Low-E Coating and Argon Gas save on energy and reduce interior fading.
Low-E (low emissive) coating is a thin, metallic film that is practically invisible to the naked eye. Argon Gas is a harmless, odourless, colourless gas from natural sources, with a higher insulation value than air. Together, they make your home cooler in the summer, warmer in the winter and they reduce the harmful ultra-violet rays that can fade your interior surfaces. The insulating values of this popular Low-E Argon combo also reduce fuel consumption – good for the wallet and good for the environment.
Make double-glazed sealed units perform like triple-glazed.
Low-E coating forms a barrier to long-wavelength energy only. The sun's rays are short-wavelength radiation and easily pass through the window while the longer wavelengths of more harmful U-V rays are significantly reduced. Much of this solar energy is absorbed into the structure and furnishings, but the rest is re-radiated inside the house as long-wavelength energy.
Your heating and cooling systems also make long-wavelength energy. Uncoated glass absorbs most of this long-wavelength energy and re-radiates it to the outdoors. Low-E coating significantly reduces that thermal loss. The smaller amount of re-radiated energy that does make it out through the interior coated glass is then impeded by the Argon Gas inside the unit to help keep you warmer in the winter and cooler in the summer. Please note that Low-E Coating is not available in some decorative glazing. Ask for details.

Norwood introducing innovative glass solutions for the home by Guardian ClimaGuard ®
ClimaGuard® 71/38 residential window glass blocks nearly twice as much harmful UV rays as clear glass, extending the life of woodwork, carpets and furnishings, while still allowing plenty of natural sunlight to brighten interior spaces.
ClimaGuard IS Low-E glass products are engineered to have the one characteristic window manufacturers and homeowners need most - lower U-values. Designed to be used on the interior surface of double- glazed or triple-glazed windows with Low-E, ClimaGuard IS glass will provide a lower U-value to increase comfort and improve energy savings.
ClimaGuard IS-20 can help many windows meet new energy codes & ENERGY STAR® standards without the need for argon gas.
Valuable furnishings, draperies, rugs and hardwood floors don't have to suffer damage and fading from UV rays as a penalty for the health benefits and enjoyment of a room flooded with natural light.
Norwood continues to offer the ClimaGuard SPF option: complete UV protection without sacrificing the sun.
For more information on how can protect your valuable floors and furnishings, while still allowing plenty of natural light, talk to a Norwood representative.
