Oklahoma Code Requirements for Basement Wall Insulation
Oklahoma code compliance for basement wall insulation depends on the climate zone. In Climate Zone 3, the prescriptive requirement is R-13 or R-5 continuous insulation. The Oklahoma Residential Code 2018 directs that walls associated with unconditioned basements must comply with these requirements unless the floor overhead is insulated under specified code sections.
Cost Estimates for Tulsa Basement Wall Insulation
A Tulsa cost estimate for a standard spray foam project shows a total cost between $2,031 and $2,537 for 1,282 square feet. This estimate also lists the labor time required for the installation. HomeGuide lists the average installed cost of spray foam insulation between $1,300 and $4,000.
Climate Zone Considerations for Tulsa Insulation
Most of Oklahoma, including Tulsa, is classified as IECC Climate Zone 3A. While the warm-humid region of Zone 3 is generally not required to be insulated, the state energy code mandates that basement walls meet specific insulation provisions where applicable. The energy certificate must list the predominant R-values installed in these components.
Insulation Options and R-Values
Compliance allows for either R-19 cavity insulation on the interior or a 15/19 path using R-13 cavity insulation plus R-5 continuous insulation. For Climate Zone 3, the prescriptive requirement is R-13 or R-5 continuous insulation. For Climate Zone 4, the requirement is R-13 or R-10 continuous insulation.
