CCW-705-TWF Thru-Wall Flashing is designed to provide moisture management in cavity wall construction. The CCW-705 TWF system is installed to divert water to the exterior at interruptions/terminations of the cavity including base of wall, shelf angle, window head/sill and head of parapet wall. Its self-adhesive nature allows easy installation on concrete, masonry, gypsum, steel and wood substrates.

The CCW-705-TWF Thru-Wall Flashing is a 40-mil-thick composite membrane consisting of a 32-mil self-adhering rubberized asphalt membrane laminated to a smooth surface, 8-mil, cross-laminated, high density polyethylene film. A siliconized release liner prevents the material from sticking together in the roll, and is easily removed for installation. CCW-705-TWF is available in convenient widths of 12″, 18″, 24″ and 36″. The factory-controlled quality ensures uniform thickness on the job, while the inherent waterproofing properties of the rubberized asphalt membrane provide an excellent water barrier. The heavy polyethylene film is resistant to cuts and tears.
