The PHS 180 Roof Membrane is the Next Generation of High-Performance vapour permeable Underlay.
With an impressive range of characteristics such as high Vapour Permeability, Extreme Watertightness, High Nail Tear Resistance and Thermostability. PHS 180 Roof Membrane offers superior protection against condensation risk and extreme resistance against pelting rain. PHS 180 is a Diffusion-Open vapour permeable membrane. When sealed at the overlaps and other appropriate building components, the PHS 180 Roof Membrane provides a windtight environment underneath resulting in optimum thermal performance of the insulation.
