Jenks, OK: what's different here
Jenks is a fast-growing suburban city in Tulsa County with a population of 26,017 at the 2020 census. It sits about 11 miles from Tulsa, roughly a 15-minute drive via US Route 75. Many homes there have vaulted ceilings that need insulation meeting Oklahoma's energy code. The statewide codes in use took effect November 13, 2022.
What R-value does code require for ceilings in Jenks?
Jenks sits in Tulsa County, and Oklahoma code references list Climate Zone 3 ceilings at R-30, with Climate Zone 4 ceilings listed at R-38 or R-49 depending on the code document. One current reference lists a minimum of R-19 for ceilings in Climate Zones 1 through 4. Ask your contractor which zone and R-value apply to your home.
Is spray foam required for unvented vaulted ceilings in Oklahoma?
No. Oklahoma's code language allows unvented attics to be built by installing fiberglass or mineral wool insulation below the roof deck instead of spray foam. That said, spray foam is a common option homeowners consider for vaulted assemblies.
How long does vaulted ceiling insulation take?
A 2-person crew can typically install 1,000 square feet of batt-and-roll insulation in 4 to 5 hours, so the insulation portion is often a same-day task. Full ceiling installation or replacement can take 1 to 3 days. Complex jobs like vaulted ceilings take more labor, which raises cost.
Where do I find the R-values listed for my home?
Oklahoma requires insulation R-values to be listed on the energy code sheet, a one-page document with insulation and fenestration information. The code certificate for your home must also list the predominant R-values in the ceiling/roof, walls, foundation, and ducts outside conditioned spaces.
What to do next
- Check your home's energy code sheet or code certificate for the R-values listed for your ceiling and roof.
- Ask each contractor which climate zone and ceiling R-value (R-30, R-38, or R-49) applies to your Jenks home.
- Get a written quote showing cost per square foot, material, and target R-value before work starts.
- Ask the contractor for proof of insurance and any license Oklahoma or Jenks requires.
