His builder suggests removing the fiberglass batts already installed in the floor and sealing leaks with tape and caulk before re-insulating. He could re-use the fiberglass insulation, combined it with a thin layer of sprayed in polyurethane foam or skip the fiberglass altogether and add a thicker layer of foam.
There are a couple of complicating factors, chief among them Martin's concern the sprayed foam will exacerbate existing chemical sensitivities.
He looks for suggestions at GreenBuildingAdvisor's Q&A forum, and the discussion is the topic of this week's Q&A Spotlight.
