We’ve worked in Burbank long enough to know the difference between a 1920s bungalow in the Rancho district and a 1960s tract house off Victory Boulevard. The housing stock here is old, the summers are brutal, and the airport noise is real. That combination means blown-in insulation work in Burbank isn’t a standard attic fill. It’s acoustic treatment, code compliance, and thermal performance wrapped into one job, often with original knob-and-tube wiring still live in the walls. Our Blown In Insulation team treats every Burbank house as the specific building it is, not a template.
Why Aspen Attic Insulation Is Burbank’s Preferred Blown In Insulation Company
Garrett Sloane built Aspen Attic Insulation on the Threshold Standard, which means every technician who knocks on your door in Burbank is background-checked, identity-verified, and sent to you by name and photo before the visit. If anyone else shows up, the visit is free and we make it right. That matters here. Burbank homeowners tell us they’re often home during the day, working remotely or caring for children, and opening the door to an unannounced stranger isn’t something they’ll do.
We answer the phone live, 24/7. No voicemail loops. When you call (864) 428-1615, a real person schedules your Burbank appointment and emails you your technician’s name, photo, and ID badge number. The price we put in writing before any work starts is the price you pay. Every job carries our 365-Day Done Right Promise: if the repair or installation fails within a year, we come back free and fix it.
Our crews know Burbank’s specific conditions. The west-facing attics that hit 105°F in July. The Magnolia Park bungalows with 1940s cellulose settled to half its original depth. The Title 24 inspections that fail unsealed top plates. We don’t learn this on your job. We arrive already informed.
Blown In Fiberglass Insulation in Burbank
Blown In Fiberglass Insulation in Burbank is the white, fluffy loose-fill material you see in most attics, made from spun glass fibers and installed with a blower hose to fill joist cavities and cover irregular spaces. A typical Burbank attic retrofit with blown-in fiberglass runs $2.20 – $3.80 per square foot, or about $2,800 – $5,200 for a 1,200-square-foot attic including basic air-sealing. We use Owens Corning and Johns Manville fiberglass products matched to your specific attic conditions, not whatever’s on the truck.
Burbank homeowners need blown-in fiberglass when their attic has thin, patchy, or settled existing insulation, when they’re adding HVAC ductwork that disturbs what was there, or when a home energy audit shows R-values below Title 24 compliance. The hot San Fernando Valley sun makes this a priority, not a someday project. An attic that reads 140°F in August is cooking your ducts and forcing your AC to run overtime.
When Fiberglass Makes Sense Over Cellulose
Fiberglass doesn’t settle as much as cellulose, and it resists moisture better in Burbank’s rare but real winter rains. If your attic has active roof leaks or poor ventilation we haven’t fixed yet, fiberglass is the safer choice. It also doesn’t require the same fire-retardant treatments cellulose does, which matters in some Burbank historic districts with specific material restrictions.
Air-Sealing Before the Blow
We never blow fiberglass over an unsealed attic. Open top plates, recessed light cans, and chimney chases let conditioned air escape and invite dust from Burbank’s dry summer winds. Our techs seal first with caulk and foam, then blow to the specified depth. The insulation performs. The house passes inspection. You don’t get a callback.
Loose Fill Insulation in Burbank
Loose Fill Insulation in Burbank refers to any fiber-based material, cellulose or fiberglass, blown dry into attic cavities or dense-packed into closed wall assemblies. A standard Burbank attic loose-fill job runs $1.80 – $3.20 per square foot for cellulose, or $2,200 – $4,500 total for a typical 1,000 – 1,400 square foot attic with prep work included. Dense-packing walls for sound control, common under Hollywood Burbank Airport flight paths, adds $2.50 – $4.50 per square foot depending on cavity depth and access.
We use loose fill in Burbank for three specific situations: attics with settled or disturbed old insulation that needs complete replacement, wall cavities where aircraft noise is the primary complaint, and homes where knob-and-tube wiring requires a material that can be carefully worked around without compression or contact. Our GreenFiber and Johns Manville cellulose products are treated with borate fire retardant and resist pests, which matters in Burbank’s older wood-framed housing stock.
Dense-Pack for Airport Noise
Standard loose-fill in an open attic won’t stop aircraft noise. For that, we dense-pack wall cavities at 3.5 – 4.0 pounds per cubic foot, creating a solid mass that absorbs sound vibration. We often pair this with resilient channel or double drywall on the interior. It’s a specific acoustic specification we quote separately from thermal work, and it’s one of the most common requests we get in Burbank that we rarely see in Glendale or Pasadena.
Working Around Old Wiring
Burbank’s pre-war bungalows still carry active knob-and-tube in many attics. We photograph every run, maintain code-required clearances, and air-seal around porcelain knobs with fire-rated foam before any loose-fill goes down. This isn’t optional. Burbank inspectors flag contact between insulation and unapproved wiring, and we won’t put a homeowner in that position.
Trusted Brands We Service in Burbank
We stock materials from eight industry-leading brands, and we bring the right product for your specific Burbank home, not the one we have the most of. For blown-in work in this market, we most often specify Owens Corning fiberglass for attic retrofits, Johns Manville cellulose for dense-pack acoustic jobs, and Knauf fiberglass when moisture resistance is the priority. Rockwool mineral wool comes out for fire-blocking and high-heat applications near chimneys or furnace flues. Because we source from multiple suppliers, we don’t tell Burbank homeowners to wait three weeks for a special order. The material is on the truck or in our local warehouse, and the job moves on schedule.
Common Blown In Insulation Problems We See in Burbank Homes
- Settled 1940s cellulose in Rancho and Magnolia Park attics. Original cellulose compresses over 80 years and gets disturbed by every HVAC upgrade and rewiring job. What’s left is thin patches, low R-values, and exposed drywall. Blown-in alone won’t fix this. We remove or re-level the old material, air-seal, then install new loose-fill to full depth.
- Unsealed top plates leaking into wall cavities. Pre-war Burbank bungalows have open framing at the wall-to-attic junction. Blow fiberglass without sealing first, and it drifts into soffits, wastes material, and fails Title 24 compliance. We seal every plate with foam before the blower starts.
- Blown-in over knob-and-tube without proper clearances. This creates a coverage failure and a code hazard. Burbank inspectors will flag it, and more importantly, it’s not safe. We map the wiring, maintain separation, and document our work with photos.
- West- and south-facing attics without radiant barriers or ventilation. Burbank’s 100°F afternoons will overwhelm insulation alone. We assess attic ventilation and recommend radiant barrier foil or cool-roof prep when the thermal load demands it. Otherwise, the homeowner blames the insulation for what is really a ventilation problem.
Pricing for Blown In Insulation in Burbank, CA
Most Burbank homeowners want real numbers before they invite someone into their home. Here are the ranges we see on actual jobs in this market:
| Attic loose-fill cellulose (basic, no prep) | $1.80 – $2.80/sq ft |

FAQs About Blown In Insulation in Burbank
Standard attic loose-fill does very little for aircraft noise. For real sound reduction, we dense-pack wall cavities with cellulose at 3.5 – 4.0 pounds per cubic foot and often add resilient channel or double drywall. That’s the specification that drops decibels measurably. Call (864) 428-1615 for an acoustic assessment if flight-path noise is your main concern.
Yes, but only with specific precautions. We photograph all wiring, maintain code-required clearances, and air-seal around porcelain knobs with fire-rated foam before installing loose-fill. We never bury live knob-and-tube in contact with insulation. Burbank inspectors will flag that, and we won’t do it.
1940s cellulose settles naturally over 80-plus years, and every HVAC or electrical retrofit disturbs it further. What’s left is often half the original depth, with thin patches and exposed ceiling drywall. We remove or re-level the old material, seal air leaks, then blow new cellulose or fiberglass to full specified depth.
Yes. California’s Title 24 and the Burbank Green Building Code set minimum R-values and require verified air-sealing for all insulation retrofits. Unsealed top plates and leaking recessed cans will fail inspection regardless of how much insulation you install. We build every Burbank quote to pass Title 24 the first time.
It helps, but insulation alone isn’t enough on west- and south-facing attics that hit 140°F. We assess ventilation and often recommend radiant barrier foil or improved soffit and ridge venting alongside the blown-in work. Otherwise you’re fighting heat gain with insulation that was never designed to stop radiant transfer. Call (864) 428-1615 and we’ll evaluate your specific attic conditions.
