Manufacturers now offer Low-E window replacements with special coatings designed for hot regions such as Florida that let in 40 percent less solar heat. Less heat enters the house through the glass, so the house can get cooled easier and faster.

What is Low-E?

Anytime you see Low-E on a replacement window it means a "low emittance" coating was placed on the window. This microscopically thin coating is made from metal or metal-oxide layers that are glazed on the surface of the window. The goal is to reduce and block infrared light, IR, (the light which causes heat) and ultraviolet light, UV, (which can cause floors and furnishing to fade colors).
