A series of 10 newly built affordable Council houses in Montrose, Scotland has been fitted with a high-performing variable-permeability vapour control layer from the A. Proctor Group. Procheck® Adapt is designed to protect the building fabric from the potential risks of condensation and act as an effective airtight barrier.The project, led by Angus Council comprises of a mix of one, two and threebedroom properties which will be built with energy efficiency in mind, providing residents with high-quality affordable homes which will be low-cost to heat and run.Jason Noble, Architect with Angus Council commented on the requirement for a high-performance solution to achieve the desired levels of vapour control and airtightness. “We required a high performing vapour barrier and air tightness layer, that could be installed on site by our contractor and achieve our performance specification. We wanted an effective vapour barrier and airtightness layer that when installed in accordance with the manufacturer’s recommendations and in combination with the timber kit construction would provide an effective airtightness rating of 4 when tested.”Contractor, Andrew Shepherd Construction proposed the use of the Procheck Adapt available from the A. Proctor Group, who has been serving the construction industry for 50 years with an extensive portfolio of technically advanced thermal, acoustic and membrane products.Thanks to its unique design, the Procheck Adapt membrane offers variable permeability which adapts to changes in humidity levels and allows the structure to dry out in the summer and in sunny days during spring and autumn while protecting it from moisture overload in the winter. This is possible because the membrane adapts its vapour resistance to the environment i.e., vapour tight in the winter and more vapour open in the summer.This ensures that the building fabric is protected from damaging moisture levels during cold, wet winter months, and allows the fabric to dry out effectively in warmer, drier months. The introduction of Procheck Adapt will ensure that it provides a high level of protection throughout the lifespan of the properties.Procheck Adapt has a translucent structure which eases fixing to structural frames and in combination with its integral tape allows for a fast installation time. Procheck Adapt is suitable for a variety of commercial and residential applications and provides airtightness to the structure as well as vapour control.

Forensic Science Ireland’s (FSI) new laboratory in Backweston campus, Co. Kildare, was designed by OPW.Their challenge was to build a durable, modern facility that was designed to meet the highest energy performance standards, with an effective wall assembly that helps protect laboratory staff from the elements.Partel worked with Duggan Brothers and Castle Ceilings to choose the most appropriate product system that would help achieve the Passive House standard for airtightness, considering the laboratory conditions.The forensic laboratory has been built incorporating a range of low carbon building solutions from Partel including the smart vapour control layer VARA PLUS, CONIZO and CONEXO MULTISEAL airtight tape, and also ACRAPRIME SPRAY.

As a company passionate about UK manufacturing, Aston Martin’s choice to work with Polyroof - the only independent UK manufacturer of cold-applied liquid systems - was a natural one.The new roofing system had to be cold-applied to eliminate the risk of accidental fire during installation. New insulation was also desirable to further improve the thermal performance of the roof. It was essential to reduce disruption to the operations of the facility, meaning any new system must be rapid to install with the existing roof predominantly being kept in place.After leaks were reported, The findings of Polyroof’s survey were presented to Aston Martin in the form of a bespoke specification, where the Protec Warm Roof System was the recommended solution. Core tests taken during the inspection had revealed that despite the leaking through the existing PVC single-ply membrane, the existing build-up of 60mm PIR insulation was found to be dry and in sound enough condition to be retained as the base for the new roofing system, saving the client time on the project.It was also identified that the current insulated roof configuration was missing a Vapour Control Layer, meaning the roof was at risk of condensation issues. This problem was designed out by the installation of 120mm Polyroof RES Insulation above the existing single-ply membrane, which was made good to form an effective vapour control layer.By creating a “hybrid” roof with double the insulation above the vapour barrier than below, the risk of condensation was eliminated and this was demonstrated by analysis conducted on the proposed build-up.To eliminate the standing water issues, sumps were placed around the existing outlets, greatly improving their drainage capacity, and offering a highly cost-effective solution when compared to the need to alter the falls of the roof.Polyroof Technical Services visited site regularly to advise and assist architects, specifiers and contractors in all aspects of the project.The finished roof provided a seamless and extra-tough waterproof membrane that was supported by the trusted Polyroof Accredited System Guarantee, with a separate insurance-backing scheme provided at no cost to the client. Aston Martin Lagonda now have the peace of mind that the roof above this landmark facility will be leak-free for decades to come.

Hexagon TowerBauderflex bituminous waterproofing system SynopsisHexagon Tower is a specialist science and technology facility located in North Manchester. The roofs of the laboratories were experiencing water ingress due to poor original detailing and aged interfaces. Whilst looking to replace the failing roof, the client also wanted to upgrade the insulation to increase the U-value and improve the appearance of the rooftop using a trusted system. Bauder was selected as the supplier due to its comprehensive service offering, which includes detailed report, bespoke specification, project advice and ongoing inspections to ensure a full system guarantee can be issued.Bauder Building BoardProject:Hexagon TowerLocation:ManchesterProject Type:RefurbishmentRoof Size:6,000m²Client:IF Building Consultancy Approved Contractor:BBR RoofingThe specificationWhilst looking to replace the failing roof, the client also wanted to upgrade the insulation to increase the U-value and improve the appearance of the rooftop using a trusted system.Project challengesThe building was occupied by employees during the works with multiple trades onsite. Bauder provided a system and installation methodology, to keep disruption to a minimum for both the employees within the building and the residents of the surrounding areas. The sensitive nature of the work being carried out within the building meant that mechanical and electrical equipment could not be switched off for more than a few hours at a time.The resultElements of the existing roof surface were removed, details modified and then a Bauderflex system incorporating vapour control layer, 120mm PIR FA-TE insulation and two-layer bitumen waterproofing, with a brown finish was installed.

Nestled in Ireland’s Hidden Heartlands, over-looking the Shannon Blueway and River Shannon, Drumhierny is a unique development of high-end holiday lodges situated in a 100 acre woodland estate. This multi-unit project, consists of sixteen lodges, in four distinct architectural styles, each nestled within their own private area of woodland. The lodges have been designed, manufactured, and constructed to achieve an A-rated Building Energy Rating (BER). To help achieve a thermally efficient building envelope a number of products from Partel have been used.The buildings were constructed using an offsite fabricated Light Gauge Steel (LGS) frame. As part of the frame construction a number of Partel’s low carbon building envelope solutions were used. This included EXOPERM MONO 150, a high performing breather membrane, IZOPERM PLUS, a phA Class Passive House Certified vapour control layer; and CONEXO MULTISEAL, a phA Class Passive House Certified airtight tape.

This project in Brixton required waterproofing on shop roofs and residential walkways, so a quick-curing system was a must to keep any disruption to a minimum for the business owners and residents.Specification – Systems UsedThe contractor was looking for a long-lasting and quick-curing system with an aesthetically pleasing and seamless finish – even on the most detailed areas.Therefore, we specified our OptiFlex-Rapid PMMA liquid waterproofing system to meet all of their requirements. OptiFlex-Rapid is our fastest curing liquid system with a typical curing time of just 20 minutes – ideal for projects with limited timescales. This system is cold-applied, reinforced with 150gsm matting and is suitable for year-round application.Build-up & Life ExpectancyThe build-up specified for this project consisted of our:Self-Adhesive PrimerSelf-Adhesive VCL (Vapour Control Layer)OptiFlex-Rapid Liquid Base Layer150gsm MattingOptiFlex-Rapid Liquid Top LayerOverall, the system is estimated to have a life expectancy in excess of 25 years.Challenges PresentedThe only challenge usually presented during an installation such as this would be the amount of roof detailing required. However, using a liquid system such as OptiFlex-Rapid made this process far easier, as it can be applied using a roller or brush for a durable and precise finish, particularly on detailed roofs.ResultsAs with all of our projects, our OptiTec Approved Contractors ensured a professional installation with fantastic results!

High-performance products from the A. Proctor Group, experts at solving condensation, airtightness and energy efficiency problems in buildings have been selected for use in the construction of a British Antarctic Survey building.The BAS Signy Cummins Hut is designed to provide a fully fabricated, fit for purpose hut, which can be easily erected to provide short-term accommodation for two British Antarctic Survey operatives to carry out incredibly valuable research in extreme polar conditions.Main Contractor, Mike Robinson of Rothwell Robinson, Manchester explained. “Due to the extreme conditions, we wanted to ensure that only the highest performing products were used on the project. In light of the extreme temperatures involved, we approached the A. Proctor Group who carried out a full condensation risk analysis.“Following the risk analysis, the recommendations adopted included Roofshield® for the roof and Procheck® 500 as a VCL for the walls.”“Another key factor was that the chosen components needed to be lightweight to be carried from the shore to their final location on the island.”Roofshield is an air and vapour permeable, highly water-resistant roofing underlay that has been made to the same high specification for over 20 years. The products reliable performance has been demonstrated in the toughest locations around the world. Its characteristics allow even very complex pitched roofs to breathe, without the need for air gaps or secondary venting.Many vapour and air permeable underlays use an airtight VP film layer to achieve their performance, whilst Roofshield’s patented SMS (Spunbond Meltblown Spunbond) structure allows high levels of airflow, in addition to the transport of moisture vapour, making the formation of condensation in the roof space virtually impossible. It has an extremely high degree of vapour permeability, as well as air permeability, so will still perform in conditions in which air tight alternatives will not.Procheck 500 is a strong reinforced polyethylene vapour control layer, for use within roof and wall constructions to prevent warm, moist air escaping from inside the building and condensing within the insulation. The woven extruded polypropylene multifilament scrim reinforcement provides exceptional tear resistance and robustness to withstand the toughest conditions.

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.

We all know warm roofs and joist zones are huge areas for air leakage and extremely hard to solve this problem. This warm roof structure for luxury apartments retrofit fit onto an already existing block of apartments in Tottenham was typically the icing on the cake for detail and performance. With the hand cut roof providing the client with multiple skylights, dormers and 360-degree turrets, this was going to be no easy task of getting the airtightness and vapour control secure and correct in a traditional method. Step forward Passive Purple! Rather than just covering the issues, once the hand cut roof was finished, the 220mm roof rafters were filled with a layer of spray insulation supplied by Lapolla UK. The dormers, skylights and turrets were then given some attention to detail with Passive Purple BRUSH before the final application of Passive Purple (spray applied) This gives this roof a complete airtight vapour control with performance like no other and getting around all of them circular details and angle’s galore this was just another simpler, easier way to get the job done right and guaranteed! Passive Purple liquid application saves the client and user so much time and so much less strenuous labour.

Another housing refurbishment is set to benefit from the high-performance Roofshield breather membrane. The world-renowned Roofshield membrane from the A. Proctor Group has long been recognised as a first-class roofing membrane solution, providing a pitched roof underlay that is air and vapour permeable.Specialist roofing company S & J Roofing in Bath has been providing roofing services since 1981 and has established a reputation for high-quality roofing work for all kinds of domestic and commercial works, from restoration to complete new re-roofs down to minor repairs.Naomi Richards of S & J Roofing commented, “we have used Roofshield on many of our projects, Roofshield will always be our number one go-to product. Using Roofshield leads to savings in both labour and material costs, keeping the installation team and customers happy. Roofshield was the most cost-effective solution to control the interstitial condensation in a pitched roof. Roofshield is the most reliable product on the market, so it is used on every one of our projects.”Roofshield is a unique, three-layer, nonwoven, spunbonded, polypropylene breather membrane with a patented melt-blown core, and it provides a secondary barrier to the ingress of rain, wind, and snow. Designed with a low vapour resistance, it is air-permeable, with the additional benefit that it eliminates the incidence of interstitial condensation in pitched roofs.The exceptional performance of Roofshield has been successfully incorporated in many of the most demanding locations worldwide. Its characteristics allow pitched roofs to breathe without needing air gaps or secondary venting. Its patented SMS (Spunbond Meltblown Spunbond) structure allows high levels of airflow and the transport of moisture vapour, making the formation of condensation in the roof space virtually impossible. Numerous vapour underlays use an airtight VP film layer to achieve their performance. However, the exceptionally high vapour permeability and air permeability of Roofshield means that it can perform in conditions in which air-tight alternatives will not.The exceptional air permeability performance of Roofshield means that the roof space will result in similar air changes to that of a roof using traditional eaves/ ridge ventilation. Therefore, another advantage of incorporating Roofshield into the roofing design is that it can lead to savings in labour and material costs due to removing the need for these vents as well as a separate VCL at ceiling level.

In the construction industry, contractors move at lightning speed to source the best products at the right price for their projects, all with the goal of ensuring client satisfaction and meeting tight deadlines. Renowned for our leading sealing, bonding, and insulation solutions, a selection of illbruck products were chosen through our extensive distribution network for the New Avenue project in Oakwood, London.The ProjectErected in an affluent neighbourhood within the London Borough of Enfield, New Avenue is an idyllic development boasting the peace and tranquillity of suburban life, whilst being only a stone’s throw from the hustle and bustle of Central London.Due to consist of over 400 mixed-type homes, ranging from apartments, maisonettes, as well as houses, this eight-year development will also include a community and energy centre, in addition to a new nursery. The SolutionDuring phase two of the new housing scheme, illbruck’s expertise were called upon to provide a vapour control layer for the Reinforced Concrete (RC) frame element of the project. This was to restrict warm, moist air from the interior of the finished structure from entering the fabric of the building. For the 11-storey block of flats, Central Essex Interiors required a solution at a competitive rate from a manufacturer with a good supply chain, due to the extensive size of the project.As a brand of CPG UK, illbruck has been recognised for over 70 years across the UK, Europe, and around the globe for supplying high performing solutions that meet the stringent requirements of the construction industry.

Basildon & Thurrock University HospitalBauder Total Roof System (BTRS) and LiquiTEC cold applied waterproofing systemSynopsisBasildon and Thurrock University Hospital’s existing roof was failing in multiple areas, and 80 rooflights needed replacing. The client wanted the refurbishment to make as little impact as possible on the departments directly below which included drug refrigeration, x-ray and ultrasound clinics, patient wards and operating theatres.Bauder Building BoardProject:Basildon & Thurrock University HospitalLocation:EssexProject Type:RefurbishmentRoof Area:900m²Specifier:NHSApproved Contractor:Breyer ConstructionProject challengesThe plant on the rooftop could not be turned off or raised and many of the AC units and boilers had to be left running due to the nature of the rooms below. Certain areas had to be repaired before others and detailing under and around the plant that could not be raised was almost an impossible task. When working around the plant, COSHH regulations had to be considered and adhered to.The result Coordinating with both the client and approved contractors was key in this project, and by using cold liquid applied waterproofing the contractors could ensure a watertight seal with quick application, allowing them to complete the remainder of the roof using reinforced bitumen membrane, and meet the tight project deadline of 12 weeks.System installedBauder Total Roof System (BTRS)Suitable for a variety of applications on both new build and refurbishment projects and can be used in warm, cold and inverted roof scenarios.1 Bauder K5KA top quality, heavy duty, torch-applied SBS elastomeric bitumen capping sheet.

For example, we provided a weekly plan for the areas we were working in and the rooflights / plant affected. Where possible, we worked out of hours while doing rooflight replacements to minimise any issues. We also worked closely with Bauder to vary the specification when we had to work around live plant. The communication between Bauder and Breyer Roofing was exemplary throughout and I was pleased this completed project was nominated for a national award."

Battle of Britain Memorial - The WingBauderThermofol PVC single ply waterproofing systemSynopsisThe client wanted the new visitor centre building to replicate the shape of the iconic spitfire wing and to be waterproofed with a roofing system that would be aesthetically pleasing due to its high visibility. A particularly challenging element of the installation was the amount of intricate detailing requirements due to the elliptical shape and 5⁰ pitch of the wing areas. The waterproofing system needed to incorporate insulation that would achieve a 0.16 U-value and the memorial site had to remain open throughout the works causing logistical challenges.Bauder Building BoardProject:Battle of Britain MemorialLocation:Capel-le-FerneRoof Area:700m²Specifier:Godden Allen LawnApproved Contractor:Byford Roofing ServicesThe specificationBauder’s anthracite coloured Thermofol single ply system was specified because it is high-quality, long lasting and with the addition of welded roof profiles gives the appearance of a standing seam metal roof.The result The system build-up included Bauder’s 160mm PIR Insulation for superior thermal performance and all deliveries were timed as not to conflict with vehicles moving in and out of the facility.

Fort DunlopBauder Total Green Roof System (BTGRS)SynopsisDuring the recent regeneration in and around Birmingham, innovation has been a key factor; a theme optimised by the redevelopment of the Dunlop Tyres warehouse which has been transformed into 45,000m² of office space and a 6,000m² hotel.Bauder Building BoardProject:Fort DunlopInvestor:Urban SplashLocation:BirminghamArea Size:7,100m2Architect:Shed KMContractor:James M Green Company LimitedThe specificationPractical challenges such as the reduction of noise pollution and maximising the building’s lifespan were all met by the Bauder Total Green Roof System with an extensive landscaping of sedum. The planting scheme provided instant coverage as the sedum was laid as pre-cultivated vegetation mats. Green roofs have excellent acoustic qualities for both external sound (up to 3dB) and internal noise (up to 8dB). This proved essentially in the selection of the Xero Flor blanket due to the proximity of Fort Dunlop to Birmingham Airport. The resultThe entire solution provided a watertight installation in conjunction with a 20-year guarantee whilst making the structure both environmentally friendly and aesthetically pleasing.System installedBauder Total Green Roof System (BTGRS) 1 BauderPLANT EA torch-applied, root resistant capping sheet.

MEDITE VENT and SMARTPLY AIRTIGHT proved to be a winning combination for the first oak frame Passivhaus to be built in the heart of Wiltshire, South West England.Built by award-winning construction company Erigo Developments, Seldom Seen, a private detached residence, was at the time of completion the first house in Wiltshire to meet the Passivhaus standard. It still ranks as only the eighth certified Passivhaus in the South West of England.Designed around a traditional oak frame and finished in oak cladding, the house was strategically sympathetic to its rural Area of Outstanding Natural Beauty (AONB) setting.The combination of MEDITE VENT and SMARTPLY AIRTIGHT helped to achieve its Passivhaus status.Rebecca Thursby, Director of Erigo Developments commented: “At the time, there was nothing else on the market that fulfilled its role in this location. We used an oak frame to create the external envelope and then choose both MEDITE VENT and SMARTPLY AIRTIGHT to achieve the level of airtightness required to meet the Passivhaus standard. We managed to get the air tightness down to 0.38 ACH @ 50 Pascals, which is very good.”To reach Passivhaus standard, a building must achieve an airtightness level of 0.6ACH (Air Change per Hour) at 50 Pascals or less. In other words, the volume of uncontrolled air leakages in 1 hour must be less than 0.6 times the overall building volume when the difference in air pressure between the indoors and outdoors is 50 Pascals. Named after French mathematician and physicist Blaise Pascal, ‘Pascals’ is the unit by which pressure is measured. In this case, it indicates the air pressure difference between inside the building and outside the building for the airtightness test. Reaching an airtightness level of 0.38 can be considered a remarkable achievement.Perfect for use in low energy buildings, MEDITE VENT is a high performance, breathable sheathing panel, suitable for use in timber frame structures. It boasts high racking strength in excess of Category 1 requirements, and high vapour permeability alongside weather resistance. Its extremely low vapour diffusion factor helps to prevent condensation and because it is manufactured with no added formaldehyde, it contributes to both a healthier working environment for installing contractors and a healthier living environment for building occupants.This intelligently formulated panel is teamed with SMARTPLY AIRTIGHT, an airtight structural OSB/3 panel with integrated vapour control properties, used as structural sheathing in timber frame buildings. These features eliminate the need for additional Air and Vapour Control layer (AVCL) membranes. Its coating also provides a durable, smooth surface perfect for the use of airtight tape at the panel joints. SMARTPLY’s in-house speciality surfacing technology provides this integrated vapour barrier, which delivers high and constant vapour resistance across the whole surface.For this project, the timber frame was in-filled with Icyenene sprayfoam insulation, with SMARTPLY AIRTIGHT lining the interior, alongside plasterboard facing the room. MEDITE VENT was installed on the exterior of the spray foam, which was then topped with Tyvek wrap and finished with the timber cladding.MEDITE SMARTPLY’s entire product range, including MEDITE VENT and SMARTPLY AIRTIGHT, is manufactured with FSC® certified Irish timber, from their own sustainably managed forests, demonstrating a clear supply chain and manufacturing process.Being conscious of how this industry impacts the environment is also something that Erigo Developments takes very seriously. Erigo is an award-winning construction company that puts an exceptionally strong focus on being environmentally responsible. The company demonstrates this by selecting carbon responsible materials and always aiming to achieve zero non-hazardous waste to landfill in all of their projects.“We've made a commitment that we're only going to build to a Passivhaus standard going forward, and to build with carbon responsible materials,” continued Rebecca. “I think everyone needs to do their bit to combat climate change.”“I think that building regulations need to go further in terms of power requirements and what's needed from houses now to achieve energy efficiency. That way, everyone knows what they can do in order to reduce their energy demands. There also needs to be more incentives in place to make people choose carbon responsible materials.”The use of MEDITE VENT and SMARTPLY AIRTIGHT provides a winning formula for sustainable building.

We have recently completed a 600m2 project in Westminster with installation by one of our main Approved Contractors, Ridgewell Flat Roofing.Specification – System UsedThis project called for extremely durable yet cost-effective waterproofing to be installed, which made the OptiTorch-Premium Bituminous Felt System the ideal choice. Having been used in the roofing industry for over 50 years, felt has been consistently developed and improved, and still remains one of the most popular systems available.OptiTorch-Premium bituminous felt is a high-performance waterproofing system that can be installed year-round, with excellent flexibility at temperatures as low as -25oC. This system provides long lasting resistance against UV rays and even contains special additives to protect against root growth.There was also a lot of detailing work and some gutter repairs required, so OptiFlex-Rapid PMMA Liquid was used for these parts of the project to ensure a completely watertight and visually appealing result.OptiFlex-Rapid is a quick-curing PMMA liquid waterproofing system with a typical curing time of just 20 minutes! It is cold-applied and is reinforced with 150gsm matting for extra resilience. OptiFlex-Rapid can be applied year-round and is a great choice for detailing and repair work as it can be applied directly onto most surfaces without the need for primer, which can often save time and money!The ProjectThis project was a 600m2 warm roof design with a standard build-up including 120mm tissue-faced PIR insulation, and also consisting of: OSA5 Primer, Vapour Control Layer, Insulation Adhesive, Insulation, Premium Self-Adhesive Underlay and Techno58 SBS Capsheet.Ben Ridgewell, owner of Ridgewell Flat Roofing, took on the project with Grant Jones (Co-Director) and his team, and completed the installation to their consistently high standards with an impeccable finish.The ResultsThe overall completed look of this project is very tidy and aesthetically pleasing – thanks to Ben and his team for a great installation, including an OptiTec warranty of 20 years to ensure peace of mind for the building owner for years to come.

When selecting your new polycarbonate rooflight, the main deciding factor should be how energy efficient you need or want it to be. In this process it is important to ascertain the rooflight’s U-value. U-values measure how effective a rooflight is as an insulator. The lower the U-value the more thermally efficient your polycarbonate rooflights will be.

Hethel Engineering CentreBauder Thermoplan FPO single ply system with Bauder solar PV systemSynopsisHethel Engineering Centre supports high performance engineering companies located throughout Norfolk. The original building at the centre had been operating at maximum capacity and they urgently required a new building to satisfy increasing levels of demand. The client wanted the new facility to meet a high level of sustainability, achieving a BREEAM excellent rating and using key renewable technologies, such as photovoltaics (PV) to minimise its environmental impact.Bauder Building BoardProject:Hethel Engineering CentreLocation:Hethel, NorfolkProject type:New buildRoof size:2,500m²Specifier:NPS GroupApproved contractor:Voland AsphalteThe specificationBauder’s Thermoplan single ply membrane was specified for the new building’s 2,500m2 roof due to its longevity.

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 roof on Bede Primary School and Community Centre in Gateshead was in great need of repair. Installing roofing contractors Hodgson and Allon liaised with IKO to refine the specification to meet the client’s requirements. This included a full strip and re-cover with a flame free system to carry a 20 year guarantee. IKO chose an IKO Mach One single layer bituminous system incorporating a site specific cut-to-fall system. This project was a complex roof replacement system with multi-trades required for specialist operations.

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.” 

Fulham JettyBauder Bakor 790-11 hot melt structural system with Bauderflex waterproofing system and BauderGREEN sedum systemSynopsisFulham Wharf is a landmark regeneration scheme that began in 2013 and included the ecological enhancement of an abandoned jetty on the River Thames. This redevelopment was designed to provide the local community with an ecological education centre and bio-diverse wildlife reserve.Bauder Building BoardProject:Fulham JettyLocation:LondonRoof Area:1,000m²Specifier:FabrikApproved Contractor:Accurate RoofingProject challenges One of the major challenges for this roof was installing the central sloped section, which required exceptional levels of technical input and workmanship. This roofing area was waterproofed with the same bituminous green roof system as the upper roof; however a special timber design for retaining the substrate and sedum blanket was also needed. Since its official opening in October 2013, the lower wildflower roof has become a haven for a variety of different birds and insects.The resultThe building’s new roof swoops down to become a continuum with the jetty deck and is covered with a green habitat providing three distinct environments for wildlife; one on the flat roof, one on the slope and the third on the jetty deck. The education centre roof was waterproofed with Bauder’s root resistant bitumen membrane before then having a sedum blanket fitted.
