Procheck® A2 stands as a vapor and air impermeable membrane. Procheck A2 is deemed non-combustible and fire-neutral. Its constitution comprises a glass fibre backing, a pure aluminium foil layer, and a transparent lacquer coating. This structure not only imparts the membrane’s Class A2 performance but also endows it with potent vapor regulation properties. Delivering substantial vapor resistance while maintaining airtightness, the membrane serves as an Air and Vapor Control Layer (AVCL) in construction. Ensuring robust airtightness can significantly enhance the building’s thermal efficiency.
