ClimaGuard® Low-E High Performance Glass is a family of innovative products designed to save energy. The more you know about ClimaGuard Low-E, the more you’ll be convinced it is the right energy-saving glass solution for you. Increasingly, both window makers and consumers agree that a window system featuring Guardian glass combines performance and efficiency. Window makers get a business partner that is steadfast, innovative and reliable. Consumers get access to a diverse network of window makers committed to excellence.
The environment can be a fickle friend. It has a tendency toward dramatic fluctuations throughout a single day — not to mention throughout an entire season. ClimaGuard Low-E Residential Window Glass helps regulate the interior environment every day, every hour, in every season - unlike "standard" window glass which really just sits in a window passively. That’s the beauty of the world’s most advanced low-E glass.
Perhaps most important to window manufacturers and consumers alike is glass that is designed for the future: from advanced coatings and innovative spacer technology to vacuum insulating glass (VIG), Guardian sees years ahead.
Our glass experts have improved the insulating value of ClimaGuard Low-E Window Glass by as much as 50% over standard clear window glass – resulting in significantly lower energy costs during heating. 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 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.
