Still deciding best way to insulate crawl space.
* I decided that I don't want to remove old deteriorated/torn paper side down insulation-(way to much work and mess).
* I'm thinking of stapling prodex 16" or 48" to joyces under r-13 old deteriorated insulation. (On crawl space it said I would only add r-6, but taped at joints and added to my deterioated insulation I thought it would get down on some cold going through floor. My cost would only about $1100 this way.
* I still would put a thick plastic on floor-(6mill )???
* And mayby a 3/4' silver sheet glued to dirty concrete wall r-5 -- or blue 1' foam with no foil at r-5 glued to wall. Would any or all of this work? My cost total would be around $2000
