Insulated drapes are multi-functional. They help insulate the windows in your home from heat loss in the winter and they keep heat out in the summer. They are an easy way to reduce heating and cooling costs by making your home more energy efficient. The windows in your home are the number one source of heat loss.
Insulated drapery should by no means be used in place of double glazed windows. They can be used to enhance the energy saving qualities of double glazed glass. They can also serve as blackout drapes because they block out light completely.
