The cost to insulate a crawl space depends on the insulation type, size of the crawl space, and labor costs. Fiberglass insulation typically costs $0.60–$1.30 per square foot for materials alone. Including labor, the total cost ranges from $1.50–$3.50 per square foot. Spray foam and rigid foam boards cost more, averaging $3.50–$7.00 per square foot.
Crawl space insulation costs vary widely, with an average range of $500–$4,500 for most residential projects. Smaller projects using fiberglass may cost as little as $500–$1,500, while larger or more complex projects using spray foam can exceed $3,000.
R13 and R15 insulation differ slightly in thermal resistance. R15 has a higher R-value, making it more effective at reducing heat transfer. Both are suitable for walls and floors in mild climates, but R15 provides better energy efficiency and may be required in areas with stricter building codes. For crawl spaces, R15 is a better choice for slightly improved insulation performance.
