In environments such as southern and central Arizona, including Phoenix, replacement windows can certainly make a noteworthy difference in the comfort level of your home and in your utility bills. In addition to the benefits associated with energy and money savings, energy efficient replacement windows also improve the appearance of a home, make it quieter, allow less dust to come in a home, preserve the interior (carpet, rugs, floors, furniture, window coverings, art, pictures) from fading caused by ultraviolet light, allow more light in and cut down on condensation on the windows.

Window Ratings
With in excess of 300 days of sunlight in a year, how effectively a window inhibits the heat and ultraviolet rays from the sun is important. Energy Star windows are rated in five categories. The U-Factor and the Solar Heat Gain Coefficient show how much heat a window transfers and are the most important score to emphasis on when choosing replacement windows for a Phoenix home.

Solar Heat Gain
Solar heat gain indicates the amount of the sun's energy that is transmitted through a window. The sun's heat is transmitted through the glass in addition to the window frame and sash. The frame and sash can comprise 10-30% of the total area of a window so the frame construction is a significant determinant. Windows employ a range of techniques to reduce solar gain.

Low-E Coatings
Low-E coatings reduce the heat and ultraviolet rays that pass through a window. Low-E coatings are exceptionally thin, invisible metal layers attached to the glass. High, medium and low solar gain versions of Low-E coatings are available on the market. To further inhibit solar gain, many dual pane windows have Low-E coatings on both pieces of glass.

Gas Fillings
Double pane windows have a space between the panes of glass. This gap can be filled air or gas (Argon gas or Krypton gas). The gasses are denser than air and make it harder for hot or cold air to pass between the panes. Krypton is the heavier of the two gasses and requires a narrower space between the panes however it is more costly. The gasses are non-toxic so there is no health risk if a window is broken.

Window Frames
Vinyl windows frames have hollow spaces inside which can be filled with insulation to boost their thermal performance. Aluminum transmits heat very efficiently so aluminum windows posses poor thermal performance without a thermal break. A material which transmits heat very poorly is inserted between the aluminum pieces on the inside and outside of the window to form a thermal break.
