Anybody come out and open up the cargo area and see thin Ice on the ceilling. How to stop this, this van has electrical parts and when the ice melts it drips, like a basting top on a dutch oven.
Before we insulated the roof there would be condensation on it after a night of sleeping in it. After adding insulation the condensation was gone. Adding insulation should keep the ceiling from getting so cold condensation or ice forms.
Hi,So Gary, it sounds like the first layer of insulation against the roof metal needs to be impermeable and occlusive with my goal of being to eliminate any and all possible air gaps.
This is why foil faced polyisocyanurate is so good. Run the strips of great stuff (adhesive) across the van and horizontally on the walls so that water, if it forms, can escape to the rocker panel scuppers. They are there for that reason. I don’t think an adhesive on the whole sheet is a good idea because you are going to trap water against the van ceiling or walls. You will not stop all that condensation, but you can reduce it to almost nil and control the small amount that forms.So Gary, it sounds like the first layer of insulation against the roof metal needs to be impermeable and occlusive with my goal of being to eliminate any and all possible air gaps.
Lynyrd,Thanks everybody, lots of great info, I also just built shelves out of wood but it has been cold hear so I cant see the wood causing too much of this, if it was hot and it dried out I could see it, but not in the cold we are having at this time.. I do open up all the doors and windows on a sunny day to try and dry it out, but I will have to do the top insulation. I cant have the water droplets landing all over my electrical parts. That was the main reason for the van was to keep all of my metal parts dry and shiny. I do commercial electrical. I dig the van, but i have some bugs to work out. Like today I pulled my soda out of the cup holder on the floor, and I got my soda and the side of the cup holder came up with it.
I only get the wicked condensation on nights that are in the low 30s. And that dose not happen too often.
But as for the condensation, Its funny its like I am inside of self basting Dutch Oven.
You gotta laugh!!!
This forum is great!
