crawl space insulation

fritzgardenDecember 8, 2009

we have a small crawl space of around 22x8 with a varied depth of 6" to 18".

It's in the south end of the house and is quite cold in winter.

I'm thinking about blow in cellulose or Cementitious foam/Air Krete.

The floor is old hardwood that I'm quite reluctant to pull up to build a "contained" space in between the joists.

Has anyone any ideas for a very partial pull up that might allow the building of a such a "contained" space for the Air Krete or cellulose to fill?

Thank you for reporting this comment. Undo

Instead of trying to fill in all that space, consider insulating from the outside with 2 ins. of XPS or 4 ins. of EPS foam boards with a protective covering above-grade. First, assuming you can at least get some access, cover the soil in the crawlspace with a min. 6 mil poly. Don't get stuck!
