Crawl spaces are prone to moisture issues, temperature fluctuations, and air leaks. Insulating this area helps to create a more stable and comfortable living environment by preventing cold floors, reducing energy loss, and mitigating moisture-related problems such as mold and mildew.
Properly insulating your crawl space is crucial for maintaining your home's energy efficiency, preventing moisture problems, and improving indoor air quality. Here’s a detailed guide to help you insulate your crawl space effectively.
Use: SmartSHIELD 10MM, SmartSHIELD 5MM, SmartSHIELD 1/4 Inch, or SmartSHIELD 20MM
How To Insulate A Crawl Space
Installing on Crawl Space Ceiling (3 methods)
A: Staple or screw SmartSHIELD under floor joist. Tape seams with reflective tape.
B: Depending on joist spacing, staple, or screw SmartSHIELD between joists 2' to 4' below floor board. Tape seams with reflective tape.
C: Combine method A and B to maximize performance.
Installing Crawlspace Wall Insulation:
Use double sided tape to attach SmartSHIELD to concrete wall.
Installing Crawlspace Wall Floor
Roll out SmartSHIELD Reflective Insulation on crawlspace floor - White side down facing dirt. Overlap insulation by 3 inches and tape seams with reflective tape.
Finishing Touches
- Install Vapor Barrier: Cover the entire crawl space floor with a vapor barrier, extending it up the walls and securing it with tape or adhesive.
- Inspect and Maintain: Regularly check the insulation and vapor barrier for signs of damage or moisture. Address any issues promptly to maintain effectiveness.

Due to the underground environment, moisture and cold are the primary considerations in developing a crawl space insulation strategy. Excess moisture can cause mold, mildew, odors, decay, fungus growth and wood rot. Cold temperatures below will increase your energy costs and make it less comfortable to walk on your floor.
The underground environment of a crawl space presents unique challenges. The moisture content in soil below three feet deep is almost always higher than the moisture content of the air inside. This difference in vapor pressure causes moisture to be driven from the soil into the crawl space interior by diffusion through the wall. A significant amount of moisture from the soil below the slab will wick upward into the crawl space. SmartSHIELD Reflective Insulation, vapor barrier crawl space insulation, solves your moisture and thermal protection needs.
Challenges To Insulating A Crawl Space
- The Soil below your home
- Hydrostatic pressure against the foundation wall from rainfall, snow melt or irrigation creates exterior diffusion
- Air infiltration bringing moisture in.
- Groundwater leakage through the foundation
- Interior diffusion from humidity in warm indoor air
- Condensation formed due to temperature differences between ground and wall
Underground soil temperatures can be much colder than either the outside air or the indoor air. The warmer the air of the basement constantly expands. When this warm air reaches the cooler surface of a wall next to the ground, condensation will occur on the interior of the wall. Any insulation in your crawl space will be subject to potentially large amounts of moisture driven from both the exterior and the interior depending on the season.
Air infiltration can be a major source of moisture entering your crawl space. A lot more water vapor can move through a very small opening where the vapor pressure is greater on the exterior than can move through the wall surface by diffusion. Air-transported moisture can quickly lead to mold, mildew and decay in interior wall assemblies. Properly insulating a crawl space requires addressing all these challenges.
Fiberglass insulation should not be used in a crawl space! To maintain its thermal effectiveness, fiberglass insulation cannot be exposed to moisture. Moisture will degrade the insulation R-value of fiberglass batts and promote mold and mildew. Installing a vapor barrier over the interior of fiberglass insulation will not prevent the foundation walls from drying to the interior, migrating capillary rise and ground water leakage. Batts with no vapor barrier will not be effective either as
interior humidity will still cause loss of insulation R-value. U. S. Department of Energy: The R-value of some insulations also depends on...moisture accumulation.

SmartSHIELD Reflective Insulation crawlspace insulation does not support mold, mild or fungus growth. It does not lose thermal effectiveness when wet.
Your home can act like a vacuum drawing radon up through the crawlspace in two ways. First, the air pressure inside is usually lower than pressure in the soil around the foundation. Second, warm air will rise to leak out creating a small amount of suction that can pull radon gas up through the crawlspace. A poorly
insulated crawlspace can account for 15 percent or more of a building's total heat loss. SmartSHIELD is most effective against downward radiant heat transfer making it a builder's choice for crawlspaces as a radiant barrier. Heat radiating downward from your floor into the crawlspace will be reflected back inside, saving energy and maintaining constant room temperatures. The most recent advance in crawlspace insulation is SmartSHIELD Reflective Insulation as a vapor barrier, radon barrier and insulation combined in one product.
Components Of The Best Crawl Space Insulation
- Keep your floors noticeably warmer
- Reduce air infiltration and drafts
- Save energy and money by keeping heat and air conditioning inside
- Minimize problems with condensation, wood rot, mold and mildew
- Provide waterproofing
- Seal entry paths against termites
- Control radon infiltration
Insulating your crawl space is a vital step in improving your home's energy efficiency, comfort, and overall health. By choosing the right insulation materials and following proper installation techniques, you can effectively insulate your crawl space and prevent common problems associated with this area. Regular maintenance and inspections will ensure the insulation remains in good condition, providing lasting benefits.
