Why Airtight Insulation Co Is Burbank’s Preferred Spray Foam Insulation Company
Burbank keeps calling us back because we don’t treat a 1952 stucco ranch off North Keystone like a new build in the Hollywood Hills. Ruben Acosta has walked more shallow-rafter attics in 91501 and 91506 than most crews see in a decade, and he trains every installer on what that means: cut baffles before you spray, box the cans, respect the lot line. The work “let the job pick the product” matters here more than anywhere in the Valley, because Burbank’s housing stock is old, tight, and unforgiving. We bring Icynene and Demilec open- and closed-cell foam, not whatever is in the truck. Seal it, not just fill it, and the AC bill tells the difference by July.
Crawl Space Spray Foam Insulation in Burbank
Crawl Space Spray Foam Insulation in Burbank is a retrofit for the raised-foundation bungalows that dominate the flats below Glenoaks, where vented crawl spaces pull up cold air all winter and radiate heat into the subfloor through summer. We spray closed-cell foam against the rim joist and, when the homeowner wants a conditioned crawl, line the perimeter walls and seal the ground with a vapor barrier first. This blocks air movement and keeps pipe chases and floor framing from sweating during Burbank’s cool, dry winter nights.
Rim Joist Sealing
The rim joist is the biggest air leak in a raised Burbank floor. We spray it with closed-cell Demilec or Icynene from the inside of the crawl, sealing each bay against the band board. This stops stack effect and keeps dust and valley heat from entering under the floor.
Closed-Cell Perimeter Wall
For a fully conditioned crawl space, we spray closed-cell foam directly to the foundation walls and stem walls, then tie it to a sealed ground retarder. This works in the dense Burbank lots where outside access is tight, because the crew works from inside the crawl, not around the house.
Garage Spray Foam Insulation in Burbank
Garage Spray Foam Insulation in Burbank turns an unconditioned attached garage into a usable space without running ducts across the ceiling. Most older Burbank homes have a one-car or narrow two-car garage sharing a wall with the living space, and the uninsulated garage soaks up valley heat all afternoon. We spray closed-cell foam under the roof deck or on the shared wall and ceiling, sealing air and adding R-value in the same pass.
Shared Wall Air Sealing
When the garage wall backs onto a bedroom or kitchen, we spray that whole wall with closed-cell foam. It cuts noise from the alley and blocks the hot air mass that used to bleed through the drywall into the house every evening.
Attached Garage Ceiling
For garages under occupied rooms, we spray the ceiling cavity with open-cell foam to slow heat transfer and reduce sound. This is the retrofit that lets a Burbank homeowner actually use the garage as a workshop in August.
Trusted Brands We Service in Burbank
We stock and spray Icynene and Demilec open- and closed-cell foams, and that gives us the flexibility to match material to Burbank’s specific building stock instead of pushing one product. For fiberglass and mineral wool tie-ins around foam jobs, we carry Owens Corning, Johns Manville, Knauf, CertainTeed, and Rockwool, plus GreenFiber cellulose when a blown-in hybrid makes sense. Eight brands, one contractor. We keep foam stock staged locally for Burbank jobs, so turnaround doesn’t depend on a supply house run across the Valley.
Common Spray Foam Insulation Problems We See in Burbank Homes
- Closed-cell sprayed over unvented shallow rafter bays. The original 2×4 rafters in 1940s and ’50s Burbank bungalows have no vent channel. Foam sprayed tight against the roof deck traps moisture and cooks the sheathing. We cut baffles or furr the rafters deeper before any closed-cell goes in.
- Legacy knob-and-tube-era penetrations left unboxed. Older homes in the 91501 – 91506 flats were re-wired decades after the original top plates and can lights went in. If those penetrations aren’t sealed and boxed before foam, hot air bypasses the seal and recessed cans sit buried in foam, overheating.
- Compressor staging on a dense Burbank lot line. These houses sit tight to the property line. A hot day, a cramped side yard, and a rushed spray pass mean off-ratio foam that cures soft. We set the compressor against the house, not the neighbor’s fence, and take the extra time.
- Thin original batt insulation compressed under 70 years of service. We find 2-inch batts reduced to a quarter of their original R-value. Spray foam fixes the air leak that the batt never addressed, which is the real driver of comfort in Burbank’s summer heat.

FAQs About Spray Foam Insulation in Burbank
Yes, but we do it as a retrofit, not a new-build spray job. We cut baffles to maintain a vent channel, furr the rafters if needed for depth, and seal and box every penetration and can-light box before foam goes in. That’s the only correct way to foam a pre-1960 Burbank attic.
Yes. Closed-cell foam on the attic floor and top plates stops the air exchange that pulls 140°F attic air into the living space during the day and lets heat escape all winter night. In a Burbank bungalow with original single-pane windows and minimal wall insulation, air sealing the attic is the highest-leverage upgrade you can make. Call us at (833) 390-7079 for a heat-gain inspection.
Where a garage or crawl space is adjacent to conditioned space, sealing and insulating those boundaries counts toward California’s Title 24 envelope requirements, and Burbank’s permit office enforces it closely on retrofits. We write up every foam application so it lands within Title 24’s air sealing and insulation mandates, not against them.
We stage the compressor in the driveway or against the house wall, never on the neighbor’s side. Hoses run through a side gate or window, and the rig stays out of the street unless we have a parking permit. That tight-lot reality is why we plan Burbank jobs day-of, not day-before.
Air seal first, then decide on insulation. If the garage shares a wall or ceiling with living space and you feel the heat coming through, spray foam on that shared surface is the right fix. If the garage is detached and you just want it cooler for a workshop, sealing the door and vents plus an open-cell ceiling often does enough for less cost. We’ll tell you which fits after a fifteen-minute walkthrough.
