Demountable camper group

I've been searching for the link to a product which can be used under a mattress to reduce condensation. I can't put slats in as the headroom is already limited enough. I've seen it on the forum but can't seem to find it again. Can anybody help. Pretty please.

in here?

I couldn't find it either Keith but I think this is the stuff ...

I think it's more commonly found in chandlers than in motorhome/caravan places but, as always with chandlers, they don't give it away! £45 for 2 square metres

Thanks Martin. That's the stuff I was looking for. I've put a link on my desktop so I don't forget it again.

I wonder if there is a low-cost industrial material that could be bought more cheaply and do the same job?

Steve.

I've been searching but com up empty, so far. If I spot something, I'll post it here.

sure there would something else structured like that cheaper, I was thinking more a packaging product I'll look as well

Not a lot cheaper but I wonder if these would work ...

The foam is open cell so air ought to be able to move through it and I reckon if the tiles were laid in alternate directions, as in the pic, the ridges might help as well.

45mm is a bit thick and if I'm not mistaken the foam is pretty soft and might not maintain any channels when under some duress (fat bastards). Still looking.

that looks like a membrane used in construction its marketed as 'insulation' as a by product bet you!
