Energy HSG Glass Package

Windows are about 80% glass.

This 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.

Energy HSG Glass Package

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 Glass Package


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.

The 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. 

Designed to meet the rigors of cold Canadian northern climates, our specially formulated Energy HSG glass system maximizes the advantages of solar heat during the winter.
