The changing seasons can wreak havoc on your energy bills! This is why the Park Avenue^® Window Collection uses state-of-the-art insulating glass technology...The E³-MAX^® Triple Pane Glass System.

This superior triple pane insulating glass system features Dual Soft-Coat Low-Emissivity Glass, one light of annealed Float Glass and Krypton Gas charged chambers.

The E³-MAX^® Triple Pane Glass System teams with the Ultimate True Warm-Edge Spacer System to reduce the transfer of heat and cold along the edge of the glass. This powerful combination boasts a Center of Glass R-Value of 9 and results in driving lower utility bills and creating the most comfortable environment possible for your home and family.

E³-MAX^® Triple Pane Glass System also blocks 96% of the harmful UV rays that can fade and damage your home furnishings. Distracted by the noisy bustle of the outside world? Triple pane windows like the Park Avenue^® Window with E³-MAX^® Glass reduces outdoor sound to quiet your home's environment.

Park Avenue windows and patio doors incorporating our high performance E³-Max^® low-emissity and krypton enhanced glass system qualify for the ENERGY STAR^® label. Park Avenue ENERGY STAR labeled products lower your heating and cooling costs and make your home a more comfortable environment.

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.
