Choose a roof membrane that performs under real site conditions. The Forte 145 breathable membrane delivers strength, flexibility, and reliable moisture control.
This four-layer membrane uses a reinforced grid structure that resists nail tears and handling damage during installation. It lays flat quickly and drapes correctly between rafters, helping water move safely towards the eaves.
The membrane allows water vapour to escape from the roof space, which helps reduce condensation around insulation and timber. Its low vapour resistance supports a healthier roof structure and limits long-term moisture build-up.
A hydrophobic surface treatment pushes water away instead of letting it sit on the membrane. This improves performance during installation and exposure to weather.
Installers benefit from its durability and ease of handling on-site. It performs consistently across both new build and refurbishment projects.
The Forte 145 membrane suits cold and warm roof systems when installed according to the current building regulations. Each roll measures 50 metres by 1.5 metres, providing 75 square metres of coverage.
