damp in windows

[bob galley]

I have just brought 2017 Coachman Pastiche, yesterday when sun came out for first time this year, the 2 windows facing sun had damp inside them. I have never had this before in any caravan neither has my friend. The dealer is saying its normal when temps change dramatically.

anyone got any ideas ???

I've had that with every caravan I've owned!

Unlike domestic double-glazing, caravan windows aren't hermetically sealed in a factory so expecting them to perform like domestic windows in unrealistic.

In theory you could remove the little plugs in the inner panel and blow air in with a fan but the risk is that ambient air may have more moisture than the air between the panes

Again ever since having double glazed plastic caravan windows, this can happen, and it has always self cleared as we get into the warmer seasons.

As said I suppose you could if picking a very low humidity day leave the plugs out for a few hours.
I have not needed to and would be very reticent to do so; not least because I could so easily lose a plug in the process.

Like others I have that occur in all of our caravans with “double glazed” windows. It does clear up and I’ve never removed the plugs as it may only give a very temporary respite if any at all.

As above - always had this issue. Annoying but not much you can do other than to wait for it to clear.
