It is a scientific fact that heat is attracted to cold. In winter months, indoor heating moves toward and escapes through windows to the outdoors, while in the summertime, the outside heat flows into your home through these same windows. Without energy-efficient window treatments, as much as 50% of a home’s heating and cooling energy can be lost through windows. Many window treatments help insulate homes so you can reduce energy consumption, save on heating and cooling costs, and create a more comfortable room setting.
