Cardinal Coated LoE Glass


Regardless of where your home is located, choosing windows that provide you with the highest level of comfort and energy savings year-round is extremely important. And choosing the right glass for your windows is the most important factor in the decision. Go beyond ordinary low-e glass.


LoE glass reflects heat back into a room in winter and rejects the sun's heat and damaging solar rays in summer, increasing comfort, decreasing energy costs, protecting against fading of interior furnishings, and reducing condensation.


LoE2 272


Hot or cold outside, who says you can't do anything about the weather? Cardinal LoE2 272 glass delivers year-round comfort, whether it's 20 below or 110 in the shade. In winter, LoE2 272 reflects heat back into the room. In summer, it rejects the sun's heat and damaging UV rays. Not only is it the clearest, highest performing glass you can buy, there's no haze or bluish tint.


The coating is virtually invisible to the eye, yet blocks 84% of the sun's harmful ultraviolet rays. In fact, LoE2 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.


During cold weather, 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. The better insulated the window glass, the warmer your room will be. In fact, the Efficient Windows Collaborative ( suggests that when glass surface temperature falls below 52 degrees Fahrenheit, there is a risk of thermal discomfort. To maintain the best comfort during the winter, select a glass product that provides surface temperatures that will stay above this point during the coldest outdoor conditions.
