Jenks, OK: what's different here
Jenks sits about 11 miles and roughly 15 minutes from Tulsa via US Route 75, so local contractors serve the area regularly. Jenks falls in Oklahoma's Climate Zone 3, where the code calls for R-38 ceilings and R-15 walls. The state's current residential energy code status is the 2018 IRC, effective statewide since November 13, 2022.
What R-value should a Jenks attic have?
Oklahoma's residential energy code status is the 2018 IRC. Climate Zone 3 prescriptive ceiling insulation is R-38, while Climate Zone 4 ceilings require R-49. Use these code-minimum levels as the baseline for a drafty-room upgrade.
How long does drafty room insulation take to install?
Most residential spray-foam style projects take 1 to 3 days. Crawlspaces and attics are usually completed in a single day. ENERGY STAR rates a DIY attic job as moderate to difficult and also estimates 1 to 3 days.
What does spray foam cost in the Tulsa area?
A Tulsa cost estimate for a standard spray foam project shows 1,282 square feet at a total of $2,031 to $2,537, with 14.8 hours of labor. Published spray-foam attic price ranges run from $1,100 to $9,000. Roof-deck or rafter applications are commonly listed at $1,500 to $9,000.
Do Jenks walls and slabs have code requirements too?
Climate Zone 3 wood-frame walls call for R-15, while Climate Zone 4 walls require R-30 or R-20+5ci or R-13+10ci or R-20ci. Climate Zone 4 slab insulation requires R-10ci for 3 feet, but Climate Zone 3 has no slab requirement. Oklahoma's statewide codes became effective November 13, 2022.
What to do next
- Check which climate zone your Jenks home falls in and compare your attic against the R-38 ceiling minimum.
- Ask each contractor for a per-square-foot quote and confirm it falls within the $1.50 to $5.00 installed range.
- Request proof of insurance and any state or city licence before work starts.
- Ask whether your project is a one-day attic or crawspace job or a 1-to-3-day whole-room project.
