The most affordable and versatile way to insulate your OKC home. Cellulose and fiberglass blown-in insulation fills every gap for complete coverage.
Blown-in insulation is the most popular insulation upgrade for existing homes in Oklahoma City, and for good reason. It is affordable, versatile, and fast to install. Using specialized blowing equipment, loose-fill insulation material is distributed evenly throughout your attic or wall cavities, filling around every joist, pipe, wire, and obstacle to create a seamless thermal barrier. Bo's Insulation has installed blown-in insulation in hundreds of homes across the OKC metro, from century-old bungalows in Mesta Park to 1990s-era homes in Moore and Edmond, and our perfect 5.0-star rating reflects the quality of work we deliver on every single project.
For Oklahoma City homeowners looking for the best value in insulation, blown-in is hard to beat. At $1.00 to $2.50 per square foot, it costs significantly less than spray foam while still delivering substantial energy savings. Most blown-in insulation projects are completed in just a few hours, meaning you can schedule the work in the morning and start feeling the difference by afternoon. Whether you live in Yukon, Mustang, Midwest City, Del City, or anywhere else in the Oklahoma City area, blown-in insulation is an investment that pays for itself through lower energy bills — often within the first one to two years.
We install both cellulose and fiberglass blown-in insulation, and each material has distinct advantages depending on your home's needs and conditions. Understanding the differences will help you make an informed decision, and our team is always happy to walk you through the specifics during your free estimate.
Cellulose insulation is manufactured from recycled paper products — primarily newsprint — that are shredded, fiberized, and treated with borate-based fire retardants and pest deterrents. The result is a dense, gray insulation material that packs tightly and resists air movement through its mass. Cellulose delivers approximately R-3.5 per inch and is one of the most environmentally friendly insulation options available, containing roughly 80% recycled content.
For Oklahoma City attics, cellulose is an excellent choice. Its density helps it resist the convective air currents that can reduce the effectiveness of lighter insulation materials during extreme temperature differences — something OKC homeowners deal with regularly when it is 15 degrees outside and 70 degrees inside. Cellulose also provides better sound dampening than fiberglass, which homeowners in noisier neighborhoods throughout Oklahoma City and its suburbs appreciate.
The borate treatment in cellulose insulation serves double duty: it makes the material fire-resistant and also deters insects, rodents, and mold. In a region like central Oklahoma where pests can be a persistent issue, that built-in protection is a meaningful advantage.
Fiberglass blown-in insulation consists of tiny glass fibers that trap air pockets to resist heat transfer. It delivers approximately R-2.5 to R-3.2 per inch — slightly less than cellulose — but comes with its own set of advantages. Fiberglass does not absorb water, so if your attic has occasional humidity or condensation issues, fiberglass will maintain its performance while cellulose could be compromised. Fiberglass is also inherently non-combustible, meaning it requires no chemical fire retardant treatments.
Fiberglass blown-in insulation is the lighter of the two materials, which can be a consideration in older OKC homes where adding excessive weight to ceiling structures is a concern. It also tends to settle less than cellulose over time, maintaining a higher percentage of its initial installed depth.
The installation process for blown-in insulation is straightforward and efficient. Here is how we do it at Bo's Insulation:
For attic applications: Our crew sets up the blowing machine outside your home and feeds bags of insulation material into the hopper. A long, flexible hose carries the material into your attic, where one of our team members directs the flow evenly across the attic floor. We install depth markers throughout the space so we can verify even coverage and the correct insulation depth to achieve your target R-value. Before blowing any insulation, we first seal air leaks around common penetration points — pipes, wires, recessed light housings, and the attic hatch — because air sealing and insulation work together for maximum effectiveness.
For wall applications: Dense-pack blown-in cellulose can be installed in existing wall cavities without removing drywall. We drill small holes — typically 2 to 3 inches in diameter — in the exterior siding between each wall stud bay. A fill tube is inserted through the hole, and insulation is packed tightly into the cavity from bottom to top. After filling, we plug and patch the holes to match the existing siding. This technique works well on many homes throughout Norman, Edmond, and older Oklahoma City neighborhoods, though for walls we often recommend comparing this approach with injection foam insulation, which provides superior air sealing.
One of the most common questions we hear from Oklahoma City homeowners is whether blown-in insulation settles over time. The honest answer is yes — all blown-in insulation settles to some degree. Cellulose typically settles approximately 15-20% within the first year after installation, then stabilizes. Fiberglass settles less, usually around 5-10%.
At Bo's Insulation, we account for settling by installing blown-in insulation to a depth that exceeds the target R-value, ensuring that even after settling, your insulation meets or exceeds the recommended level. For example, if we are targeting R-49 with cellulose (which requires about 14 inches after settling), we will install to approximately 17 inches initially.
Beyond settling, blown-in insulation requires virtually no maintenance. You should avoid storing heavy items on top of insulation in your attic, as compression reduces its effectiveness. If you notice areas where insulation has been displaced — perhaps from a plumber or electrician working in the attic — give us a call and we can top it off quickly and affordably.
Blown-in insulation is the most budget-friendly insulation option for OKC homeowners. Here is what you can expect to pay in the Oklahoma City area:
These are general ranges — your actual cost depends on the size of the area, the target R-value, accessibility, and whether old insulation needs to be removed first. Bo's Insulation provides free, detailed estimates so you know the exact cost before any work begins.
When you choose Bo's Insulation for blown-in insulation in Oklahoma City, here is what to expect. We start with a free home inspection where we measure your existing insulation, identify air leaks, and assess the overall condition of your attic or walls. We then recommend the best material and target R-value for your situation and provide a clear, written estimate.
On installation day, we begin by sealing air leaks in the attic floor — this critical step is included with every attic insulation project and maximizes your energy savings. We then blow insulation to the specified depth, checking coverage throughout with depth markers. The entire process takes 3-5 hours for a standard OKC home. We clean up completely, leaving your home exactly as we found it — except significantly better insulated.
Blown-in insulation in the Oklahoma City area costs between $1.00 and $2.50 per square foot, depending on the material and application. A standard 1,200 square foot attic typically runs $1,400 to $2,400 to bring up to R-49. We provide free, no-obligation estimates with exact pricing for your home.
Both are excellent choices. We generally recommend cellulose for its superior density, air resistance, and built-in pest deterrent. However, fiberglass is the better choice if your attic has moisture concerns, since fiberglass does not absorb water. During your free estimate, we will inspect your attic and recommend the material that best fits your specific conditions.
Yes, but we account for this. Cellulose settles about 15-20% and fiberglass settles about 5-10% within the first year. We install to a greater initial depth so your insulation still meets the target R-value after settling is complete. After the first year, the insulation stabilizes and maintains its depth for decades.
Most attic blown-in insulation projects in the Oklahoma City area are completed in 3-5 hours. Wall insulation projects may take a full day depending on the number of wall cavities. Either way, you will start feeling improved comfort the same day the work is done.
