Brrr! Take the Chill Out of RV Windows

When my feet hit the deck this morning in the old RV I knew something was decidedly wrong. Even with a bit of nueropathy, my sensors indicated that this was one COLD Arizona morning. The recording thermometer confirmed it: 24 degrees in Quartzsite. Yes folks, it does sometimes get a wee bit on the chilly side, even in this RV nirvana.

Part of the chill factor is that old problem of "single glazed" RV windows. Sure, some manufacturers include "storm windows" on their rigs, but by far, most of us just have that single sheet of clear stuff between us and the outside world. What's to do if you've got too much cold coming through the glass? Add your own "storm window" with shrink-fit window insulation. You can buy this stuff at nearly any hardware store or home center.

Besides the window insulation kit you'll also need scissors and a blow dryer. Some RVers say that they use an electric space heater to "shrink" the plastic into place. If you try that trick, start at a considerable distance away from the plastic lest you find the source too hot and burn a hole in your plastic, rather than shrinking it into place.

Here's a little video that shows you the basic principles of installing the stuff. However, instead of sticking the sticky tape away from the window, most of us can stick it directly to the window unit itself. You may need to "work around" problems like window cranks. We might add too, that the video makes it appear that there's a lot of left over wrinkles in the finished product. We're not sure if that's an illusion, or if our "installer" just didn't work long enough on getting the wrinkles out. With effort, your final product will be flat, tight, and highly viewable.

  • We have used this product in our sticks and bricks homes over the years and would highly recommend it. It is very easy to install, and it does shrink to a very clear, easy to see through, finish. I have watched the plastic move a good two inches due to wind blowing through cracks in window installations during the winter in the houses, so it really works!

  • We used this product in our class A 36 foot motor home while we stayed in Colorado Springs for Nov and Dec. It worked terrific!! We installed it and it was perfectly clear to see through and no wrinkles. It really insulated our single pane windows. We highly recommend it!
