How Much Does Spray Foam Insulation Cost in Okmulgee? A Local Price Guide

Spray foam insulation in Okmulgee typically costs about $0.45 to $0.80 per board foot installed for open-cell foam and about $1.00 to $2.00 per board foot for closed-cell foam. A board foot is one square foot of surface at one inch thick, so the total depends on how much area you spray and how thick the foam needs to be.

How to Estimate Your Project

Multiply the square footage of the surface being sprayed by the planned thickness in inches. That gives you board feet. Then multiply by the price per board foot. For example, 1,500 square feet of attic roof deck at 5.5 inches of open-cell foam is 8,250 board feet, or roughly $3,700 to $6,600. The same math works for walls, crawl space walls and metal buildings.

Typical Okmulgee County Prices by Project

• Attic roof deck, about 1,500 sq ft, open-cell 5.5 in: about $3,700 to $6,600
• Crawl space walls and rim joists, closed-cell about 2 in: about $1,500 to $3,500 for a typical home
• Full crawl space encapsulation with liner and dehumidifier: commonly $5,000 to $15,000
• 30x40 pole barn or shop, closed-cell about 2 in on walls and roof: about $5,500 to $11,000
• 40x60 metal building at the same thickness: about $10,000 to $20,000
• Barndominium living area, about 2,000 sq ft: about $12,000 to $25,000
• Spray foam roofing with coating: about $4 to $7 per square foot

What Moves the Price Up or Down

The biggest factors are foam type and thickness, total area, and access. Steep or cut-up roofs, tight crawl spaces and tall metal buildings take more time. Removing old or damaged insulation adds cost, typically about $0.75 to $2.00 per square foot. Some commercial or occupied spaces also require a fire-rated coating over the foam, which is quoted separately.

Open-Cell or Closed-Cell?

Open-cell foam costs less and is a strong choice for attic roof decks and interior walls. Closed-cell foam costs more but resists moisture, adds strength and packs about R-6 to R-7 per inch, which is why it is the standard for crawl spaces, metal buildings, pole barns and barndominiums. Many projects use both. See Closed Cell vs Open Cell Spray Foam for a deeper comparison.
