Aluminium paper composite vapour barrier
Aluminum paper ARVO PE is a vapour-proof and strong vapour barrier. It is used as an internal vapour barrier of wet rooms, to prevent the penetration of water vapour into the constructions and insulation layers. The vapour barrier is installed on the side of the construction where the partial pressure of the water vapour is the highest (usually on the warm side) so that the aluminum surface is installed towards the air layer or warm room. The material is fixed in the direction of the carcass racks with the help of fastening rivets or nails. To ensure even greater impermeability, the seams can be sealed with a aluminium tape.
