"insulation"

Maidenhead was a cliché of uninspired and unremarkable buildings until Sainsbury’s embarked on a major redevelopment scheme. The supermarket now forms the base of a major new building, with five floors of car parking which are embraced by an outer layer of flats. Reynaers’ CW 50-SC glazing follows the building’s curve and works without clumsy capping on the outside. The flats were fitted with Reynaers’ CS 68 system which was chosen for its high performance and good insulation values. The project shows the flexibility of a varied architectural approach to which Reynaers products can provide robust solutions.

The next generation of CS 38 is now available from Reynaers – Slim Line 38 (SL 38) is a highly insulated inward and outward opening aluminium window and door system, that combines elegance and comfort with a unique design. The special slender steel look offers the perfect windows and doors for modern architecture and the renovation of steel-frames, respecting the original design but offering a thermally improved solution. Large-framed Crittall Windows complement the industrial aesthetic and gives the building a unique character and identity of its own. The fabricator on the project was AWS Turner Fain Ltd, part of AWS Group.

Burton Green Primary School is located in the historic city of York, an outstanding school at the heart of a local community this primary school strives for excellence. The challenging and nurturing learning environment allows children to learn and grow, while achieving the highest potential possible in all areas of the 21st century curriculum.When the roof began showing signs of ageing, it was clear that a long-term solution was required. Working with Project Managers Charles Garth and Principal Contractor Castle Special Projects, Polyroof would work towards providing the best solution to refurbish the ageing roof.The work required and condition of the roof needed to be established first, to do this a survey was scheduled to take place. The survey was conducted on roofing area and it was determined that there were 6 flat roofs that required refurbishment. Areas 1 to 2 were constructed of a built up felt with mineral cap sheet, 50mm PUR insulation, bituminous vapour control, asphalt, 12mm fibreboard and a 50mm woodwood slab deck with timber joists. Areas 3 to 5 were constructed of a built up felt with mineral cap sheet, 50mm Jablite insulation, bituminous vapour control, asphalt, 12mm fibreboard and a 50mm wood wool slab deck with timber joists. Roof area 6 was made up of built-up felt with mineral cap, plywood and timber joist. The original build-up of roofs 1 to 5 needed to be stripped back to the asphalt due to the aged condition of the built-up felt, numerous leak reports were reported. Roof 6 and its original waterproofing was to be retained and made good, later this surface would act as the substrate for the new waterproofing system.Once the survey was completed, a bespoke specification was written and it was recommended that the roofing areas would all benefit from a high-performance waterproofing system. In addition to this it was specified that the roof would be thermally upgraded to reduce the risk of condensation and provide lower fuel bills and energy consumption for Primary School further adding benefits to making improvements to the roof.Liquid Roofing Limited an experienced roofing contractor and Polyroof Approved Contractor was chosen to undertake the work to this project. The proposed system for this project would be Polyroof Protec Warm Roof System. Protec’s liquid roof membrane has a unique flexible hybrid polymer formulation and can be applied to virtually all common roof surfaces.The areas that were required for installation firstly needed to be stripped and removed back to the asphalt, areas 1 to 5 required this. Area 6 was then repaired of any defects and made good where necessary. All roofs required a deep clean, removing any dirt or debris that remained from the first stage. Once this preparation was completed an Air & Vapour Control Layer (AVCL) was then installed to roof areas 1 to 5 making sure that all surfaces are smooth and without voids.Using a Polyroof Twin Pack Insulation Adhesive the Polyroof RES insulation (T&G) boards were bonded and laid to each of the 6 roof areas completing the second stage of the warm roof upgrade. Before the last stage of the installation could begin all joints in the insulation were sealed using taping matt and Polyroof Protec Resin. Polyroof’s extra-tough GRP trims were then installed to create neat and robust edge detailing for exposed perimeters before the main Protec system application commenced.During the project there were some challenging aspects that required care and attention. The project featured a large array of different details ranging from installation of new substrates and trims for parapet walls to the removal of and preservation of tiles/cladding so that the Protec system could be applied correctly. These features required delicate work so that the original tiles/cladding could be reinstated after the application of the system was completed. During the project the rooflight that was originally in place was removed and replaced with a new, before this could happen the Protec system was taken up the upstands and then sealed under flange.Once the project was completed within the relevant time frame of the client and within the budget specified, the Polyroof Technical Services team conducted a detailed inspection showing a high level of workmanship which lead to the client gaining the trusted Polyroof Accredited System Guarantee.

The project consisted of two similar flat roof areas totalling 1,100m2 above high-rise residential blocks in a city centre location. The existing roofs were an inverted roof design that had been waterproofed with single-ply that had failed prematurely. Numerous short-term, localised repairs had failed to stop the water ingress and leaks had been a long-term problem.It would have been impractical to remove the tons and tons of ballast and insulation from the top of the high-rise building and it was imperative to the client that removal or replacement works were not involved at all. The specific nature of this project required careful consideration, and so a survey of the roof was arranged.The SolutionA report from an independent consultant commissioned by the client identified a problematic challenge with an overlay option. The existing falls of the roof were assessed to be poor, and so standing water would be an issue for any new waterproof covering. The report concluded that this would reduce the lifespan of an overlay waterproofing system and so was advised against. The client initially thought this to be a stumbling block and that costly and impractical modifications to the roof would need to be made.Having worked with Polyroof on scores of other projects, the client turned to Polyroof Technical Services for a solution that could meet their stringent criteria. Following on from the preliminary discussions, Polyroof’s Technical Services assessed the site, taking core samples and then providing a suitable specification to overlay the roof with the Protec System.The BBA certification of the Protec system specifically covers use for zero falls (completely flat) applications, meaning the client had absolute peace of mind that standing water would not be a detriment to the integrity of the waterproofing system. The client was able to achieve the original objective of an overlay system and benefited from the associated cost and time savings. Furthermore, the BBA certificate states that when used in inverted roof scenarios the lifespan of the Protec system is as long as the design life of the roof.Work was started with J R Flat Roofing, a Polyroof approved contractor with national coverage, moving the ballast and insulation to one-side in four phases of 140m2 at a time, exposing the single-ply membrane to which the Protec system was directly applied.Due to Protec’s rapid cure and walk-on times (30-60 mins dependent on conditions), the system is ideal for larger, phased refurbishment, as specific sections of the roof can be made waterproof with the full Protec system in one day. When carrying out the next section, the new Protec membrane forms a totally seamless and watertight joint to the existing Protec-covered areas.Another objective was to reuse the original inverted insulation and ballast pebbles as this was cost saving and negated the need for the lifting logistics that would have been involved in bringing the ballast to ground level. Additionally, it made the process as environmentally compliant as possible by keeping waste to a minimum. The insulation and pebbles were re-applied in its original format and, due to the weight of the pebbles, was a mammoth task that required three miniveyors to help with the handling. A series of special aluminium breather vents were also fitted down to the concrete slab roof substrate to enable the surface to dry out over a period of 12 months.The whole job was completed in three weeks and the client was delighted with the finished work. With a 20-year insurance back-guarantee and a maintenance-free waterproof membrane that will last as long as the roof stands, the client was once again left with total peace of mind that their buildings could not be better protected.

Comprising of nine shops and several residential flats, properties 29-47 High Street Polegate required a full roof refurbishment after complaints of water ingress into the residential buildings. Proteus Waterproofing conducted a thorough survey which revealed that the existing roof build up, made up of a timber deck and 2-layer felt, had been previously repaired but was now at the end of its serviceable life.Being a residential building with a combustible deck, protecting individual properties from internal fire spread was a key consideration. Compartment walls were identified allowing Proteus Waterproofing to provide a solution that would meet regulatory guidance relating to the junction of compartment walls and roofs in Approved Document B whilst meeting the needs of the client.Proteus Waterproofing specified their robust reinforced bitumen membrane range of Proteus Pro-Felt®, including a bespoke hybrid insulation approach, where instead of a full replacement consisting of entirely non-combustible insulation, a scheme was designed to meet the requirements above and either side of the compartment walls, offering the client the most cost-effective solution possible that would also mitigate any unnecessary increase of weight loading elsewhere on the roof.High Performance WaterproofingThe waterproofing and existing deck were stripped back and re- decked with 18mm plywood. When removing the existing waterproofing, our approved contractor, carefully recorded the exact location of the party walls as no drawings of the upper story flats were available.Proteus Pro-Felt® SA AVCL was used as a vapour control layer to allow for the application of the hybrid combination of 150mm Proteus Pro-Therm PIR insulation and 150mm Proteus Pro-Therm Mineral Wool insulation. A thermal calculation was undertaken to ensure that the final result met the requirements of Part L of the National Building Regulations. These were both adhered with Proteus Pro-Bond Foaming Adhesive. Proteus Pro-Felt® SA Underlay Plain was laid and finished with Proteus Pro-Felt® Ultima Plus Fireguard Mineral Capsheet, providing the client with a fully waterproofed Part B and Part L compliant roof, guaranteed for 20 years.Proteus Waterproofing worked closely with the Proteus Approved Contractor, to ensure the project was delivered to a high standard.Health & SafetyWhen working on occupied buildings, safety is always of utmost importance, as well as keeping disruptions to a minimum. The Proteus Pro-Felt® range have been tested to the highest European Classification of BROOF(t4), making it the ideal system to use on all buildings, as the risks to residents, property and members of the public are greatly reduced. All Proteus Waterproofing specifications promote fire safe installation methods conforming to the industry lead Safe2Torch guidelines. Proteus also have a range of cold liquid applied membranes which are also BROOF(t4) certified.Long Term PerformanceProteus Pro-Felt® offers high-performance bituminous membrane systems, tested to perform in extreme temperatures and weather conditions, while offering clients a robust and cost-effective waterproofing solution. Proteus Pro-Felt® Ultima Plus range retains its high polymer performance. Its class leading, high quality modified bitumen content allows this flexible membrane to move with the building and ensure long term durability and performance with third party BBA accreditation and guarantees available up to 30 years.

As part of its ongoing work to improve the energy efficiency of its homes, over the last two years Clarion Housing Group has retrofitted 505 homes across Fenland, Tonbridge and Malling which had an Energy Performance Certificate (EPC) rating of D or below. Among them were 13 bungalows in the Chapel Gardens development in Benwick. The work was part-financed via the first wave of the government’s Social Housing Decarbonisation Fund (SHDF), which was launched in 2021 to help social housing providers and local authorities increase the EPC rating of their properties to C or above. All social housing provided by registered providers was eligible for SHDF wave one funding, regardless of archetype, and the work being carried out is designed to tackle issues associated with fuel poverty including mould and condensation.    As a registered provider of social housing, Clarion could apply for the funding as part of a consortium with Fenland District Council and Tonbridge & Malling Borough Council. The £4.35m secured by the two local authorities was match funded by Clarion, which is working closely with its main contractor Equans to upgrade the homes. “We were already carrying out works to improve residents’ homes under existing maintenance contracts, in line with the government’s 2030 EPC C target, but this funding has allowed us to accelerate and increase the scale of it all, ultimately improving more homes much faster,” said Daniel Archard, asset sustainability manager at Clarion. Meeting PAS 2035 standards  Sarsvati Varsani is part of Equans’ dedicated specialist retrofit team. As a senior technical retrofit advisor for the contractor, she is overseeing the process in terms of energy efficiency and compliance. She said: “The delivery of all SHDF projects must be PAS 2035 compliant, which specifies a whole-house or whole-building approach to retrofit. It means that energy efficiency measures should be installed with the requirement of the entire building in mind – both from a technical standpoint and considering factors like occupant comfort. “The SHDF facilitates a multi-measure approach to allow us to upgrade Clarion’s least energy-efficient homes to meet the PAS 2035 specification using more than one measure. For example, as well as replacing insulation we are also installing air source heat pumps at the properties where necessary. “I’m working closely with the site team, retrofit designer and contracts manager to address any issues throughout and ensure that every measure is compliant with the standard. Representatives from Clarion and the Department for Energy Security & Net Zero also conduct site visits to review progress throughout.” One of the key principles of wave one of the SHDF is a fabric-first approach. This ensures heat loss prevention measures are installed before other energy efficiency measures, to maximise the dwelling’s suitability for low carbon heating either now or in the future, and to benefit tenants in terms of comfort, health, well-being and bills. The Chapel Gardens bungalows had an original U-value of 1.43W/m²Km, so this was going to take considerable changes. Having been built between 1967 and 1975, the cavity insulation in the bungalows was no longer fit for purpose as it had slumped to the bottom or – in some cases – didn’t even exist. It has now been replaced with a polystyrene bead insulation. The benefits of external wall insulation As part of the fabric-first approach being taken by Equans and Clarion, Saint-Gobain Weber’s External Wall Insulation (EWI) system was specified for the bungalows to improve their thermal efficiency. It is being installed by FRT Property Services Ltd, which is PAS 2030:2019 certified – something that is required of all of the subcontractors working on this project. By gaining PAS 2030:2019 certification, retrofit installers can demonstrate that they have installed energy efficiency measures that meet the required specifications, and have delivered on customer requirements and expectations in accordance with TrustMark standards. FRT Property Services – which began working on Chapel Gardens in January 2023 – specialises in EWI and its director Farhat Ahmed and Operations Director Radu Ursache helped to ensure work was delivered to Weber standards, on time and within budget.  For this project, Farhat’s team installed webertherm XM with 100mm of webertherm MFD insulation. The SHDF stipulates an energy performance outcome of 90kWh/m2/year, with a target U-value of 0.30 W/m²K. The addition of EWI from Weber was critical in enabling Clarion to meet the SHDF space heating demand performance outcome, as the replacement cavity wall insulation alone wouldn’t suffice – with the properties only achieving 0.44W/m²K. Having requested that the retrofit work didn’t change the aesthetic of the bungalows, the planners wanted to maintain a brick finish. To achieve this, weberwall brick was specified along with the webertherm XM EWI system. This innovative brick slip system is lightweight and quick to install, containing the equivalent of 20 brick faces per sheet. It is available in a wide range of colours including Antique Buff, which meant it was possible to closely match the surrounding buildings.  Farhat said: “The team at Weber has been very helpful throughout the process and applications manager Linda Twidale showed my team how to install the product. It’s very simple and provided the like-for-like result the client wanted; as far as brick slip systems go, weberwall brick provides the closest match to real bricks I’ve seen while working in this sector.” It was important to Clarion that the residents of the bungalows were able to remain in their homes while the work was completed which is why EWI was the perfect solution. Farhat’s team worked closely with Equans’ retrofit liaison officers and other subcontractors, including the scaffolding and utilities companies, to ensure everything went smoothly and the homeowners were not inconvenienced.  By installing the webertherm XM EWI system, the U-value at the properties has been improved to an efficient 0.20 W/m²K – far exceeding the target of 0.30W/m²K. Once all of the retrofit work has been completed, the bungalows will undergo a post-works EPC assessment and are expected to achieve a C rating. The new insulation will provide improved thermal performance all year round, helping to keep residents’ homes cooler throughout the summer and warmer in the winter. It is predicted that those living in upgraded Clarion properties will save between £300 and £500 on their energy bills each year. Switchee smart thermostats have been installed in some properties to relay data to Clarion, enabling them to monitor the energy consumption of the properties. Within six months, Equans’ retrofit evaluator will issue a questionnaire to residents to assess whether everything works as it’s supposed to, and Farhat’s team has already received feedback. He said: “Residents have told us they’re already feeling the difference in the temperature of their home. “It isn’t right that people have had to choose between eating and heating but getting such positive feedback really highlights the role that we’re playing in improving these homes.” Daniel Archard, asset sustainability manager at Clarion, added: “We’ve received more funding via wave two of the SHDF and are planning to increase our retrofitting tenfold over the next three years, as pressure builds to upgrade all social housing to an EPC rating of C or above by 2030.” Farhat concluded: “We’re looking forward to continuing our support during the delivery of the future pipeline of work within this area for Clarion Housing under SHDF Wave 2.1.”

Fire resistant, multi-directional, high movement, structural joint sealing of floor slabs from below for 120minutes, EI Fire ratings using Emshield-DFR from NCC Movement joints Limited.St William is a division of Berkely Homes, predominantly working on some of the most technically complex regeneration projects on brownfield sites, at the heart of communities across London, and typically with a landscape-led approach. Riverside Park and Gardens is being developed on the former Leven Road Gasworks in Poplar, East London, forming part of the 20 acres Aberfeldy Village scheme. This is an ambitious regeneration project in the borough of Tower Hamlets, with around 3000 new homes, plus shops, offices, cafes, bars, and a cinema, as well as extensive landscaped gardens, play areas, and riverside walks.On this important development by the River Thames, the structural floor slab joints ranged from only 15mm to 25mm wide, but they were subject to high multi-directional movement requirements, plus they required a minimum 120-minute EI Fire Rating to protect the future residents. To add to the complexity, there were shear connectors within the floor slabs that also needed protection to ensure their structural integrity in the event of a fire.An “E120” denotes that the system will not allow flames and hot gases from physically passing through the element for 120 minutes, which also explicitly denotes that the system will achieve 120 minutes ‘Integrity’ (E) and ‘Insulation (I), known as EI120, which therefore also achieves 120 minutes ‘Stability’ (R) in fire.Emshield-DFR-2 provided the ideal solution, and one which could also be rapidly installed from below in a single operation. This specialist work was completed by specialist fireproofing contractors, Gould Sealants Limited, working for Main Contractor, Morris Roe.

Metrotile Lightweight Roofing’s classic ‘Roman’ profile adorns the rooftops of a five building renovation ‘pilot’ project at Davis Road, DoncasterEach of the buildings is a prefabricated Hawksley Bungalow and has been modified throughout the yearsTo bring the homes up to ‘Decent Home’ standards, two major changes were made to the building’s exteriors. The first was a brick ‘skin wall’, that was built around the metal walls of the homes (adding a layer of insulation in the process). The other major alteration was that of a new roof in the form of a Metrotile lightweight tile system providing swift installation, traditional aesthetics and a low weight to reduce the load on the Hawksley Bungalow’s structure.

Delivered at a cost of £46.5 Million the scheme comprises four 6-17 storey accommodation blocks housing 864 student units. Acoustic performance was key for the glazing in noisy roadside areas and lower levels. The solution was Senior’s energy efficient SPW600e windows fitted with acoustic energy efficient insulated glass units to achieve a sound reduction index (RW) rating of 43.   A light and welcoming space, was created in communal spaces using Senior’s thermally enhanced SF52 fully capped two-storey aluminium curtain walling, whilst perimeter capped silicone glazed SF52 was chosen for the link bridge between accommodation blocks. 

Coláiste an Chláirín Bauder Thermofol single ply waterproofing system with BauderROCK insulationSynopsisThe new Coláiste an Chláirín building in Athenry, Co Galway is a post primary school consisting of classrooms, a special needs unit, sports hall, general-purpose hall, staff amenities and extensive external facilities designed by Smith Kennedy Architects & Healy Partners Architects. The project was managed by JJ Rhatigan and Company and the roofing element appointed to Priority Roofing and Cladding Ltd. The roof of the main building and the gymnasium required flat roof build-ups to meet the specifications as set out in in SDG 02-05-03 (Acoustic Performance in New Primary & Post Primary School Buildings), while meeting the general performance requirements specified within TGD 021-7 2018 (Minimum Performance Standards of Roof Materials and Finishes). The chosen system had to meet an acoustic performance of 35dB indoor ambient noise level (IANL). It was decided that, despite sports halls having a slightly higher IANL threshold, the 35dB performance criteria would be applied across all areas of the school, with control of reverberation being a key consideration in the gym.Bauder Building BoardProject:Coláiste an ChláirínLocation:County GalwayProject type:New BuildRoof size:8550m²Main contractor:JJ Rhatigan & CompanyApproved contractor:Priority Roofing & Cladding LtdThe specification:The Architect specified that the insulation used in the flat roof system should be non-combustible and achieve a U-value of 0.16Wm²k which actually exceeds the thermal requirements as described in the Irish Building Regulations Technical Guidance Document L for flat roofs in schools.BauderROCK was specified to achieve the thermal and acoustic requirements of the design. As a Euroclass A2-s1,d0 non-combustible material, BauderROCK also provided the specified fire performance. This insulation could be used across all roof areas, with some adaptations for the gym which required additional acoustic performance due to the inherent nature of the space. Acoustic infills were used in the troughs of the perforated metal deck, thus combatting the reverberation of the indoor environment.  Products appliedBauder Thermofol PVCAn integrated single ply waterproofing system, featuring a lightweight, cost effective membrane which offers a pleasing aesthetic finish on a flat roof. This system holds fire classification BROOF(t4) for compliance with building regulations under TS 1187 test method 4 for external fire exposure to roofs. BauderROCKHigh density mineral wool insulation.Project challengesOne of the challenges of this project was the ambitious schedule. The use of the self-adhesive air and vapour control layer (AVCL) enabled the trades working within the building to progress quickly without being delayed by weather conditions. BauderROCK is relatively quick to install, as was the lightweight single ply waterproofing.  The resultThe project was finished to time and specification with exceptional workmanship from the fixers at Priority Roofing and Cladding and superb collaboration from all parties throughout. The membrane was finished with standing seams to create a statement look. The roof achieved a U-value of 0.15 W/m2k, exceeding the thermal target, and met or exceeded the 35db IANL requirement across the main building and the sports hall.  The thermal performance, which will hold up for decades to come, will also impart energy efficiency benefits that reduce running costs at the school in the long term. Finally, the non-combustible nature of the mineral wool insulation ensured that the build-up met the fire safety specification. System installed Bauder Thermofol PVC single ply waterproofing system1 Bauder THERMOFOL U15 V FRThis 1.5mm polyester reinforced Poly Vinyl Chloride membrane (PVC) membrane benefits from being highly flexible due to the incorporation of internal plasticizers during the manufacturing process. The combination of materials within this membrane provides high tensile strength, with thermal stability and chemical resistance.2 BauderROCKA mineral fibre non-combustible insulation with high acoustic performance. The dual density mineral wool composition delivers compressive strength, whilst keeping the overall weight to a minimum and providing high noise absorption which enabled the complete system to meet project requirements.3 BauderTEC DBR 06This 0.6mm, self-adhesive, elastomeric air and vapour control layer is light weight and benefits from cleaner, safer, and faster installation than traditional torch applied membranes. Advocacy Niall Hanley, Contracts Manager at JJ Rhatigan, the project’s main contractor, said:"Coláiste an Chláirín Athnery was a great success and in particular the use of the self-adhesive AVCL in advance of the build-up allowed works to commence immediately internally, which was critical from a programme perspective.” Kevin Ryan, Director at Priority Roofing, explained:"We found the system both practical and efficient to install. The combination of the availability of the products and the technical backup received was superior to any other system that we have worked with.”  Eoin O’Grady, Associate Director at Healy Partners Architects commented:"We are delighted with the overall delivery of the roof build-up and the performance achieved. The PE hall solution to deal with reverberation noise as well as rainfall noise was very successfully managed. We look forward to working with Bauder on future projects.” 

This project was one of the largest schemes of its kind ever achieved outside of the capital, featuring the Aquamodul warm blue roof with our Force Dalle BBA approved system.Systems in useWilotekt®-PlusForce Dalle®Aquamodul®Extensive Living RoofChallengesThe roof attenuation rate required was 7litres/sec across the 6500m2, which is extremely low for such a large area, and the u-value of 0.10W/m2K was relatively demanding in terms of thermal performance. It was a project specific requirement that the roof was designed with falls within the slab in order to avoid any ponding water.SolutionsThe design and implementation of a site wide blue roof ensured the development’s contribution to mitigating flood risk in the UK, supporting the protection of England’s waterways. Modelled over a 300 year period, the blue roof design is future proofed in terms of its provision for likely climate change and increases in predicted peak rainfall events.Wilotekt-Plus, second generation hot melt structural waterproofing system, was installed as the Air and Vapour Control Layer (AVCL), which provided an extremely robust waterproof structure during the external envelope and superstructure construction phase. Hytherm ADH thermal insulation and Force Dalle bitumen membrane with anti-root technology were later installed to complete the waterproofing and insulation system.Upon final QA inspection and integrity testing of the roof waterproofing works, the Aquamodul blue roof system, bespoke Hydrosoil Wildflower living roof and standard ballast finishes were installed in conjunction with a Solar PV array, which generated the majority of the building’s electrical energy requirements.

Broughton & Yeamans House are high rise apartment blocks in Bristol, Avon, under the management of Bristol City Council. The roof areas, totalling over 3,500m2, had originally been waterproofed with asphalt and then later treated with a coating repair.Unfortunately, water ingress continued to be a problem with leaking occurring at numerous locations. Not wanting to cause further disruption to the residents and to avoid costly damage to the interior of the buildings, the council contacted Polyroof and a survey of the roof was arranged.The survey by Polyroof’s Technical Services highlighted the extent of the issues within the roof, including identifying water ingress through the many vertical sections present on the roofs, including parapet walls and the lift house building. After performing core tests on the roof, it was shown that the existing roof build, which contained insulation as part of a warm roof design, was in a suitable condition to be retained and overlaid – avoiding costly disruption for the client and residents.A bespoke specification was drawn up by the Polyroof Technical Team that provided a comprehensive set of recommendations to ensure the apartment blocks were fully protected from the elements.To make sure the roof could be left in a totally weatherproof condition, it was necessary to treat not only the flat roof sections but the vertical areas too. The client was keen to improve the thermal performance of the buildings by adding additional insulation, but it was imperative that disruption was kept to a minimum – not only would stripping works impact on the buildings’ residents, but hauling waste materials from such a great height would be costly and logistically challenging.With BBA approval, top-rated fire performance and Polyroof’s trusted 20 Year Accredited System Guarantee, the client has total peace of mind that the apartment block could not be better protected for decades to come.

St Benedict's School in Ealing, West London holds the distinction of being the only the third Passivhaus certified school in the UK. We were naturally delighted to be part of the construction team for such an exciting project. Architects van Heyningen and Haward were commissioned to design two new Passivhaus buildings for the independent Catholic school - a sixth form centre and a primary building. We were appointed to design, manufacture and install 78 Passivhaus-certified aluminium clad windows, with a Uw rating of just 0.79. We also provided thermally-efficient timber aluminium curtain walling, plus Reynaers CS 86-Hi high-insulation aluminium doors.

ACE solution for the decoupling of production machines ensures calm in chocolate production by reducing low-frequency vibrations to a minimumAt a renowned Belgian chocolatier, part of the production process led to vibration and oscillation in an adjacent house. Despite numerous tests, the manufacturer was unable to find a solution that could isolate vibrations below 20 Hz, until they came across ACE products. The PLM pneumatic levelling elements from the ACEolator range from ACE offer significant insulation from a frequency of 5 Hz and up. Now 14 PLM-3’s installed in the facility are reducing vibrations by 80 percent. Any remaining vibration can only be detected with measuring devices.

Middlewood Locks is a £1 billion, 25-acre regeneration project located in Salford, Greater Manchester. This unique urban development is surrounded by three canal basins and the River Irwell for relaxing and peaceful walks.The new homes will feature full-height glazing, high-specification interiors and private outdoor space overlooking the city and waterways.Key necessities was to install non-combustible insulation with a low U-value performance on the external façade to provide fire resilience and thermal performance for future residents.To aid in this the construction team opted for ROCKWOOL RainScreen Duo Slab®. It was chosen due to it's Euroclass A1 non-combustibility classification and its proven thermal and acoustic qualities.

Rochdale Upperbanks is a regeneration project, this development brings new life to a formerly disused brownfield site. The Upperbanks scheme comprises 242 studio, onebed and two-bed apartments, all with balconies, housed in two nine-storey apartment blocks and a 146-room Hampton by Hilton Hotel.With the notion to help build comfortable living spaces and the challenge of noise pollution, it was important to find a solution to these needs. With the help of Willmott Dixon acting as the main contractors, ROCKWOOL products installed included RWA45 and Soffit Slabs which both carry a Euroclass A1 classification.More than 5,000 square metres of ROCKWOOL insulation was specified by the architects for the whole façade system.
