PPG to Preview Passive Solar, Low-e Glass At International Builders Show

PPG Industries will exhibit samples of a new passive solar, low-emissivity glass at the 2012 International Builders Show in Orlando, Feb. 8-11, along with CLARVISTA® shower glass and a dual-pane, dual-coat insulating glass unit (IGU) that enables residential windows to achieve R-5 “center-of-glass” insulating performance.

Visitors to the PPG booth (W3417) can preview a new passive solar, low-e glass by PPG that is designed for residential use in colder, heating-dominated climates. PPG will formally introduce the product in early 2012.

PPG also will display Clarvista glass, a shower door and enclosure glass that, with regular maintenance, looks newer longer than do competing products. It is made with a coating that seals the glass surface, enabling it to resist corrosion caused by heat and humidity. When combined with STARPHIRE® ultra-clear glass by PPG, Clarvista glass produces an exceptionally transparent shower glass, making it ideal for upscale homes, resorts and commercial spas.

PPG will showcase an IGU made with one 3-millimeter pane of its new passive solar, low-e glass on the fourth (#4) surface and SOLARBAN® 60 glass on the second (#2) surface, separated by a ½-inch air space. The configuration yields R-5 insulating performance at the center of the glass.

R-5 windows, which by definition have a U-value of 0.22 or less, are emphasized in federal legislation and adopted in building codes to improve the energy efficiency of single-family homes and multifamily residential buildings.

PPG’s dual-pane, dual-coat technology enables window manufacturers to make better-insulating products without multi-cavity IGUs, which can complicate the manufacturing process and add to the cost of windows for builders, remodelers and homeowners.

PPG also will feature its complete line-up of energy-efficient SUNGATE® low-e glasses and Solarban solar control, low-e glasses.
