Energy Efficient Glass

Maintaining a comfortable indoor environment is a challenge when temperatures fluctuate, sometimes dramatically, throughout the day, between seasons and across climate zones. According to U.S. Government estimates, an average household spends more then 40% of its annual energy budget on heating and cooling.

Keeping you warm when it’s cold outside.

Using our glass can result in significantly lower heating energy costs and an improvement in insulating value of as much as 50% over standard clear glass. In cold regions, this means that windows are no longer an energy loser.

Keeping you cool when it’s hot outside.

With our glass, solar heat gain and damaging radiation can be significantly reduced without sacrificing clear views and daylight. Our glass blocks up to 50% more unwanted solar energy than standard clear glass and up to 40% more than dark tinted glass, resulting in lower air conditioning expenses and a more comfortable living environment. Our glass 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 up interior spaces.
