Your exterior walls represent the largest surface area of your home's thermal envelope. When properly insulated with spray foam, they create an effective barrier against Oklahoma's temperature extremes—keeping you comfortable while reducing energy costs.
Whether you're building new, renovating, or upgrading an existing home, professional wall insulation is one of the most impactful improvements you can make for long-term comfort and efficiency.

Open-Cell Spray Foam
A cost-effective alternative that provides good thermal performance and excellent air sealing. Ideal for interior walls where sound dampening is desired or when budget is a primary concern.
Oklahoma Building Code Requirements
The 2021 IECC sets minimum wall insulation requirements for Climate Zone 3:
Spray foam not only meets code requirements but typically exceeds them significantly, providing better comfort and energy savings.
Benefits of Spray Foam Wall Insulation
Complete Air Sealing
Eliminates drafts by sealing around electrical boxes, pipes, and other penetrations that fiberglass can't address.
Moisture Management
Closed-cell foam prevents moisture infiltration that can lead to mold, mildew, and structural damage.
Noise Reduction
Both open and closed-cell foam reduce sound transmission from outside traffic, neighbors, and weather.
No Settling or Sagging
Unlike fiberglass, spray foam maintains its position and R-value for the life of your home.
