Application

Air & Vapour Control Layer for use in a warm roof flat roofing system. Top surface with heat-activated THERM-stripes for adhering certain insulation types.

Description

Elastomer bitumen air & vapour control layer, self-adhesive with variable technology for lap sealing. The two side laps of the membrane have differing finishes. On one lap there is a self-adhesive finish, whist the opposite lap has a glass fleece. This allows the membrane to be sealed with either a gas

torch or hot air welder.

Only to be used as part of a full Bauder Waterproofing System.
