When it comes to windows, the type of glass you choose is extremely important. Most experts estimate that 70% of a home’s energy loss occurs around windows and doors. Even more astonishing is the fact that 90% of window heat loss occurs through glass. We all know that energy efficiency is important but understanding your window can be very confusing when researching different types of energy-efficient glass. Let’s take a look at what a Low-E (LoE) window is, how it can help save you money, and the different types of LoE coatings.

What is Low-E Glass?

LoE, or low-emissivity, glass helps reduce the amount of infrared and ultraviolet light coming through your glass, without affecting the amount of light that enters your home. LoE glass windows have the thinnest coating that is virtually transparent and will reflect heat. In fact, the coating is even thinner than the hair on your head! The LoE coating will help keep a consistent temperature in your home by reflecting the temperatures back inside.

Types Of Low-E Glass

Elite Windows and Doors is proud to carry Cardinal Glass LoE glass in three varieties. Let’s break down the differences between each.

  1. LoE-180 Glass: As the weather turns colder each winter, LoE-180 glass is a great perfect remedy. This glass will keep your house warm by keeping the warm air in while also letting the sun’s rays stream in. No matter what climate you live in, choosing LoE-180 will provide the highest level of comfort while saving you money through energy efficiency.
  2. LoE-270: The sun provides an enormous amount of energy daily. In colder climate areas, this energy is beneficial and welcomed for warming homes. But, throughout the U.S., summer temperatures can reach scorching levels, making your home uncomfortable. The majority of solar heat gain comes through your windows, so choosing the right glass is important when it comes to comfort levels and year-round energy savings. LoE²-270 glass is the perfect glass for all-season comfort. It helps reduce solar heat gain by 50% or more when compared to ordinary glass. LoE²-270 outperforms ordinary tinted glass typically used in sunny climates, even as clear glass. Although it’s coated, LoE²-270 lets the light shine in to warm your house during the cooler winter months. Remember, Cardinal’s LoE² coatings reduce not just interior discomfort, but also annual energy costs.
  3. LoE-366: This level delivers the ideal balance of solar control and high visibility. And it provides the highest levels of year-round comfort and energy savings. It’s also the one glass you can use to be compliant in every ENERGY STAR zone – in a double-pane window. When the temperature soars, ordinary window glass just can’t handle the heat. And tinted glass spoils the view. Cardinal LoĒ³-366, however, has been specially formulated to reject the sun’s heat without affecting the view. It lets more light in and keeps more heat out. So, your home stays cool and comfortable. During the cold weather, the insulating effect of your windows has a direct impact on how your room feels. The better insulated the window glass, the warmer your room will be!

Whether you are deciding on the window style, size, or design for your home, it’s also very important to take the time to consider which type of glass would work best.
