Best selling product for new installations and refurbishment projects

Risk of condensation — the product is a vapour control layer and will reduce the risk of interstitial condensation 

Air permeability — the product is an air barrier and can reduce heat loss by air infiltration 

Thermal insulation — the product can contribute to limiting heat loss through walls and floors 

Strength — the product has adequate strength to resist the loads associated with the construction of the wall or floor 

Properties in relation to fire — the product is classified as Class E in accordance with EN 13501-1 : 2007. 

Durability — the product will have a lifetime equal to that of the building element in which it is installed. 

NHBC: In our opinion if installed, used and maintained in accordance with this Certificate, can satisfy or contribute to satisfying the relevant requirements in relation to NHBC Standards, Chapters 6.2 External timber framed walls, 6.9 Curtain walling and cladding, 6.10 Light steel framed walls and floors and 9.2 Wall and ceiling finishes 

The product’s highly reflective and durable surface reduces heat loss through the roof, ceiling, wall or floor, therefore enhancing the thermal performance of the system. The upper and lower layers are made of aluminium polyethylene film and the inner part is reinforced with PP network, which gives this foil insulation an extremely high tensile strength. 

The top layer of polyethylene is metallized with the heat-reflective surface of aluminium. The internally reinforced membrane sheet covers both the structure from the ingress of water, acting as a reliable heat absorption layer. 

Floors – under floor boards, carpets / vinyl, tiles and laminate floor and between floor joists 

Underfloor Heating – under heating pipes (wet and dry systems) 

Ceilings – between ceiling joists and under plasterboard 

Roof – can be used in ventilated and non-ventilated roofs 

Walls – in dry lined stud walls and against solid walls 

This Aluminium foil membrane is an air barrier and vapour control layer with a low-emissivity aluminium foil face on one It is placed on the warm side of the insulation with the foil surface facing the interior of the building. A typical wall and floor installation is shown in Figure 1. 

The shiny side of this product should face in-towards the room when installed. 

The product is positioned on the warm side of the thermal insulation and held in place by staples at approximately 500 mm centres to the background Joints between adjacent sheets of the material should be lapped 100 mm over a support and be sealed with a strip of our self adhesive Aluminium foil tape 

At all penetrations and abutments the product is cut neatly to fit as closely as possible and the joint sealed with a strip of our self adhesive Aluminium foil tape. Penetrations must be kept to a minimum. 

The product is made vapour- and convection-tight at all window and door openings and at other detailing. The membrane is sealed tight against the frame with our self adhesive Aluminium foil tape and compressed with a timber batten fixed over. All membrane laps and penetrations should be sealed with our self adhesive Aluminium foil tape 

Internal lining must be set on spacer battens, leaving a minimum gap of 25 mm behind the lining to accommodate wiring and other services and reduce the need for penetrations of the vapour control layer/air barrier. When used without a void, the product does not contribute to the thermal value of the construction but continues to act as a vapour control layer/air barrier 

The product is either installed above or beneath the floor boarding and beneath the internal floor 

Joints between adjacent sheets of the material should be lapped 100 mm and be sealed with a strip of our self adhesive Aluminium foil tape 

This foil membrane is satisfactory for use as an air barrier and vapour control layer in conventional timber-frame, masonry and steel-frame walls and floor 

The product is effective in reducing the U value (thermal transmittance) of walls and floors in which it is installed. Further information is given in BRE Report BR 262 : 2002. 

Walls in new buildings should be designed and constructed in accordance with the relevant recommendations of the UK National Annexes of BS EN 1996-1-1 : 2005 and BS EN 1996-2 : 2006. 

Suspended concrete and suspended timber ground floors incorporating the product must include suitable ventilation. 

Walls  

a cavity > 20 mm thick, 67 m2·K·W–1 

Floors  

a cavity > 17 mm thick, 58 m2·K·W–1 

a cavity > 25 mm thick, 0.80 m2·K·W–1. 

Foil insulation can reduce the radiant heat transfer by up 97% 

Excellent stability, strength and cohesion 

Highly tear resistant 

Corrosion and damage resistant 

Good nail tear resistance 

Helps prevent mould and damp, enhances thermal resistance, and reduces risk of condensation 

Specially designed to keep homes warm in winter, but the unique foil properties are also great at reflecting excessive heat during the summer 

A much more cost-effective alternative to other vapour barriers / aluminium foil membranes scarcely available in builder’s merchants 

Low-emissivity reflective surface used to improve the overall u-value of the building helps to meet the requirements of Approved Document Part L 

Extremely economical and waste-free Very lightweight and easy to cut (no special equipment required) 

Offers a real ease of application 

High weather resistance 

Multi-layered aluminium 

Thermally insulating properties: equivalent to 55mm Polystyrene Insulation 

Ideal for use in both Refurbishments & New Builds 

Prevents the ingress of water/moisture and the passage of wind-blown snow and dust into the interior of the building 

The reflection foil is designed for direct application in underfloor heating systems; under heating pipes and can be easily cut to fit shaped areas. The foil reflects heat and deflects the cold temperature down to prevent heat loss to the subfloor and increase the system’s efficiency
