What’s a Low-E Window?

A low-e glass window (which stands for low emissivity) is simply a windowpane coated in microscopic layers of metallic oxides. The coating appears invisible to the naked eye, allowing as much natural light into the house as possible. However, though transparent, this coating also protects your home from unwanted UV rays which can burn your skin, fade your carpets, and damage your furniture. Plus, it also helps to control radiant heat (infrared light) as it enters and leaves a room. In other words, it keeps your house warmer in the winter by reflecting certain segments of the sun’s light spectrum back into the home, and cooler in the summer by reflecting particular sections outside. This saves on unnecessary utility expenses while creating a more comfortable living environment.
