Roofing Felt

Breathable Membrane – High-Performance 160gsm Roofing Underlay

Our breathable membrane is a three-layer, highly breathable and fully waterproof roofing underlay, engineered from high-tensile spun-bonded polypropylene surrounding a microporous polypropylene film for maximum durability and reliability.

Layer Functions:
• Outer Layer: Provides the primary waterproof barrier, protecting the roof from wind-driven rain.
• Middle Layer: Acts as the core breathable membrane, allowing controlled moisture vapour to escape while maintaining complete waterproof integrity.
• Inner Layer: Adds abrasion resistance and extra strength, preventing damage during installation and long-term use.

This advanced construction allows vapour to pass through effortlessly while keeping water out, ensuring a healthier, longer-lasting roof structure. At 160gsm, this membrane is lightweight, easy to handle, extremely strong, and designed for roofers who want reliability without the hassle. Perfect for keeping roofs watertight while still allowing essential ventilation.
