Procheck® A2, is a vapour and airtight membrane. BS EN 13501-1 confirms that Procheck A2 is considered to have limited combustibility and will not significantly contribute towards the fire load and fire growth. 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 airtight, which allows its use as an AVCL in the construction. Providing high levels of airtightness can ensure the thermal efficiency of the building.
