Broken Arrow, OK: what's different here
Broken Arrow is located in Tulsa County, Oklahoma. Homes in the area fall under climate zone 3 codes. Local energy-code guidance for this zone specifies R-38 for attic insulation. Basement wall insulation requirements may vary based on the home's location regarding warm-humid zones.
Code Requirements for Ceiling Insulation in Tulsa
The Oklahoma Ceiling Insulation Rebate Program requires finished attic insulation to reach at least R-49 to qualify for the rebate. Spray foam insulation can only qualify for this rebate if it is installed by a licensed professional installer. The rebate offers varying amounts based on the R-value achieved, starting at $250 for R-15 to R-22.99.
Comparing Installation Speed and Cost
Blown fiberglass is generally the lower-cost and faster option for accessible attics, with typical installed costs around $1.00 to $2.00 per square foot. Spray foam insulation is more expensive, ranging from $1.50 to $6.00 per square foot, but it offers superior air sealing and moisture control.
Performance of spray foam insulation vs. fiberglass
Open-cell spray foam provides an R-value of about R-3.5 to R-3.7 per inch, which is higher than blown-in fiberglass at R-2.2 to R-2.7 per inch. While fiberglass is a common choice for unvented attics, spray foam is better when maximizing R-value per inch is the priority.
Local Building Code Guidelines for Broken Arrow
Oklahoma residential energy-code guidance for climate zone 3 lists attic insulation at R-38 prescriptively, with R-49 being the higher ceiling option. Wood-frame wall insulation in this zone is listed at R-15, or alternatives like R-13+10ci and R-20ci.
