This felt is commonly used as a waterproof membrane owing to its ingenious design which incorporates two layers of non-woven polypropylene with a microporous film. When installed as part of your roofing system, you’ll be assured that no unwanted damp or cold air will make it into the inside of your home.
Measuring just 0.45mm in thickness, the Wonderbuilds WonderVent 100 Classic Breathable Felt features the slimmest profile of the entire range. It is also the lightest at just 100g/m² which makes handling and installing this felt an absolute breeze. Better yet, you won’t have the worry of a rooftop that is under intense strain.
