 o
crawl space insulation

Posted by fritzgarden (My Page) on

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?

RE: crawl space insulation

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!
