Hi, working on a stepvan conversion.... hopefully that doesnt disqualify me from this forum as so much of what we have to do to our vehicles is the same.
Ive gathered a lot of knowledge from this forum so far as it all crosses over.
I had a question about cold weather insulation that I was hoping someone had experience with. Im currently living in a warm climate so very little experience with cold... but will be transitioning with vehicle to very cold environment soon. I'm trying to upgrade insulation starting with ceiling which is all sheet aluminum supported by 1.5 inch thick ribs at 3 foot intervals. Im planning on installing a wood stove as my primary heat source for simplicity as tapping into fuel tank with a webasto or using propane is something I dont want to deal with.
Presently my plan is to use 1.5 inches thick foil faced polyiso glued to roof and taped at seams and then facing that again with thick aluminum foil so I dont have to stare at ugly lettering embossed on insulation sheets. I was wondering mainly if the foil idea would add a significant amount of warmth by functioning as a radiant barrier reflecting heat downwards off the ceiling? Is a reflective radiant barrier like this effective in the cold (albeit maybe a bit ugly) or should I just go with a more traditional ceiling finish because this radiant barrier wouldnt do diddly squat?
Anyone have experience with this?
As for walls, those are presently uninsulated as well. Im mainly concerned about condensation building behind them so was considering 1.5 inch thick expanded cork insulation which has some permeability / breathability.
So cork walls and aluminum ceiling....unique look for sure...function over form though is my mantra
