Ways to Insulate RV Windows (That Don’t Block the Light!)

One of the biggest causes of heat loss for RV owners who camp or live in an RV year round in cold winter climates is single-pane windows. Additionally, if the RV is humid inside, condensation can form on the cold window surface, leading to mold or mildew problems.

Methods for Insulating RV Windows

Hang Heavy Curtains Covering your windows with thick, insulated curtains can make a big difference in helping to retain heat.  You can open them during the day to allow the warm sunshine to come through the glass.

A lot of people cover their RV windows with Reflectix. Additionally, while Reflectix may help insulate, it also repels an effective free source of heat: sunlight!  Some RVers put Reflectix in their windows at night and take it out during the day

Covering the Windows with Reflectix

Clear, Heat-Activated Window Film

If you’ve never used it before, basically you put double-sided tape  all the way around the window frame, then cover the window with plastic stuck to the tape, and then you blow a hair dryer on it and the plastic shrinks and all of the wrinkles smooth out and the seal around the edges traps a layer of air between the plastic and the glass.

I wanted to share this insulated windshield cover designed for Class C motorhomes because I think it would be a lot easier to use

Insulating RV Windows with Bubble Wrap To cover a window with bubble wrap, all you have to do is dampen the glass and stick the bubble wrap to the glass with the bubble side facing the glass.

Velcro Window Covers Made from Clear Vinyl

I did use one more window covering method last year, just for a few of my screen windows, and that was to make clear vinyl covers attached with Velcro.  I did this so that I could remove the covers and open the windows on nice days.

Combining Window Insulation Techniques

1. Shrink film on the hall window  2. Bubble wrap on the window behind my husband’s desk  3. Plexiglass on my big windows. 4. Vinyl covers attached with Velcro on my screens and smaller windows.

Making DIY Plexiglass Storm Windows First I used a Sharpie to mark where I needed to cut.  Then I scored the mark several times with the utility knife over an old cutting board.

And finally, I grasped the corner with a pair of needle-nosed pliers and easily broke it off.

I sanded the edge so it wouldn’t be so sharp.

To adhere the plexiglass to the window frame, I used my favorite invention ever, clear acrylic mounting tape.
