Batt fiberglass insulation between the floor joists is not recommended because it absorbs moisture. If it is installed, it needs to be covered with rigid foam board insulation, and the bard seams would need to be taped. Blown-in insulation is also not suitable for a crawl space for the same reasons. Every crawl space is different, and we would recommend working with a professional trained in crawl space insulation and encapsulation.
