Low-emissivity coatings on many ENERGY STAR certified windows, doors, and skylights reduces UV sun damage to floors, carpets, and furniture.

Get Comfortable Comfort. Its the essential quality of home. ENERGY STAR certified windows, doors and skylights do more than just lower energy bills. They deliver comfort that other products just cant match.
On cold winter nights, do you avoid seats near the window? The cold, inside surface of an inefficient window pulls heat away from your body, so you can feel chilly in a sweater with the thermostat at 70 degrees. With ENERGY STAR certified windows, the interior glass stays warmer, so you can enjoy your window seat even when the temperature outside dips well below freezing.
Do some of your rooms feel like a sauna in the summer? A standard double-pane window allows approximately 75 percent of the suns heat into your home. With ENERGY STAR certified windows you can stay cool all summer long. Most ENERGY STAR certified windows reduce the heat gain into your home more than typical windows do, without reducing the visible light. You get the light you need without the uncomfortable heat.
Drapes, wood floors, a favorite photograph: all these things can fade or discolor after repeated exposure to direct sunlight. Whether their value is monetary or sentimental, you want to protect your belongings from fading and discoloring. ENERGY STAR certified windows have coatings that keep out the summer heat and act like sunscreen for your house, protecting your valuables from harmful, fading ultraviolet light without noticeably reducing visible light. These special coatings reduce fading by up to 75 percent.
