Kraft-faced insulation and/or interior poly vapor retarder
Hello. Finally going to remove all my 1/4″ plywood interior walls and replace with drywall. Zone 6, high elevation snowy high desert, no A/C, heating only, Sierra Mountains California. I would like to replace the old 1970’s insulation with R15 batts and the original insulation was installed poorly.
My question is should I go with Kraft faced batts or should I go unfaced batts with poly sheeting vapor barrier? Would it be a bad idea to go with both kraft faced batts and poly sheeting? I am finding it very hard to source Rockwool or unfaced insulation in my area.
