High on your list for low heat gain

Excellent light transmission is possible without the heat that usually comes with it. SunGuard® SuperNeutral® (SN) 70/35 is a neutral blue glass that offers solar protection while reducing the need for artificial light. Ideal for fully glazed facades and large frame windows, SN 70/35 combines excellent solar protection with outstanding thermal insulation.
