The house I just moved into has a crawlspace and NO insulation between
the floor joists. With gas heat as expensive as it is now, I want to
install the insulation that SHOULD have been there in the first place.
Does the paper backing on the insulation go up against the underside of
the floor, or down, so I'm looking at it has I install it from inside
the crawl space?
Also, since the joists are 2x12's, should I get 12" thick insulation?
Thanks - just trying to do it right the first time.
I think Chub was right - paper towards the living space, which means UP
in your case. If you can put 12" of insulation, go for it. If it's a
dirt crawlspace, you'll want to put some sort of moisture barrier
between the dirt and your house too.
I can put 12" of insulation there, but w/ the paper up (as I gather it
should be), that would mean having to push
my stapler (and my hand) up through the insulation. do the wire braces
you buy and just 'stuff' between the joists work well in this case, or
are they more for dryer environments like attics, etc.
also, there is black plastic on the ground inside the crawlspace - so
the builder did SOMETHING right.
thanks for all the replies,
Sorry, vapor barrier towards the warm side. Unless you are in Florida
or south you put the vapor barrier towards the living area, in this case up.
You use the metal wires made to hold the stuff up there for this
