Is Spray Foam Insulation Worth It in Tulsa, OK?

What R-value does Tulsa need?

IECC climate zone 3, which includes most of Oklahoma, calls for R-38 to R-60 in attics and R-13 to R-20 in walls. The U.S. Department of Energy recommends roughly R-49 to R-60 in attics for most U.S. climates. Closed-cell spray foam is about R-6 per inch and open-cell is about R-3.7 per inch.

Does spray foam help with attic heat?

A Tulsa attic spray-foam source says HVAC equipment and ductwork can operate in conditioned air instead of 140-degree summer heat after installation. That can reduce strain on your cooling system in Tulsa summers.

How much does open-cell versus closed-cell cost?

Nationally, open-cell foam commonly costs $1.50 to $3.50 per square foot and closed-cell $2.50 to $6.50. In Tulsa, open-cell attic projects run about $1,900 to $5,250 and closed-cell about $2,850 to $6,650.
