Crawl Space Repair - Fiberglass Insulation is not Always the Best Option

The first thing wrong here is the plastic facing over this insulation prevents the insulation from being able to dry when it gets wet. It will then get heavy begin to droop and eventually fall out. Fiberglass insulation is also not a good option because it has some organic material in it which allows mold to grow. No one wants mold in their home even in the crawl space.
