The Problem with Fiberglass Insulation in Greenville Crawl Spaces

Millions of Greenville-area homes were built with fiberglass batt insulation stapled between floor joists in the crawl space. It seemed logical at the time โ€” but in SC's humid climate, this approach fails in several critical ways:

โš ๏ธ Why Old Crawl Space Insulation Fails

Fiberglass absorbs moisture, sags, falls down, and becomes a breeding ground for mold โ€” while doing almost nothing to stop heat transfer or air infiltration.

  • Moisture absorption โ€” fiberglass soaks up humidity and holds it against wood joists, accelerating rot
  • Falling and sagging โ€” wet fiberglass loses its R-value and eventually falls, leaving gaps
  • Mold colonization โ€” damp fiberglass is a prime mold substrate
  • Pest harborage โ€” rodents, insects, and snakes nest in crawl space fiberglass
  • No air sealing โ€” fiberglass doesn't stop air infiltration, just slows conduction
  • R-value loss โ€” wet fiberglass loses up to 40% of its rated R-value

Our Insulation Services

Fiberglass Removal

Complete removal of all old, wet, or mold-contaminated fiberglass insulation. Bagged, sealed, and disposed of properly. The crawl space is left clean and ready for the next step.

Debris & Contamination Cleanup

Removal of accumulated debris, old vapor barrier material, and contaminated material before new insulation or encapsulation is installed.

Closed-Cell Spray Foam (Recommended)

Applied directly to the crawl space walls and rim joists, closed-cell spray foam provides a true air and moisture barrier with R-6.5 per inch โ€” no sagging, no moisture absorption, no gaps.

Encapsulation + Conditioned Air

When combined with full encapsulation, removing floor insulation and conditioning the crawl space is often more effective than any insulation product alone.

Fiberglass vs. Spray Foam in Greenville, SC Crawl Spaces

Old Fiberglass Batts

  • R-13 to R-19 when dry (falls in humid conditions)
  • Absorbs moisture โ€” loses R-value when wet
  • Falls from joists when saturated
  • Provides no air sealing benefit
  • Harbors mold, rodents, and insects
  • Wrong solution for Greenville's climate

Closed-Cell Spray Foam

  • R-6.5 per inch โ€” consistent in any humidity
  • Repels water โ€” zero moisture absorption
  • Adheres permanently โ€” never sags or falls
  • Complete air barrier โ€” stops infiltration
  • Rigid surface โ€” uninhabitable for pests
  • Engineered for humid climates like SC
