CHOOSING THE PROPER GLASS FOR YOUR PROJECT
For the Maximum in Comfort LoĒ²-272®
Whether it is 20 below or 110 in the shade, you can bring year-round comfort to your home with The Window Design Group Company's LoĒ²-272® glass. In winter, LoĒ²-272 reflects heat back into the room. In summer, it rejects the sun's heat and damaging solar rays. Additionally, it is the clearest, highest performing glass you can buy – without haze or a bluish cast.
Hot or Cold Outside, Comfort Inside
The insulating effect of your windows has a direct impact on how your rooms feel. Typically, 75% of the exposed surface of a window is glass, and the temperature of the room-side of the glass directly affects the air temperature in the room. Therefore, the better insulated the window glass, the warmer your room will be.
The American Society of Heating Refrigeration and Air-Conditioning (ASHRAE) Comfort Standard 55 suggests that when glass surface temperature fall below 52º F, the result is thermal discomfort. In order to maintain comfortable temperatures during the winter, LoĒ²-272 glass produces surface temperatures that will stay above this point during the coldest outdoor conditions.

Solar Control with the Coolest Windows Under the Sun
Windows made with clear glass or ordinary low-E glass can be the biggest offenders when it comes to the air-conditioning load in your home. When it's hot outside, the sun comes raging in making your house uncomfortable. This high solar heat gain can contribute to more than 50% of air-conditioning costs.
LoĒ²-272 blocks enough solar heat that cooling loads can be cut by 25% or more compared to ordinary low-E and clear glass. Controlling solar gain not only saves energy during the air-conditioning season, it also improves the comfort and livability of sunny rooms during the spring and fall when the cooling system isn't normally used.
The oppressive heat of the sun is composed of visible light and invisible infrared energy. LoĒ²-272 is produced with a patented coating technology that allows the daylight to pass through the glass and filters out solar heat. In fact, it blocks 84% of the sun's harmful ultraviolet rays and delivers a remarkable 96% performance improvement in winter nighttime insulation (R-value) compared to non-coated air-filled insulating glass.
This translates to comfort and substantial energy savings.
Think of it as Invisible Insulation
The insulating value of LoĒ²-272 is nearly double that of an ordinary insulating glass unit, or the equivalent of a quad-glazed window!
LoĒ²-272 even outperforms the tinted glass often used in warm, sunny climates. You see out and the light shines in, with no heavy bronze or smoke-colored tints to darken the personality of your home.
Really, no matter what it is like outside, you can count on LoĒ²-272 glass to comfort you and your loved ones on the inside – all year long.
