Duck Shrink Film Window Insulation Kit, Indoor, 10 Pack, 62 in. x 420 in.

I like the film a lot! The installation was real easy and quick. I have old wood windows in my apartment which are nowhere near to be insulated and I constantly have moisture accumulating on them every morning and dripping down. So, the film on bottom of my windows have fallen off because of moister dripping down, but I have put a duck tape on the bottom and it holds! Be careful installing the film, do not over use the blow dryer otherwise the film will shrink so much that it will come off the sticky tape! But you wont believe how much cold air that film holds, on a windy nights I can just hear a wind blowing through my windows and making the film shake, but guess what? None of that cold air is coming through! Wonderful way to save on winter electric bills! I highly recommend it!

Wow,,just exactly what I was looking for & Walmart came though. Did not want drapes & all the frills....just something simple to keep some of the air out around my windows. Found this on Walmart site by accident....while looking for window covers. Just can't say enough good things about this inventive find.....easy to install.....even for one person. Works great to keep the blowing wind at bay. I love that I can still see out of my windows and this is barely noticeable. Easy instructions.....so don't feel intimidated....it's fun and easy. What a great find and buy! Very highly recommended....just sorry I didn't find it sooner.
