PPG Industries has announced that SOLARBAN® R100 glass, SUNGATE® 400 glass & CLARVISTA shower glass have earned Cradle to Cradle® Certification at the Silver tier. PPG earned Cradle to Cradle® Certification for all its architectural glass products in 2008. Solarban R100 glass is a neutral-reflective, solar control, low-emissivity glass with visible light transmittance (VLT) of 42%, a solar heat-gain coefficient (SHGC) of 0.23, and a 1.79 light-to-solar gain (LSG) ratio that is up to 29% greater than that of competing products in the same architectural glass category. Sungate 400 glass is a passive, low-E glass with a magnetron-sputtered vacuum deposition (MSVD) soft coat that helps commercial buildings in heating-dominated climates retain heat from the sun and reduce winter heating costs. Clarvista shower glass for shower doors & bath & shower enclosures has proven through industry-standard tests that, with regular maintenance, it looks newer longer than other shower glass products.
