LoĒ-180 Glass

Freezing cold outside, Cardinal comfort inside.

When the weather turns frigid, Cardinal LoĒ-180™ glass is the perfect cold remedy. It provides excellent insulating capability, even better than our previous high solar gain glass, blocking heat loss to the outside and reflecting heat back into the room. What’s more, it’s the ideal glass for passive solar applications because it allows the winter sun’s heat to pass into the home.

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 LoĒ-180, the ideal choice for passive solar designs.

LoĒ-180 makes it 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 four different glass types against two different winter conditions.

The superior insulating capability of Cardinal LoĒ-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 sun’s heat and light.

Cardinal LoĒ-180 delivers excellent cold weather performance – its insulation value (U-factor) is a low 0.26, and with a solar heat gain coefficient (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.

Visible Light Transmittance

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.

Count on LoĒ-180 to always meet or exceed expectations

Cardinal I.Q. (Intelligent Quality Assurance Program) ensures the quality of every piece of glass. Using our own patented inspection systems, we thoroughly examine the glass from start to finish.

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

ENERGY STAR compliant in most of northern North America

In conjunction with an efficient window frame design, LoĒ-180 can comply in the Northern zone of U.S. ENERGY STAR. The combination of high solar gain and excellent insulating value allows LoĒ-180 to achieve one of the highest ER values for a double-pane glass in the Canadian window rating program. Many of these double-pane windows can then achieve Canadian ENERGY STAR compliance as far north as zone C.

Glass Performance

Think of LoĒ-180 glass as invisible insulation. Although windows provide beautiful views and wonderful natural light, they can also account for up to 25% of the annual heating cost for a home. In the winter, LoĒ-180 helps homes stay warm and cozy by blocking heat loss to the cold weather outside while welcoming the sun’s heat inside.

LoĒ-180 can be purchased in a variety of custom shapes and sizes. To learn more about it and other Cardinal glass products, ask your contractor or architect.
