Crawl Space Insulation
Cold Floors? Get Crawl Space Insulation Installed
Crawl Space Insulation - When did you last thoroughly inspect your crawlspace? The quote “out of sight, out of mind” rings true. Like most people, you might have forgotten the crawlspace beneath your feet. Not maintaining the crawlspace can have negative consequences for your whole house.
A common problem is stepping on a chilly floor on a winter morning despite the thermostat operating at full power. This is a clear indication that your home requires crawlspace insulation, which involves using insulation material to maintain the temperature and quality of air inside the house.

Warm Your Cold Floors With New Insulation
Your floors feel cold because cold air is blowing under your house, and you probably don’t have adequate crawl space insulation. With open foundation vents, cold, frigid air can freely blow in under your house. The best way to warm your floors is to seal your foundation vents and insulate the walls of your crawl space.

Benefits Of Crawl Space Insulation
Enhanced Comfort
Depending on the type of insulation you have installed, an insulated crawl space can offer different benefits. Crawl space insulation eliminates the cold, drafty feeling that comes through the floors and makes the floors feel much more comfortable to the touch.
If you choose to insulate the walls with Rigid Foam Board Insulation via crawl space encapsulation, you get to enjoy several other benefits, including:
- Prevent Further Moisture Damage
- Control Mold & Fungal Growth
- Save Energy (15-20% Savings)
- Improve Indoor Air Quality
- Dry out Floor Framing
- Helps with Insects
- Peace of Mind
Improve Air Quality
Both ventilated and unventilated crawlspaces allow moisture, dust, and dirt to enter, making them a hospitable breeding ground for pests, rodents, mold, and mildew. When this happens, the quality of air inside the house degrades and can give rise to a plethora of health problems. Insulation limits moisture, pollutants, and other allergens from entering the home and thus improves the air quality inside the house.
The best insulation for air quality is rigid foam board because it does not hold contaminants like fiberglass floor insulation and does not experience “Off-Gassing” like spray foam insulation, which can leave lingering smells for years.
Improve Energy Efficiency
When moisture, dust, and dirt enter your house through the crawlspace, the HVAC system has to work harder to compensate for the change in temperature and air quality. Crawlspace insulation prevents this from happening and makes your HVAC units more efficient. This, in turn, will help you make significant savings on your energy bill.
Our rigid foam board insulation includes a ‘Radiant-Barrier’ that traps heat in the crawl space lost by the ductwork. This is where you can experience the highest energy savings and allow your HVAC systems to run more efficiently.
Materials Used In Crawl Space Insulation
Fiberglass Batt Floor Insulation
When moisture, dust, and dirt enter your house through the crawlspace, the HVAC system has to work harder to compensate for the change in temperature and air quality. Crawlspace insulation prevents this from happening and makes your HVAC units more efficient. This, in turn, will help you make significant savings on your energy bill.
Closed-Cell Spray Foam
Expanding foam is compressed in disposable cans or large containers and sprayed on the areas inside the crawlspaces that need to be insulated. It is expensive and unfortunately, it can leave behind odors, known as ‘Off-Gassing’. This musty smell can linger with the home indefinitely. Also, it’s nearly impossible to remove, which is necessary if structural repairs are ever needed. For these reasons, we do NOT recommend closed-cell spray foam in crawl spaces.
Rigid Foam Board
Rigid Foam Insulation is installed on crawlspace walls by carefully shaping the 4’x’8′ sheets of foam board and gluing them to the walls. These insulation panels are made up of a close-cell insulation design. Rigid foam costs comparatively less than spray foam and possesses an R-value equivalent to its counterpart. It is waterproof and creates a vapor barrier to prevent moisture from entering crawlspaces. It also traps heat lost from the ductwork in the crawl space, leading to energy savings.

Frequently Asked Questions
Why is crawl space insulation important?
Crawl space insulation helps maintain indoor comfort, prevents cold floors, and protects your home against drafts, energy loss, and elevated utility bills.
What are the main benefits of insulating a crawl space?
- Warmer floors and greater comfort
- Lower energy bills (up to 15–20% savings)
- Enhanced moisture control, reducing mold, mildew, and wood rot
- Improved indoor air quality by limiting dust, allergens, and pollutants
- Pest prevention by blocking entry points
- Structural protection against rot and decay
- Increased home value and HVAC lifespan.
How does insulation affect energy efficiency?
Insulation creates a thermal barrier between your crawl space and living areas, reducing heat loss in winter and heat gain in summer. This stabilizes indoor temperatures and relieves pressure on your HVAC system, saving energy and money.
What materials are used for crawl space insulation?
Common materials include:
- Rigid Foam Board: Installed on walls, waterproof, provides excellent barrier and helps trap heating from ductwork.
- Fiberglass Batt: Traditional material but prone to absorbing moisture.
- Closed-Cell Spray Foam: Insulates well but can off-gas and is hard to remove if repairs are needed; BAY does not recommend spray foam for crawl spaces due to lingering odors and removability issues.
Which insulation material is best for air quality and longevity?
Rigid foam board is considered best for crawl space walls because it does not hold mold, moisture, or off-gas like spray foam and fiberglass batts. It also adds radiant barrier benefits.
Will insulation help with pests, mold, and moisture?
Yes. Proper insulation, especially when paired with encapsulation and vapor barriers, blocks moisture entry, limits pest access, and creates an inhospitable environment for mold and mildew growth. It also helps preserve the structural integrity of wooden elements.
Can crawl space insulation improve indoor air quality?
Yes, by blocking the entry of allergens, mold spores, and pollutants, rigid foam board insulation improves the air that circulates throughout your home—especially since up to half the air in your living space can come from below.
What is the recommended insulation strategy for cold floors?
Seal foundation vents, then insulate crawl space walls with rigid foam board. This dual approach warms floors, prevents drafts, and provides year-round comfort.
What is the typical process with BAY for crawl space insulation?
- Free quote and inspection
- Expert assessment of your crawl space’s needs
