Breathable Membrane UNNEO is a high-performance roofing underlayment designed to protect the roof structure while allowing moisture vapour to escape. Its breathable construction helps reduce condensation and supports proper moisture management beneath the roofing system.
Breathable Membrane UNNEO
Manufactured in Ontario with stable lead times and predictable output. Direct access to production helps you get answers fast and keep projects on schedule.
We use premium German steel with durable coatings for long service life and consistent geometry. Better corrosion resistance and a clean, uniform finish.
The membrane provides reliable water resistance and acts as an effective wind barrier, helping protect insulation and structural components from rain, wind, and moisture. With high vapour permeability, Class W1 water resistance, and UV resistance for up to 180 days, it is suitable for demanding roofing applications and changing weather conditions.
Lightweight and flexible, Breathable Membrane UNNEO is easy to handle and install across large roof areas. The 1.5 m × 50 m roll provides approximately 75 m² (806 sq. ft.) of coverage, helping improve installation efficiency and reduce the number of joints.
Designed for long-term performance, the membrane is suitable for use as a protective underlayment beneath metal roofing systems and other compatible roofing assemblies.
