Corotop Strong is a breathable roofing membrane that can withstand heavy loads and increased friction. It is a good choice for fully-boarded roofs. Covered with two layers of durable non-woven polypropylene fabric protects the roof against dampness, which creates an efficient vapour permeability and effective water-tightness.

With a low Sd value, Corotop Strong is a great alternative to the likes of Proctor Roofshield.
