If you’ve lived in the Phoenix area for very long, you know energy efficiency is a must to prevent you from going bankrupt from air conditioning costs during the long summer months.

And, because we do live in the desert, temps manage to dip low enough during those winter nights to necessitate turning the heater on.

Whether you want to keep the heat in or out, energy efficient windows are your best bet for saving money on energy costs.

So, how exactly do energy efficient windows work? At the core of what makes these windows an ideal investment is advanced engineering and technology that has been developed over the past few years.

Preparing the Window

Energy-efficient windows still use glass, but use a low-emissivity (Low-E) glass, which not only provides a barrier for sun rays, but shields the inside of your house, helping you maintain a consistent temperature.

For example, in the winter, Low-E glass keeps the heat inside and the cold out. In addition to the coating on the glass, many different window manufacturers produce windows with different glazes, tints, or reflective coatings. Each finishing step fulfills a different need and helps you find a unique way to save money and energy.

Window Construction

In multiple-paned windows, manufacturers have found great benefit to using gas fills. The gas helps to reduce the rate of heat transfer between the outside air and inside of your house. In the frame, adding polymer structural foam has become an integral part of an energy-efficient window. Previously, manufacturers often used metal to insulate the windows.

And when you’re ready to purchase, ask about the U-factor or U-value. The U-value shows the window’s resistance to heat and the insulating properties. You want a number that is low—energy-efficient double-paned windows usually have .3. and triple-paned windows might get as low as .15. In a triple-paned window, you’ll get a higher UV blockage rate as well.
