I'm considering adding more insulation to my house. It's relatively new with R-14 in the crawl space and blown-in paper-like chunks in the attic.

From the postings I've read, I'm thinking I should add unfaced rolls to the crawl rolled out perpendicular to the existing batts and held up by wire, and blow in another 4-6 inches of insulation into the attic. I think I should go with rigid foam board glued to the cinder block foundation that makes up the crawl, seal the poly on the crawl floor (it's just unrolled, not secured to anything or each strip and has holes) and maybe I should put batts in the exterior walls that are not insulated in the attic (the attic is pretty large and unfinished).

I've already caulked and sealed all the windows and doors, added "insulating covers" (small piece of foam) to every outlet and switch connected to an exterior wall and used expanding foam spray in exterior walls where drainage pipes, electrical wiring or gaps between joists and ductwork exist.

Comments are what I live for...
