We all know that sitting under a tree can help keep you cool but did you know that using the same low-tech idea can help cool your home or business and save you money. According to the Consumer Energy Center a properly installed awning can reduce heat gain in your home up to 65% on southern windows and as much as 77% on eastern and western windows. That's pretty significant!
Shading your home with window awnings can reduce the temperature indoors by as much as 20 degrees on a hot day!
About 40 percent of the unwanted heat that builds up in your house comes in through windows. Although both exterior and interior shades can control this heat gain, exterior awnings, are far more effective, since they block sunlight before it enters the windows.
Awnings rate high as shading devices because they block direct sunlight. Usually made of fabric, they are attached above the window and extend outward and down. A light-colored awning does double duty by also reflecting sunlight. Living in New England, with cold winters, you will want to retractable awnings to take advantage of the desirable winter heat gain.
