Hello everyone...I have read through all the posts on rigid insulation that came up when I used the search function, but the newest was 2013 (am I doing something wrong BTW?) so I thought I would ask again...those of you who are using rigid foam do you leave an air gap and if so, is it better to leave it between (a) skin and foil backing or (b) between panelling and rigid foam? and what is the current thought on using the sheathing tape or just cut to fit tight? and do you run wires by scoring grooves in the foam panels where necessary or run them through the air gap? My 1967 Glendale has 1 5/8" framing, any suggestions about foam board thickness would be appreciated!

I tight fit my foam, 1 1/2" in 1 5/8 framing. There is a tiny gap between the frame and skin. If it's fiberglass insulation, I also cover the top with a plastic sheet before the skin goes on. Aristocrat did that and I've found more good Aristocrat ceilings than other trailers.
Normally, vapor barrier goes on the heated side of the wall. It depends where you live how it's placed.

Vapor barrier according to how you camp. If it's in hot weather, on the outside, cold weather on the inside.
You can also vapor barrier on the inside and wrap with house wrap just before the metal goes on. Sort of a double protection.
Anybody else want to chime in??

Anybody else want to chime in?? Please do...! I'm close to this point for inward barrier. Live in S. Indiana and we usually try to travel more in the edge of "off-season" to avoid crowds and to get what critters we are going after. (photography) |
