Corotop Beige Breathable Membrane

Description

A High Resistance Breathable Membrane

The membrane’s high resistance to mechanical damages enables safe work at a height regardless of weather conditions.

Corotop Breathable Membranes form the water impermeable layer under the roof coverings in a pitched roof system. They can be used on open rafter (unsupported) or fully supported pitched roofs. The function of the underlay is to isolate the building from water ingress that may penetrate the roof coverings such as wind driven rain. In addition, the low vapour resistance of the underlays can, when correctly incorporated into a designed roofing system, assist with the satisfactory management of water vapour within the roof system.
