Low-E Glass


The glass contained in any of Window World’s exclusive SolarZone, SolarZone Elite Insulated Glass Packages is a Low-E glass, and a technological breakthrough that means your windows deliver unsurpassed performance and beauty. Low-E, or low-emissivity, glass is an excellent way to increase your home’s comfort and energy savings year-round.

All Window Worlds products with any of the optional SolarZone Insulated Glass Packages feature Low-E glass from SolarZoneTM

Low – E – Glass Features

Created by applying multiple layers of microscopic, undetectable metallic coatings to the surface of a piece of flat, annealed glass. The metallic coating helps block out the solar energy in the summer, while accepting and retaining warm, short-wave solar rays in the winter.

In the summer, Low-E glass filters long-wave solar radiation – reducing solar heat gain in your home as a result of the sun’s direct rays. In the winter, Low-E glass takes on two responsibilities: first it lets warm, short-wave rays into the home for natural warmth; then the Low-E glass helps block the warm air inside, rather than allowing it to escape through the pane, so your heating system runs less to maintain a comfortable temperature.


Why Low-E glass is right for you
