Corotop Blue Breathable Membrane

Corotop Blue Breathable Membrane


The Three Layer Roofing Breathable Membrane

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 three layer membrane is highly resistant to mechanical damage and outside factors including UV- rays and high temperatures.
