Does window films cause seal failure when applied to Insulated Glass (IG) Units?

No, window films do not cause seal failure. All of our Huper Optik and Panorama films are IG unit safe. When recommended films are applied to the inside pane of an (IG) unit, there will be some absorption (except with clear safety films) of the sun's energy, which will increase the temperature of the glass pane. Some of this heat will transmit to the airspace, slightly raising the airspace temperature. Even a 20° F increase (unusual for most films) will result in a less than 3% change in air pressure, whereas properly made units are designed and tested to withstand 22% changes in air pressure.

Risk of seal failure is greatly determined by the quality of workmanship and the quality of materials that go into building the (IG) units. The best guard against seal failure is to purchase well-made units from reputable window manufacturers that have solid experience and histories with insulated units. Most films come with a standard 3 year (IG) unit seal failure warranty. As a premium warranty dealer our Huper Optik and Panorama/Saint-Gobain customers automatically receive additional coverage at no cost.
