What the Blown In Blanket System Actually Is
The Blown In Blanket System — sometimes called BIBS — is a hybrid insulation method that combines the coverage consistency of blown-in loose fill with the containment structure of a fabric net. The netting is installed across open wall cavities or attic framing, and the insulation is blown in behind it under pressure, filling the entire cavity wall-to-wall, corner-to-corner, with no voids.
Standard batt insulation leaves gaps. Around outlets, at corners, behind pipes, anywhere the framing isn't perfectly uniform. Those gaps are air pathways. And air pathways are where thermal performance goes to die.
Blown In insulation installed via the blanket system eliminates that failure mode. The material conforms to the space as it fills — no folding, no compressing, no approximations. The result is a complete, consistent thermal layer that performs at the rated R-value because coverage is actually complete.
Our Blown In Insulation Services
Blown In Attic Insulation
The attic floor is the highest-impact location in most residential structures, and blown in attic insulation is the most efficient way to achieve consistent coverage across it. Loose-fill material distributed under pressure fills around obstructions — HVAC equipment, plumbing chases, irregular joist spacing — in a way that hand-fitted batts simply can't replicate.
We assess your current attic coverage during the estimate, identify gaps and compressed sections, and determine the additional depth needed to bring the assembly up to the R-value recommended for your climate zone. For most of Middle Tennessee, that target runs R-38 to R-60 at the attic floor.
Blown In Fiberglass Insulation
Blown in fiberglass insulation delivers the thermal performance of fiberglass in a loose-fill format — ideal for attics, wall cavities via the BIBS method, and retrofit applications where access limits what can be installed by hand.
Fiberglass loose-fill doesn't settle significantly over time, maintains its R-value across a wide temperature range, and is non-combustible. For large attic floors and open-frame wall applications in new construction, it's a highly efficient choice.
Blown In Cellulose Insulation
Blown in cellulose insulation is a dense-pack alternative made primarily from recycled paper fiber treated for fire resistance. It's heavier than fiberglass, which gives it better air resistance in wall cavity applications — relevant for older homes where air sealing is a particular concern.
Dense-pack cellulose can also be installed in existing closed walls through small access holes, making it an option for retrofit projects where opening walls isn't practical. The material settles slightly over time, which is factored into the installed depth during application.
Wall Cavity Applications — The BIBS Method
The Blown In Blanket System was developed specifically for wall cavities. A fabric net is stretched across the open framing, and the insulation is injected behind it through small ports until the cavity is completely full. No voids. No settling gaps at the top of the cavity. No compressed corners.
For builders and
blow in insulation contractors doing new construction or major renovations, BIBS is the specification that closes the gap between rated and actual R-value performance. Prince Insulation has been installing it long enough to know where the typical failure points are — and how to avoid them.
Why This Method Outperforms Standard Batts
Most people default to batt insulation because it's familiar. That familiarity is reasonable — batts have been the standard for decades and perform adequately in straightforward applications. But adequately isn't the same as optimally.
This is usually where people run into problems: a home that feels drafty despite having insulation, utility bills that don't respond to upgrades elsewhere, moisture collecting in wall cavities. The insulation is there. The installation just left pathways that negated the R-value on the label.
The Blown In Blanket System addresses this at the source. The netting keeps the material in place during and after installation. The pressure-fill process reaches every corner of the cavity. There's no version of this installation where a joist bay gets half-covered because the batt was cut short.
For new construction, it integrates cleanly into the build schedule. For renovation projects with open walls, it's a direct upgrade over what was there before.
Looking for Blown In Insulation Near Me?
Searching Blown In insulation near me and not sure how to evaluate the options? A few things worth confirming before you commit to any contractor:
Do they use proper netting in wall cavity applications, or are they just blowing loose-fill into open bays and hoping for the best? Do they own their blowing equipment, or are they renting job to job? Is the crew in-house, or are they calling subcontractors whose work they can't vouch for?
Blow in insulation companies that operate at volume in a specific region understand local building stock, climate zone requirements, and the details that actually affect long-term performance. Prince Insulation has been answering the
Blown In insulation near me search in this region since before most people were making it.
What Sets Prince Insulation Apart
Decades in the trade. We added blown-in services to our offering as the product and equipment evolved — and we've invested in the equipment capacity to handle any project size without cutting corners on coverage depth or fill pressure.
In-house crew. Every blow in insulation installer on a Prince Insulation job is a full-time employee. No day labor, no unfamiliar subcontractors, no one learning the process at your expense.
Proper equipment, properly maintained. Blowing machines that aren't calibrated or maintained produce inconsistent fill density — material that looks complete but has air pockets throughout. Our equipment is maintained to spec. The fill is consistent. The performance is what it's supposed to be.

Frequently Asked Questions
How does the Blown In Blanket System differ from standard blown-in insulation?
Standard blown-in insulation is distributed as loose fill into open attic spaces. The Blown In Blanket System adds a fabric netting stretched across open wall cavities before the material is injected — containing the insulation under pressure and ensuring complete cavity fill with no voids. It's the difference between loose coverage and a fully packed, dimensionally stable installation.
Is blown in attic insulation better than batt for existing homes?
In most retrofit attic applications, yes. Blown in attic insulation reaches around existing obstructions — HVAC equipment, wiring, plumbing — without requiring hand-fitting around each one. It achieves more consistent coverage, particularly in attics with irregular joist spacing or significant existing infrastructure. For new construction with clear, accessible attic floors, batts remain a viable option.
What's the difference between blown in fiberglass and blown in cellulose?
Blown in fiberglass insulation is lighter, non-combustible, and maintains its R-value well over time with minimal settling. Blown in cellulose insulation is denser, provides better air resistance in wall cavity applications, and can be installed in closed walls via dense-pack methods. The right choice depends on the application, the existing structure, and the performance goals we're working toward.
How long does a blown-in installation take?
Most residential projects are completed in a single day. Large commercial projects or homes with significant existing insulation that needs to be addressed first may extend the scope. Prince Insulation provides a clear timeline during the estimate — no vague commitments. Most jobs fall apart because of timing, not the work itself, which is why we're specific about scheduling from the start.
How do I know what R-value I need for my project?
R-value requirements depend on your climate zone, the building assembly, and whether the project is new construction or a retrofit. For most Blown In Blanket System in Decherd and Tullahoma, TN projects, attic targets run R-38 to R-60 and wall targets vary based on framing depth and code requirements. Our blow in insulation contractor team assesses your specific project during the free estimate and recommends specifications that meet or exceed current energy code.
