If you are searching for a trusted spray foam insulation contractor in Oklahoma City, you are in the right place. Bo's Insulation has been installing open-cell and closed-cell spray foam throughout the OKC metro for over eight years, earning a perfect 5.0-star rating across every review platform. We specialize exclusively in existing homes, so we understand the unique challenges that older Oklahoma homes present — from inadequate insulation to persistent air leaks that drive up your utility bills month after month.

Spray foam insulation is the only insulation material that insulates and air seals at the same time. Unlike traditional fiberglass batts or loose-fill cellulose, spray foam expands on contact to fill every crack, gap, and void in your walls, attic, and crawl space. For homeowners across Oklahoma City, Edmond, Norman, Moore, and the surrounding metro, that means dramatically improved comfort and energy savings that you can feel on your very first utility bill.

Open-Cell vs. Closed-Cell Spray Foam

Understanding the difference between open-cell and closed-cell spray foam is essential for choosing the right product for your home. Both types are sprayed as a liquid and expand into a solid foam, but they serve different purposes and perform differently in Oklahoma's climate.

Open-Cell Spray Foam

Open-cell spray foam has a lighter, sponge-like structure. The tiny cells in the foam are not completely closed, which makes the material softer and more flexible. It delivers an R-value of approximately R-3.7 per inch, which is still significantly higher than fiberglass batts. Open-cell spray foam excels at sound dampening, making it a popular choice for interior walls, attic floor lines, and bonus rooms above garages. It is also the more affordable option, typically costing between $1.50 and $2.50 per square foot installed in the Oklahoma City area.

For most OKC attics, open-cell spray foam applied to the underside of the roof deck is an outstanding solution. It creates a sealed, conditioned attic space that keeps your HVAC system running efficiently even during those brutal July days when temperatures outside push past 105 degrees.

Closed-Cell Spray Foam

Closed-cell spray foam is denser and more rigid. Its cells are fully closed and packed tightly together, which gives it a higher R-value — approximately R-6.5 per inch — and makes it an effective moisture and vapor barrier. Closed-cell foam also adds structural strength to walls and rooflines. In Oklahoma City, where severe weather is a fact of life, that added rigidity can be a genuine benefit.

We typically recommend closed-cell spray foam for crawl spaces, rim joists, and any area that is exposed to moisture or ground contact. It costs between $2.50 and $4.00 per square foot, but the added moisture protection and higher R-value per inch make it the better investment in those specific applications. Homeowners in Midwest City, Del City, and other areas with older pier-and-beam foundations particularly benefit from closed-cell foam in their crawl spaces.

R-Values and What They Mean for Your Oklahoma Home

R-value measures an insulation material's resistance to heat flow. The higher the R-value, the better the insulation performs. The U.S. Department of Energy recommends that homes in Oklahoma — which falls in Climate Zone 3 and Zone 4 — maintain at least R-38 in attics and R-13 to R-15 in exterior walls. Many older homes throughout Oklahoma City, Yukon, Mustang, and the surrounding suburbs fall well short of these standards.

With closed-cell spray foam at R-6.5 per inch, you can achieve R-19.5 in just three inches of wall cavity. With open-cell foam at R-3.7 per inch, a standard 2x4 wall cavity filled to 3.5 inches delivers R-13. In attics, we can spray either product to whatever thickness achieves your target R-value, and because spray foam does not settle or compress over time, that R-value stays consistent for the life of your home.

Best Applications for Spray Foam in OKC Homes

  • Attic insulation — spray the roof deck to create a sealed, conditioned attic that dramatically reduces energy loss
  • Crawl spaces — closed-cell foam seals out moisture and pests while insulating the floor above
  • Rim joists — the single most common area for air leakage in Oklahoma homes, and spray foam is the most effective solution
  • Bonus rooms and knee walls — open-cell foam keeps rooms above garages comfortable year-round
  • Basement walls — closed-cell foam provides insulation and moisture protection for below-grade walls
  • Cathedral ceilings — spray foam is often the only practical insulation option for vaulted or cathedral ceilings

Benefits of Spray Foam Insulation

  • Insulates and air seals simultaneously — no need for a separate air sealing step
  • Highest R-value per inch of any common insulation material
  • Reduces heating and cooling costs by 30-50% in most Oklahoma City homes
  • Does not settle, sag, or lose performance over time
  • Closed-cell foam acts as a moisture and vapor barrier
  • Reduces outdoor noise penetration by up to 60%
  • Discourages pests — rodents and insects cannot nest in spray foam
  • Lasts the lifetime of your home — 50+ years with no maintenance
  • Can qualify for OGE utility rebates and federal energy tax credits

Our Spray Foam Insulation Process

When you call Bo's Insulation for spray foam insulation in Oklahoma City, here is exactly what to expect. First, we schedule a free on-site estimate at your convenience. One of the Bohannan brothers will personally inspect your home, measure the areas that need insulation, and recommend the right type and thickness of spray foam for your situation. We explain everything clearly, answer your questions, and provide an honest, competitive quote with no hidden fees.

On installation day, our crew arrives on time and prepares the work area by masking off surfaces that should not be sprayed. We set up ventilation equipment to ensure proper air circulation during the application. The spray foam is applied in thin passes, building up to the required thickness. It expands and cures within seconds, filling every crack and void. Most residential spray foam projects in the OKC metro are completed in a single day.

After installation, we do a thorough cleanup and walk you through the finished work. You will notice a difference in your home's comfort within hours, and when your next utility bill arrives, you will see real savings.

What is the difference between open-cell and closed-cell spray foam?

Open-cell spray foam is lighter, more flexible, and more affordable. It offers about R-3.7 per inch and excellent sound dampening. Closed-cell foam is denser, delivers about R-6.5 per inch, and doubles as a moisture barrier. For most Oklahoma City homes, we use open-cell in attics and interior spaces, and closed-cell in crawl spaces and areas exposed to moisture.

How long does spray foam insulation last?

Spray foam insulation lasts the lifetime of your home — typically 50 years or more. Unlike blown-in insulation, spray foam does not settle, sag, or lose R-value over time. Once it is installed, it maintains peak performance indefinitely with zero maintenance.

Is spray foam insulation worth the higher cost?

For most Oklahoma City homeowners, absolutely. Spray foam seals air leaks and insulates in one step, which typically reduces energy bills by 30-50%. Most of our customers recoup the cost difference within 3-5 years through lower utility bills. Plus, spray foam never needs to be replaced or topped off, unlike other insulation types.
