstrate that its restraint system does not require a compression sleeve when used in conjunction with Rocksilk® RainScreen Slab under 180mm thick. This provided a huge saving in labour costs for Soundtex as fasteners are usually inserted into compression sleeves by hand.Throughout the build, Knauf Insulation’s Specification Team attended regular project meetings and conducted site visits to check the quality and progress of installation. Rocksilk® RainScreen Slab is optimised for ease of installation and improved robustness, making it easy to manoeuvre into position. At Salamander Street, the Specification Team noted the uniformity of installation and perfectly staggered joints. This is important because it ensures there are no gaps, which could reduce thermal and acoustic performance – a common issue with rigid foam board insulation.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.The Rocksilk® RainScreen Slab insulation was installed in conjunction with Knauf Windliner sheathing board for maximum performance.Thanks to Knauf Insulation, the residents of Salamander Street will enjoy warm, cosy homes that meet the highest standards of fire safety.

Failing factory finishes and cut edge corrosion were present across the entire roof and Liquasil's Metalseal metal roof coating system was specified as the most appropriate solution. The roof was cleaned and all failing finishes and rust was removed as far as reasonably practicable. The roof was then coated. In this case, two colours were employed. Liquasil is the only company able to produce silicone coatings in any RAL colour.

This asbestos cement roof in Norwich was soiled with moss and lichen covering the surface and had leaks in several places. Liquasil's BBA Approved Asbestoseal 20 asbestos roof coating was specified to extend the life of the roof and provide an aesthetically pleasing finish. The Contractor, ID Asbestos Ltd, carried out the works safely and efficiently.After being steam cleaned, the metal fixings were treated with our SWT Corrosion Primer and all fixings and cracks were sealer with Non-Sag Sealer. The whole roof was then coated with Asbestoseal 20 to provide a sleek new finish to the old asbestos sheets.Liquasil's Latent Defects Insurance Guarantee was provided upon completion.

Friesland Campina CHALLENGE An absolute must for refrigerated warehouses or dairy processing facilities is to try to keep the building as cool as possible and to avoid all causes of heat, in order to keep the cooling costs as low as possible. Some decisions can have detrimental effects though. Mechanical fixing of the roofing membrane for example, in case the wrong fastenings are used. Thermal bridging may cause cold – or in this case heat - penetrating through the flat roof fasteners resulting in higher energy bills. And, quite important as well, mechanical fixing will perforate the vapour control layer, which in the case of cool buildings sits uppermost on the insulation. The result being moisture-related damage to the insulation! Furthermore, it has also been proved that the darker the roofing membrane, the less the sunlight will be reflected, the more heat will be absorbed. Again resulting in escalating energy costs. Waterproofing a cool storage warehouse is definitely not easy! In this regard Friesland Campina were looking for a durable and ecological roof solution for their brand new refrigerated distribution centre in Maasdam. SOLUTION RENOLIT came up with the perfect answer: the RENOLIT ALKORBRIGHT cool roof membrane. Here’s why! RENOLIT ALKORBRIGHT is a completely white PVC membrane reflecting the sunlight up to 90%. Absolutely the highest solar reflectance rate ever. Thanks to this membrane, which prevents the interior from warming up, there will be no extra air conditioning expenses. In addition, an extra protective coating makes sure less dirt sticks to the roofing membrane. This layer will in turn help to maintain a durable reflection. 

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.

A stable conversion project needed an authentic clay roof finish.

The circular building, where legends like The Rolling Stones, Jimi Hendrix and Pink Floyd began, was redeveloped and reopened in 2006. FOAMGLAS® insulation was used for the floor, the façade and the flat roof, ensuring water and vapour resistance despite the open nature of the façade. It is also non-combustible and waterproof.

This is an asbestos cement roof coating and refurbishment project completed by Liquasil Approved Installers, Nadco Ltd. The roof was first cleaned and all cracks, small holes and fixings sealed with Liquasil Non-Sag Sealer, providing a permanent seal. The entire roof surface was then coated with the BBA Approved Asbestsoeal 20 asbestos roof coating system.

Scotland’s Largest Single Office Building with Rooftop Running Track and 360 Panorama.A Sustainable and Futureproof Roof, Harnessing the Power of the OutdoorsBothwell Street in Glasgow is now home to an exceptionally progressive office space – making way fora new chapter in the rich history of the area. If there are any doubts about what Grade A office spacereally means, then think touchless entry, bike storerooms, lux changing facilities, an 8,000 sq. ft roofterrace, a 150-metre rooftop running track, 4 activity zones/terrace spaces and panoramic views.The project complements the sustainable regeneration programme along the Clyde Waterfront also,home to the new financial Northern European hub, firmly cementing the business district at the heart ofmodern Glasgow.GOALSThe architects at Sheppard Robson have made sure sustainability and lifecycle credentials remaincentral to the design specification. Occupants’ wellbeing has been carefully considered with a stunningpanoramic rooftop and 150m running track and general outdoor employee wellness facilities.A roofing solution was required to support the lifecycle of the building along with an excellentproduct reputation for this distinguished office space. Given the quality, longevity and environmentalconsiderations required from the roofing design, the insulation properties and warranty performancewere extremely important from the outset.CHALLENGESOur Technical department assisted the architectural and construction teams to resolve numerouscomplex design elements across the varied roof zones including running track, ballast walkways, greenzones, and pedestal zones, to determine the best roofing solution.Installation of the Davit Arm System for a building of this scale was especially important so personnel canbe safely suspended whilst working at height. This presented us with a unique challenge in providing aworkable solution that aligned with the sequence of works, whilst facilitating future routine inspection ofits base plates, and maintaining waterproof integrity without compression.Careful planning and detailing were required around roof penetrations to minimise aesthetical impact,and roof equipment was safely installed above the roof assembly.SOLUTIONThe construction comprises a composite concrete slab receiving our Hot Melt Hydrotech Waterproofing System. Offering a true lifecycle – Hydrotech high performance waterproofing, through its’ unique characteristics and installation process, now forms part of the building fabric. The result offers complete watertightness for the lifetime of the building.The building is also insulated to a high u-value target offering exceptional thermal performance and achieving a high kPa rating. This was essential to receive loadings from all components including overlying finishes, roof equipment and the end use for the building occupants.Key fire performance standards were achieved throughout including the lift overrun and lower roof terrace areas where the preferred solution was switched to our Derbigum sustainable warm roof system to maintain project performance targets.LIFECYCLE MANAGEMENTDesigned with BREEAM credentials and an EPC rating coming in at below 10 the careful focus on lifecycleconsiderations and the choice of materials throughout the building envelope is exemplary.Hydrotech hot melt is a high-performance solution containing 30% recycled content and zero productfailures in over 50 years, offering lifetime peace of mind, designed for the service life of the roof.PROJECT DATACompletion: Autumn 2022Building Type: Commercial OfficeProduct Application: Hydrotech & Derbigum waterproofing systemsCertification: BBA Approved, European Technical Approval & FM Global Class 1Architect: Sheppard RobsonMain Contractor: HFD Group
