What Is Low-E Glass?
We hear a lot about Low-E glass these days. But what is Low-E glass and how does it work? To properly answer the question about what is Low-E glass we really need to talk about the solar energy spectrum or the energy from the sun.
UV light – This is the light that causes your furnishings, floors, and artwork to fade.
Visible light – This light is the light that is visible to the human eye.
IR light – Infrared light is transmitted as heat.
Now that we understand the different lights let’s go back to Low-E coatings. Low-E coatings have been designed to cut down on the amount of UV and infrared light that is transmitted through glass. This very thin Low-E coating that is applied to the glass reflects long wave infrared energy, or energy that is coming from the sun.
Low-E glass is great because it helps block out some of the heat from the sun without loosing any visible light. If you don’t have Low-E windows but would like to have the benefits of Low-E glass, you can have window tint installed and it will accomplish the same or more, depending on the tint selected.
