Construction Membranes: ProctorWrap Commercial Wall

ProctorWrap Commercial Wall

Enviroseal ProctorWrap CW is a light duty vapour permeable wall wrap designed for use in commercial steel and timber frame wall construction.

The high water vapour permeability of Enviroseal™ ProctorWrap™ CW allows for the controlled escape of vapour from within the building whilst restricting the ingress of liquid moisture, thus helping to protect the building fabric and insulation from condensation and related problems such as mould, timber rot, corrosion and loss of thermal resistance.


Enviroseal™ ProctorWrap™ CW is a highly vapour permeable, very tough, light duty wall wrap for use as a sarking in timber and steel frame wall construction. It is tear resistant making it easy to handle during installation. In combination with taping overlaps, Enviroseal™ ProctorWrap™ CW can help form 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.

It is good practice for Enviroseal™ ProctorWrap™ CW to be separated from the exterior cladding by a cavity to allow for the drainage of any moisture that has penetrated the exterior cladding or condensation that may formed on the rear face of the cladding. Although Enviroseal™ ProctorWrap™ RW can be used as temporary protection during construction, it cannot be used as a primary waterproofing membrane and should not be left exposed to UV for longer than 2 months. For rain screen and UV exposed applications, please use Enviroseal™ ProctorWrap™ Black Label.
