Reflectix Insulation in Hollywood, CA | Thermal Insulation Co
We provide independent Reflectix installation and correction across Hollywood, CA. Our work in Hollywood is shaped by the reality that most buildings here are 1920s-era apartments and bungalows with little or no original insulation, and foil products get spec’d fast and installed wrong faster. If you’re in the 90028 ZIP code and your Reflectix isn’t performing, or you’re considering it for an attic or wall cavity, call us at (855) 382-3451. We’ll tell you honestly whether foil is the right tool for your structure.
Why Hollywood Residents Choose Us for Reflectix Service
Ruben Castellano has spent the better part of two decades working insulation across the San Gabriel Valley and east Los Angeles corridor. He learned building science fundamentals at East Los Angeles College before he ever picked up a spray rig, and that grounding shows in how we approach Reflectix work, including Reflectix repair in Koreatown. We inspect the assembly first, not the product. That matters in Hollywood, where a foil roll bought at a box store gets stapled to rafters by someone who never learned that radiant barriers need an air gap to function.
We’re an independent contractor, not affiliated with or authorized by Reflectix. We stock Reflectix-brand foil where the spec genuinely calls for a radiant barrier, and we pair it with compatible foil tape and fasteners. But we’ll also tell you when foil is the wrong tool for a given cavity, because in Hollywood’s older building stock, that conversation happens more often than people expect. For broader material options, see our Reflectix sales & service page.
Common Reflectix Insulation Problems We Solve in Hollywood
- Foil stapled directly to roof rafters with no air gap. This is the classic Hollywood install error, and we see it constantly in quick retrofits on 1920s bungalow roof decks. Reflectix works as a radiant barrier only when there’s an air space facing the foil. Without it, the foil conducts heat into the attic instead of reflecting it, and the space gets hotter, not cooler.
- Reflectix laid flat over attic floor joists as a substitute for real insulation. In courtyard apartments around 90028, we regularly find foil taped to joists and called done. Radiant barrier handles radiant heat transfer. It does almost nothing for conduction, which is the bigger problem in a Hollywood attic baking under afternoon sun. The unit stays hot because the actual insulation was never installed.
- Perforated vs. non-perforated foil misapplied in wall or crawl assemblies. Non-perforated Reflectix is a vapor barrier. Put it in the wrong layer of a wall, and you create a double vapor barrier that traps moisture against lath-and-plaster or stucco-over-open-stud walls. We’ve peeled foil off Hollywood walls to find damp, crumbling plaster behind it.
- Staples and seams failing under attic heat cycling. Hollywood attics swing from cool mornings to 130 degrees plus by late afternoon. That expansion and contraction works staples loose, tears seams, and leaves foil sagging or falling. In older buildings, sagging foil sometimes ends up in contact with knob-and-tube wiring, which is a hazard we address immediately.
- Reflectix installed over existing insulation with no baffles. Foil pressed against batts or blown-in insulation loses its reflective capacity and can trap condensation at the contact point. We correct this by installing proper baffles and re-hanging the foil with the air gap it needs.
Reflectix Service in Hollywood: What Local Conditions Mean for Your Equipment
On Hollywood’s hillside and canyon edges, many 1920s bungalows have no wall sheathing at all. Just stucco nailed over open stud bays. That changes everything about how Reflectix can be installed. You can’t simply staple foil into a cavity and seal it, because the stucco itself is part of the air and moisture path. When we add foil or dense-pack insulation behind stucco like this, we have to account for how the wall breathes through the stucco, not around it. Get that wrong and you’re trapping moisture against a wall that was never designed to be sealed.
This is distinct from what you’d find in Studio City or Van Nuys, where post-war construction with sheathed walls behaves differently. In Hollywood, the wall assembly itself dictates the install method. We work with that reality rather than against it. For coverage across the broader area, see our Hollywood service area page.
Reflectix Models & Products We Service in Hollywood
We work with the standard Reflectix product lines you’ll find in Hollywood homes and apartments: the Double Reflective Insulation Roll in 16-inch and 24-inch widths, the Double Reflective Foil Insulation with adhesive for duct and radiant applications, the R-8 Reflective Foam Core rigid panels, and the perforated foil roll for attic roof-deck stapling. We keep compatible foil tape and fasteners on hand so turnaround is fast.
When the existing Reflectix product isn’t right for the cavity, we say so. In many Hollywood attics, the better fix is blown-in insulation or dense-pack wall insulation with perforated foil used only where it actually contributes. Our stance is simple: foil is a supplement to an insulated, air-sealed assembly, not a replacement for it.
Reflectix Service Pricing in Hollywood
Reflectix work in Hollywood varies based on what we find. A straightforward attic radiant barrier install over an existing roof deck in a 90028 bungalow runs a different range than correcting a failed install or adding dense-pack insulation behind a stucco wall. The biggest cost drivers are access, the condition of the existing assembly, and whether we’re starting fresh or undoing someone else’s work.
Every estimate starts with a free inspection. We look at the cavity, the roof deck, the existing insulation if any, and the wiring. Then we give you a straight answer with a line-item scope. If foil is the wrong call, we’ll tell you before you spend a dollar on material. Call (855) 382-3451 to schedule a free estimate.

FAQs – Reflectix Insulation in Hollywood
No. Reflectix is a radiant barrier, not insulation. It reflects radiant heat toward it, but a 1920s Hollywood attic with no insulation still gains heat through conduction and airflow. You need insulation first, air sealing second, and foil only as a supplement. Call (855) 382-3451 and we’ll inspect your attic before you buy anything.
Almost always because the foil was installed without an air gap or was laid flat over joists, which means it has little or no radiant barrier performance. A courtyard apartment owner near the Hollywood Blvd side of 90028, not far from where we also provide Reflectix service in Echo Park, had a previous handyman staple non-perforated Reflectix tight to the rafters. Top-unit tenants baked by 2 p.m. anyway. We pulled it down, added baffles and an air gap, blew in insulation, and re-hung perforated Reflectix properly. Afternoon heat gain dropped noticeably.
Yes, with care. Knob-and-tube wiring is common in 1920s Hollywood buildings, and foil is conductive, so we never let it contact bare copper or deteriorated insulation. We route around wiring, use proper fasteners, and flag any wiring that looks damaged. If the foil was previously installed touching knob-and-tube, we address that before anything else.
It changes everything. With no sheathing between the stucco and the stud bays, the wall cavity is directly exposed to the stucco’s moisture path. Non-perforated foil in a wall like this creates a vapor trap. We specify perforated foil or skip foil entirely in favor of dense-pack wall insulation, depending on what the wall needs.
For Hollywood attic roof decks, perforated is usually correct because it allows the assembly to dry outward while still reflecting heat. Non-perforated foil is a vapor barrier and should only be used in walls or crawl spaces where a vapor barrier is actually appropriate, not as a default attic product. For an exact answer, call (855) 382-3451 and we’ll look at your specific roof deck.
