About Low-E Glass (see graphics below!)
With Low-E Glass in your new windows and doors, you will get the best comfort, beauty, and energy performance available. Low-E (Emissivity) Glass is a high performance, energy-efficient window glass made with an invisible coating that blocks heat flow. Showcase is proud to offer high performance Enviroshield Low-E glass.

How Does It Work?
Ordinary clear glass allows heat to pass through it. Heat always flows toward cold. The special coating on Enviroshield Low-E glass helps separate heat from cold.

In winter, heat stays inside where you need it to keep you warm. Enviroshield Low-E is 2-1/2 times better than ordinary clear glass at keeping heat inside in winter. In summer Enviroshield Low-E glass helps keep heat outside so you can stay more comfortable.

Because Enviroshield Low-E glass helps keep the inside glass warmer, you can enjoy a more comfortable humidity level. This greatly reduces condensation and fogging on your windows, thus reducing moisture damaging the interior of your home and the need to wipe off your windows and sills.

Keep Your Home Environmentally Friendly
Enviroshield Low-E glass is good for the environment. Every window installed with Enviroshield Low-E in place of ordinary clear single-pane glass reduces electrical demand and can save 250 gallons of oil over the life of the window.
