If you have been researching replacement windows for your home, you have probably read something about windows that are made with something called “low-e glass.” Many window manufacturers toss around the term low-e pretty casually. But it is actually a very important factor in making your new windows energy efficient.
The “e” in low-e glass stands for emissivity, which is the relative ability of a surface to emit energy. Believe it or not, low-e glass is actually coated with an ultra-thin metal layer. The metal is so thin that you can see through it, but it still performs the role of reflecting or absorbing energy. The thickness of the coating and the position of chemicals in the window glass itself also contribute to how well low-e glass does its job of reflecting energy.
The energy that is reflected by low-e glass is both heat and light energy. In addition to visible light and UV light, sunlight contains infrared (IR) light. Infrared light is what you feel as heat. Low-e glass has the ability to block certain levels of IR light, as well as harmful UV rays.
Now you are asking how a window coated with metal can help reduce your home energy bills. Here’s how.
When IR light enters your home, it raises the temperature whatever it touches. Low-e glass reflects this energy, keeping your home cooler in the hot summer months. The reverse occurs during the cold winter months. The low-e glass keeps heat from escaping to the outside by reflecting the heat energy back into your home. So your home heating system has to work less often to keep your home warm, using less fuel (oil, gas, electricity) and cutting your monthly bills.
The heat reflecting properties of low-e glass will help keep your energy costs down all year long. Which is why investing in replacement windows with low-e glass is a smart move.
