Hi all! I'm restoring a canned ham for the 1st time and had some question regarding insulation. It had a foil type when I tore it down. I was thinking about installing a rigid foam board type R13 insulation I between the framing an inner/outer skins. Any feedback, info, or suggestions are greatly appreciated! Thanks Isaac

Thats what I used and it works great. Easy fast and also water resistant. Plus the rating factor is a plus.

Great! Did you leave an air gap?

According to the manufacturer of the foam board I used you don't need a air gap. However my trailer did have a small air gap between skin and birch. This was because my wall cavity is 1.5 inch thick and the insulation was 1.25 inch thick.

I used 1.5" rigid foam. I rough cut it and glued it in with foam adhesive. Then I spray foamed the gaps and trimmed it flush. Here is a picture after I filled the gaps, but before I trimmed it.

I used 1.5" Tuff-R sheets, it has the highest R-value I could find (6.5/inch), and is silver coated on both sides so all I had to do was tape over the seams and frame with aluminum tape to make a complete vapor barrier. My camper has tapered rafters that are 3.5" thick in the middle, so the R-value of the center foot or so of my roof is 22.75. Been out at 14 degrees, and the old furnace kept it a toasty 75 inside...
