    Recent times have seen increased demand for energy efficient products in the United States. As a result of environmentally concious initiatives such as the LEED™ Green Building Rating System, windows are playing an increasingly vital role within a building’s envelope. With this in mind, Keystone’s engineers have designed the KI7000 SYSTEM to challenge the current perceptions of thermal performance in aluminum windows.

    The KI7000 SYSTEM utilizes these energy efficient systems to their fullest, including a European styled structural thermal barrier which is superior to the poured & debridged thermal break common in most North American windows.

KI7000 windows have achieved remarkably low U-Values (as low as .32 with certain glazings), earning the ENERGY STAR® for all climate zones in the U.S.
