What Is Low-E Glass?

Why does it put money in your pocket?

All HomeStar™ windows are available with the Low-E (or Low Emissivity) glass option.

Low-E has an invisible, metallic coating that admits the full spectrum of sunlight but blocks radiant heat from escaping.

In the winter 70-75% of heat normally escaping is reflected back into the home for energy savings. Low-E also increases the window's inside surface temperature, making the area near the window more comfortable.

In the summer 25% of unwanted heat is reflected back to the outside, helping to block ultraviolet light which would normally fade fabrics, carpet and furniture.
