ProctorPassive Wraptite SA

Self-Adhering Airtight and Vapour Permeable Membrane for Wall and Roof applications

Product Overview

ProctorPassive Wraptite-SA consists of triple layer polyolefin textile with a proprietary acrylic moisture vapour permeable adhesive and release liner.

It combines the best properties of a vapour permeable membrane and a self adhesive water and air barrier in one innovative self-adhering product. Use of highly vapour permeable self-adhesive membranes decreases installation times when compared to mechanically fastened membrane systems and is suitable for residential, commercial and high rise buildings.

Continuous contact of the membrane to the sheathing by even distribution of stress over the entire bonded surface allows better resistance to wind pressures and elimination of stress point concentrations.
