Why Window Film Voids Window Warranties

When Action Window Tinting came to my house to offer an estimate for installing window film on my house (see last blog) I told him I wrote for Door and Window Manufacturer (DWM) magazine and he said, “Oh, you write for the companies that want to wash their hands of film.”

So then we started talking about window warranties. We spoke about the survey DWM magazine performed in which respondents were asked:

Do any of the following situations void the window warranty offered by your organization?

Change in home ownership—47 percent
Use of window film—71 percent
Failure to water test—6 percent
Other—35 percent

In 71 percent of cases, manufacturers said the use of window film voids the warranty.

It’s easy to see both sides of this issue. The window film folks think: they do a good job so why shouldn’t the window continue to be covered? But from the perspective of the window manufacturer I can see why they wouldn’t want to cover the use of film. If a manufacturer could be 100 percent sure of the quality of work provided they might be more apt to continue the window warranty. But even Andrew admits, “all you need is a tax ID number to start a business.” He concedes that many companies don’t do a good job at film installations.

There are any more issues at play when it comes to installing window film and the effect this may have on IG units.

  2. Make sure you ask whether your window film provider can give you a glass breakage warranty.

    If solar window film is going to cause glass breakage then it is going to occur relatively quickly after installation. The most common time is Spring on East-facing windows.

    GP Window Films in the United Kingdom provide a 2 year manufacturer backed warranty on many of their window film installations. A careful analysis is made to ensure that their window film is compatible with the type of glass.

    More information about glass breakage is available on the glass facts page.
