Polyfresko G SA is a highly reflective, granular surfaced APP modified bitumen roofing membrane meant for self-adhering applications. It is constructed with a high-performance polyester reinforcement providing exceptional tensile strength and dimensional stability. The product is manufactured by Polyglass U.S.A., Inc. using the company’s patented ADESO dual-compound self-adhesive technology. Polyfresko G SA features patented FASTLap for granule-free roll ends, as well as SEALLap, a factory-applied adhesive treatment at the membrane overlap for easy installation. Polyfresko G SA has a highly reflective granular surface and features patented CURE Technology-a thin film that is applied during the manufacturing process resulting in a roof surface resistant to granule loss and discoloration. Bright white, Polyfresko G SA membrane has shown after accelerated weathering that it maintains its reflectivity and white appearance. It is listed with the Cool Roof Ratings Council with an initial SRI of 96 and is California Title 24 compliant.
VaproShield announces the WrapShield SA Self-Adhered System has completed the process of obtaining a Declare label. The Declare program was launched in 2014 by the International Living Future Institute (ILFI), founder of the Living Building Challenge, to promote greater transparency in the building products industry. Referred to as a “nutrition label” for building products, Declare labels list all of the materials found in a given product, as well as its assembly site, life expectancy, and other key details to facilitate informed decisions toward positive human and environmental health. The Declare program aims to give people and businesses greater power when deciding what products to surround themselves with in their home or office.
“While VaproShield products undergo numerous internal and external audits to ensure overall healthfulness and sustainability, finally the Declare label makes it easy to present this information in a tangible way,” says Phil Johnson, managing partner. “We are excited to give our business partners the power to know exactly what goes into the product that is held within the walls of their structure.”
WrapShield SA Self-Adhered System is the first water-resistive barrier (WRB)/air barrier self-adhered sheet good membrane system to earn a Declare label placing the system at the forefront of the transparency movement. In order to qualify for a Declare label, a building product must either be free of, or declare any harmful Red List chemicals, and meet all Appropriate Sourcing Imperatives as determined by the ILFI. WrapShield SA Self-Adhered required no changes to its formulation or material components, because it was designed to be free of harmful ingredients.
“We are excited to participate in such an innovative program,” says Johnson. “It embodies our own sustainability philosophy in that [VaproShield] believes sustainability is as much about creating positive environmental impacts as it is about reducing negative ones.”
Domestically produced in the Midwest, the WrapShield SA Self-Adhered System creates a breathable, energy-efficient, continuous air barrier system that helps prevent moisture from becoming trapped in the building envelope. This can reduce instances of mold, mildew and rot, while helping maintain better indoor air quality and a more enduring building structure. An entirely self-adhering product, WrapShield SA Self-Adhered allows for quick installation that never requires the use of chemical primers.
