ProctorWrap High Perm
wall applications

ProctorWrap High Perm (HP) is a spun bonded polypropylene material developed primarily as a breather membrane for use in timber and steel frame wall construction. ProctorWrap HP affords effective protection during construction and for the life of the building against rain, snow and dust. ProctorWrap HP is a highly durable, strong and lightweight textile membrane that is silent when exposed to wind and will last the lifetime of the building even in corrosive coastal environments.

Unlike foil products, the high water vapour permeability of ProctorWrap HP allows for the controlled escape of vapour from within the building whilst restricting the ingress of moisture. All Proctor Roofshield and ProctorWrap breathable (vapour permeable) membranes have a vapour resistance of not more than 0.5 MNs/g when tested to AS/NZS 4200.1.

ProctorWrap HP will help protect the building fabric and insulation from condensation and related problems such as mould, timber rot, corrosion and loss of thermal resistance.

ProctorWrap HP is classified as light duty in accordance with the value specified for bursting strength.

ProctorWrap HP is not suitable for roofing applications.
