security films do offer better physical protection but they aren't energy efficient at all
I suggest you get tinted films but thicker ones - Solar Safe Films sell 6mil. If you're worried about someone trying to steal something from your car, good tinted windows should hold up quite well against the smacks of a baseball bat. You get both the physical protection as well as save up on fuel costs.
If you want to fit your own films, be prepared to spend a lot of time and at least a couple of hundred quid. Many in the past have complained the same things
It's easier to just go to a car dealer and get it done. They have the experience and that's what you're paying for. It would be around the same price as doing it yourself anyway.
