Basics Of Low-E Glass
Low e glass uses a coating on the exterior of the glass pane that lets in long wavelengths (sunlight) and reflects short wavelengths (heat). Low-e glass coatings are made from metallic particles and should not be confused with a tinted glass that simply changes the color of the glass. The density and consistency of the low-e e coating can change how much sunlight and/or heat is allowed through the pain.
Window manufacturers can use one or more coats on a single low E glass pane. They may also alter how the layers are stacked on top of one another to affect how the glass will behave. Finally, they can add tinting to the layers to affect certain change. These different variables can affect the amount of light let in, the amount of heat let in, the amount of UV rays and more.
