Solarban® 60 Low-E glass from PPG
Solarban 60 Low-E glass (low emmisivity) helps reduce energy costs in two ways. In summer, Solarban 60 helps block out long-wave radiation (direct sunlight) from the sun, keeping your home cooler. In winter, Solarban 60 helps retain furnace heat while allowing warming, short-wave solar rays to enter the home, putting less strain on your furnace to maintain a comfortable warmth.

Intercept™ Warm Edge Spacer from PPG
The Intercept Spacer System is designed to keep the edges of the window glass warmer. Even with insulating glass, if the edges are not sealed properly, the insulation of the window as a whole may be compromised. The Intercept spacer creates a “warm edge” seal for superior insulation and reduced likelihood of condensation at the edges of the window.

Insulating Argon Gas
Argon gas is a colorless, odorless, nonflammable, nontoxic, inert gas that is sealed between the two panes of glass. Heavier than air, and completely safe to humans and animals, the argon gas provides an additional layer of insulation, increasing energy-efficiency and also acting as a sound barrier to help deaden outside noise.
