Fast, Reliable Spray Foam Insulation Across Burbank
Spray foam insulation in Burbank typically runs $2.80-$6.50 per board foot depending on open-cell or closed-cell product, with most whole-attic jobs falling between $3,200 and $7,800. Our crews are on Burbank streets five days a week, and we can usually inspect a Magnolia Park or Rancho corridor home within 24 hours of your call.
We know Burbank’s housing stock because we work in it constantly. The 1940s-1960s bungalows and ranches that dominate this city were built when California code required little to no wall insulation, and many still carry original fiberglass batts degraded far below current Title 24 standards. That gap between what your home has and what the San Fernando Valley’s thermal bowl demands is where we focus.

Our Spray Foam Insulation Services in Burbank
Closed-Cell Spray Foam
Closed-cell spray foam delivers R-6.5 per inch and forms a vapor barrier, making it the right choice for Burbank roof decks that face the Verdugo foothills and absorb that trapped thermal-bowl heat. We size the application carefully - undersized or poorly vented closed-cell on a roof deck can trap heat at the sheathing instead of blocking it. A typical closed-cell roof-deck application in Burbank runs $4.20-$6.50 per board foot, with most jobs between $4,800 and $8,200 depending on attic square footage.
Open-Cell Spray Foam
Open-cell runs R-3.6 per inch, breathes better than closed-cell, and costs less - typically $2.80-$4.00 per board foot in the Burbank market. We use it in attic assemblies and wall cavities where moisture management matters more than vapor blocking. On that 1947 ranch off North Hollywood Way in Magnolia Park, our tech opened the stucco wall cavity and found it completely empty, with original settled fiberglass batts in the attic degraded well below Title 24 minimums. We ran open-cell spray foam into the framed rim joist and attic assembly, then closed-cell along the roof deck to cut the 150°F-plus attic temps that were radiating straight into the living space. The homeowner reported the back bedrooms finally holding temperature through the August peak.
Rim Joist Spray Foam
The rim joist - the perimeter framing where your foundation meets the first floor - is often the leakiest part of a Burbank ranch’s envelope. In 1960s Rancho corridor homes with raised perimeter foundations, unsealed rim joists pull conditioned air straight into the crawl space year-round. We seal these with closed-cell spray foam after blower-door testing pinpoints the exact leakage path. Most Burbank rim joist jobs run $1,800-$3,400.
Garage Ceiling Spray Foam
Burbank’s attached garages, especially in postwar tracts with bedrooms above, create a direct thermal bridge when the ceiling is uninsulated. We spray open-cell or closed-cell foam against the garage ceiling to separate that unconditioned space from living areas above. Typical garage ceiling work in Burbank: $2,400-$4,600.
Spray Foam Roof Deck
This is where spray foam pays off most dramatically in Burbank. Applying foam directly to the underside of the roof deck turns your attic from a 150°F convection oven into a semi-conditioned space, dropping radiant heat transfer through the ceiling by 40-60%. We use closed-cell for this application, sized to R-30 minimum per current Title 24. Cost typically falls between $5,200 and $9,800 for an average Burbank attic.

AfterTrusted Brands We Service in Burbank
We source spray foam materials from Icynene, Knauf, and CertainTeed among others, with no proprietary lock-in that limits your options. For Burbank customers, this means we can match the product to the building - closed-cell Icynene MD-R-200 for roof decks that need vapor control, Knauf open-cell for attic assemblies where breathability matters, CertainTeed closed-cell for rim joists in high-moisture crawl spaces. We stock common formulations locally, so material delays don’t hold up your job. Every product carries manufacturer warranty, and our 365-Day Done Right Promise sits on top of that.
Common Spray Foam Insulation Problems We See in Burbank Homes
- Closed-cell sprayed over original settled batts in 1950s attics. This traps moisture against degraded fiberglass instead of replacing it. The assembly looks upgraded, but thermal performance stays poor and you risk mold at the sheathing. We remove old material before spraying - always.
- Off-gassing and adhesion failures on dusty, decades-old stucco. Burbank’s postwar block construction often has wall cavities coated with 70 years of dust and oxidation. Without proper surface prep - HEPA vacuuming, primer where needed - spray foam delaminates and releases odor for weeks.
- Undersized roof-deck foam in Verdugo-facing homes. The thermal-bowl effect pushes attic loads higher here than in mid-valley LA. R-19 on a roof deck in Burbank performs like R-13 in a cooler climate. We size to actual measured load, not generic charts.
- Empty wall cavities in Magnolia Park and Rancho corridor bungalows. Standard California practice for the era. Dense-pack blown-in cellulose or fiberglass is often the practical upgrade path, but where access allows, spray foam through small stucco holes delivers better air sealing. We assess each wall assembly individually.
Pricing for Spray Foam Insulation in Burbank, CA
| Application | Price per Board Foot | Typical Job Range |
|---|---|---|
| Open-cell spray foam (attic, walls) | $2.80-$4.00 | $3,200-$5,800 |
| Closed-cell spray foam (roof deck, rim joist) | $4.20-$6.50 | $4,800-$9,800 |
| Rim joist only | $4.20-$6.50 | $1,800-$3,400 |
| Garage ceiling | $2.80-$5.50 | $2,400-$4,600 |
What moves you within these ranges: total board feet required, access difficulty (steep roof deck vs. walkable attic), whether old insulation needs removal first, and whether air sealing of top plates, can lights, and penetrations is needed before foam goes in. At Envelope, air sealing is never an upsell - it’s prerequisite work completed before any insulation is added.

FAQs - Spray Foam Insulation in Burbank
Your walls are likely empty. California code in the 1940s-1960s did not require wall-cavity insulation, and your attic probably holds original fiberglass batts degraded to R-11 or lower. Newer Burbank construction meets Title 24 minimums of R-30+ in attics and insulated walls. We verify with thermal imaging and blower-door testing, then specify exactly where the heat is entering. Call (747) 294-2764 for a free estimate with written pricing.
Yes, in many cases. Burbank’s Magnolia Park and Rancho corridor postwar bungalows were built stucco-over-wood-frame with wall cavities California code left empty, so spray foam crews here routinely work through small stucco access holes rather than from interior drywall - a technique driven by the city’s legacy plaster-and-stucco construction rather than by weather. We drill, foam, and patch to match existing texture. The interior drywall stays intact. Cost runs higher than open-attic work due to labor, but far below gut renovation.
Yes, if sized and vented correctly. Burbank’s position against the Verdugo Mountains traps hot air and suppresses coastal breezes, pushing attic temperatures above 150°F. Closed-cell spray foam at R-30+ on the roof deck blocks that radiant load from entering conditioned space. The key is proper thickness and, where the assembly allows, ventilation strategy - undersized or unvented closed-cell can trap heat at the sheathing. We measure before specifying. Most Burbank roof-deck jobs pay back in 4-7 years through cooling-cost reduction.
You waste money and potentially create a moisture problem. Closed-cell sprayed over the original settled batts in a 1950s Burbank attic traps moisture against degraded fiberglass instead of replacing it, so the assembly looks upgraded but thermal performance stays poor. The old material compresses, creates voids, and can harbor mold against the roof deck. Our protocol: remove and dispose of old insulation, HEPA clean the deck, air seal all penetrations, then spray. The blower-door test confirms the improvement.
Usually, yes. 1960s Rancho corridor ranches with raised perimeter foundations typically have unsealed rim joists pulling conditioned air into the crawl space. Closed-cell spray foam at the rim joist stops that leakage path with minimal material - typically $1,800-$3,400 - and delivers outsized comfort improvement per dollar spent. We always blower-door before and after so you see the exact CFM50 reduction. Written scope, written price, written warranty before work starts.
