This has to do with wall insulation in a partial re-build of a 19th cent. House in New Orleans
Climate is Deep South, or hot and very humid in the long Summer. I have heard and read that traditional batt insulation is practically useless. spray insulation is not an option !(for financial reasons) and it may, in any case, be a bad choice environmentally. Celluose . Does this product come in batt form? One further piece of info – the framing is wood on 16″ centers. What choices do I have.
Thanks, Michael Higson in New Orleans

I have wondered that myself. I found some nice, easy to install cotton batts at a company called Soundproof Cow (believe it or not) when I was looking for batts that were more effective than fiberglass.
Ecocell from cmsgreen.com is the only one I can find online.
Lucy, Thanks! Ecosell's product would work (the R-value is 20) - however, no distributor in Louisiana.
I favor the batt approach because its less messy than blown-in if, and when , modifications have to made which is often the case in a renovation of an old house.
Any other suggestions? Michael
Cellulose wall insulation in batt form will be subject to the same installation quality concerns as fiberglass batts. You need a class 1 installation with zero compression, zero voids and a full air barrier: even so the performance is unlikely to equal that of dense-pack.
