Breathable Felts

Explore our wide range of Breathable Roofing Felts, designed to provide superior ventilation and weather protection for pitched roof structures. Ideal for both warm and cold roof designs, breathable felts allow moisture to escape from the roof space while preventing water ingress, helping to reduce condensation and prolong the life of your roofing system. Suitable for new builds and refurbishments, our felts are lightweight, easy to handle, and compliant with BS5534 and Building Regulations Part L.  Shop now for high-quality breathable felts with fast UK delivery and competitive trade prices.
