How to Winterize Windows With Plastic
According to the 2007 Buildings Energy Data Book, space heating is the largest single drain on the average household's energy. According to the U.S. Department of Energy (DOE), energy loss through windows are the cause of a tenth to a quarter of that heating bill. So it makes sense to winterize those windows. The DOE recommends covering the inside of drafty windows with clear plastic wrap. Does this Spark an idea?

1
Cut a piece of plastic film slightly larger than the window you want to cover. The two best types of plastic to use are shrinkable plastic film and heavy-duty plastic sheeting like a drop cloth.
-
2
Apply double-sided tape to the frame of the window. If you notice a draft coming from behind the window casing, apply the tape to the drywall just beyond the casing.

3
Put the plastic wrap onto the double-sided tape. Take your time to avoid creases and runs in the plastic, which should be applied evenly and tautly.
-
4
Shrink the plastic film using a hairdryer set on low. Constantly move the hairdryer back and forth to prevent the hairdryer from melting the plastic. Stop when there are no wrinkles on the plastic wrap.
-
5
Cut the excess plastic film from the side of the double-side tape opposite the window.
-
6
Inspect the plastic for leaks. The double-sided tape can pull away from the window frame as the hairdryer tightens the plastic. Add double-sided tape to where you find leaks.

Tips & Warnings
Check with your local utility company for possible rebates they offer for covering windows with plastic film.
Test the double-sided tape on a small area before applying to see if removing it will strip paint from the window frame.

I have several windows which I cover with clear shrink, and some have mini-blinds between the plastic and the inner window. By adding a double layer of packaging tape over the adjustment spindle at the top ( I cover about a 5" x 5" square ), and then cutting a whole about the size of as half dollar in it, I am able to run my adjustment stick to the inside. I carefully cover the opening after to minimize the cold air seepage. I get almost full benefit of the plastic skin and I can open and close my mini-blinds.
