What kind of energy efficient glass do you offer in your Grandview series windows.

First of all, every 7/8″ insulated glass unit uses Warm-edge Intercept spacers. Warm-edge intercept is one continuous piece creating a stronger, more energy-efficient insulated glass unit. Plus it flexes with glass expansion and contraction to ensure a strong seal for the life of the window. The Grandview window offers 4 levels of insulated glass ranging from dual pane clear glass without Argon gas to triple pane glass with 2 layers of  soft coat LowE with Argon fill. All of our glass units, with the exception of the clear glass option are Energy Star approved.
