VapourTech® RWC Roof Wall Commercial is an Air Barrier, Water Barrier and Class 4 Vapour Permeable pliable building membrane. Very high levels of water vapour are allowed to absorb and diffuse through the core and non-woven structure, ensuring that condensation risk is controlled, while outside liquid water cannot penetrate inwards. With remarkably high permeance, Classified as Class 4, Vapour Permeable, VapourTech® RWC Roof Wall Commercial meets the vapour permeance requirements of the NCC 2022 in ABCB Climate Zones 4 to 8 and is suitable for use in ABCB Climate Zones 2–8.
VapourTech® RWC Roof Wall Commercial performs as an all-weather barrier to air, wind driven rain and dust penetration from the outside of the envelope. VapourTech® RWC Roof Wall Commercial is non-conductive, has excellent UV resistance and is chemically non-reactive in conjunction with treated timber and salt conditions close to coastlines.
