EnglishEnglishRoofing membrane is a high-performance underlayment that provides additional waterproofing and moisture control beneath roofing materials.
Roofing membrane protects the roof structure from wind-driven rain, snow, and dust while allowing trapped moisture to escape. As a result, it reduces the risk of condensation, mould, and structural damage.
In addition, the material improves overall roof performance and supports long-term durability in demanding weather conditions, including the Canadian climate.
Multi-Layer Structure
The membrane features a multi-layer construction that combines an advanced non-woven polypropylene outer layer with a functional diffusion layer and a durable inner backing.
This structure allows controlled vapour permeability while maintaining strong resistance to water penetration.
Moreover, the material remains lightweight and flexible, which simplifies installation and handling on site.
INSTALLATION AND COMPATIBILITY
Contractors can install the roofing membrane directly over rafters or sheathing. Therefore, it adapts easily to different roofing systems, including metal, tile, and shingle roofs.
In addition, the material provides excellent stability during installation and performs well in complex roof geometries.
