camp crooked Member	# Posted: 28 Feb 2014 03:43pm Reply I have a 12 x 20 camp on concrete peirs in VT. summer and winter use. I am gradually fixing all of my mistakes from 14 years ago. I have 2" foam insulation on the bottom of the floor joists. I am thinking it would better insulate up against the plywood floor. Should I vapor barrier? What is being used out there in my situation? Thanks

We didn.t add vapor barrier, Not sure about if you should or not. You could add spray foam in any gaps. We then covered the bottom of the joist with used roofing steel. We have porcupines that would eat our plywood floor, also keeps out rodents , and critters. Has worked out good. Old243
