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.
