Hello, I've been researching a lot about applying reflective film on the inside of a double-pane window. Is there any risk? The brand I use is Reflectiv SOL 101, with a total solar absorption of 33%. I would also like to ask: Has any of you used APA Reflective Window Film (SI/WI-911) before? If so, what do you think of it? The technical data sheet says that for double-pane window it should be applied outside. Can I apply it inside anyway? Thanks!
