Net and blow insulation is a method where insulation netting is stapled across open cavities, then blown fiberglass or cellulose fills behind it using professional equipment. Qute Insulation installs net-and-blow insulation throughout Chicagoland and Northwest Indiana for both new construction and retrofit projects.
Net & blow insulation uses fabric or mesh netting stapled across wall, ceiling, or floor cavities, then blown fiberglass or cellulose is driven in behind it with a professional blow-in machine. Qute Insulation installs net-and-blow insulation throughout Chicagoland and NW Indiana for complete, gap-free thermal coverage.
It outperforms traditional batt insulation by filling every cavity, corner, at uniform density with zero voids, no compression, and no gaps around wiring or pipes. For Chicago’s brutal winters and NW Indiana’s freeze-thaw cycles, that uniform coverage directly reduces heat loss through walls and attics.
Insulation netting holds blown material uniformly across every wall cavity, joist bay, and irregular framing space with no gaps or compression. Fiberglass batts routinely leave air pockets around wiring and pipes, a common problem in older Chicago bungalows and two-flats that net and blow eliminates.
Blown fiberglass achieves R-2.2 to R-2.7 per inch; blown cellulose reaches R-3.2 to R-3.8 per inch. IECC Climate Zone 5 requires R-38 to R-49 for Chicagoland attics and R-13 to R-15 for walls. Net and blow achieves the target R-value more reliably than batts due to uniform cavity density.
Blown cellulose's dense, irregular fiber mass absorbs sound waves better than fiberglass batts at equivalent thickness. For urban Chicago homes near transit lines and airports, and NW Indiana homes in mixed-use areas, net and blow cellulose wall insulation delivers measurable acoustic improvement alongside thermal performance.
Properly installed net and blow insulation reduces ComEd and Nicor Gas costs by stopping heat loss through Chicagoland walls and attics. DOE and ENERGY STAR identify wall and attic insulation as top priorities for Climate Zone 5. Documented upgrades support stronger appraisals in the NW Indiana and Chicagoland markets.

Every Qute Insulation project follows a consistent five-step process from assessment to cleanup.
We inspect existing insulation depth, air leakage points, moisture issues, framing condition, and cavity dimensions to determine whether blown fiberglass or cellulose suits the application.
We recommend blown fiberglass or cellulose based on application, homeowner goals, and IECC Climate Zone 5 requirements, including bag count, depth, and coverage chart.
We staple blow-in insulation netting across open wall, ceiling, or floor cavities, protect finished surfaces, and set up a professional blow-in machine before application.
We blow fiberglass or cellulose behind the netting to target depth using a professional-grade blow-in machine, verifying uniform density against the coverage chart.
We verify insulation depth and R-value, inspect netting integrity, remove all masking and protective covers, complete full cleanup, and walk you through the completed work.
Blown fiberglass net and blow wall insulation costs $1.40–$3.00 per square foot installed; blown cellulose net and blow runs $1.40–$3.40 per square foot; attic blow-in costs $1.00–$2.40 per square foot across the Chicago and NW Indiana market. Cost depends on material, cavity size, depth, and access. Contact Qute Insulation for a free written estimate.
For new construction walls and retrofit insulation in older Chicagoland homes, net and blow insulation outperforms fiberglass batts because it fills every corner and cavity with no compression or voids. Batts carry a lower upfront cost but leave gaps around wiring and irregular framing that reduce real-world R-value performance significantly.
For Chicagoland wall cavities, blown cellulose provides better air infiltration resistance; blown fiberglass is lighter and handles humid attic conditions well. Cellulose, including Greenfiber products delivers R-3.5 per inch and contains 75–85% recycled content. Fiberglass, including Atticat blown-in, costs slightly less and settles less over time.
Qute Insulation's certified installers bring hands-on experience with Chicagoland home types, new construction open stud walls, brick bungalow retrofits, and NW Indiana ranch homes. Our team understands netting installation, coverage chart calculations, and irregular framing patterns common in older Chicago construction. Licensed and insured on every project.
Our professional blow-in machine achieves correct material density, uniform depth, and target R-value that rental units consistently fail to deliver. Rental machines distribute material unevenly settled R-value that falls short, and bags are wasted. We use professional-grade equipment and quality blow-in insulation netting materials on every project.
Qute Insulation provides written quotes specifying material type, bag count, target depth, and square footage before work begins. No cost surprises after the machine starts. Pricing is consistent across all service areas from Gary, IN to Flossmoor, IL. Free estimates available with no obligation.
Our team knows IECC Climate Zone 5 R-value requirements, Illinois and Indiana energy codes, and insulation vulnerabilities in Crown Point, Homewood, Joliet, Monee, and Park Forest homes. Lake-effect cold and freeze-thaw cycles demand the uniform, gap-free coverage that net and blow insulation delivers consistently.
Robert Williams, Homewood "Our walls were ice-cold all winter, and our Nicor Gas bill ran over $280 every January. After Qute Insulation installed net and blown insulation throughout our exterior walls, our heating bill dropped by $105 a month, and the cold spots are completely gone."

Blown fiberglass and cellulose are safe once settled. Installers wear respirator masks, safety glasses, and gloves during the entire blowing process. Family and pets should stay clear during installation. Modern blown cellulose is borate-treated, fire-resistant, non-toxic, and contains no asbestos. Both materials are safe for occupants immediately after installation is complete.
Net and blow insulation lasts 20–30 years with minimal maintenance when professionally installed. Cellulose settles 15–20%, our team accounts for this in initial depth targets, so R-value holds long-term. Check Chicagoland attics every ten years for moisture damage, pest intrusion, or compression from foot traffic in attic areas.
Net and blow insulation uses netting or mesh fabric stapled across open cavities, then blown fiberglass or cellulose fills behind it using a professional blow-in machine. The netting holds material at uniform density, eliminating the gaps and voids that batt insulation consistently leaves behind.
For walls, blow-in insulation netting is stapled across open stud cavities before blowing, ideal for new construction. For retrofits, small holes are drilled, and insulation is blown in. For attics, netting at eaves and irregular areas contains blown material at the correct depth and density.
Blown fiberglass or cellulose net and blow wall insulation costs $1.40–$3.40 per square foot installed; attic blow-in runs $1.00–$2.40 per square foot in the Chicago and NW Indiana market. Cost depends on material, cavity size, depth, and access. Qute Insulation provides free written estimates.
Blown fiberglass achieves R-2.2 to R-2.7 per inch; blown cellulose achieves R-3.2 to R-3.8 per inch. For IECC Climate Zone 5, attics require R-38 to R-49, and walls require R-13 to R-15. Net and blow achieves the target R-value more reliably than batts due to uniform cavity fill.
No modern blown cellulose or blown fiberglass contains asbestos. Old loose-fill material in pre-1980 Chicagoland homes may be vermiculite or other asbestos-containing material that is not cellulose. If uncertain about existing attic material, have it professionally tested before disturbing it.
Blown cellulose is borate-treated and meets Class I fire rating standards. It is not flammable despite being paper-based. Blown fiberglass is non-combustible. Both materials meet the Illinois and Indiana residential building code fire resistance requirements for wall and attic insulation applications.
Neither blown cellulose nor blown fiberglass works for net and blow insulation. Cellulose provides a slightly higher R-value per inch and better air infiltration resistance. Fiberglass is lighter and handles humidity well. Qute Insulation recommends the right material for your specific application after a free in-home assessment.
The three main types are blown-in loose-fill insulation, batt insulation, and spray foam insulation. Net and blow is a professional installation method for loose-fill blown insulation that delivers more consistent R-value than standard batt installation across Chicagoland’s extreme seasonal climate conditions.
Blown cellulose is brown or gray with visible paper fiber texture; blown fiberglass is pink, yellow, or white with a light cottony appearance; vermiculite is silver-gray and pebble-like. If you find gray pebble-like material in a pre-1980 Chicagoland home, do not disturb it, contact a professional for asbestos testing.
Yes net and blow insulation fills every stud cavity at uniform density with no gaps around wiring or pipes. It consistently achieves IECC Climate Zone 5 R-value targets required by Indiana energy codes a performance that fiberglass batt insulation frequently falls short of in new construction.
