I've installed window film in my room to combat the intense heat from the sun, especially since my windows get direct sun exposure all day. I've only put it on one window and the heat difference is shocking—while the filmed window feels almost burning hot to the touch, the uncovered window is only slightly warm. Interestingly, despite the heat buildup, I notice that sitting at my desk facing the filmed window feels cooler than before. I missed the mark and bought only one film, so I haven't had a chance to compare them side by side. I'm concerned about the heat buildup—could it damage my window? I've read conflicting advice about installing the film on the exterior versus the interior, mainly due to weather factors. Plus, I have an awning that helps, but it's only spring and my window is already getting super hot. Any thoughts or suggestions?

Yes, you should definitely be concerned about the heat buildup on your window. According to Eastman, the parent company of Gila Window Films, applying film to dual pane windows from the inside can risk overheating the inner pane, potentially damaging seals or even breaking the glass. It’s crucial to choose the right type of film for your specific windows. For peace of mind, consider reaching out to their technical support for advice on the best film options. Just keep in mind that some films can cause issues with heat absorption, which might lead to premature seal failure.
If you own your home, consider installing solar screens instead. Unlike traditional window film, these screens are thickened with plastic to block a significant amount of sunlight—up to 90%! I put solar screens on several windows in my house, and it really dropped the temperature in my hottest room by around 10 degrees. It’s a fantastic way to enhance your cooling without the risk of heat damage to your glazing.
Definitely check out solar screens! They can make a huge difference.
That's a great idea! I should definitely look into solar screens. Thanks!
