Permavent - Breather Felt
Due to high performing functional film (polypropylene) and increased strength parameters in the production process, the product has an upgraded degree of watertightness ( well over 6000mm H²O), which means that it is highly resistant to water and moisture while providing the opportunity to carry out assembly work in any atmospheric condition. Special UV stabilising agents allow the product to have an increased resistance to UV rays (even up to 4 months !!), meaning that the final covering of the roof can be delayed to a later stage. PERMAVENT-MAX can be used on cold vented, non-vented, warm deck and hybrid roofs (habitable roof space).The name speaks for itself.
