MFM LEAD-FREE ROOF FLASHING MEMBRANE

MFM Building Products, a manufacturer of a full envelope of waterproofing and weather barrier products for the building industry, is proud to offer a new innovative roof flashing membrane – GreenWeld™ PVB.

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 and can be used in residential and commercial roofing applications. Typical applications include flashing for pipe penetrations and support beams, water barrier for cavity walls, liner for valleys of shingle, tile and aluminum metal roofs, and through-wall flashings.

GreenWeld PVB is designed as a replacement for lead, sealant pockets or liquid flashing systems. The membrane offers the roofing contractor significant advantages including: easy to cut and use, heat-weldable, non-toxic and sustainable, flexible and light weight, and comes with a 20-year warranty. Independent, third-party testing shows that GreenWeld has the same waterproofing properties of traditional lead used to seal roof penetrations.

GreenWeld PVB is available in roll widths of 10”, 20” and 39” by 19.5’ length rolls. Each roll is pre-packaged in a shrink sleeve for protection until use. Some applications require GreenWeld Adhesive/Sealant, which is also available from the company.
