This means that up to half of what is paid for heating and cooling utility bills pours through them, as well.  Isn’t it time to stop throwing money out the window?

Here are three ways to save energy:

Installing energy efficient window treatments in your home can reduce heating, cooling and lighting energy needs in these significant ways:

Reduce heat flow (heat loss and heat gain) through the windows.

Control solar heat (heat energy from the sun) by allowing it in winter but reducing it in summer.

Enhance day lighting (the use of natural light) by diffusing and dispersing sunlight deep into a room.
