voalit perfor

It is a plastomeric bitumen sheet that provides vapour drainage of the waterproofing system. It is used to ensure the adhesion of the spot bonded membrane to the surface.

It is applied freely without overlapping and bonding. The first layer of the membrane is flame–torch bonded providing melt bitumen penetration through the holes of VOALIT PERFOR. It is spot bonding and the damp reached to the roof structure distributes between the spots and ventilates through the exhaust outlets. This is the way to avoid the forming of air blisters.
