ClimaGuard Low-E High Performance Glass is the latest in a long line of innovative products. In fact, the more you know about ClimaGuard Low-E, the more you’ll be convinced of its superior capabilities.
The environment is not your friend. It has a tendency toward dramatic fluctuations throughout a single day — not to mention throughout an entire season. ClimaGuard Low-E actually goes to work, regulating your interior environment every day, every hour, in every season — unlike "standard" glass (which really just sits in a window passively). That’s the beauty of the world’s most advanced low-E glass.
Our scientists have improved the insulating value of ClimaGuard Low-E Glass by as much as 50% over standard clear glass – resulting in significantly lower energy costs when heating your home. With ClimaGuard Low-E, even the coldest regions can enjoy the view with little or no impact on energy consumption.

When using ClimaGuard Low-E Glass, solar heat gain and damaging radiation can be significantly reduced without sacrificing clear views and daylight. ClimaGuard Low-E blocks up to 50% more unwanted solar energy than standard clear glass, and up to 40% more than even dark tinted glass. As a result, air conditioning expenses are lowered while providing a more comfortable living environment. ClimaGuard Low-E also blocks nearly twice as much harmful radiation as clear glass, extending the life of woodwork, carpets and furnishings, while still allowing plenty of natural sunlight to brighten interior spaces.
In mild climates or in climates that enjoy mild seasons, southern and western elevations of a home can be exposed to significant unwanted solar heat gain. The result is a higher temperature in rooms that are exposed to the sun, while the rest of your home and the air outside remain at a comfortable level. ClimaGuard Low-E Glass greatly reduces this effect and helps maintain a uniform comfort level throughout your home.
