Hi, I use window tint from tinfit. You can find more her
https://www.tintfit.com/shop/car-window-film. I use it for both cars and at home. Still, I don't like excessive heat and a constantly hot sofa, so the film has been an escape from all that. I can sit on the sofa and drive without getting heat on my legs and back. I think you know this disgusting feeling. Everyone has sat on those hot seats at some point.
