The 1m x 50m Breathable Roof Membrane is a high-capacity, heavy-duty underlay engineered to provide exceptional weather protection and vapor regulation for standard to large-scale pitched roofing projects. Measuring 1 meter in width and extending to a generous 50-meter length, this roll offers substantial coverage that reduces the frequency of roll changes on site, making it a favorite among professional builders and contractors. Installed beneath tiles or slates, it acts as a reliable secondary defense against wind-driven rain, snow, and dust while effectively managing internal moisture to prevent condensation buildup in the roof space.
 
Constructed from advanced multi-layer spunbonded polypropylene, this membrane combines high tensile and tear strength with a lightweight profile for easy handling and rapid installation across rafters. Its durable composition ensures excellent resistance to damage from fixings and temporary UV exposure during the construction phase. The micro-porous design allows trapped moisture vapor from inside the building to safely escape, keeping underlying roof timbers and insulation dry, secure, and protected from rot or mold.
 
Designed to meet rigorous industry standards, this 1m x 50m breathable membrane rolls out smoothly and features clear alignment lines for precise overlapping and stapling. By enhancing the overall thermal efficiency and weather-tightness of the property, it ensures long-term structural integrity. Whether you are working on a residential development or a major home extension, this high-performance underlay delivers trade-quality reliability from the rafters up.
