Insulating windows

I have big problems with condensation on windows camping here in the mountains in spring and fall. I’m trying to find a solution.

Is there some way to easily and effectively insulate windows at night, yet remove the insulation layer during the daylight hours for light and, as needed, some ventilation?

I’m thinking of something that could seal well enough around the edges to minimize condensation and prevent a little heat loss, yet be removed and rolled-up or folded during the days.

I’ve put the clear heat-shrink plastic over the windows I don’t need to open, and it works great. But the others can get condensation like crazy. I’m mainly wondering if there is a solution other than dual pane windows for my next RV, although I'd also like to find a good solution for our current TT in the meantime.

  • Hi Wayne,

    I surrounded each window frame with velcro. That way the frames can't conduct heat to the outside world.

    I had no condensation issues--but I live in an extreme cold region. Your circumstances may be different.

    I used it over windows, skylights, vents, the entry door, and also made a "blanket" to separate the cab. A total of 27 yards of material.
  • Thanks, Don.

    Insul-Bright looks interesting. Looking at the link and some results from Google, I think it has potential for my situation.

    How do you hold the end product against the window? How well does it reduce condensation on the window glass in cold weather?

  • Hi,

    I'm using interior window covers that are a four layer:

    Cloth
    Mylar (shiny silver)
    batting
    Cloth *added by the end user*

    The first three layers are called Insul-Bright
