Ametalin 1500mm x 30m VapourTech Wall Vapour Permeable Wall Insulation

VapourTech® Wall is classified as Air Barrier, Water Barrier and Class 4 Vapour Permeable. Very high levels of water vapour are allowed to absorb and diffuse through the core non-woven structure, ensuring that condensation risk is controlled, while outside liquid water cannot penetrate inwards. VapourTech® Wall is chemically non-reactive in conjunction with treated timber and salt conditions close to coastlines. VapourTech® Wall is used as a wall wrap behind fibre cement and timber cladding in most Australian climates. VapourTech® Wall is a high permeance building membrane made with three-layer construction: two tough outer layers of spun-bonded fabric protecting an inner core of homogenous high permeance film.
