LaGrange, Ohio - A new roofing system from West Development Group (WDG) includes spray polyurethane foam (SPF) insulation, as well as silicone sheet, skylight glazing, silicone sealants and coatings, and other products for commercial or industrial roofing.
In WDG's System 14 roofing, a zero-VOC coating (HSS 535) is applied over the soya-polyol-based SPF, "creating a moisture-resistant seal that is both durable and flexible," the company claims.
The Ohio roofing supplier says that using "an SPF base with thesilicone topcoat offers a long list of benefits." SPF is seamless,watertight, and lightweight. It eliminates flashing leaks, lowersinstallation costs, and is easy to maintain. Polyurethane foam'sinsulating properties can generate significant energy savings, WDGpoints out.
Silicone topcoats cure in a few hours, forming a seamless, self-flashing seal, said LaGrange-based WDG. They resist oxidation, wind-driven rain and snow, ozone, and many chemicals. In addition it resists cracking and peeling and will not shrink or become brittle or stiff.
Roof systems using these materials can often pay for themselves with energy savings within the warranty period, the company commented.
WDG also claims to be the only roof system manufacturer to use recycled EPDM to strengthen and enhance the physical properties of its silicone topcoat for new projects. Using recycled material from old roof prevents tonnes of old roofing material from being tossed into landfills, the roofing specialist explained.
