Where is open cell foam insulation used in Tulsa homes?
Open-cell spray foam is commonly used in wall cavities, rim joists, and attic spaces below the roof deck. It can also be a cost-effective choice for large attic volumes and interior walls. For vented attic floor applications, open-cell foam is usually sufficient and more economical.
Does Tulsa's energy code affect open cell foam insulation?
Most of Oklahoma, including Tulsa, is in IECC Climate Zone 3A. The Oklahoma Uniform Building Code Commission uses the 2021 International Energy Conservation Code with Oklahoma-specific amendments, effective November 13, 2022. Spray foam is commonly used to meet the code's R-value and air-sealing requirements.
Can open cell foam be used on an unvented roof deck in Oklahoma?
Open-cell can fill the rafter cavities in an unvented roof-deck assembly. However, closed-cell is typically required at a minimum thickness to manage vapor before open-cell fills the rest. Ask the pro which assembly fits your attic.
How does Tulsa spray foam pricing compare to national averages?
Nationally, spray foam insulation costs $1.50 to $5.00 per square foot installed, with an average project running $1,300 to $4,000. A Tulsa attic insulation guide lists spray foam attic insulation at $3,350 to $8,550. Your price depends on foam type, R-value, and project size.
