Description
Permavent GRAPHITE is a vapour-permeable roofing underlay designed for use as a secondary weather barrier within pitched roof constructions. It is suitable for installation in new-build and refurbishment projects.
It meets the requirements of BS 5534:2014+A2:2018 and is suitable for installation beneath tiled or slated pitched roofing systems in accordance with the standard. Its physical properties allow it to perform as a continuous underlay layer when correctly lapped, contributing to weather resistance during and after installation.
