Bests & Worsts Reviews from Amazon

My second floor master bedroom has an addition with nine floor to ceiling windows. I use this room as a home office but in the summer it feels like a mini greenhouse with all the windows and the sun blazing in. This film really helped to control the heat & it was pretty easy to install. My windows were not exactly the same width as the film. I've got some tips I figured out along the way: I gathered up some tools - a metal ruler, a razor knife, and a silicone shower squeegee thing. Once the film is cut roughly the right size (I left about a quarter inch extra), Use soapy water in a spray bottle and spray both the glass and the film. I used dish soap. Once its evenly misted lay on the film starting at a top corner. Line up the top edge and one of the side edges and then spray a bit of soapy water on the back. The soapy water helps the squeegee slide easier and I ended up pretty much zero bubbles after I figured this out. Once it smoothed out you can use the ruler and the razor knife to trim the other side edge and the bottom edge straight.
