i drive a combo van and when i get in its full on condensation on the inside of the panels ie roof skin,
surely this cant be right,now i know i have 4 minor holes in the roof i need to plug where the roof bars where,
im wanting to ply line the van after christmas is there anything i can do before i do this to protect it a little
anyone else have this problem

 

If it's got condensation, it's got water coming in somewhere. Even a small amount can cause condensation. Even if there's a little bit sloshing about in the wheel well, or on some damp clothes in the back...

 

Hardware shops sell dehumidifying crystals. For sheds and garages, they'd work overnight. Cheap solution would be a tray of uncooked and a tray of table salt

 

I have the same problem with the metal roof on my garage, it freeze's over on the inside then when it melts it drips over my car. Im off to get some insulation boards after work, go a try and stick them up with expading foam.

 

That wont really help much IMHO - not unless you give the room/garage a heat source the boards are going to get almost as cold as the metal roof, or find the source of damp in there and cure it..

I've got no DPM in my concrete garage floor (its very old) and the rain water soaks into the slab at the front, and it gets damp and horrible inside... Another job on the list!

i used to work in spray foam insulation and we used to do garage roofs and storage containers for market traders to stop condensation dripping 15mm thick on the roofs,

i think i will plug the holes in the roof up,reseal the aerial and get some dehumidifying crystals and give that a go, problem is the roofs in these vans aren lined at all so is it always going to condensate?

 

Thats what I did 7/8 years ago and it stopped it happening... Mine used to have frost on the inside of roof lol
