If you've been putting off insulating your Lincoln home because you're not sure what it'll cost, you're not alone. Spray foam is one of the biggest upgrades a Nebraska homeowner can make — but the pricing isn't always straightforward. This guide breaks down exactly what you can expect to pay for spray foam insulation in Lincoln, Nebraska in 2026.

Open Cell vs. Closed Cell: The Biggest Factor in Your Price
Open cell spray foam costs $1.50–$3.50 per square foot installed and delivers R-3.5 to R-3.7 per inch. It's best for attics and interior walls. Closed cell spray foam costs $3.00–$5.00 per square foot installed and delivers R-6 to R-7 per inch — nearly double. It's required for crawl spaces, basements, and exterior applications in Nebraska's humid climate.
