Insulation Company in Century City, CA
Blown in insulation in Century City means something different than it does almost anywhere else in Los Angeles. Here, the work is acoustical and condensation-control insulation inside tower-and-podium buildings, not attic fills over single-family homes. Airtight Insulation Co installs blown in cellulose and fiberglass in the 90067 high-rises and mid-rises, where tenant-improvement cycles and mechanical-room retrofits drive most of the demand. Call (833) 390-7079 for a straight answer on your building.
Why Century City Homes Are Different
Century City sits on the former 20th Century Fox backlot, and the build environment still reflects that origin: a dense campus of steel-frame high-rises with glass curtain walls, mid-century mid-rises along Avenue of the Stars and Constellation Boulevard, and luxury condo towers wrapping the Westfield mall. You will not find pitched attics or gable vents here. The insulation scope concentrates on interior partitions, mechanical rooms, duct risers, and acoustical treatments between suites.
The climate shapes the work too. Mild marine air keeps heating and cooling loads modest most of the year, which means thermal R-value is rarely the deciding factor. The real problems are solar gain through large west- and south-facing curtain walls during Santa Ana events, condensation forming on chilled-water piping and duct systems, and tenant-to-tenant noise transfer through demising walls. A blown in material that handles density and cavity coverage well, like cellulose, often fits the acoustical and condensation-control brief better than a batt that leaves seams.
Construction logistics also set Century City apart. Most buildings manage freight-elevator scheduling, required hours of work, and insurance certificate rules through the property management office. Any insulation contractor working in 90067 has to plan around building-managed access windows and hoist time. Airtight Insulation Co has served Century City since 2011, and we know how to coordinate with the front desks and building engineers so the job does not stall in the loading dock.
Our Main Century City Services
Two services account for most of what Century City property managers and condo boards call Airtight Insulation Co about. Each has its own dedicated page for Century City, linked below.
Attic Insulation in Century City
Attic work in Century City is not the ranch-house job most people picture. Here it means insulating the interstitial spaces above top-floor condo units, the drywall ceilings under mechanical penthouses, and any small service attic above a mid-rise elevator core. The goal is usually acoustical separation from rooftop equipment and protection for the ceiling drywall below a hot penthouse slab. Condensation on chilled-water lines running through these spaces is a recurring problem, and the right insulation and vapor control stops the ceiling stains that follow. Read the full breakdown on our Attic Insulation in Century City page.
Spray Foam Insulation in Century City
Curtain-wall buildings in Century City leak air at the floor-slab edge, the spandrel panels, and where duct risers punch through shafts. Closed-cell spray foam is the only material that seals those gaps and insulates in one pass, which is why TI contractors bring us in when a suite on Avenue of the Stars keeps pulling in dry, hot air during Santa Ana days. We run Icynene and Demilec open- and closed-cell products, so the spec can match the application rather than forcing one formula on every cavity. Details are on our Spray Foam Insulation in Century City page.

Blown In Insulation in Century City
Blown in insulation in Century City primarily solves two problems: tenant-to-tenant sound transfer through interior partitions and condensation control around chilled-water piping and duct risers in mechanical rooms. The tower-and-podium construction here means open cavities in steel studs and mechanical chases are everywhere, and blown in cellulose or fiberglass can fill those irregular voids without gutting the wall. In the 90067 stock, that matters because a full stud-out demolition is expensive and disruptive to occupied floors. For a deeper look at materials and method, see our Blown In Insulation hub.
Cellulose Insulation
Signs you need it
You hear conversations and chair movement from the suite next door through a shared wall, or you feel the wall cavity is hollow when a contractor cuts an outlet opening.
What it costs in Century City
Blown in cellulose in Century City typically runs $1.10 – $2.25 per square foot of installed area, depending on cavity depth and access.
How we do it
We drill small access holes in the drywall from one side, dense-pack the cavity with GreenFiber cellulose to fill every irregular stud bay, and patch the holes clean for paint.
Blown In Attic Insulation
Signs you need it
The top-floor unit directly under a mechanical penthouse stays warm in summer and the ceiling shows faint water staining near chilled-water pipe penetrations.
What it costs in Century City
Blown in attic insulation above these ceiling plenums typically lands between $1,200 and $3,400 per project, driven by hoist scheduling and containment requirements.
How we do it
We access the service attic opening, verify the pipe wraps and duct insulation first, then blow loose fill to a consistent depth across the deck while keeping exhaust airflow clear.
Blown In Fiberglass Insulation
Signs you need it
A mechanical chase between floors is open and transferring fan noise or cold air from the penthouse into occupied corridors below.
What it costs in Century City
Blown in fiberglass in 90067 mechanical chases and partition cavities typically runs $1.30 – $2.60 per square foot, including dense-pack or loose-fill application.
How we do it
We blow loose-fill fiberglass from Owens Corning or Johns Manville into the open cavity, using netting or membrane where the space is vertical, and confirm coverage density before closing.
Loose Fill Insulation
Signs you need it
An existing condo ceiling cavity has settled or disturbed insulation from past plumbing or electrical work, leaving thin spots that let sound and heat through.
What it costs in Century City
Loose fill top-up work in Century City generally runs $0.90 – $1.80 per square foot, assuming the cavity is already framed and accessible from above or through access panels.
How we do it
We blow loose fill to the specified depth across the entire floor deck, working around conduit and sprinkler lines, and level the coverage with a final pass.

Will blown in insulation reduce sound between Century City condo units?
Dense-packed cellulose in shared walls measurably cuts mid- and high-frequency voice noise and impact sound from adjacent suites. It is the most reliable upgrade short of rebuilding the wall assembly. Call (833) 390-7079 for a cavity-by-cavity assessment of your floor plan.
Can you work within Century City building hours and freight-elevator rules?
Yes. We schedule around building-managed construction windows and freight elevator reservations for 90067 projects. Our crews run dust-containment and hoist-safe material loading as standard practice on occupied commercial and condo floors.

What Century City Customers Say
"Spray foam in the rim joists in the basement. The cold floors above them are gone."
— Steve Ziegler"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
— Claudia Morales"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
— Simone Grant
