I have heard that if you install these filters on the inside facing pane of glass, the glass can crack as the heat builds up between the inside facing and outside facing panes of glass.
Have you found one that does not do this or do you have any comments about this risk?
- mrtksn 3y agoHaven't had any problems so far. The film gets very hot, it's inside facing so I've touched it out of curiosity. I don't expect to have issues with it, unless the glass with the film does't have enough space to expand but my windows are European style UPVC so they are quite robust and well made. AFAIK there's an argon gas in the middle, must be well engineered and accounted for expansion.
- voisin 3y agoThis would make me nervous. Sure, things are holding up now, but what happens when that heat exceeds design tolerances on the seals? Does the warranty stand up if you have this film installed?
