Is underfloor spray foam worth it in Jenks, Oklahoma?
Jenks falls under Oklahoma's 2018 IRC residential energy code with state amendments in effect since 09/14/2022. Sealing the floor with foam reduces drafts and helps meet code targets for the home's thermal envelope. Whether it pays off depends on your home's current insulation and the quote you get.
Who can install underfloor spray foam in Jenks?
Oklahoma has no statewide insulation license, so licensing, registration, and permits are handled at the city or county level. The main industry credential is the Spray Polyurethane Foam Alliance Professional Certification Program. Installer level requires 100,000 board feet sprayed; Master Installer requires 500,000 board feet plus a field exam.
What paperwork should I get after underfloor spray foam installation?
In Oklahoma, insulation installers should provide a certificate listing the installed thickness and the R-value of that thickness. It must be left in a conspicuous place in the building. Ask for it before the crew leaves.
What to do next
- Measure the crawl space or floor area in square feet so you can compare per-square-foot quotes ($1.50-$5.00 installed).
- Ask whether the quote is open-cell ($0.44-$0.73 per board foot) or closed-cell ($1.00-$2.12 per board foot).
- Verify the installer's SPFA Professional Certification Program level - Installer (100,000 board feet) or Master Installer (500,000 board feet plus field exam).
- Request the certificate listing installed thickness and R-value, which Oklahoma requires to be left in a conspicuous place.
