Department of Energy article entitled "Energy Efficient Window Attachments" where they discuss window film energy saving benefits. - Energy Saving Window Film in Iowa City, Iowa

In an article by the Department of Energy website Energy.Gov entitled Energy Efficient Window Attachments, they discuss the window film energy saving benefits as well as the benefits of several other window covering technologies. They highlight window films in the list and have very positive things to say about the energy saving benefits these films provide.

As the article states:

“Window films help block against solar heat gain and protect against glare and ultraviolet exposure…They can be useful for homeowners who don’t want to block views with other window treatments, but who have issues with glare and solar heat gain. They can also be a good choice on windows that are difficult to fit with other window treatments, or in places where artwork, furniture, or carpeting could be faded by UV exposure.”

Window Film Energy Saving Benefits Discussed by Department of EnergyThe article goes on to discuss how different window films are the first window attachment to be rated by the National Fenestration Rating Council (NFRC). This rating allows you to compare the performance figures of differing films on an apples to apples basis. Regarding these labels, the article states that film “includes the solar heat gain coefficient (SHGC) and visible transmittance (VT) of the window film, both numbers between 0 and 1. The lower the SHGC, the better the film is at blocking heat gain. The higher the VT, the more potential for daylighting.

It’s nice to see window films recognized by a third party rating source for their energy saving abilities. Moreover, it is even more satisfying to see the recognition coming from The Department of Energy as they discuss their role in energy efficient design.
