Crawl space insulation refers to the process of insulating the area beneath your home—called a crawl space—to improve energy efficiency, moisture control, and overall indoor comfort. Crawl spaces are typically found in homes that don't have basements and are raised a few feet off the ground.


Types of Crawl Spaces


There are two main types:

  1. Vented crawl space – has vents to the outside.
  2. Unvented (sealed) crawl space – completely sealed from outside air and moisture.


Common Insulation Materials


  • Foam board insulation (rigid panels)
  • Spray foam insulation
  • Fiberglass batts (not ideal in damp environments)
  • Encapsulation systems (include vapor barriers and dehumidifiers)


Benefits of Crawl Space Insulation


  • Energy Efficiency
  • Prevents heat loss in winter and keeps your home cooler in summer.
  • Can reduce HVAC workload and lower energy bills.
  • Moisture Control
  • Insulation combined with vapor barriers helps reduce moisture, which prevents mold and mildew.
  • Improved Air Quality
  • Since air from crawl spaces can circulate through your home, controlling contaminants improves indoor air quality.
  • Structural Integrity
  • Helps prevent wood rot and damage caused by excess moisture.
  • Comfort
  • Floors feel warmer in winter and less drafty.
  • Pest Prevention
  • Sealing and insulating crawl spaces can help keep out insects and rodents.
