Windows - which are about 80% glass - can be a significant source of energy loss on a home. You might think of the glass as being fragile, yet it's one of the most important elements in achieving super-efficient, weathertight performance. An exceptionally strong barrier, Amherst windows are expertly crafted with Energy HSG Low-E insulating glass utilizing double-strength glass and argon gas to increase thermal efficiency.
Energy HSG insulated glass units are built with the PPG Intercept Warm-Edge Spacer, which features a unique, one-piece metal alloy, U-channel design that helps block conducted heat loss through the windows. Its sealed, one piece-construction makes Intercept spacers stronger and better at retaining insulating gas than many conventional designs. Intercept is nearly 25% more effective than a traditional box metal spacer at the edge of the glass unit.
