Corotop BigBand
Corotop BigBand is single-sided adhesive tape made of highly vapor-permeable polypropylene membrane and acrylic dispersion. Applied to membrane damage, it ensures continued vapor permeability. It is a component of the Corotop Thermo Red (PIR) over-rafter thermal insulation system, providing wind and gas tightness to frame structures (used as a termination for roof valleys and ridges). Its split liner facilitates application.

The roofer's opinion:
Highly permeable, three-layer roofing membrane with a weight of 140 g/m², constructed of a functional film protected on both sides by a non-woven polypropylene fabric. It provides resistance to water seepage and regulates the flow of water vapor through the roof system. Available with 40 mm wide adhesive strips.
