Earning the ENERGY STAR

• ENERGY STAR qualified windows, doors, and skylights can help reduce your utility bills up to 15%.

• ENERGY STAR qualified window products also provide protection against sun damage to fabrics in your home.

Remember, saving energy prevents pollution.
To achieve maximum energy and pollution savings, keep these things in mind when shopping for windows:

1. Window products are tailored to fit the energy needs of the country's three main climate regions: Northern, Central, and Southern.

2. Window performance is based on the following factors:

   • U-factor: The rate of heat transfer either from your home or the outside through your window, door, or skylight. A lower U-factor means less heat is transferred.
   • Solar Heat Gain Coefficient (SHGC): How much heat your house gains from the sun. A lower SHGC results in less heat gain from the sun.

3. All ENERGY STAR qualified window products also bear a label from the National Fenestration Rating Council (NFRC), which provides independent energy performance ratings by product for U-factor, Solar Heat Gain Coefficient, and Visible Transmittance.
