A Warmer Edge
Just as important as the glass itself is the spacer that seals the edges of the glass panes. E³-Max glass features the most energy efficient insulating glass spacer...Ultimate Warm-Edge Technology.

Inhibits Heat Escape Paths
The all-foam formula of the E³-Max Spacer System inhibits heat escape paths at the glass edge, providing one of the best thermal performances in the industry.

A quieter home...
Whether it's cars whizzing by, lawn mowers buzzing or inclement weather beating on your home, E³-Max's closed-cell foam spacer system transmits very little sound compared to conventional metal spacers, keeping noise outside your home.

Keeps moisture off the glass
The primary window condensation culprit is its insulating glass spacer. Traditional metal psacers can conduct heat and cold, causing condensation at the edge of the glass. Condensation can lead to bacteria and mold which can cause illness. E³-Max's Ultimate True Warm-Edge Techology helps reduce condensation and allows for comfortable household hmidity levels.

R-Value measures the resistance of a window to heat flow. A high R-value window has a greater resistance to heat flow and a higher insulating value than on with a low R-Value.

Note: The values listed above are the Center of Glass performance characteristics. These values are achieved by using software developed by the Lawrence Berkeley Laboratories. These values are the highest results achieved by E³-Max Glass using NFRC environmental conditions.
