A properly insulated crawl space can make a world of difference in your building’s comfort, air quality, and energy efficiency.

Why Crawl Space Insulation Is Essential
If your crawl space is poorly insulated—or not insulated at all—you could be losing a significant amount of conditioned air, allowing moisture buildup, and creating an ideal habitat for pests and mold. The crawl space is often overlooked, but it’s a critical part of your home or building’s thermal envelope.
Insulating this area can:
- Reduce energy costs by preventing heat loss through the floor
- Control moisture to help prevent mold, mildew, and wood rot
- Improve indoor air quality by blocking allergens and pollutants
- Deter pests by sealing entry points and creating a cleaner environment
- Increase comfort by stabilizing indoor temperatures year-round
Whether you own a home or operate a business in Nashville, insulating your crawl space is one of the smartest upgrades you can make to improve the performance and longevity of your property. It’s especially important to insulate crawl space for energy efficiency and create a healthier indoor environment.
Types of Crawl Space Insulation We Offer
At Complete Insulation, we offer custom crawl space insulation services to match the unique structure and needs of your space. We primarily work with two types of insulation that are well-suited for crawl space environments:
Spray Foam Insulation
Spray foam insulation is one of the best crawl space insulation options available. Applied as a liquid that expands into a solid foam, it seals every crack and gap to create a powerful thermal and moisture barrier. Closed cell spray foam is especially effective in crawl spaces thanks to its:
- High R-value for exceptional thermal resistance
- Air and moisture sealing properties to prevent mold and mildew
- Durability that lasts for decades without sagging or settling
- Structural reinforcement that can help support your floor joists
If your crawl space is prone to dampness or if you’re looking for long-term performance, spray foam is often the best solution.
Fiberglass Insulation
We also offer fiberglass batt insulation as a cost-effective alternative for crawl space applications. While it doesn’t offer the same level of moisture resistance as spray foam, it still provides:
- Strong thermal protection
- Noise reduction
- Affordability for budget-conscious projects
In both options, we may recommend pairing the insulation with a vapor barrier crawl space insulation system for added moisture protection.

Frequently Asked Questions (FAQs) About Our Crawl Space Insulation
Why Is Crawl Space Insulation So Important in Tennessee?
Tennessee’s hot, humid summers and cool winters make crawl spaces vulnerable to temperature fluctuations and moisture issues. Proper insulation helps prevent mold, improve comfort, and reduce HVAC strain—especially in older buildings that weren’t originally built with insulation in this area.
Should I Insulate the Crawl Space Floor or the Walls?
It depends on your crawl space design. In ventilated crawl spaces, insulating the subfloor is common. In sealed or conditioned crawl spaces, insulating the walls with spray foam is more effective for controlling temperature and humidity.
Can Fiberglass Insulation Be Used in Crawl Spaces?
Yes, but only in dry, well-ventilated crawl spaces. It’s important to use faced batts and install a vapor barrier crawl space insulation system to minimize moisture issues. Spray foam is generally preferred for its superior moisture resistance.
How Long Does Spray Foam Insulation Last in a Crawl Space?
Spray foam insulation can last 30 to 50 years or more when professionally installed. It doesn’t settle or degrade over time, providing long-term performance without the need for frequent maintenance.
Is Crawl Space Insulation Worth the Investment?
Absolutely. The energy savings, improved indoor air quality, and protection against moisture-related damage make it a cost-effective upgrade that pays off over time—especially when installed by professionals like Complete Insulation.
