Protect pitched roof constructions with Cromar Vent3 Pro Green, a breathable roofing membrane developed for reliable performance beneath tiles and slates. The vapour-permeable construction allows moisture vapour to pass through the membrane while providing an additional layer of protection against wind-driven rain, snow and dust. Lightweight and easy to handle on site, Vent3 Pro can be installed quickly across roof areas and provides a practical alternative to traditional roofing felt. Its breathable properties help manage moisture within the roof construction, reducing the risk of condensation and supporting a healthier roof environment. Supplied in a 50m long by 1m wide roll, each membrane provides 50m² of gross coverage, making it suitable for new roofs, extensions and refurbishment projects. The roll format also makes measuring, cutting and positioning straightforward during installation.
