The GreenWeld™ PVB armored flashing system is a high-performance PVB (PolyVinyl Butyral) membrane enhanced with an aluminum scrim for superior flexibility, strength and weathering. The membrane is comprised of recycled PVB in the monolithic membrane, which can be heat-welded to itself at the seams.

The flashing is designed as a replacement for lead, sealant pockets or liquid flashing systems were the cap flashing ply is the GreenWeld PVB membrane. It can be used in both residential and commercial roofing applications. In commercial (flat roofing) applications, the membrane is used in conjunction with an approved 2-ply modified bitumen system, single-ply or a target patch base sheet to form a complete flashing system.

Some applications require GreenWeld Adhesive/Sealant, a single component, polyether structural adhesive designed for difficult bonding and sealing applications. GreenWeld Adhesive/Sealant is VOC compliant, strong and flexible, offers low temperature flexibility, and experiences no slump. Please refer to the Installation Instructions below for application usage.
