Because of its insulating capabilities, Heat Mirror IG has been specified for some of the highest performance net-zero energy and LEED-certified buildings, such as the retrofit of the 6,514 windows in the landmark Empire State Building.
Current ENERGY STAR-rated windows that use dual-pane IG with low-emissivity (“low-E”) coatings have reached fundamental performance limits. This is driving a shift from “coatings to cavities” in which “multi-cavity” IG technologies, such as triple-pane that uses three layers of glass to create two airspaces, are required to achieve the next level of performance. However, triple-pane technology is heavy, typically limited to smaller sizes, and requires costly reinforcement to window frames and sashes to handle the added weight.
Unlike glass, suspended film is practically weightless, making Heat Mirror IG an ideal drop-in performance upgrade for windows without the size and weight limitations of triple-pane. And state-of-the-art manufacturing now makes this performance more accessible to consumers who want to enjoy large, beautiful views without sacrificing energy efficiency. Heat Mirror IG also blocks +99.5 percent of ultraviolet radiation to prevent premature fading of drapes, carpet, furniture, floors, and photographs, and can reduce outside noise up to five decibels better than standard dual-pane IG.
Backed by automated manufacturing and a 20-year warranty, next-generation Heat Mirror IG enables the next generation of energy-efficient windows.
