We have some windows that, in retrospect, we should have had made with frosted glass for privacy.

We'd like to try some DIY window film to see if it's any good, but the only one from Bunnings or Mitre 10 that's wide enough is this one. However the instructions say "not to be used on double glazed windows", but don't say why not.

Does anyone have any idea why this warning would be there? All of our windows are double-glazed, and I don't understand why it would make any difference.

I could be wrong, but I understand (from a window tinting chap) that the reason is heat. When you have the film on the inside pane, the internal gas heats higher than it should in the sun, and expansion can be greater than the window is designed to withstand, and the window can pop. Something along those lines.

People often mistake me for an adult because of my age.

Keep calm, and carry on posting.

About five years ago I did several double-glazed windows in our place with frosted film from Bunnings. Can't remember the brand. It was a little tricky to do but with perseverance it worked out really well - I had to work at it to get some air bubbles out from behind the film. Pleased with the result.

Sometimes I just sit and think. Other times I just sit.

We have some film on a double glazed window within a door. Been on since 2013, and no issue. It does not get direct sunlight.

You can buy spray on frosted glass. I watched a couple YouTube videos on it (recommend watching them to see how to best apply it). Bunnings sells it. No idea personally how well it works.
