Review: Works very well. - I’ve used this kit for the last few years to seal my windows in my Motorhome for the winter. The adhesive is very sticky. The product works very well in keeping the heat in and the elements out. Ordering more for next winter.
Review: Amazing and cheap - Amazing what you get for the amount you pay. It's not perfect but it definitely helps a lot to prevent the cold air from coming in. It's also pretty easy to install and the adhesive works well. You might need and extra person to help since it's so big, and if you want to get it perfectly straight the second person can really help.

## Questions & Answers

**Q: Does the film come as one large piece you have to cut or is it perforated for the 5 windows? I would like to use it for one large window (7ft x 4ft)**
A: It came as 2 folded sheets. I seem to remember 2 7'x5' sheets. The best way is to cut the amount you need a little bigger than the window and use a utility knife to cut the excess off after it's applied. I was able to get 3 huge windows completed and that was after messing 2 windows up by accidentally stabbing the film when my knife slipped when cutting the extra off. So be careful.

**Q: would this work on a window with a window AC unit?**
A: After I bought this I realized that the thickness is only .07 which is crap!! paper is 3.0 thick so that gives you an idea of how thin this stuff is spend extra on 3m products or something that is thicker I think the thickest they sell is 1.5 but its worth a few extra bucks anything should be able to go over a AC unit as long as its long and wide enough.

**Q: Will this work for humidity? We live in an apartment with patio doors that have terrible insulation and humidity gets in.**
A: This product adds a second layer to a single pane installation.  It is a little difficult to imagine that a single pane is letting moisture through unless the caulk (glaze) around the pane has deteriorated and there is an air gap.  If that is the case, the window should be re-glazed.  If what you are seeing is condensation on the inside of the window, that is because of a warmer moist inside air and a cold temperature outside.  That doesn't mean the humidity is coming from window itself.  Adding a layer of this film will add an insulation layer and help reduce the condensation.

**Q: Can i use this for my sliding glass door and if I do can I still open the sliding glass door?**
A: Thank you for your question! After installing the film, you would have to pull it off to open the door.
