VaproShield (Gig Harbor, Wash.), a developer of breathable membrane systems for walls and roofs, announced the introduction of ReNewShield, a patent-pending, vapor-permeable air- and weather-resistive barrier made with 70% post-consumer recycled plastic.
The recycled plastic (PET 1) is based on material from water and soda bottles, and the membrane is reported to pass all testing and criteria in its class, including ICC-ES AC 38 and ASTM 2178 (air barriers), and ASTM E-84 (Class A fire rating). With a perm rating of 75, the membrane allows moisture vapor within the building to escape, ensuring indoor air quality, the company says.
More information about the testing criteria is available at www.astm.org.
The membrane can be used in all types of commercial and residential construction; can withstand 120 days of UV and climate exposure prior to cladding; and is covered under the company’s standard VaproShield warranty.
The product also is reported to meet the criteria of Environmental Quality (EQ) credit 4.1: Low-Emitting Materials: Adhesives & Sealants, under the U.S. Green Building Council's LEED rating Ssystem for New Construction and Major Renovations (LEED-NC), version 2.2., and core and shell (LEED-CS), version 2.0.
Lee Snyder, the company’s managing partner, said the product “gives architects and design professionals a new alternative for creating a ‘green' rainscreen building envelope. Plus, it's just a good thing for the planet to recycle the 30 billion plastic water bottles that are disposed of each year.”
The company estimates that for every square foot of ReNewShield used, it is recycling 2.35 10-oz. water/soda bottles, or 70,000 bottles for every 30,000 square feet of membrane produced.
VaproShield offers high-performance building-envelope systems, including breathable membranes, rainscreen design components, and 3D window flashing elements.
