Cardinal LoĒ²-240 Glare Control Glass

Glare Control Glass - Dallas Fort WorthLoĒ²-240® glass provides a great combination of aesthetic appeal along with energy savings and indoor comfort. This cool, spectrally selective coating is applied to clear glass, so that the appearance and performance are the same regardless of glass thickness. LoĒ²-240 is more than a solar control glass. Its advanced coating design also provides the lowest possible U-factor to deliver comfort and energy savings during cold winter weather. What makes multi-layer LoĒ²-240 different is its ability to handle each portion of the solar spectrum differently, making it spectrally selective.

Cardinal LoĒ²-270 All Climate Solar Control Glass

Solar Climate Control GlassEvery day, the sun provides an enormous amount of energy. In colder climate areas, this energy is beneficial and welcomed for warming homes. But summer temperatures throughout the U.S. can reach a blistering level and bring discomfort into the home. Since the majority of solar heat gain comes through your windows, choosing the right glass can be a key factor in comfort and year-round energy savings.

Cardinal CG Company’s LoĒ²-270® glass is the perfect glass for all season comfort. It reduces solar heat gain by 50% or more when compared to ordinary glass. Although it is a clear glass, LoĒ²-270 even outperforms ordinary tinted glass typically used in sunny climates. And though it’s coated, LoĒ²-270 lets the light shine in to warm your house during the cooler winter months.

Low-E Glass Advantages

Low-E Glass Advantanges

Because it resists ultraviolet light, low-E glass prevents sunlight exposure from damaging carpets, draperies, sofas and other furnishings. Plus, low-E glass reduces sunlight glare in a room. Most importantly, low-E windows reduce energy costs by helping to control the climate in the house. Low-E glass allows sunlight into a room without letting heat inside. In the summer this keeps rooms cool and lowers air conditioning costs. If you’re ready to replace your windows with new low-E glass windows, contact J.J.’s Window Service.
