Long Lasting Waterproofing Protection That's Performance Proven
The self-adhered flexible flashings from Grace Construction Products -- Perm-A-Barrier® Vycor® Plus and Vycor® V40 Weather Barrier Strips -- provide superior protection against water, air and moisture intrusion. They are made of highly adhesive rubberized asphalt compounds, completely and integrally bonded to high density, cross-laminated polyethylene with a paper release liner.
They resist puncturing, tearing and self-heal to resist leaks from minor cuts. They also self-seal around fastener holes put through membranes.
