Energy Saving Tip of the Week: Don’t Let Air-Conditioning Dollars Go Out the Windows!

Did you know that windows can account for a significant portion of your energy bills? Windows with low-emissivity (low-e) coating cost about 10%-15% more than standard windows but they reduce your energy loss by 30%-50%. Low-e windows have a coating which is a microscopically thin metallic oxide layer applied on one or more panes of glass. There are different kinds of low-E coatings developed for high solar gain, moderate solar gain, and low solar gain depending on the climate you live in and the direction your windows are facing. For example for hot climates and east- and west-facing windows you should choose low-e windows where the coating is applied to the outside pane of the glass as this will keep the sun’s heat out of the house. When you are buying new windows look for ENERGY STAR label. Always work with reputable and knowledgeable installers to make sure your windows are installed and sealed properly to avoid any air leaks.
