Energy Savings with Lang Low-E Glass

Any Climate... Any Season... Regardless of where you live, Lang's Low-E glass options can help reduce the amount of money you spend and keep the inside temperature of your home comfortable.

Keeping The Warmth Inside Helps Minimize Heating Expense

Lang's Low-E coatings are designed to significantly reduce heat loss during the heating season. Windows and other glass enclosures are responsible for up to 35% of a home's heat loss. Controlling the heat loss means controlling your heating bills. Lang's Low-E glass works hard to put money back in your pocket by keeping the heat where you want it. These seasonably smart coatings allow the passage of the sun's warm solar energy into the home during the winter while preventing the heat inside from escaping. The result is a difference you can feel.

Due to the heat-reflecting properties of Low-E glass, the inside glass temperature of your windows will remain closer to room temperature. The result is a considerable decrease in the potential for condensation, or sweating, which can lead to water damage.

Keeping Solar Heat Outside Minimizes Air Conditioning Expense

As the seasons change, so do the criteria for comfort. With the arrival of summer or in predominantly warmer climates, the focus on energy efficient changes from heating to cooling - keeping the cool air in and the heat of the sun out. Due to the high trajectory of the summer sun, most solar energy is reflected off objects, such as trees, overhangs or the ground, prior to striking the windows of your home. This redirected or long-wave radiation is selectively rejected by the Low-E coatings. This translates into lower air conditioning bills and a more comfortable living environment.

Low-E products are also on guard protecting your furniture, carpets and other fabrics. By rejecting nearly all the damaging ultra-violet rays from the sun, Lang's Low-E glass keeps your furnishings looking like new, while allowing plant life to flourish.
