The PHS 120 Roof & Façade Breather 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 120 Roof & Façade Breather Membrane offers superior protection against condensation risk and extreme resistance against pelting rain. PHS 120 is a Diffusion-Open vapour permeable membrane. When sealed at the overlaps and other appropriate building components, the PHS 120 Roof & Façade Breather Membrane provides a windtight environment underneath resulting in optimum thermal performance of the insulation.
