I had considered blown insulation, however, I suspect the floor above the
overhang doesn't have much of a vapor barrier above it and I need something
that would not only insulate but serve as a vapor barrier.
You might be thinking, "well just use a piece of styrospan along the floor,"
but I have doubts that I could get a 2 foot piece to fit between the joists
and seal it properly.

I'm still thinking expanding foam and doing the job in stages to minimize
any adverse expansion effects.

Any suggestions for diy products/vendors?

Hi,

I have a 2 foot overhang on my house that I'm looking to insulate. The
overhang is about 12 feet wide and is on 2 x 12 joists spaced at 16 inch
centers. It has been stucco'd over the bottom, so I can't easily insulate
from the outside. There is an opening on each joist cavity in the
basement
with about a 6 to 8 inch gap and I was looking at using some sort of
expanding spray foam.

My question is, are there any diy kits out there that will allow me to
get a
nozzle into the cavity and fill with foam? Doing this much space won't be
cheap, so I would need a bulk kit of some sort.

I've googled a bit and only come up with companies that do the job for
you.
I'm more than capable of doing the job myself.
