I’ve found that the tinting doesn’t do much good. We have burglar bars on the inside of the window so as an experiment, I put my laser thermometer on the bars of a window that had tint vs one that had foil (both on the same wall) and it was a 15F difference. We’re in TX, so it’s been over 100 every day for the past two months or more.
Well, the desired temp inside is 70F, the bars behind the foiled window was 80F, and the ones behind the filmed window were 95F. So I would say yes.
