ASTON BUILDING SUPPLIES LTD ABS Breathable Membrane 100GSM Roofing Felt – 1m x 50m Roll | Roof Felt Underlay for Sheds, Slated & Pitched Roofs | Breathable Roofing Membrane for Use Beneath Tiles

The ABS Breathable Roofing Membrane is a high-performance 100GSM roof underlay designed to provide reliable protection for both roofing and walling applications. Manufactured using vapour permeable and air barrier technology, this low-resistance breather membrane allows moisture vapour to escape from the building structure while preventing water penetration from external elements. Ideal for use beneath roof tiles and within pitched roof systems, the membrane helps reduce the risk of condensation, damp, and trapped moisture, improving the long-term performance of the roof structure. It is also suitable for sheds, timber frame buildings, walling systems, extensions, garages, and general construction projects. Supplied in a convenient 50 metre x 1 metre roll, this lightweight yet durable membrane is easy to handle, cut, and install on-site. The strong 100GSM construction provides excellent tear resistance and dependable weather protection during installation and after completion.
