Bubble Wrap Window Insulation
I've used bubble wrap on windows for
This is a simple technique for insulating windows with bubble wrap packing material. Bubble wrap is often used to insulate greenhouse windows in the winter, but it also seems to work fine for windows in the house. You can use it with or without regular or insulating window shades. It also works for windows of irregular shape, which can be difficult to find insulating shades for.
Its been 3 or 4 years since I put this page up, and I've heard from MANY people who are quite happy with using bubble wrap for window insulation.
The view through the bubble wrapped window is fuzzy, so don't use it on windows where you need a clear view. But, it does let plenty of light through.
I like the medium to large size bubbles. The larger ones appear (from surface temperature measurements) to insulate a little better, and you still get a nice artistic effect looking out of them. The small bubble warp totally obscures the view, but you still get light. Most people seem to prefer the large bubble version.
If you have trouble with the bubble wrap separating from the window when the film dries, you can try adding a little Glycerin to the water, but this probably won't be necessary.
A few small pieces of double back tape can be helpful on really stubborn windows.
The bubblewrap can be installed in the fall, and removed in the spring. Judging by how mine looks after a year, it may last quite a while.
When you take the bubble wrap down, put a small number in on the upper right corner of each piece of bubble wrap, and write down which window that number goes with on a piece of paper. Save the paper for the installation next fall. This tells you instantly where each sheet goes, and which way its oriented.
