Let's first consider some arresting numbers: 40% of the heat that escapes from your home leaves through the windows. And 50% of the solar heat that enters a room comes in through—you guessed it—the windows. Obviously, energy efficient treatments can translate into considerable utility bill savings, especially if your windows are on a cold north exposure in the winter or a sun-saturated west wall in the summer. The most energy efficient treatments feature a honeycomb construction. The cells actually trap the hot or cold air, decreasing the intensity of the temperature as it enters the room. A honeycomb shade with a triple cell construction will increase the energy efficiency of a single pane of glass by five times and more than double the energy efficiency of a double-glazed window. |
