Vinyl replacement windows by CertainTeed

Energy efficiency information on patio doors and vinyl replacement windows

All objects emit energy as some form of radiation. Heat from a furnace, or even a person, is "long wave" radiation. Light from the sun generates "short wave" radiation. Thermaflect knows the difference.

In cold weather, you spend your energy dollars generating long wave radiation. That heat moves toward your cooler windows, but Thermaflect acts like a mirror, reflecting it back inside to save you money.

Thermaflect maximizes the beneficial energy of the sun. The coating selectively transmits the visible light (short wave energy) from the sun into the room, while reflecting away the ultraviolet radiation that can damage curtains and upholstery.

The short wave energy is then absorbed by objects such as sofas, carpets, even people, and is radiated from them as long wave heat. Thermaflect acts like a shield to this heat, preventing most of it from passing back out the windows!

What's more, Thermaflect glazing with low conductance spacing is 10% warmer, saves 5% more heat, and reduces condensation up to 80%; so the room is more comfortable all around.

The total result for you is a better living environment and lower heating costs.

Thermaflect works hard for you in hot weather.

Where vinyl replacement windows are exposed to direct radiation, Thermaflect's (Heat Mirror) unique multi-layered coating blocks unwanted ultraviolet radiation and reflects away infrared radiation that can add heat to the inside of your home.

In some locations in summer, the sun is at a higher angle in the sky and less likely to stream directly into your window. Also, roof overhangs, trees, and tall shrubs serve to deflect sunlight from some windows, shield the more frequent use of blinds, drapes, and other window treatments also helps block unwanted heat. But you still benefit from Thermaflect.

Sunlight becomes long wave heat radiation when it is absorbed by things outside such as your driveway, shrubbery, or patio. Thermaflect acts a a shield to prevent this heat from entering your home through the windows, so your air conditioner does not have to work overtime.

With Thermaflect, you stay comfortable and your cooling costs stay lower - without sacrificing sunlight.
