ProctorWrap Air Tight (AT) breathable membrane by Dynamic Composite Technologies


ProctorWrap Air Tight (AT) is a triple layer polypropylene textile developed primarily as a breathable membrane for use with timber and steel frame wall construction behind rain screen cladding's and as a vapour permeable underlay for supported metal roof applications.

ProctorWrap AT affords effective protection during construction and for the life of the building against rain, snow and dust, and 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.

In combination with taping overlaps, ProctorWrap AT forms an air tight wrap for the building reducing the loss of heated air or cooled air from the building thus improving the energy efficiency of the building envelope.
