This house is in the deep south. The ducts in the crawlspace were recently wrapped with the insulation shown to help with a condensation problem. I don’t know how bad it was before but you could wipe water off this insulation and there were puddles below. The insulation had a label saying it provided an R 8 with an air space and an R 4 without. The insulation was double wrapped so it should have the minimum recommended which is an R 8. I’m thinking a thick well wrapped fiberglass bat would provide a higher R factor and take care of the problem. Has anyone else seen problems with this insulation in the crawlspace?
