Insulation?'s

Wondering what everyone used for insulation on ceiling and walls?
I was thinking of using this stuff.

Re: Insulation?'s

I recently used the 1" version of that on my 1" square tubing camper shell frame for my Jeep Comanche PU when I rebuilt it. Very easy to use and notice how I curved it by simply scoring in multiple relief joints about 3/4" deep. I found it easier to cut the perimeter shape with a jig saw (messy) rather than slicing it. It is far superior than the fiberglass batting that Callan Camper used in the original build. I like the solid backing it gives too.

Re: Insulation?'s

Foam panels have something like 2x more insulation value inch for inch than fiberglass, plus it doesn't itch when you work with it. Might be worth considering a foam with a radiant barrier skin for the extra that gives. You can also buy foam with a scrim backing that is pre-scored for contouring. That stuff is very easy to use and you can stick it down with spray adhesive.

Re: Insulation?'s

i used expanding foam in a can...great stuff its called....there are different strengths or rate of expansion...

i highly recommend minimally expanding foam version and i cannot stress enough that you have to be careful with it....

i used it on the wall "studs" and nooks and crannies in my chevy express 2500 and it expanded so much (despite my extensive knowledge of the stuff and what it does) that it pushed the sheet metal away from the stud and i could see the outline of the studs on the outside sheet metal of the van...

i almost #(*$&* myself...it eventually subsided...mostly...i can still just barely see an outline...

so..aside from that...the stuff works incredibly well if you mind the above plus, dont let it get into drain holes or create wells where moisture collects...you also have to be ok with it being permanent...

end result for me is not one bit of condensation inside van no matter what the weather is doing or if the temperature swings rapidly....

i should mention that i boondock 100% in my van...i also have a fantastic fan that runs 24/7 pretty much

oh and you will use more cans of that stuff than you think
