State Of The Art In Performance Technologies

Cooler In The SummerThe total solar energy transmitted through SlocombHigh Performance Low-E Glass is almost 63% lessthan that transmitted by standard clear insulatingglass.• Lower SHGC numbers mean less summer heat• Keeps interiors cooler• Helps reduce cooling energy cost

Reduces Ultraviolet EnergySlocomb High Performance Low-E Glass reducesfabric-fading UV energy 90% more effectivelythan standard clear insulating glass.• Helps protect interior furnishings, fabricsand carpets from fading

Transmits Visible LightSlocomb High Performance Low-E Glass transmitsabout 80% as much desirable visible light asstandard clear insulating glass.• Provides exterior appearance similar toclear glass

High Performance Low-E Glass

Be Comfortable With Your Energy BillThe high energy performance of Keystone windows have the combined fac-tors of a Warm Edge spacer and High Performance Low-E glass. Combinethese technologies with an Argon gas fill and you will maximize your energyperformance and decrease your heating and cooling costs. In the wintermonths, Low-E helps keep heated air inside and cold air outside. In the sum-mer, Low-E helps keep cool air in and hot air out. Low-E also blocks up to84% of the harmful ultraviolet rays which can fade carpets, draperies and art-work. In addition since Argon gas is six times more dense than air, it greatlyreduces the transfer of hot and cold-adding even more thermal efficiency. It isthis combination of Warm Edge and Low-E/Argon filled glass that helps yousave on your heating and cooling costs.
