**Update** I had some questions regarding using this on double pane windows so after a lot of research. I went to www.buydecorativefilm.com and found a quote that said it was safe for dual paned glass. There were a lot of reviews on Amazon and I couldn't find one that said it was a problem for their double pane windows but if in doubt, contact a professional window tint installer. ** When we bought this house a year ago, it was the house of many firsts. One first, was the fact that this house had windows on the garage. We had never had a garage with windows before. And you know what they say about first impressions. Every time someone walked to our front door, they would pass these windows first. When I set up the garage, I put a shelf in front of the window, because almost most of the other wall space had pegboards already on them. I put it in front of the window and I proceeded to load it with just about every paint can that I had. Every time I walked by the garage, I groaned but was too lazy to move the shelf and ALL THOSE cans of paint. So, I sent my husband to buy blinds. Either he bought the wrong size or I measured wrong and it was probably the latter. But, I hated seeing the inside of the garage so much, I attempted to put them up anyway. I don't know why we didn't take them back and get the right size. I think I just wasn't happy with how the blinds looked so it didn't matter. I am not sure how I came across this mirror window film but it looked like it might be the perfect solution for me.
