In frigid temperatures, windows can become burglars, robbing your home of valuable heat. Typically, homes can lose 25 to 30 percent of their heat through windows. Larger windows and patio doors can increase the heat loss up to 50 percent!

No one wants to give up their windows, but you can reform them. HeatSaver Thermal Shades can stop this "thief" in the cold of night. HeatSaver Thermal Shades offer one of the most simple and cost effective energy conservation methods available for the savvy homeowner.

The economics:

• Heat gain and loss through windows and patio doors can account for 25 to 50 percent of your monthly heating or air conditioning bill. HeatSaver Thermal Shades effectively prevent 90 percent of this costly and unnecessary loss.

• Even thermopane windows only register an R-value of 1.87. HeatSaver Thermal Shades have an estimated R-value of 6.8, effectively increasing total R-values to nearly the equivalent of 3.5 inches of fiberglass insulation.

• Traditional blinds and draperies become brittle and deteriorate due to UV radiation, but HeatSaver Thermal Shades offer durability you can count on. Most shades will last 10 years, but some HeatSaver Thermal Shades are still functioning well after 20 years!

The science:

HeatSaver Thermal Shades operate on the principle of the Roman shade, using simple pull cords to raise and lower each panel. Durable clear polycarbonate track mounted on both sides of the window openings allows for smooth operation of the thermal shades, faciliating an effective perimeter seal when the shades are lowered.

The unique construction of HeatSaver Thermal Shades includes four components:

1) Thinsulate Thermal Insulation
Thinsulate, a product developed by 3M Corporation, is a proven and effective insulation product widely used in the sportswear industry. To compare: .65 inches of Thinsulate is as effective as two inches of down fill. Thinsulate is a 100-percent synthetic fiber material and sheds moisture well.

2) Aluminized Mylar
Two layers of aluminized mylar, one on either side of the Thinsulate core, reflect 97% of long wave heat radiation. Mylar also acts as a vapor barrier.

3) Polyester Lining
Our lightweight polyester lining will not deteriorate due to UV radiation or extreme temperature swings.

4) Interior Finish Fabric
While HeatSaver Thermal Shades can be finished with virtually any durable drapery material, the finish fabrics we stock have been chosen for extreme durability and ease of cleaning. 300-denier nylon treated with a water repellent and flame retardant are available at no extra cost in a variety of soft pastel and neutral colors.

The details:

HeatSaver Thermal Shades are a completely custom product, manufactured to your specifications and crafted entirely in the United States.

Unusual window shape? No problem. HeatSaver Thermal Shades can be made to fit even trapezoidal windows!
