Low E windows, E standing for emissivity, are considered the most efficient windows due to their ability to reflect heat. The glass is covered with a thin metallic substance that reflects heat, helping improve the climate control in the home. While this makes sense during a hot summer, does it also work in the winter? The quick answer is yes, but only if you have a contractor that installs them correctly.
It may seem that low E glass would be counterproductive in the winter. If it reflects the sun, it also would reflect the heat that can be gained when trying to warm your home. However, there are different types of low E windows and different options for installation. For those that have cold winters, considering a lower U-factor is also important, which helps keep heat in, on top of low E windows. For installation:
Low E windows can be beneficial, allowing light in, but reducing lost cool air during the summer and lost warm air during the winter. However, it is just one of several factors to consider when installing new windows. U-factor. SHGC, VT and CR are other considerations when picking your new windows. Talk to your contractor to learn more about what all these options mean and to determine the best windows for your home’s energy efficiency.
