You are correct. Fiberglass insulation loses a considerable amount of its insulation value when exposed to even minimal moisture levels. Basements and crawlspace areas have notoriously high moisture content. And with the current problems concerning mold, any product that retains moisture is not recommended. Reflective bubble insulation is thin, has high r-values and works great in space limited areas.
