Introduction
Enviroseal™ ProctorWrap™ Residential Wall (RW) is a light duty vapour permeable wall wrap designed for use in residential timber and steel frame wall construction.
Product Description
Enviroseal™ ProctorWrap™ RW is a triple layer polyolefin non-woven textile. The high water vapour permeability of Enviroseal™ ProctorWrap™ RW 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.
Applications
Enviroseal™ ProctorWrap™ RW is a highly vapour permeable, 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™ RW 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™ RW 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 form on the rear face of the cladding.
Adequate provision for the drainage, absorption or diffusion of moisture is required exterior to the membrane to ensure that moisture is not left trapped between the Enviroseal™ ProctorWrap™ RW and the external cladding. This is especially important for vapour tight or non-absorbent claddings such as steel.
Care should be taken when installing insulation so that this does not restrict drainage within the cavity.
Benefits:
- High water resistance
- Non-perforated
- Highly vapour permeable
- Air tight
- Light weight and easy to handle
- Quiet when exposed to wind
- Soft facings reduce flapping noise
