Prefabricated bituminous membrane
Pre-fabricated waterproofing membrane with the specific function of an absolute vapour barrier. The compound is made of distilled bitumen and elasto- Plastomers (APP type), reinforced with a rot-proof fiberglass mat and aluminium metal sheet that allows to obtain a barrier against the passage of vapour.
The bituminous DIMPLED FACED VAPOUR BARRIER MEMBRANE on the exposed side features a series of embossed dimples (more than 1000 per m2), formed by a special heat activated compound which ensures a strong and durable adhesion to the insulating panels. The advantages of the bituminous DIMPLED FACED VAPOUR BARRIER MEMBRANES are basically those aimed at avoiding the use of oxidized bitumen and cold bonding substances (mastic, polyurethane glues) for the application and adhesion of insulating panels.
