Bora-Foam Insulation from Crawlspace Depot

[@christianjohnson6519]

So this is only needed if there's no insulation under floor joists?

Is doing some CS better than none at all? In The manufac. Home we bought on a lake, they left the trailer chassis in the CS. NO way I will be able to do liner under that.

Joseph, great question! If you can't put down a vapor barrier, you can't protect the crawlspace from rising damp. This means you won't we able to control the moisture.

Where can you buy the foam board from and what is the r value of it and does it need a vapor barrier behind it?
