Cabin lining for warmth

[dunedin]

Did you manage to sort that issue? It plagued me through the colder months, I used some anti condensation underlay but it's made very little difference.

Decades ago the caravan industry sorted the damp under the mattress issue by moving from solid (ie plywood) base under the bunk to slats instead. Works well.
Our caravan also had thin panels at the sides held 1cm from the outer walls, which kept the edges of the duvet dry from condensation.

In my experience putting matting or similar underneath the mattress on top of the bed base is not over efficient. A much better answer is to stick insulation underneath the bed base, the insulation is then on the cold side of the system with a solid layer above it. I have used

Celotex GA4000 General Purpose Insulation Board 2.4m x 1.2m x 100mm

underneath all of my beds with significant results. If you can, go even thicker than 25mm.

Found a photo of what I have done to the underside of the bed bases. This is the underside of one of the hatches. I have stripped the aluminium of the glued side and just used something like Sticks like sh1t. You do not have to fit it 100% perfectly in one piece, just cover as much of the bed base as possible. As the foam is light, it will just stick without extra fixing. Remember the space under the bed will be around the same temperature as the water, 10dec C hence why you can get so much condensation under the mattress unless you do this job.

Looks like another Job to add to the list.

The best result I had was to get some sprung IKEA bed slats cut down to fit the V berth and a few holes in the underneath locker lids, it kept the mattress dry at least. I never got around to insulating the lockers.

We have just, last week, bought some more having had success with the first ones. The originals were bent (so sprung?), a sort of gentle curve. They, or they do in Oz, come in various 'single' bed sizes from IKEA and we bought two sets and we cut to fit. The berth(s) need fiddles to retain the slats. Cheap. As mentioned - we cut holes to the void underneath.

We had already invested in a decent duvet.

I did think of wiring computer fans as extractor in the void, underneath - but never got round to it. Condensation is not a big issue....here..... most of the time.

My previous boat had one berth (the stb aft quarter) where it was on one side bare grp hull, I stuck cork flooring tiles on this this area which provided an excellent insulation. Certainly no condensation problems were experienced after thi.

This subject gets a regular showing - What headlining to use ? Foam Backed Vinyl failed etc.

I have been pleasantly surprised by the Van Lining I replaced my fore cabins Foam Backed Vinyl with ... the fore-cabin feels better ... less humid, and maybe a bit warmer. I suppose its human nature coming in as we want what we do to improve things.
I did consider thin wall insulation '3mm Depron' as water does not affect it ... can be eased to shapes / curves ..... before applying the Van Lining - but in the end decided not. I'm glad I did as the lining appears to be fine on its own.
Application was far simpler than I imagined. I had watched YT and read all sorts about getting surface clear of old glue and the problems of dust etc. I had vacuum cleaner running while pulling down old Vinyl ... I knocked of hgh spot / lumps of glue and just generally gave a good stiff brush job to remove any loose crap. Applied spray adhesive to lining ... having used the old vinyl as template ... lifted and smoothed into place. I actually had to pull it away and adjust position a couple of times ... no problem ... once positioned - gave a good smooth pressing all over ....

I would love to be able to line and fit panels as some do ... but I am well aware that my attempts would never look as good as many we see on forums ...

Our forepeak has terrible condensation (2 adults, small volume). I have looked at depron too but unsure of adhesive(s) to bind the depron to the boat and the lining (unfoamed vinyl probably) to the depron. Did you get as far ws identifying suitable adhesive? IMO boat installation asks a lot of tbe adhesive - overhead, high substrate temperature in summer plus generally humidity. Thanks.

You have to be careful to ensure that the adhesive is Foam Safe. Usual Contact adhesive will dissolve Depron ... you can watch it eat it ...

A common adhesive to use is Foam Carpet spray adhesive. But as you say - what will keep it up in such conditions. Depron - we use it for building models - then the adhesive to use : UHU Por .... Epoxy ..... Hot Glue ..... so out of those maybe the Epoxy is the best ?
