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

Window Ratings
With in excess of three hundred days of sun every year, how efficiently a window restricts the heat and ultraviolet rays from the sun is important. Energy Star windows are scored in 5 categories. The U-Factor and the Solar Heat Gain Coefficient compute how much heat a window transfers and are the central rankings to emphasis on when looking for replacement windows for a Phoenix home.

Solar Heat Gain
Solar heat gain is the amount of the sun's energy stated more precisely transmitted through a window. The sun's heat is passed through the glass in addition to the window frame and sash. The frame and sash can comprise 10-30% of the area of a window so the frame construction is a critical consideration. Windows employ a variety of techniques to lessen solar gain.

Low-E Coatings
Low-E coatings minimize the heat and ultraviolet rays passing through a window. Low-E coatings are exceptionally thin, invisible metal layers attached to the glass. High, medium and low solar gain options of Low-E coatings are readily available. To further diminish solar gain, certain double pane windows have Low-E coatings on both pieces of glass.

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

Window Frames
Vinyl windows frames have hollow spaces inside which may be filled with insulation to enhance their thermal performance. Aluminum transmits heat very efficiently so aluminum windows feature poor thermal performance unless a thermal break is added. A material which transmits heat very poorly is inserted between the aluminum pieces on the interior and exterior of the window to form a thermal break.
