LAGRANGE, OHIO—West Development Group (WDG), a leader in sustainable roofing products and practices, introduces solvent-free R2R silicone, a key component of the company’s System 14 Total Silicone Roof System. WDG’s System 14 features zero VOC coatings (HSS 535 and HSS 540 R2R) that are applied over a soy-based Spray Polyurethane Foam (SPF), creating a moisture-resistant seal that is both durable and flexible for any commercial roofing situation.
WDG’s exclusive R2R process positions the company as the only roof system manufacturer to use recycled EPDM material to strengthen and enhance the physical properties of its silicone topcoat (HSS 540 R2R) for new roofing projects. Using reclaimed material from old roof tear-offs, the R2R process improves an array of WDG products and prevents tons of old roofing material from being tossed into landfills. Disposed EPDM takes 10,000 years to degrade.
R2R solvent-free silicone topcoat is a one-of-a-kind, sustainable, and environmentally friendly product that is economically viable and functionally equivalent to traditional petroleum-based roofing materials. Use of solvent-free silicone on a 100,000-square-foot roof prevents the release of approximately 1,000 gallons of solvent into the atmosphere—enough petroleum to drive a family sedan around the world.
An R2R system is an energy-conscious system that delivers long-term performance and easy maintenance. R2R documentation is available regarding pertinent testing, codes, standards and conformance to industry standards and guidelines, including ASTM, UL, and FM.
WDG silicone topcoats cure in a few hours; form a seamless, self-flashing seal; resist oxidation, wind-driven rain and snow, ozone, and many chemicals; offer resistance to cracking and peeling and will not shrink or become brittle or stiff; and eliminate most tear-offs. The silicone surface can be easily reconditioned to provide years of further leak-free service.
