A vapour permeable waterproof membrane for use with standing seam sheet metal roofs in copper, zinc, aluminium and stainless steel and can be laid on timber board or rigid insulation.

Manufactured with an outer layer of polypropylene mesh bonded to a vapour permeable membrane, it is laid between the timber deck/ insulation and the outer metal roof covering. It can be laid vertically or horizontally and fixed using non-ferrous staples or flat head clout nails on the overlap.

The product will prevent condensation that occurs on the underside of the metal roof covering from re-entering the roof structure and offers protection against any external moisture that may penetrate the outer roof covering. It can also provide an air space below zinc coverings to allow protective oxidation to form.
