What is Crawl Space Insulation?

Crawl space insulation involves materials like foam board, fiberglass, or spray foam installed beneath your home to seal off your crawl space from the exterior elements. Along with insulation, installing a vapor barrier is also crucial. A vapor barrier covers exposed soil in the crawl space, blocking moisture from creeping into the air or dampening your insulation and rendering it ineffective.

Improved Indoor Air Quality and Healthier Living

Believe it or not, your home’s air quality depends on what’s happening in the crawl space. Driven by the stack effect, which causes warm air to rise, up to 50% of the air in your home comes from the crawl space. Adding proper insulation and a moisture barrier counteracts the stack effect, preventing unwanted moisture, mold, or pest-related problems from infiltrating your home’s air.

Beyond improving air quality and promoting healthier living, crawl space insulation offers several other benefits:

• Lower energy bills: Insulation keeps outdoor air from flowing freely into your home, reducing the load on your HVAC system and lowering your heating and cooling costs.
• Enhanced comfort: Tired of cold floors in the winter? Add crawl space insulation to keep the area beneath your home at the same temperature as the rest of the house.
• Pest prevention: Crawl spaces attract insects and rodents. Insulation and vapor barriers make it harder for these critters to invade for a cleaner, critter-free home.
• Protection against mold damage: Mold thrives in moist environments, which not only affects indoor air quality but can weaken your home’s structure. Proper crawl space encapsulation reduces moisture levels and protects your home’s foundation.

Types of Crawl Space Insulation

Several types of insulation are suitable for crawl spaces:

• Fiberglass batts are praised for their affordability, effectiveness, and ease of installation between floor joists. However, fiberglass must be handled carefully, as it can absorb moisture if the crawl space isn’t well-sealed.
• Rigid foam board is known for its high R-value, or thermal resistance, making it great for temperature control. It’s an excellent choice for crawl space walls since it naturally resists mold and doesn’t easily absorb water.
• Spray foam is a top option for maximum insulation coverage and moisture resistance. It seals even the smallest gaps, providing a barrier against temperature fluctuations and high humidity. Spray foam is more expensive than other types of insulation, but its durability and effectiveness make it a worthwhile investment.
• Encapsulation systems provide comprehensive protection by combining insulation with a vapor barrier and sealing vents and openings. Encapsulation offers long-term protection against mold, pests, and extreme temperatures.
