How Much Does Spray Foam Insulation Cost in Oklahoma City?

Spray foam insulation in Oklahoma City 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 the area sprayed and how thick the foam needs to be.

How to Estimate Your Project

Multiply the square footage being sprayed by the thickness in inches, then by the price per board foot. For example, 1,000 square feet at 3 inches of open-cell foam is 3,000 board feet, or roughly $1,350 to $2,400. The same area at 2 inches of closed-cell foam is 2,000 board feet, or roughly $2,000 to $4,000. Remember that a roof deck is larger than the attic floor because of roof pitch.

Typical Oklahoma City Prices by Project

• 2,000 sq ft single-story house, roof deck, open-cell 5.5 in: about $5,700 to $11,400
• 20x20 garage, closed-cell about 2 in on walls and ceiling: about $2,000 to $4,000
• New construction 2x4 walls, open-cell, per 1,000 sq ft of wall: about $1,600 to $2,800
• Crawl space encapsulation with liner and dehumidifier: about $5,000 to $15,000
• New spray foam roof with coating: about $4.00 to $7.00 per sq ft
• 40x60 metal building, closed-cell about 2 in: about $10,000 to $20,000

What Moves the Price

Foam type and thickness matter most, followed by total area and access. Removing old insulation typically adds about $0.75 to $2.00 per square foot, crawl spaces may need drainage work first, and occupied commercial spaces may need a fire-rated coating. Rim joist sealing is one of the best-value add-ons, often a few hundred dollars on an attic or crawl space project.

Is Spray Foam Worth It in Oklahoma City?

Spray foam pays off most where air sealing matters: attics with ductwork, rooms over garages, crawl spaces, metal buildings and flat commercial roofs. For a simple open attic floor without ducts, blown-in insulation is often the better value, and we will tell you if that is the case.
