SFBA MP is waterproof and resists the passage of moisture through walls, floors and ceilings. SFBA Met Poly is a multi-layer air bubble insulation with external layers of aluminium metalized PET. This provides a corrosion resistant and water tight insulation system. It can be used for insulating under floor, in walls, in dry lining such as for cellars and can also be used in greenhouses and other industrial applications. SFBA reflects heat, just like a mirror reflects light. SFBA is an ideal radiant barrier for supplementing existing insulation to keep your house warmer is winter and cooler in summer. SFBA is a high performance insulation and can utilise low emissivty air gaps to maximise the thermal capabilities. SuperFOIL SFBA is the UK’s leading bubble foil insulation. SFBA is designed to maximize insulation performance with a quick and easy installation. SFBA is an ideal radiant barrier for supplementing existing insulation, helping to keep your house warmer in winter and cooler in summer. Single bubble double foil.

Application SFBA should be installed on the "warm" side of the insulated structure, with special care being taken to ensure that all seams and holes are sealed effectively to render the whole structure moisture and vapour proof and to improve thermal performance. It is important that SFBA is installed as a continuous barrier in order to prevent vapour entering the wall or the roof. Fixing & jointing All laps should be a minimum of 50mm and be sealed using SF jointing tape. Particular care is required when sealing around penetrations. Where the barrier is breached by construction elements, the aperture should be sealed with SuperFOIL tape.
