ProctorPassive Wraptite SA

Product Description

ProctorPassive Wraptite SA combines the best properties of a vapour permeable membrane and self-adhesive water and air barrier in one innovative self-adhering product. Wraptite SA utilizes a patented full coverage air permeable adhesive to provide unsurpassed vapour permeability in a commercial quality, self-adhered, water-resistant vapour permeable membrane.


Wraptite SA’s high vapour permeability allows sheathing to dry quickly and moisture to escape. This ensures good indoor air quality by reducing the likelihood of mould, mildew, condensation, timber distortion and metal corrosion.


Wraptite SA should be installed in accordance with the supplied installation guide. Wraptite SA fully bonds without mechanical attachments to most substrates for ease of installation, requiring minimal use of sealants or tapes.
