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.Wayne

Hi,I'm using interior window covers that are a four layer:ClothMylar (shiny silver)battingCloth *added by the end user*The first three layers are called Insul-Bright

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?Wayne

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.

Crack open a roof vent to allow that high moisture laden air out.

What is generating all the moisture? Just the inhabitants or are you cooking with gas? I just got back from a trip to the Grand Canyon and it was so dry I ran a vaporizer or boiled water to raise the humidity level. I was proud to have a little condensate on the window.Dick

Not really, other than stopping the moisture before it starts. Just crack open the wallet and get the dual panes next time. You'll be a much happier camper.

I have no problem at all spending the money on dual pane windows. That would be my preferred solution. The problem is that my truck will only tow a small ultra-light TT and I have been unable to find a floor plan which will work for us in a brand that offers dual pane as an available option.

I know people will suggest a 3/4-ton truck, but I traded off one of those because my old, arthritic back couldn't stand the rough ride anymore. Besides, before I would spend money on a new TT and a new 3/4-ton truck to pull it with, I would buy a Class A with dual pane windows. A floor plan that would work for a retired couple traveling alone is easier to find in a Class A, as are dual pane windows.

Plastic wrap may be worth a try. I will see if it will stick to the window frames well enough to be a practical solution.

Has anyone tried something like this with any luck? http://www.lowes.com/pd_15328-46086-15328_0__?productId=3582748&Ntt=insulation+panels&pl=1¤tURL=%3FNtt%3Dinsulation%2Bpanels&facetInfo=

I'm tempted to try it cut to size to be a friction fit in the window frames next to the glass, and see how that works. I don't know how good a fit I can get or how durable/long lasting it would be.

I've used 1 1/2" extruded polystyrene with good success. We even put a piece of duct tape doubled on itself on one edge of the insulation board to make removal painless.

There have been posts here about air to air heat exchangers being used to get the moist air out and fresh air in, without losing much heat in the process. I believe someone in the TC subforum did it a year or two ago.

Thanks! That's really fascinating! I don't read the TC forum - maybe I should. This is good stuff.

Note: The reason for my long delay in responding is that I've been away, and had no real access to a computer.

I hope to go camping really soon. I have 3 uninsulated windows. I may try 3 of these ideas and see what works best.

Thanks everyone!

Wayne
