MFM Offers GreenWeld™ PVB Lead-Free Flashing Membranes

MFM is proud to announce that we are now offering GreenWeld™ PVB flashing membranes for roofing applications. GreenWeld PVB is an armored flashing system composed of high-performance PVB (PolyVinyl Butyral) enhanced with an aluminum scrim for superior flexibility, strength and weathering.

Independent tests show that GreenWeld PVB has the same waterproofing properties of traditional lead and liquid flashing used to seal roof penetrations. Because it is flexible, GreenWeld can be installed in extreme conditions without trouble and can be heat-welded for strong, watertight seams.

The product comes in pre-packaged rolls in 39” x 19.5’, 20” x 19.5’ and 10” x 19.5’ roll lengths. Product is sold in rolls. As part of the GreenWeld system, we also offer GreenWeld Adhesive/Sealant in 10 oz. tubes for use with the GreenWeld PVB membrane. The Adhesive/Sealant if VOC compliant, strong and flexible, has low temperature flexibility, and no slump properties.
