Default Floor/crawlspace insulation

Hi, guys. My eyes kinda glazed over a little while back, so perhaps an
interested party can translate for me: Is this merely a case of someone
wanting a cold floor to be less cold when they put in a new, laminate
flooring if I recall right, or is the problem/desired result a bit
deeper than that?

Heh. I have a skinny nephew, but he's an ADHD kid, not too dependable on
the project front.

You will want to find out not only about the insulation that is not there,
but also the condition of the wood that is there. If it is damp due to poor
ventilation, you may have a bigger problem than you think.


I suppose. We've never had a major moisture problem in the basement. In
this 19th century house there are of course all sorts of wood elements
that might give one pause and short of a major obvious problem like
sponginess (which we don't have) I'm not sure what I'd consider worth doing.

At the end of this crawlspace, that used to be the outside cellar door
we sealed up, you can see what may be a clue to the technique used in
the inaccessible area. There's a minor furring-type strip tacked to the
bottom of the joists, vaguely supporting fiberglass batts with raggedy
reflective barriers. (The one section between the outermost joist and
the wall has some sort of firm foam rather than a batt for no obvious
reason.)

I would not want to work in that limited space. Another option, and NOW
is the time to do it before you put down a new floor. is to take up the
subfloor, inspect, repair as needed and insulate properly.


That's basically my thinking. Vapor barrier, new insulation, perhaps a
vent? I should probably look up the code.

I did wonder about digging out a trench to extend under the cabinet area
but I'm not sure how well filling it in and installing the vapor barrier
would go. Another option, I suppose, is to just take out as much dirt
overall as is needed to allow crawling underneath. (Yech either way, of
course, and it would have to come out through the kitchen, double yech.
On the positive side I could live out my Great Escape fantasies.)

The idea of using sleepers to gain room for insulation is not going to
wear well in the future. I think you will be sorry you did not do it right.


True, I'd rather do it right, but doing it really right might be next to
impossible. There's so much with this restoration that could still be
"redone right".
