first and was ridiculed for that on this list several months ago.
My crawl space is tight (for humans), but well-ventilated, so I'm
going to go with this option as I think it is the most practical.<br>

Leslie,

You may want to re-consider the idea of foaming the floor in a
crawl space. My concerns would be that the foam would act too well
as a vapour barrier, and you may have moisture/mildew problems
down the road in the crawl space. I AM in Canada, so your
geographic climate might create different problems than here.

I always design any neccessary crawl spaces as a definite part of
the conditioned space of the home. That means insulating the walls
and the floor of the crawl space, and leaving the floor as a
vapour-open plane, as well as including the crawl space in the
heating design. This avoids condensation trouble, by keeping the
air warm and dry.

<blockquote type="cite">I am in NE Oklahoma. I'm in the process
of getting estimates for crawlspace insulation in the floor
joists--closed cell foam. My crawl space is dry now that we've
fixed some plumbing problems, but I'm having some cupping issues
with some wood flooring and part of the fiberglass batts that
were originally in the house when we bought it were taken out
over time for this and that. Anyway--closed cell foam seems to
be the best solution.

The first guy who came this morning wants to quote me 1.5" foam,
though said he would quote 2" if that's what I really want,
saying that would be enough for "Canada". I understand about
the benefits of air sealing, but I was still thinking I would
need more inches of foam according to what I've read on R-value
& this area. Thoughts?
