Fireshield® chosen for science centre of Kensington & Chelsea school

Fireshield® chosen for science centre of Kensington & Chelsea school

A Proctor Group Ltd

Fireshield® vapour permeable membrane, which is designed specifically to improve the fire protection behind cladding has been chosen for a new Science Centre at Bevington Primary school in the Royal Borough of Kensington and Chelsea, London.The project includes a brand new Science Studio, plus before and after school club buildings.SIP Build UK was appointed as frame subcontractor for the project and chose the Fireshield membrane as part of the SIPS panelling system. Chris Duckworth from SIP Build UK explains: “We chose Fireshield as it provided the project with a number of really important benefits. Fireshield is a high-performance breather membrane which enables us to achieve the requirements in terms of fire protection without compromising on vapour control.Fireshield was also ideal because it is easy to use and allowed us to achieve the requirements in one process, using just the membrane, rather than the typical approach of two, cement board and a membrane.”Fireshield is the culmination of leading research to produce a vapour permeable membrane with a intumescent coated surface, which has a unique composition that actively reacts to help protect the materials underneath. The intumescent coating helps protect the substrate by reducing the risk of fire taking hold and significantly reduces the formation of droplets and smoke.The BBA Certificate awarded to Fireshield confirms that it has enhanced performance in relation to reaction to fire classification, will reduce the risk of interstitial condensation, and will have a life equal to that of the building in which it is installed.Fireshield complies with BS5250, BS4016 and NHBC requirements for vapour permeable walling underlays. It is installed and fixed to the substrate in the same manner as standard breather membranes using mechanical fixings. Applications include both commercial and residential buildings including apartments and student accommodation, as well as Rainscreen cladding and applications over 18m high (11m in Scotland).

Procheck A2, the high-performance fire-resistant vapour control layer system from the A. Proctor Group has been selected as part of a £6bn regeneration project that will create over 10,000 homes in Enfield, London, over the next 20 years.Leading regeneration specialist Vistry Partnerships has been appointed for the first phase of the Meridian Water scheme working in partnership with Enfield Council. Meridian One will see the development of 1,000 new homes with a mixed tenure of private sale, private rent (PRS) and 50% affordable housing spanning 13 blocks ranging in height from four to twelve storeys. In addition, the scheme incorporates 2,235m2 of employment space and over 2 hectares of green, parkland and open space.Sam Bennett, Commercial Director at SCL LONDON, a Structural Framing Systems and Drylining specialist, commented.“Procheck A2 was selected because it has a Class A2 performance and excellent vapour-controlling properties. In addition, the membrane comes with a high vapour resistance and is airtight, allowing its use as an AVCL.This means that Procheck A2 provides high levels of airtightness which ensures the thermal efficiency of the building.”“Procheck A2 has an A2-s1,d0 fire classification to BS EN 13501-1, is considered limited combustibility and minimal contribution to fire, and therefore, conforms with the requirements for high rise construction (18m).” The superior performance of Procheck A2 from the A. Proctor Group is the perfect solution, delivering significant benefits to the combination of in-factory manufacture and on- site housing construction.Procheck A2 comprises a unique design consisting of a glass fibre backing with a pure aluminium foil and clear lacquer coating. It is this clear surface which provides Procheck A2 with the added benefit of a low emissivity surface, which, when used with a service cavity, can enhance the overall thermal performance of the building fabric, as well as ensure a high fire protection performance, with an A2-s1,d0 fire classification. Procheck A2 is designed to protect the building fabric from the potential risks of condensation whilst providing the added benefit of serving as an effective airtight barrier.Sam Bennett added,“the technical team at the A. Proctor Group supported us throughout and provided comprehensive installation guides giving vital information for both operatives and clients and helping with sign-off at specific hold points throughout the project.” Based on years of investigation, research and development, the A. Proctor Group can offer a superior range of technically advanced membranes to address the safe design of fire solutions in building construction.The installation of Procheck A2 will ensure a high level of protection throughout the building’s lifespan.

Procheck Adapt - Montrose

Procheck Adapt - Montrose

A Proctor Group Ltd

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.

Procheck® 500 - BAS Signy Cummins Hut

Procheck® 500 - BAS Signy Cummins Hut

A Proctor Group Ltd

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.

Roofshield - S&J Roofing, Bath

Roofshield - S&J Roofing, Bath

A Proctor Group Ltd

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.

Spacetherm Multi - Bath

Spacetherm Multi - Bath

A Proctor Group Ltd

The heat efficiency of a Grade II listed Georgian townhouse in the historic city of Bath is set to be dramatically improved as a result of the introduction of Spacetherm® Multi insulation.The challenge of dealing with heating inefficiencies, major heat loss and high heating costs are a common problem with many listed buildings and solid wall dwellings.Property owner Mike Mower explains, “I obtained planning permission to insulate the top floor of my Grade II listed Georgian townhouse as it is single skin 6” Bath stone (Oolite) and very heat inefficient, all walls have the original lime render and skim and so they need to breathe. The property in Bath was built in 1818 and has been in my family for 101 years since 1919! I am the 3rd generation to live in it and it was last renovated in 1935 so it needs serious upgrading!“The architect originally specified another insulation but this would have required encroaching 100mm into the room and would necessitate moving door frames and rebuilding window reveals. After extensive research, I identified the Spacetherm Multi aerogel product from the A. Proctor Group.“The architect was so impressed by the thermal efficiency of the Spacetherm Multi. With a total thickness of 20mm when rendered, this will not encroach onto the floor space, and the door frames and windows will not need to be altered. Subsequently we included Spacetherm Multi on the planning application as an alternative to the traditional insulation originally specified, which was approved by the Conservation officer and building control.”In addition to the Spacetherm SLENTEX® A2 blanket, foil encased Spacetherm A2 (CBS) Cold Bridge Strip was also included at window and door junctions to address areas susceptible to cold bridging.Spacetherm Multi is a high-performance laminate specifically designed to be laid directly onto existing floors & walls. Spacetherm Multi consists of Spacetherm Aerogel insulation blanket bonded to a 6mm Magnesium Oxide Board.At just 16mm thick, the use of Spacetherm Multi has virtually no negative impact on floor space, making it ideal for refurbishment projects where space is at a premium.Typically, a solid wall will have a U value of around 2.1 W/m2K. Following the application of Spacetherm Multi, this can be reduced to around 0.8 W/m2K, dependent on the wall structure.Finally, Mike Mower commented “I think Spacetherm Multi is ideal for listed building insulation as it has a minimal effect on the infrastructure of the original building. It has the potential to be used extensively in old buildings such as we have in Bath where heat loss is at a maximum, the original walls need to be able to breathe when insulated and insulation has hitherto been impossible due to the visual impact encroaching on the listed building. I am also seeking planning permission to use the product to insulate the basement floor and walls.”

Spacetherm WL - Paris

Spacetherm WL - Paris

A Proctor Group Ltd

A classic Parisian apartment is benefitting from the thermal effectiveness of the introduction of the innovative ultra-thin Spacetherm® WL insulation.Located in the 11th arrondissement in the heart of Paris on Boulevard Voltaire and overlooking the Place de la Republique, the two-bedroom, 135sqm apartment was built in the Hausmann style. Hausmann’s renovation of Paris was part of a major programme commissioned by Emperor Napoléon III in the late 19th century, resulting in the distinctive appearance of the wide avenues, parks and squares which have become associated with this beautiful city.Property owner Keirnan Murphy has made a significant investment in the renovation of the apartment to improve overall comfort, energy efficiency and to reduce heating costs.Keirnan explains, “The solid stone walls, whilst adding to the building’s charm, result in heating inefficiencies and higher heating costs. During summer the stone walls warm during the day, retaining and radiating heat throughout the night. In winter, the solid walls cool down leading to a huge increase in heating costs.We undertook lots of research on solutions for green and energy-efficient renovations. In the research, we considered products available within France and as well as those available internationally. The Spacetherm WL aerogel insulation from the A. Proctor Group was a perfect choice for the apartment. At just 13mm thickness, the Spacetherm WL fits inside the lip of our cornices, which average about 20mm. Typically the walls of these older properties are not completely flat and so the option of an ultra-thin insulation was critical. Most alternatives were thicker and would not have worked.We are very pleased with the results and we noticed that when leaning up against the Spacetherm WL you can feel your back warm against the insulation. The A. Proctor Group were extremely helpful in addressing all the questions from the architect and ourselves. They also provided comprehensive support and guidance to our builder on the installation.”Spacetherm WL is a high-performance laminate specifically designed to be fixed to the internal surfaces of existing solid walls without the need for mechanical fixings. Spacetherm WL consists of Spacetherm aerogel insulation blanket bonded to 3mm Magnesium Board (MgO), for use in applications where improved thermal performance is required with limited space.Typically, a solid wall will have a U value of around 2.1 W/m2K. Following the application of Spacetherm WL, this can be reduced to around 0.8 W/m2K, dependent on the wall structure.

Wraptite - Charleston Farm

Wraptite - Charleston Farm

A Proctor Group Ltd

A new self-build farmhouse in the beautiful Scottish countryside has been fitted with the high-performing Wraptite air-barrier. The project is designed to Passivhaus standards by Architect Frances Strachan-Friar. Talla Fiodha (‘timber or wooden hall’ in Gaelic), Charleston Farm, near Errol, Perthshire, will be the new home for Frances and her husband.From the outset, the aim was to achieve a more sustainable design and follow a different approach from the traditional timber kit. After undertaking significant research into different types of construction, the architect selected Xilonor CLT cross-laminated timber installed by Glulam Solutions Ltd., Inverurie.Frances Strachan-Friar commented on how the selection of Wraptite has benefitted the development. “The specification of the correct type of airtightness barrier was critical in achieving thermal efficiency. Wraptite was chosen because it allows the airtightness layer to be fitted to the outside of the construction. In doing so, the external application of Wraptite provides essential protection in the form of waterproofing and weatherproofing for the CLT during the build.“The Wraptite system was great and easy to apply, especially around junctions, enabling us to seal all of the junctions completely. The use of a traditional membrane would not have given the same performance. I have previously specified products from the A. Proctor Group, but this was the first time using Wraptite. Proctors provided a comprehensive Toolbox Talk and have been a great support throughout the project.”The Wraptite system is the only self-adhering vapour permeable air barrier certified by the BBA. It combines the critical properties of vapour permeability and airtightness in one self-adhering membrane. As a result, it provides high vapour permeability in a continuously sealed, airtight membrane.The high vapour permeability of the Wraptite air barrier allows the substrate beneath to dry quickly and moisture vapour to escape and reduces the likelihood of mould, mildew, condensation, timber distortion and metal corrosion. The vapour permeability of Wraptite also allows any water vapour to escape efficiently, thereby avoiding interstitial condensation problems.Designed to replace traditional airtightness methods cost-effectively, Wraptite is a low-resistance vapour permeable air barrier, durable, flexible and lightweight, allowing for easy installation, with the added benefit of providing temporary protection against the elements during construction

The completion of a stunning new Hilton hotel at Silverstone is another step nearer and leads the way featuring the superior high-performance Wraptite external airtightness barrier.The impressive new hotel, located trackside, overlooks the starting grid for the home of the iconic British Grand Prix. Facilities include 197 guest rooms, a rooftop terrace and the offer of race-day hospitality experiences.KKA Architecture designed the hotel, with Metclad Contracts appointed as the specialist envelope contractor for the project.Wraptite airtightness membrane from the A. Proctor Group, specialists in supplying high-performance products to protect buildings, was selected by Metclad to maximise airtightness and energy efficiency, perfectly balanced with the crucial requirements of vapour permeabilityWraptite self-adhesive breather membrane is applied externally, quickly and efficiently as part of the rainscreen system. Incorporating the Wraptite System helps ensure “as-designed” performance. Its inclusion narrows the gap between asdesigned and actual energy performance whilst reducing the likelihood of possible failures to meet required airtightness levels.Traditionally air barriers have been fitted internally. The internal installation of an air barrier necessitates accommodating building services such as electrical, lighting, heating and drainage systems, thereby increasing the gap between as designed and built. However, the Wraptite membrane fully bonds externally to virtually any substrate, requiring no additional mechanical attachment, seals or tapes to suppress air leakage around junctions or penetrations.The high vapour permeability of Wraptite allows the substrate beneath to dry quickly and moisture vapour to escape and reduces the likelihood of mould, mildew, condensation, timber distortion and metal corrosion.Wraptite is the only self-adhering vapour permeable air barrier certified by the BBA and combines the critical properties of vapour permeability and airtightness in one self-adhering membrane. Quite simply, providing a winning performance in advanced membrane technology for buildings.
