Could you please advise me on a film that I can use on Double glassed windows? Is it possible to stick reflective film on outside glass of the window? I am hoping that if I apply the reflective film to outside glass it might reflect light and heat and might not heat the glass bad enough to damage it.

There are a few different varieties of window film available in our stores:
I would advise you to go with either the Crystal or Tinted varieties to maximise the external views but limit ultraviolet rays and infrared heat. The Mirror variety will almost block all external views. Window tints are installed on the inside of your windows; if you wish to install them on the outside, you might need to do some experimenting.
