Understanding Wet Crawl Space Insulation.

Crawlspace insulation is designed to help regulate temperature and improve energy efficiency throughout the home. When insulation becomes exposed to excessive moisture, it can absorb water, sag, deteriorate, and lose much of its insulating value.

Many homeowners first notice insulation hanging from the floor joists, discoloration, damp materials, or musty odors coming from the crawlspace. Wet insulation is often a symptom of a larger moisture problem that should be properly evaluated and corrected.
