Insulated Glass Solutions Create Windows that are 30% More Energy Efficient
Industry leaders partner on highly energy efficient insulated glass solutions for commercial windows and doors
Southwall Technologies and Dow Corning released on November 9th, the lightest weight and most energy efficient multi-cavity insulated glass available for large glass-intensive projects (according to claims by the companies). The product is the result of an energy-efficient Heat Mirror “S” film and 982FS two-part structural silicone sealant and is available for commercial buildings in North America. The multi-cavity insulated glass allows architects and window manufacturers to increase energy savings by up to 30 percent, block over 99 percent of UV radiation and reduce sound transmission by up to 20 percent over dual-pane glass. Video below.
The high energy efficiency of the multi-cavity insulated glass is the result of the suspension of one or more of Southwall's energy-saving Heat Mirror "S" films inside of an insulating glass unit to create two or more super-insulating cavities. This creates a high performance glass that is 33 percent lighter than typical triple-pane glass solutions. Southwall's insulated glass is compatible with Dow Corning 982FS two-part structural silicone sealant and Dow Corning 982-H Curing Agent and, when combined with these products, the Heat Mirror “S” film delivers greater energy efficiency than traditional dual-pane glass.
“Until now, there has not been a viable super-insulating glass solution in North America for large-scale, structural glazing projects,” said Dennis Capovilla, president and chief executive officer of Southwall Technologies. “Dow Corning’s two-part silicone sealant provides a solution and opens up North America’s commercial building market to our industry-proven Heat Mirror technology.”
Dow Corning 982FS and Dow Corning 982-H Curing Agent are designed for use as secondary sealants in dual-sealed insulated glass units. Dow Corning has the only approved silicone sealants that can be used as a secondary edge seal in multiple pane insulated glass units using Southwall Heat Mirror “S” film. Curing to form a durable, long-lasting and flexible silicone seal that is chemically stable, 982FS creates a weather-tight bond and offers excellent unprimed adhesion to glass. The silicone insulated glass sealant’s unique weatherability enables it to retain design properties even after years of exposure, ultimately enhancing commercial buildings’ durability levels and structural capabilities.
