Insulated Glass

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.

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.

Many window manufacturers provide LoĒ² glass in their standard configurations. Please contact your window supplier, builder or architect on how to obtain LoĒ² glass in your next window purchase.
