The clear choice, no matter where you live.

Unlike many glass products on the market today, Cardinal LoĒ²-172 is the one clear choice. With our patented coatings and superior energy ratings, LoĒ²-172 delivers the clearest, highest performing glass available today. From cold winter nights to hot summer days, you will enjoy viewing the great outdoors from the energy efficient comfort of your home. And, because LoĒ²-172 glass blocks most of the sun’s damaging ultraviolet rays, it will help your curtains, carpets, furniture and wall coverings stay beautiful for years to come.

Window glass that can control the weather.

Although windows provide beautiful views and wonderful natural light, they can also account for up to 30 percent of the annual energy consumed in a home. Cardinal
LoĒ²-172 glass is designed to provide you with year-round savings and comfort by optimizing both the sun’s heat and your home’s heating and cooling systems. In the summer, LoĒ²-172 keeps your home cool and comfortable by rejecting the sun’s heat and damaging rays. In the winter, LoĒ²-172 helps your home stay warm and cozy by reflecting heat back into the room.

Think of it as invisible insulation.

Cardinal’s LoĒ²-172 blocks 84 percent of the sun’s harmful ultraviolet rays and delivers a remarkable 96 percent performance improvement in winter nighttime insulation (R-value) compared to non-coated air-filled insulating glass. However, it is virtually invisible to the eye –- just like looking through clear glass. In fact, LoĒ²-172 is the clearest, highest performing glass you can buy; there’s no haze or bluish cast to mar your view. LoĒ²-172 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.

All around comfort, all year long.

If you live in a climate where you heat and air condition, Cardinal LoĒ²-172 is the best choice you can make. It provides you with unhindered views, substantial savings on both heating and cooling bills and year-round comfort. In addition, many utility companies are now offering rebates for energy efficient window products like LoĒ²-172.
