Crawl Space Insulation - Falling Fiberglass

Fiberglass has fallen from the floor joists in the crawl space. Many of the pieces still clinging on are being pulled apart by moisture in the air. Moisture will deteriorate the fibers, tearing the fiberglass apart. Water that is soaked up will cause the fiberglass to become heavy and sag and eventually gravity will pull them down to the floor, littering the crawl space with debris and material. This insulation is rendered useless and will either need to be replaced or removed.
