Reflectix Insulation in Los Angeles, CA | Cool House Insulation
We provide independent Reflectix insulation service across Los Angeles, from South LA bungalows to Wilshire corridor duplexes and Koreatown Reflectix service. The difference here is heat, not cold. Los Angeles attics routinely hit 150°F in summer, and that’s where Reflectix either performs beautifully or fails fast depending on how it was installed. We’re the crew that fixes what the last guy got wrong. Call (855) 341-7810 for a straight answer about your attic.
We work with the full Reflectix sales & service line: Double Reflective rolls, Reflective Foil, R-21 Attic Wall Radiant Barrier, and duct wrap. Noel Carrasco started this company because he kept seeing attics where the right product was installed the wrong way. That’s a Los Angeles problem more than anywhere else, and we’ll get into why below.
Why Los Angeles Residents Choose Us for Reflectix Service
We’ve pulled Reflectix out of more attics than most crews have ever installed. That matters because knowing how it fails tells you how to install it right. The foil-facing radiant barrier concept is simple. Making it survive a South LA attic through three Augusts is not.
Noel grew up in La Palma and has been working attics across the Los Angeles basin for well over a decade. He learned the trade through Cypress College’s construction technology program and spent years fixing the mistakes other installers made. When he says a radiant barrier needs ventilation space to work, he’s not quoting a brochure. He’s describing what he saw last week in a 1928 bungalow off South Central Avenue.
We are an independent contractor. We are not manufacturer-affiliated or authorized by Reflectix. That independence means we recommend what actually works for your house, not whatever we happen to stock.
Common Reflectix Insulation Problems We Solve in Los Angeles
- Foil delamination from extreme attic heat: In unvented South LA and Wilshire corridor attics, summer deck temperatures routinely exceed 150°F. That heat breaks down the adhesive bond between the foil facing and the bubble core. You end up with wrinkled, separated foil that reflects almost nothing. We see this on maybe one in three older Reflectix installs in 90005 through 90008.
- Ember intrusion at roof deck penetrations: Santa Ana winds push embers into attic spaces through gable vents, ridge gaps, and any penetration that isn’t sealed. Reflectix stapled loosely over rafters with gaps at the edges becomes a path for embers to reach wood framing. In older stucco-over-wood-frame bungalows, that’s a fire problem, not just an efficiency problem.
- Condensation and trapped moisture in unvented attics: Los Angeles has plenty of older homes with no vapor control at all. When Reflectix is installed tight to the roof deck without ventilation space, moisture gets trapped between the foil and the sheathing. You get corrosion, mold on the deck, and a radiant barrier that’s quietly degrading from the back side.
- Abrasion and damage around knob-and-tube wiring: The 1920s through 1950s housing stock across 90001 through 90010 still has knob-and-tube in places. Stapling foil over that wiring creates abrasion points and a real electrical hazard. We work around original wiring correctly, with clearance and proper fastening, before any R-value conversation happens.
- Generic foil replacements that fail faster: After a bad install or delamination, some homeowners patch with off-brand reflective foil from a big box store. Knockoff foils have lower emissivity and thinner facing. In Los Angeles heat, they fail in two summers instead of ten. We replace failed sections with genuine Reflectix material, not a cheaper substitute.
Reflectix Service in Los Angeles: What Local Conditions Mean for Your Equipment
Here’s what separates Los Angeles from every other city where Reflectix gets installed. In the 90001 through 90008 ZIPs, a radiant barrier has to do two jobs at once. It has to cut cooling load during long summers, and it has to be part of a fire-resistant assembly. South LA’s older wood-frame bungalows and duplexes sit close enough to wildfire-adjacent zones that ember behavior matters as much as R-value. Foil facing alone, stapled up without sealing and baffles, can wick flame along the deck. That’s not a coastal city problem. It’s not an inland valley problem in the same way. It’s a South LA, Central LA, and Reflectix in Echo Park reality.
What we do differently: every Reflectix install in these neighborhoods, including Reflectix repair in Silver Lake, gets a Class A fire-rated assembly approach, fire-rated tape at seams and penetrations, and ember-resistant detailing at any roof deck opening. The product is good. The installation is what determines whether it’s safe and whether it actually lowers your AC bill. If your energy bill is doing the talking, your insulation isn’t doing its job.
Reflectix Models & Products We Service in Los Angeles
We install and repair the full Reflectix line. That includes the Double Reflective Insulation Roll in both 16-inch and 24-inch widths, the Reflective Foil Insulation single-bubble 48-inch roll, the R-21 Attic Wall Radiant Barrier in perforated and solid variants, and the Duct Wrap and Pipe Wrap lines for HVAC runs and plumbing in unconditioned spaces.
For repairs, we keep genuine Reflectix rolls and approved accessories on hand: tape, fasteners, and baffles. That means faster turnaround for Los Angeles jobs. When an attic section fails, we don’t wait on a shipped roll. We pull from stock and get it fixed. For replacements, we use OEM material only.

FAQs – Reflectix Insulation in Los Angeles
Reflectix itself is a reflective insulation product, not a fire-rated assembly on its own. In Los Angeles, particularly in the 90001 – 90008 ZIPs, it must be installed as part of a Class A fire-rated assembly with proper sealing and ember-resistant detailing to meet wildfire code requirements. We handle that detailing on every job. Call (855) 341-7810 and we’ll assess your attic against current Los Angeles requirements.
Yes, but not by stapling foil over the wiring. Knob-and-tube requires clearance and careful fastening to avoid abrasion points and code violations. We’ve done this in pre-war bungalows across 90006 and 90007. The wiring gets worked around first, then the Reflectix goes in correctly. Call (855) 341-7810 for an inspection before you buy materials.
Unvented attics need ventilation space between the foil and the roof deck, typically 2-inch baffles, to prevent trapped moisture and condensation. Without that air gap, the assembly fails from the back side. We add appropriate baffles and sealing on every roof-deck install. That’s standard practice for us, not an add-on.
Reflectix radiant barrier isn’t primarily an R-value product. It works by reducing radiant heat gain, which in a Los Angeles attic can drop deck temperatures by 15 to 20°F and cut cooling load significantly. Combined with existing insulation, most homeowners notice the difference in their August energy bill within one season.
Yes. We remove delaminated, torn, or ember-damaged Reflectix and dispose of it before installing new material. If the delamination covers less than 20% of the surface, we may recommend repair instead of full replacement. We’ll show you the damage in the attic before we quote anything. Call (855) 341-7810 for a free estimate.
