Hi all,

Just got back from a winter weekend in my 88 Elddis Cyclone. As it was so cold we had a fan heater on nearly all day and a small oil radiator over night. In the evenings I noticed that condensation was forming on the ceiling boards. It was running in straight lines accross the caravan almost were I would imagine roof batterns to be. It was also at the side in side of cuboards etc.

I accept that condenstation forms in a cold cuboard when the rest of the van is warm, but what about on the ceiling boards in the warm?

I have resealed all the awning rails and most of the horizontal rails.

The underside of the cushions was also damp in the morning and the walls behind the upright cushions.

Would this all be normal this time of year or do you think there are possible damp issues?

One more question, I have a rather old Telt Larzen awning with canvas sides and a plastic roof. Loads of condensation had gathered on the underside of the plastic and made the inside of the awning very wet. The plastic looks sound so dont think its leaking - even though it did have 2" of snow on it. Is there a trick of preventing this build up?

Sorry for the questions

Mark

Sounds Pretty normal. This time of year you don't just need heat, you need ventilation as well. The condensation will form along the roof battens because they are not insulated, i.e they are connected directly to ceiling boards and to external skin of the caravan.

I got a bit worried so i put the two hobs on for an hour and shut the door.In about an hour everything seemed dry again until i looked in the cupboards which were really condensing.Ive left all the cupboards open now to dry out.

You can do that on a warm, dry day with great effect - but I can't remember the last warm, dry day! The use of moisture traps (crystals, salt) helps keep the air dryer, and reduce condensation, too.

Thanks for that rob.1.Tbh i think i may have closed the vents at the end of last season one cold evening.Must go back and do as advised by you and viggo.
