Aston Martin Headquarters

Aston Martin Headquarters

Polyroof Products Ltd

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.

Protecting the Fabric of the Building: New Avenue Case Study

Protecting the Fabric of the Building: New Avenue Case Study

illbruck – a brand of Tremco CPG UK Ltd

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. Catering to a wide range of installation environments for both interiors and exteriors, from major building schemes to home improvements, our solutions can be tailormade to you or your client’s specification.The ApplicationProcured through one of our distribution partners, AC Fixings Ltd, illbruck ME003 Vapour Barrier was stapled into the party walls of the construction to achieve adequate vapour control. 500 rolls of this innovative 3-ply solution were required to protect the fabric of the building and its insulation, by providing a vapour and airtight seal. This in effect will help to improve the overall energy efficiency of the New Avenue apartment block, due to the product’s high-grade granules, which means that the SD value (resistance to vapour diffusion) is not lowered. The flexible and tear-resistant nature of this product boasts ease of application due to its lightweight properties, and is compatible with a number of illbruck’s intelligent window membranes and adhesives.Following the installation of ME003, illbruck’s ME315 Total Protection Tape was used to provide a high performance air and weather tight seal. This special tape is suitable for a wide variety of applications, and achieves a permanent bond to all illbruck indoor and outdoor building protection membranes. This fully compatible solution is highly UV and moisture resistant, quick and easy to install, and can be used within partially open facades. ME315 is also certified to EMICODE EC1 due to its low emission production, contributing to the energy efficient properties of ME003 to provide a total green solution for New Avenue.Scott Hurry, Area Sales Manager for illbruck, commented: “It has been a pleasure to work with our valued customer, AC Fixings, who in turn have supplied Central Essex Interiors with two of our leading products from our sealing and vapour control range.“illbruck was chosen due to being a highly recognised name within the marketplace, and we have been able to work with the Client to supply the products at a competitive rate and turn the project around quickly.

Grand Designs: Green Roof Project

Grand Designs: Green Roof Project

Polyroof Products Ltd

The Protec System was used to waterproof the domed green roof areas of this striking, sustainable house development which was featured on Chanel 4’s Grand Designs. With an ambitious vision and a tight budget, Robert and Milla Gaukroger set about transforming a dated 1980’s house overlooking Lake Windermere into a state-of-the-art, eco-conscious home. Since the house lay in beautiful hillside surroundings, in order to blend into this setting, the domed roofs of the house were to be covered with a wildflower meadow mix to provide a green roof construction.The SolutionThe Protec System was chosen as a waterproofing membrane for the roofs as it is ideally suited for green roof applications. Lightweight, flexible and highly durable, the system can easily accommodate structural expansion movements and is tough enough to resist root penetration. The Protec system was applied to over 350m2 of domed roof to provide a long-lasting waterproofing membrane.The key reasons why Eastleigh chose Protec are the same reasons that has seen it become one of the fastest growing cold-applied liquid roofing systems in both the new build and refurbishment markets. Combined with the timber cladding to the verticals of the building, the finished aesthetics of the development blended seamlessly with the surrounding areas.A warm roof build-up that can be made waterproof at multiple stages:For larger projects the Protec system can be made temporarily waterproof at two stages prior to the application of the full waterproofing system. The first stage is upon installation of the sealed, aluminium-faced vapour barrier.The second phase follows the reinforcing of the foil-faced insulation board joints with Protec resin and taping mat. This enables a much more controlled approach to the installation with a greatly reduced chance of rain causing disruption and damage during the works.Highly flexible membrane:Regardless of the size of the roof, Protec forms a homegenous membrane, without a single joint or seam and without the need for any expansion joints.RapidCure technology for quick installation:The application of Protec as a liquid, through to the curing process where a solid, tough membrane that can be walked over, takes only 30 – 60 minutes. This enables large sections of the roof to be fully completed in a short space of time.Installing the Roofing SystemsThe Protec System provided waterproofing to all flat roof areas as well as the extensive parapet wall sections. The roof areas were made up of two designs: the Protec Warm Roof System (approx 7,500m2) and Protec applied to concrete as part of an inverted roof design (approx 1,000m2).The roof installation was carried out with a planned, phased approach that was synchronised to the wider construction schedule. For the warm roof areas, the first stage was to fill the troughs of the structural metal roof deck with acoustic insulation infills that will dampen external noise within the leisure centre. Next, the crowns of the deck were primed ready to receive the self-adhesive vapour barrier.The use of a high-performance aluminium vapour barrier not only eliminates the risk of condensation within the roof, but also provides temporary waterproofing protection, which is extremely useful on larger works such as this.The Polyroof RES Insulation boards, which comprised of a two layer system totalling 170mm to achieve a U-Value of 0.14 W/m2K, were bonded using high-performance PU adhesive to the vapour barrier. Following the wind uplift calculations it was determined that mechanical fixings were not required for this application – making for an extremely rapid installation. As you can probably imagine, fixing through 170mm of insulation into the crowns of the metal deck can be a tricky and time-consuming task.A key advantage of using a tongue and groove insulation system is that the finished surface of the roof is smooth and level without any unsightly board steps that can also lead to standing water issues. The insulation board joints were sealed using Protec resin with Polymat Taping Mat 450 which, in addition to providing additional strength to the joints, also creates a temporarily waterproof layer.For the inverted roof sections, Protec was applied directly to the primed concrete/screed surface. The membrane was inspected by Polyroof Technical Services, signed off and then covered with inverted roof components. An interesting fact when using Protec in inverted roof situations is its incredible durability performance – as tested by the BBA, Protec “can provide an effective barrier to the transmission of liquid water and water vapour for the design life of the roof in which it is incorporated”.Monitoring and CompletionThroughout the duration of the contract, Polyroof Technical Services carried out regular site visits that were reported back to Interserve as part of Polyroof’s free-of-charge contract monitoring service. This enabled the client to keep up-to-date with the progress of the roof installation in detail and also provided peace of mind that the original specification was being closely followed and implemented.Polyroof worked closely with the Roofline Group during the installation, enabling the challenges were identified and solved in an efficient and coordinated manner – saving the client time and money.

First Passivhaus in Wiltshire achieved with help from MEDITE VENT and SMARTPLY PROPASSIV

First Passivhaus in Wiltshire achieved with help from MEDITE VENT and SMARTPLY PROPASSIV

MEDITE SMARTPLY

MEDITE VENT and SMARTPLY PROPASSIV 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 PROPASSIV 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 PROPASSIV 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 PROPASSIV, 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 PROPASSIV 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 PROPASSIV, 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 PROPASSIV provides a winning formula for sustainable building.

Burton Green Primary School

Burton Green Primary School

Polyroof Products Ltd

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.

Rooftop Apartments, Gisburn Rd, Tottenham, Passive Purple

Rooftop Apartments, Gisburn Rd, Tottenham, Passive Purple

Intelligent Membranes

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.

Greener homes: SMARTPLY PROPASSIV installed at eco-friendly development in popular Cardiff suburb

MEDITE SMARTPLY

As part of an exciting regeneration project in Cardiff, Lowfield Timber Frames specified SMARTPLY PROPASSIV panels alongside a supply of their timber kits for a development of 12 two-bedroom houses in Heath, Cardiff.As part of an exciting regeneration project in Cardiff, Lowfield Timber Frames specified SMARTPLY PROPASSIV panels alongside a supply of their timber kits for a development of 12 two-bedroom houses in Heath, Cardiff.The homes are built to strict Passivhaus standards, offering improved health and wellbeing conditions for occupants whilst requiring very low levels of energy for space heating or cooling. Additionally, using timber frame for the construction lowers the carbon footprint of the development.The major benefit of a Passivhaus build is the reduced energy consumption during the operating life of the structure. This will ultimately lead to reduced energy costs, heating bills, and even lower carbon emissions for the planet.The average air test result for the 12 homes came in at below 0.5 ACH. A Larsen truss panel (a lightweight wall extension which creates extra wall space to a house insulation) was also used in the project. It was 330mm deep with the finished wall make-up being closer to 500mm.Darren Jarman, Managing Director of Lowfield Timber Frames, commented: “The Highfields scheme in Cardiff was just one of several passivhaus schemes we have completed over the past 2 years. We now have an external wall build-up that not only meets the passivhaus standards, but also has extremely low embodied carbon credentials.“The external wall has been fire tested and achieves the airtightness required, all in all, reducing the heating requirements and the running costs of the property.”SMARTPLY PROPASSIV is an airtight OSB/3 panel with integrated vapour control and air barrier properties for use as structural sheathing in timber frame structures. The airtightness is engineered into the OSB panel substrate, whilst the factory applied specialist surface finish technology provides increased and constant vapour resistance on the warm side of construction. The panels are suitable for both new build and renovations.The distinctive green layer of SMARTPLY PROPASSIV is a UV cured coating providing increased and constant vapour diffusion factor. In addition, it provides a smooth and durable surface for taping the connections.The panels made to OSB/3 grade, are moisture resistant and can be used in humid conditions (service class 2). The hygroscopic nature of the OSB panel acts as a humidity buffer to help prevent interstitial condensation within the timber frame structure in limited cases of reverse diffusion.Jarman concluded: “Whilst there are other products available which will achieve the airtightness, we feel SMARTPLY PROPASSIV is the most robust solution available and eliminates the possibility of accidental damage, resulting in a failed test.”The ambitious project is part of the ‘Cardiff Living’ programme, a 10-year partnership between Cardiff Council and Wates Residential, which will deliver 1,500 new homes at sites across the city.Discover more about SMARTPLY PROPASSIV and its applications here: https://mdfosb.com/en/products/smartply-propassivFind out more about Lowfield Timber Frames here: https://www.lowfieldtimberframes.co.uk/Twitter: @LTFltd

Blue roof case study: Cambridge University, Department of Civil Engineering

Blue roof case study: Cambridge University, Department of Civil Engineering

Bauder Ltd

This new build project in the centre of Cambridge combines a Sustainable urban Drainage Solution (SuDS) with vegetation and renewable energy in a warm roof construction.The client for the Department of Civil Engineering at Cambridge University, R H Partnership, identified sustainability as being a key driver in the design of the roof, but also sought a single source supplier that could provide a guarantee for both workmanship and products. Bauder’s systems range encompasses products to meet all the sustainability objectives, and with our network of approved contractors carrying out the installation, we could offer the comprehensive guarantee that was required.Bauder Building BoardProject:Cambridge University Department of Engineering​Location:CambridgeRoof Area:1610m²Client:University of CambridgeSpecifier:RH Partnership ArchitectsMain Contractor:SDC LimitedApproved Contractor:Voland LimitedThe specificationTo meet the sustainability criteria set out by the client, the Bauder technical team designed a roof system combining an extensive blue roof, a green roof and a solar PV array. The first and most fundamental element of the roof system though is the waterproofing. Bauder Total Green Roof System (BTGRS) was selected as it provides robust and durable waterproofing with a life span in excess of 35 years, as validated by BBA Certificate 10/4744. The Plant E cap sheet has also been tested by the FLL to ensure long term root-resistance, making it ideal for use in conjunction with the BauderSOLAR G LIGHT system. The BauderSOLAR G LIGHT system is a unique way to combine rooftop vegetation with renewable solar energy. The PV panel mounting boards are held in position using the growing medium as ballast, meaning the waterproofing is not penetrated and therefore compromised. The mounting boards incorporate a water retention feature which allows a small amount of excess rainwater to be stored for short periods of time for the various plant species to feed from. The BauderSOLAR G LIGHT system’s unique mounting system lifts the panels above the vegetation allowing the plant life to grow freely and therefore qualify a greater area of the roof as biodiverse.In addition to the BauderSOLAR G LIGHT system, a blue roof was added to the build-up. Blue roofs are sustainable drainage solutions designed to manage stormwater on a flat roof to reduce water runoff rates and ease flash flooding and standing water in built up areas. The BauderBLUE Roof System attenuates water from a flat roof over a 24-hour period via a restrictive flow outlet. Calculations are carried out to determine the rate at which the water should egress the rooftop. This is determined by the local planning authority and is often set as low as 5-8 litres per second per hectare. With these calculations, Bauder can design each flow restrictorto meet the necessary runoff rate. For the Department of Civil Engineering, the main roof area of 1455.5m² required two flow restrictors, each with flow control holes to ensure the specified discharge rate of 0.77 litres per second was achieved. The maximum depth of water the roof is designed for is the H-max. When the water level reaches H-max, it will drain via the emergency overflow pipe. These overflow pipes are set at the same height as the H-max level. On this project the H-max was calculated to be 99mm. Although an unlikely scenario, this provision for a ‘once-in-a-hundred-years’ storm event will ensure that the structural integrity of the building is always preserved.Project challengesThe roof deck was constructed using a pretensioned concrete plank roof structure. Due to the large span of these planks, the dead load weight to the roof would be restricted. This being a blue roof with green landscaping and PV (a reasonably heavy build up), presented the issue of balancing the need of the roof design and the weight restriction of the supporting structure. To add to this challenging scenario, the pretensioned deck did not provide a completely flat finish. When installing a blue roof, a flat deck with no positive or negative falls is essential, as detailed in the 2018 update of BS 6229 – Flat roofs with continuously supported flexible waterproof coverings. To overcome this onsite challenge,the final deflection of the fully loaded roof was calculated and the concrete deck was screeded to give a flat finish.The resultBauder believes this project to be one of the first of its type in the UK to bring together so many rooftop systems in one space. Project management and clear communication was paramount in order to ensure a smooth installation. The Bauder project team consisted of green roof and solar PV product managers, area technical manager, technical design team, site technicians and approved installers for the waterproofing.With all the different elements being installed, green roof and solar PV product managers worked with our technical team to design the best possible PV array configuration for optimum energy generation whilst also qualifying for the maximum biodiverse area.Bauder site technicians worked closely with Bauder approved contractors, Voland Asphalte Ltd, to ensure works were kept to schedule and that a high quality of workmanship was maintained throughout.To ensure the landscaping is maintained, irrigation was installed by Access Irrigation Ltd. The system, Permadrip Pro, is a drip line irrigation system with anti-syphon design to resist clogging and pressure regulation. Due to the specialist nature of the irrigation system, Access Irrigation Ltd provided a bespoke design service.The result of this network of expertise was a multi-faceted support service for the client, specifier, main contractor and roofing and PV installers. System installed1 BauderPLANT E 42Green, 5mm torch-on root-resistant capping sheet.2 BauderTEC KSA DUOA self-adhesive, elastomeric, bitumen underlayer. This underlayer was used to ensure thorough sealing of lap joints in low temperatures when the roof was installed.3 BauderPIR FA-TETissue-faced flatboard insulation faced on both sides with aluminium foil to provide efficient thermal output.4 Bauder Super AL-ETorch-on air & vapour control layer. Once installed on the concrete pretensioned plank deck, it can act as a temporary waterproofing layer, allowing internal works to be carried out immediately which was a huge advantage on this new build project.

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.

Proteus Waterproofing

Project BriefComprising 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, the contractor, Sussex Asphalte Ltd , 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, Sussex Asphalte Ltd , 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.

Bauder Ltd

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.  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.”

Bitumen Case Study: Whitburn Partnership Centre

Bitumen Case Study: Whitburn Partnership Centre

Bauder Ltd

Whitburn Partnership Centre was designed by Project Architects, Matthew Fair, Neil Forrester and Jamie Bateman at Smith Scott Mullan Associates for West Lothian Council. The design of the contemporary £4M building restores the historic Whitburn Burgh Hall original façade as it is one of the towns most renowned buildings and incorporates a new-build two-storey extension.Located in the centre of Whitburn, this building is a community hub that embraces the West Lothian Council’s model of bringing together services that benefit local communities whilst delivering financial efficiencies through the decrease of council buildings. This building facilitates a library, community halls, museum and customer information service office, making it an important community resource. Project:Whitburn Partnership CentreProject type:New buildLocation:West Lothian, Scotland,Waterproofing:Bauder Total Roof System (BTRS)Roof size: 525m2Energy generated from PV array: 10.35kWp Specifier: Smith Scott Mullan AssociatesMain Contractor: Maxi ConstructionApproved contractor: ProCladd (Scotland) LimitedSolar PV installer: Intelligent Electrical SolutionsThe specificationTo support the West Lothian Council's sustainability objectives of achieving high energy efficiency, it was our responsibility to specify a waterproofing system and provide a solution for natural energy generation. The bituminous Bauder Total Roof System (BTRS) was chosen for this project as it features membranes that can withstand impact and tearing, as well as thermal insulation that met the required U-value of 0.15 W/m²K. This waterproofing system is verified by the BBA and offers a service life in excess of 35 years.The BauderSOLAR system was also specified, as it incorporates photovoltaic arrays for natural energy generation. The photovoltaic mounting system is attached to the roof without penetration of waterproofing or the deck, safeguarding the integrity of the waterproofing to fulfil its full-service life.Project challengesThe Architect’s design incorporated unusually high parapet upstands, which posed a challenge for installers. Area technical manager for Bauder, Christopher Langton, attended design meetings with the Architects and Main Contractor to discuss the best solution for installation. A mutual agreement was made for the underlayer to be mechanically fixed to prevent any slippage of the capping sheet membrane. Due to the height of the upstand, non-combustible insulation BauderROCK was incorporated into the design at these details.The installation of BauderSOLAR F uses prefabricated bituminous BauderK5K membrane sleeves to slip over the mounting plates and welded into position, anchoring the plates to the surface of the Bauder waterproofing system. Approved BauderSOLAR installers, Intelligent Electrical Solutions, installed the BauderSOLAR system, collaborating with ProCladd, approved contractor for the waterproofing installation, and other trades during the roof installation.There is a junction where the flat roof meets the original slate roof of the adjacent building, this detail fell under the torch free zone that hot air welding techniques are used to install the membranes within these areas.The resultInstallation of the Bauder waterproofing system may only be carried out by trained and certified operatives approved by Bauder. A project pre-start meeting was held by Bauder site technician, Duncan Hastings, and area technical manager, Christopher Langton inviting the Site Manager from Procladd and their Bauder badged operatives. During this meeting, they discussed the installation of the project, and identified the areas that required torch-free and torch-safe detailing. They also discussed how the project was going to be delivered in co-ordination with other trades working on the site at the same time, for example cladding and lead that was installed atop the waterproofing upstand details.Weekly site-inspections were carried out by Bauder site technician, Duncan Hastings during the project. Visiting the site frequently meant that Duncan could provide consistent support to the installers and answer any questions they may have had directly. It also meant that the quality of the roof installation was being monitored regularly to ensure it would be to a high standard, achieving the comprehensive guarantee.The approach taken to deliver this project on time and to budget was through meticulous planning and working to tight time frames. The organisation of the delivery of Bauder products to site had to be in line with the schedule to ensure that the site was ready to receive a delivery. With the project located in the busy centre of Whitburn next to a cross junction with traffic lights. This meant that timed delivery of products to site was required in addition to prebooked off-loading by pump truck and tail lift or by telehandler.Health, safety and environment was managed during the planning, design and installation of this project by advising that all installers follow the advice shown in the “Responsible Specification Checklist” produced by the National Federation of Roofing Contractors.In accordance with the Workplace (Health, Safety and Welfare) Regulations 1992, roof edge protection in the form of scaffolding was installed during installation. The project’s perimeters were surrounded by Heras fencing to isolate the construction site from the public. All scaffolds that were on the elevation next to the public had toe boarding and safety mesh where required.As standard, there was a one-hour Firewatch after the Bauder membranes have been installed using a gas torch. This was carried out by Procladd operatives each day when they were working on the project to ensure the welfare of the workforce, and the safety of other trades and that of the building. The 19kg gas cylinders were used on this project as they are easily transportable on the roof area. At the end of each working day, the cylinders were stored in a locked and designated gas storage unit on site.System installedBauder Total Roof System (BTRS)1 BauderK5KElastomeric bitumen torch-on capping sheet in charcoal grey.

Bauder Ltd

Gloucester Transport Hub Bauder Thermofol PVC single ply waterproofing system SynopsisThe replacement bus station and regeneration of the surrounding area has created a unique and distinctive city centre building for the town. The design connects with Gloucester’s Roman heritage and association with aviation. The innovative roof design incorporated a canopy intended to reflect an aircraft wing that required a lightweight waterproofing and renewable energy photovoltaic (PV) solution.Bauder Building BoardProject:Gloucester Bus StationLocation:GloucesterProject Type:RefurbishmentRoof Size:1520m²Constructor: Kier Group PlcApproved Contractor:Kovara Projects LtdThe specificationThe Bauder Thermofol PVC single ply waterproofing system with the BauderSOLAR F PV solution met the brief precisely without compromising the aesthetics of the roof. This combination of Thermofol PVC single ply waterproofing system and BauderSOLAR F PV delivered a high quality, strong, energy efficient flat roof.This system was selected for the project because of its lightweight properties which complemented the deck and roof design. Light grey was chosen to reflect the colour of the cladding as the aesthetics was a key objective for the client.The OMG Rhinobond induction welding system was specified as the installation method which provided multiple advantages to the project, not only saving time and fasteners, but also optimising the field fix pattern of installation and ensuring that the load on the roof was spread between the induction welding plates. Products appliedBauder Thermofol U15 FR MembraneA high grade virgin polymer Thermofol PVC membrane ensures the optimum membrane characteristics to deliver high performance and a BBA stated life expectancy in excess of 35 years.BauderSOLAR F An aerodynamically optimised system for flat roofs using framed modules and mounting units, securing them to the roof using membrane-to-membrane welding techniques. This installation method means that the roof is not compromised by penetrations of fasteners or is it ballasted.Project challengesThe design of the Transport Hub and city centre location proved to be the key challenge to this project. The unusual roof configuration required a bespoke insulation scheme using BauderPIR M, an efficient rebated PIR insulation board, in order to achieve the required U-value of 0.18W/M²K.The deck configuration equally made the installation of the Bauder Thermofol PVC waterproofing system complex with the perimeter zone having to be carefully marked in compatability the wind calculation which included measuring factors such as wind speed, altitude, direction and exposure. Bauder and Kovara Projects were required to work closely together to ensure all criteria of the wind calculations were met. 40 modules of the lightweight BauderSOLAR PV solution were installed on the west side of the Transport Hub’s roof.The location of the project, Gloucester city centre, presented logistical challenges. Delivery of the roofing products had to be carefully scheduled and managed to avoid creating congestion in the area.The resultThe installation required constant co-operation and communication to embrace the live site operations within the restricted city centre location whilst allowing the bus station to remain fully functional. The roofing contractor delivered a superior standard solution and any complex issues that arose during the project were resolved promptly and collaboratively.System installedBauderThermofol PVC single ply waterproofing system  1 Bauder THERMOFOL U15 FR1.5mm polyvinyl chloride membrane (PVC) reinforced with a pre-coated polyester cross-weaved matting for mechanically fixed installations. 2 BauderPIR MThis efficient tissue-faced flatboard insulation has been specially developed for use within Bauder single ply systems. 3 BauderSYN DB-PE 100A blue, polyethylene air and vapour control layer.

Nine Elms Parkside Case Study: Under Screed Acoustic Layer

CMS Danskin Acoustics

Nine Elms Parkside: Under Screed Acoustic LayerWhen carrying out a large-scale housing development it pays to rely on tried and tested products to provide acoustic certainty. Regupol 7210C (REGUPOL sonus core 5) is one such product. With a long history of reliability, it is now being installed in the UK’s largest single-phase build to rent development.The ProjectNine Elms Parkside is the redevelopment of a 5.6 hectare Royal Mail depot site in Wandsworth, a key part the Vauxhall Battersea Opportunity Area, sitting between Battersea Power Station and Nine Elms market and adjacent to the new US Embassy. The scheme is master planned around the new Nine Elms Linear Park, part of a new green link connecting Battersea Park in the west, along the Thames to Lambeth Palace Gardens in the east.Blocks B and D Nine Elms Parkside were acquired in 2019 by real estate groups Henderson Park and Greystar who contracted Telford Homes to construct 641,000sft of residential space to a design by Allies & Morrison.The scheme consists of 894 build to rent apartments in two twin blocks of 10 to 17 storeys, each of which also features 12,500sft of amenity space with a rooftop swimming pool, gym, pet spa, children’s play space, private dining rooms, cinema rooms and a sky lounge. There are two large outdoor terraces, yoga gardens and community herb gardens complete with beehives. The scheme will also contain 25,000 sq ft of retail and community space.CMS Danskin is supplying Regupol 7210C (REGUPOL sonus core 5) Acoustic Resilient Layer to Stanmore, the leading drylining and façade specialist subcontractors who are carrying out the screeding between floors in the apartments.The project to supply commenced in 2020 and we have to date supplied over 96,000m2 of the product. Topping out took place in July 2021, residents will begin to occupy the scheme in 2022 and the units are expected to be fully complete in 2024.Acoustic insulation for new build apartmentsSince 2004 the Building Regulations require that separating floors between apartments meet specific requirements for airborne and impact sound transmission. The requirements are set out in Approved Document E, Resistance to the passage of sound.With a 150mm concrete slab, common in multi storey new build apartments under 18 storeys, a product is required to isolate the structure from a floating screed, thereby significantly reducing impact and airborne noise and enhancing the living conditions of occupants of the apartments.Regupol 7210C (REGUPOL sonus core 5) Acoustic Resilient Layer is an isolating layer specifically designed for this purpose and is the go-to product for floating screeds over 150mm concrete slabs.Regupol 7210C (REGUPOL sonus core 5) Acoustic Resilient Layer isA high performing insulation that delivers superior impact and airborne performance.An under-screed product designed to isolate screeds from the main structure simply and conveniently.Manufactured from recycled materials – typically aircraft tyres – making it cost effective and sustainable.Compatible with all types of floor screed, making it adaptable across a project and between projects.Aimed at constructions where Pre-Completion Testing (PCT) is preferred to a Robust Detail (RD) approach.Testing under screed insulation for acoustic performancePre-Completion Testing of acoustic floor installations gives a contractor more flexibility, allowing alternative layouts between apartments. If the designer wants to make changes to the layout of apartments, they won’t need to change the Robust Detail as each eventuality can be tested on site. With a project of over 860 flats a 10% required test rate would produce 86 acoustic tests, but the flexibility of using a PCT solution like 7210C (REGUPOL sonus core 5), and its reliability as an established product, makes that regime cost effective.Telford Homes, a long-standing customer of CMS Danskin, were looking for a Pre-Completion Testing product for Nine Elms blocks B and D. Regupol 7210C (REGUPOL sonus core 5) Acoustic Resilient Layer is an established product from an established brand, so not only were Telford Homes familiar with the product, but their experienced screeders Stanmore were also confident that testing on site would not raise any issues.Over a year into the project all the tests carried out so far have been successful.Supply chain reliabilityFor a large project with over 100,000m2 of product required over a long contract period, reliability of supply is essential. Any delay in supply can hold up wet trades and affect the critical path. With support from our supply chain partners, CMS Danskin has ensured over 96,000m2 of product has been delivered on time to date.Specify Regupol 7210C (REGUPOL sonus core 5) Acoustic Resilient LayerRegupol 7210C (REGUPOL sonus core 5) Acoustic Resilient Layer is a tried and tested solution to under screed insulation over a concrete slab, be it in apartments, hotels, education buildings or student accommodation.

Triple Layer vs Double Layer Polycarbonate Rooflight

Triple Layer vs Double Layer Polycarbonate Rooflight

Trade Access Panels

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.

Rada the right medicine for infection control

Rada the right medicine for infection control

Rada

The decision to close and refurbish the ward allowed a total rethink in terms of infection control and prevention, as well as improved ergonomics, patient comfort and privacy. The hospital’s infection control team worked with its capital projects department to put infection control at the top of the agenda for the new ward’s design, which saw 30 of Rada’s Acu non-touch digital thermostatic mixing valves installed, replacing 13 conventional taps. Rada Sense was chosen for the ward’s shower areas.While the remit was to specifically bring effective non-touch controlled hand-washing and showering facilities to the new ward, water management and maintenance was also seen as important. Paul Scott of the capital projects team said:” The estates department wanted a move away from old style elbow taps because of the labour intensive aspect of having to flush each tap manually.With Rada’s T-LogicTM digital intelligence controlling both the Acu and Sense products, it allows them to operate, communicate and exchange information with the mixing valves to ensure that high degrees of safety, hygiene and control are maintained.” Testimony to the effectiveness of the revamped ward has come from the nursing staff, many of whom worked in the original ward, and whose feedback has been very positive. Dr Beryl Oppenheim, a specialist in infection control, said:” From the outset we wanted to put infection control at the very heart of the day to day running of the new ward. From our point of view the ward in its new guise has certainly raised the bar in this respect.”In addition to the Rada Acu and Sense installations, the refurbished 25-bed unit also features floor signs in front of each hand basin with the words ‘Wash your hands’ and hand washing facilities outside the ward door.

Frontier Pitts Security Height Roadblocker provides Anti-Ram Traffic Control protection to a Local Council Authority

Frontier Pitts Security Height Roadblocker provides Anti-Ram Traffic Control protection to a Local Council Authority

Frontier Pitts Ltd

Neath Port Talbot Borough Council contacted Frontier Pitts to upgrade an existing road blocker and tag system. The existing system had been installed for over twenty years.The Road Blockers are used to permit access for buses only, through an area where other vehicles have previously used the road as a bypass to avoid other traffic hotspots in the area.The Tag System Technology has progressed greatly in the last twenty years, and the Council were keen to upgrade the system. The same system is also installed and has been in use at Swansea University since 2018. This was to ensure vehicles from both sites could use the same tags across both access control systems.There was also an issue with vandalism in the area, so consideration had to be given to ensure the readers are installed appropriately, to avoid damage.The BenefitsVehicle can be detected at up to 10 metresUHF vehicle tags are inexpensive and easy to fit to vehiclesAvoids the need for manned gatesPrevents unauthorised vehicle accessUsing the same technology readers expanded the system enabling buses to access both sitesThe SolutionFrontier Pitts worked with Nortech Controls who recommended the uPASS Target readers. The readers have a read range of 10 metres so they could be mounted on high access control posts, to solve the problem of vandalism.Neath Port Talbot Council said: “After twenty years of maintenance and support, our local traffic control system needed to be upgraded. We are pleased we could work with Frontier Pitts and Nortech Controls again with the new installation.”

Birmingham Control Tower

Birmingham Control Tower

Knauf Insulation Ltd

ChallengeFor the air traffic controllers at Birmingham Airport, concentration is critical to ensuring the safety of the hundreds of passenger jets that take off and land every day. Studies show office workers lose concentration when noise levels hit 55dB; however, the sound of just one medium-sized aircraft descending at 1,000ft is 70dB.SolutionWith this in mind, noise reduction was an essential factor in the specification of the insulation for the 105ft air traffic control tower. The airport’s developers consulted Knauf Insulation’s Technical Support Team for advice. The Technical Support Team recommended Rocksilk® RainScreen Slab, a non-combustible Rock Mineral Wool insulation designed for use in high-rise rainscreen façade systems.Mineral Wool insulation has superior acoustic performance because of its open structure, which traps sound between the individual strands and turns it into heat energy.Rocksilk® RainScreen Slab is quick and easy to install and adapts to minor imperfections in the substrate. Slabs are flexible and knit together eliminating air gaps for maximum acoustic and thermal performance, making it perfect for use on the curved walls of the funnel shaped control tower. The same level of acoustic performance could not have been achieved with rigid foam boards, which have closed cell structures that offer virtually no sound absorption. Rigid foam boards are also more prone to air gaps, reducing acoustic performance further.As well as excellent acoustic and thermal performance, Rocksilk® RainScreen Slab is non-combustible with Euroclass A1 reaction to fire classification. This means it will not contribute to the spread or development of fire should it occur.Another factor in the specification of Rocksilk® RainScreen Slab was sustainability. It is manufactured with ECOSE® Technology, Knauf Insulation’s unique bio-based binder, which 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 binder, so it is more environmentally friendly. Products made with ECOSE® Technology generate low levels of dust and VOCs, and have been awarded the Eurofins Gold Certificate for Indoor Air Comfort.Thanks to Rocksilk® RainScreen Slab the air traffic controllers at Birmingham Airport can enjoy a quieter, warmer, safer and more sustainable workplace."Acoustic protection, energy performance, fire safety and sustainability were all crucial factors taken into account during the design of the air traffic control tower and so all materials specified with the project needed to meet these multiple requirements. We are extremely pleased with the building."Will Heynes, Birmingham Airport’s Development Director

Riser Doors and Access Controlled Doors for Multi-level Data Centre

Riser Doors and Access Controlled Doors for Multi-level Data Centre

EBD Steel Doors (formerly Eurobond Doors)

We were approached to design & manufacture a range of steel fire-resistant riser doors and personnel doors for Europe's most advanced data centre, located in Canary Wharf, London.This 8-storey building offers 73,400 sqm of space - they needed simple yet secure riser doors to provide fire protection to the internal ducts, containing all the cabling and plumbing required in a sleek, discreet solution that provided maximum access, performance and safety.Alongside the riser doors, Eurobond designed & manufactured personnel doors that could be electronically controlled to control the access and provide an audit trail of personnel movement.The 2 key elements of this project were the riser doors - and the sheer volume required to cover the 8 levels and the access control requirements that had to be well planned and coordinated by Eurobond, the security contractor, end-user and architect.
