LoE-180

 

Welcome home to comfort.

When the weather turns frigid, Cardinal LoE-180 glass is the perfect cold remedy. It keeps homes warmer and more comfortable by blocking heat loss to the outside and letting the sun’s heat stream in. With a glass U-Factor of just 0.26 and an SHGC of 0.69, LoE-180 is the ideal product for passive solar applications. It extends a warm welcome home while achieving the highest ER values.

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 – choose Cardinal LoE-180, the ideal choice for passive solar designs.

 

When it’s freezing cold outside, it’s cozy inside.

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.

The table below compares the room-side center of glass temperatures of different glass types against two different winter conditions.

The superior insulating capability of Cardinal LoE-180 is a key factor in the construction of comfortable windows for cold climates. The dramatic comfort improvement from windows with warm glass surfaces also means the relative humidity of the indoor air can be controlled and maintained properly. Proper humidity levels (not too much, not too little) will improve comfort and promote a healthier living environment.

 

Blocks out the cold, lets in the light.

Cardinal LoE-180 delivers outstanding cold weather performance – its insulation value is excellent with a low 0.26 U-Factor. And with an SHGC of 0.69, it lets the winter sun’s heat pass into the home. It also blocks 71 percent of the sun’s harmful UV rays. While blocking out the cold and UV rays, it lets the daylight stream in – more light than ordinary low-e glass.

Our unique coating is the key.

Cardinal employs a state-of-the-art sputter coating process that is unmatched by any other glass manufacturer. The glass is coated with a microscopically thin, optically transparent layer of silver sandwiched between layers of anti-reflective metal oxide coatings. A protective coating is applied to assure durability and long life. The coating is virtually invisible to the eye – it’s just like looking through clear glass.

 

Save energy with glass so smart, it can control your comfort.

Although windows provide beautiful views and wonderful natural light, they can also account for up to 50% of the heating and cooling energy consumed in a home. In the winter, Cardinal LoE-180 helps your home stay warm and cozy by blocking heat loss to the cold weather outside. Summer solar gain is about 10% less than ordinary double pane clear glass and the low U-Factor blocks heat gain from the hot weather outside. In short, it can save energy year around.

 LoE-272:

 

Who says you can’t do anything about the weather? Cardinal LoE-272® glass delivers year-round comfort in all types of weather. In winter, it reflects heat back into the room. In summer, it rejects the sun’s heat and damaging UV rays.

Cardinal LoE-272 is very similar to our LoE-270® glass, only with a little more light transmittance, while LoE-270 offers slightly more solar control.

 

Cold or hot outside, Cardinal comfort inside.

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 that decision. Go beyond ordinary low-e glass.

Let LoE-272 help you handle the weather – any weather.

 

Frigid outside, cozy inside.

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 (www.efficientwindows.org) suggests that when glass surface temperatures fall below 52°F, there is a risk of thermal discomfort. To maintain the best comfort during the winter, select a glass product that produces surface temperatures that will stay above this point during the coldest outdoor conditions.
