Heat Mirror IG

Heat Mirror technology from Eastman Chemical Company creates multiple insulating spaces—without adding weight—that buffer against heat loss or heat gain by suspending from one to three clear films in the airspace of insulating glass. The result is center-of-glass thermal performance of up to R-20 (U-value down to 0.05)—insulation that equates to a typical wall. 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.
