Hi, I live in the UK where sun exposure doesn't seem to be much of a problem. But in the summer the heat and glare through my conservatory windows was unbearable. A friend recommended solar window film from https://www.tintfit.com/shop/ to me and it was a lifesaver. It has greatly reduced the heat and I can now happily sit out there. It is much cheaper than replacing the windows or installing an air conditioner.
