Windows typically account for 15 to 30 percent of the total heating load in a structure and may account for over half the summer cooling load. Money may be escaping out your windows.
“I encourage homeowners to think of the hot and cool spots throughout their homes,” said Darrell Smith, Executive Director of the nonprofit International Window Film Association (IWFA). “These are indicators of areas that can be addressed to help boost a home’s efficiency.”
Full window replacement may not be the most cost-effective means for improvement.
“A professional installation of window film can provide the same—if not more—benefits for homeowners as complete window replacements,” said Smith. “In addition, a film installation can often be completed without a major disruption in use of the rooms.”
According to Smith, the potential savings per dollar can be seven times that of the installation of new windows. On average, an installation on a single-family home may range from $4 to $12 per square foot, depending on the type of window film installed.
Once window film is installed, it can help block up to 84 percent of the sun’s heat—keeping a home cool in summer—and help hold heat inside during winter—resulting in lower energy bills and a warmer environment.
“An additional feature of window film is the ability to block up to 99 percent of ultraviolet rays from passing through a window,” said Smith. “This offers homeowners an extra measure of protection for furniture, floors and cherished heirlooms.”
