## Questions & Answers

**Q: What is the measurements and thickness of this?**
A: As it says on the package, the film is 62 inches x 25 feet.  (I don't see thickness specified anywhere, and I don't have a gauge to measure the thickness of my leftovers.)  How, you might ask, does that comport with the specified package length of 35.5 inches?  Well, the film is doubled over before being rolled around the cardboard tube, so when you cut, say, a 44-inch length of the film as it comes off the roll, you get a 31-inch x 44-inch piece of film unless and until you unfold it.  Aye, but there's the rub.  The film sticks to itself so strongly that it seems darned near impossible to unfold it -- though I usually manage the trick after an hour or two of repeated attempts or by hanging it from the top of the window frame and letting gravity and weakening of static electricity unfold it for me.  At any rate, it seems like a pretty thick film while doubled up and a pretty thin film when unfolded, but I couldn't give you a number of mils of thickness.
      One other observation about this film: the provided tape really isn't up to the job of holding film to window frame (especially if you tighten the film with your dryer to take out wrinkles), even if you use a double row of tape.  I find carpet tape to be much better at holding, though it's hard to get the carpet tape off at the end of the season without pulling up some speckles of paint with it.
