How low-e works

Low-e glass has an almost invisible coating contained on the inside pane of an insulated glass unit (IGU). This coating lets the sun’s light and energy into your home and reflects heat back indoors, forming a shield against the cold. It cuts heat loss by about 20% to 30%, compared to double glazing without low-e*. In warmer climates low-e glass can also be used to keep cool air inside your home.

Why choose low-e?

Low-e makes your home more liveable. And if you add an insulating gas like argon to your double or triple glazed unit, it will keep in even more warmth. And as part of a total window system, low-e can help boost the energy efficiency of your windows and help you achieve an ENERGY STAR mark for your home.
