Next Generation Heat Mirror® IG product guide Commercial applications True design freedom—with glass that insulates like a wall With thermal insulation approaching that of the surrounding walls, Heat Mirror® multicavity insulating glass (IG) units enable architects and engineers to design curtain wall, storefront, and operable window systems that meet the most stringent requirements for energy efficiency and occupant comfort. Heat Mirror insulating glass contains one or more clear, low-emissivity films suspended within the sealed airspace of a dual-pane IG unit to create up to four superinsulating cavities that buffer against heat loss or heat gain. By combining with high-performance low-emissivity glass and argon or krypton gas fill, Heat Mirror IG can be used to tune envelop performance by either maximizing or minimizing solar heat gain while optimizing daylighting and views. In fact, Heat Mirror IG helps reduce energy costs with center-of-glass U-value as low as 0.05 that maintains a warm glass surface temperature for a comfortable internal environment year round. Higher performance, lighter weight, and lower environmental impact than triple pane Heat Mirror IG weighs up to 33% less than comparably sized triple-pane IG, eliminating the need for expensive reinforced framing systems or additional installation labor, which makes it an ideal drop-in solution for standard framing systems designed for dual-pane IG. Also, a comprehensive Life Cycle Analysis completed by Eastman shows that replacing the third lite of glass with film enables Heat Mirror IG to consume 30% less energy cradle to gate than triple-pane IG.1 And because film is practically weightless, multiple films can be used to reach a new level of insulating performance needed for the latest Passive House, Net Zero Energy, and LEED Platinum/Gold-rated designs.
