Procheck A2, with its Class A2-s1,d0 fire classification to BS EN 13501-1, is considered non-combustible with no contribution to fire. Its composition comprises of the glass fibre backing, with a pure aluminium foil and clear lacquer coating. This composition affords the membrane its Class A2 performance as well as giving it a high degree of vapour controlling properties.
The membrane comes with a high vapour resistance, as well as being air-tight, which allows its use as an AVCL in construction. Providing high levels of airtightness can ensure the thermal efficiency of the building.
Features
Reaction to Fire classification to A2,s1-d0
Water vapour diffusion tight
Clear lacquered aluminium allows for low emissivity surface
