Lead-Free Roof Flashing Membrane Designed for a Variety of Applications

MFM Building Products, a manufacturer of a full envelope of waterproofing and weather barrier products for the building industry, offers a new innovative roof flashing membrane – GreenWeld PVB. GreenWeld PVB armored flashing system is a high-performance PolyVinyl Butyral (PVB) 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. According to the manufacturer, it is easy to cut and use, heat-weldable, non-toxic, sustainable, flexible and lightweight, 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 inches, 20 inches and 39 inches by 19.5-foot-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.

New Roof Flashing Provides All-Weather Maintenance

New Seal-Fast Repair Hero roof flashing from Mule-Hide Products Co. is an all-system, all-weather maintenance and repair product.

A universal solution, the solvent-based, fiber-reinforced terpolymer sealant adheres to all roof substrates, including asphalt, modified bitumen, metal, TPO, EPDM, PVC, Kynar, concrete, Elvaloy/PVC, Hypalon (CSPE) and polyisobutylene (PIB).

Ready to work in all conditions, Repair Hero can be applied to dry or wet surfaces and under water. It can be used in any weather – rain or shine and in any ambient temperature.

According to the manufacturer, its exceptional elongation and high tensile strength enable Repair Hero to out-perform asphalt-based cements and silicone-based roof patches.

  • It delivers excellent adhesion, out-sticking silicone-based patches in TPO and EPDM applications.
  • It withstands soaring temperatures and intense exposure to ultraviolet light – conditions that can cause asphalt-based cements to become brittle and crack.
  • It is 50 percent more elastic and more than 9 times stronger than silicone-based roof patches, enabling it to better withstand building movement, foot traffic and the poundings dealt by Mother Nature.

Repair Hero complies with VOC-related regulations in all 50 states and does not need to be mixed or stirred before use and does not skin over or separate in the can after opening.
