Bixby, OK: what's different here
Bixby sits about 18 miles from Tulsa, roughly a 29-minute drive by the main highway. Census data from 2019-2023 shows 84.9% of residents stayed in the same house for a year, pointing to a stable housing stock. Oklahoma builds to the 2021 International Energy Conservation Code with state amendments, effective November 13, 2022. Attic and wall upgrades in the area are often sized around R-30 to R-49 ceilings.
How much does open cell foam insulation cost per square foot?
At common thicknesses, open cell spray foam runs roughly $1.54-$2.56 per square foot for 3.5 inches of insulation. HomeGuide lists spray foam overall at $1.50-$5.00 per square foot installed, depending on foam type, R-value, and project size. Average whole-project costs run $1,300-$4,000.
What R-values does the Oklahoma energy code require?
The Oklahoma residential energy code summary requires R-30 ceilings in Climate Zone 3 and R-49 in Zone 4, plus wall values like R-15 in Zone 3. Crawl space walls call for R-13 or higher continuous equivalents. Slab insulation has no Zone 3 requirement but needs R-10ci for 3 feet in Zone 4.
How long does a spray foam installation take?
A small basement takes 2-3 hours and a large attic 6-8 hours. An entire house takes 3-4 days. Most homes are done in one to two days.
Why does open cell foam expand quickly?
Open cell spray foam expands rapidly, with full expansion occurring in 60-90 seconds. That fast expansion lets it fill cavities quickly. It is commonly priced by the board foot, which makes comparing attic and whole-home quotes easier.
What to do next

- Confirm your climate zone targets: R-30 or R-49 ceilings and R-15 or higher walls per the Oklahoma code summary.
- Request proof of insurance from the contractor before work starts.
- Ask how long your project will take, whether 2-3 hours for a small space or 3-4 days for a whole house.
