Reflectix Insulation in San Fernando, CA | Hollywood Insulation Co
We provide independent Reflectix radiant barrier installation and repair across San Fernando, CA, including both 91340 and 91341. What makes our Reflectix work here different is knowing how this product behaves inside the mid-century bungalow attics that define this city, where summer roof deck temperatures routinely push past 140°F and original framing demands clearance checks before any foil goes up. Call (866) 605-6949 for a free estimate, and we’ll tell you straight whether your attic needs Reflectix, blown-in insulation, or both.
Why San Fernando Residents Choose Us for Reflectix Service
We’ve installed Reflectix in North Hills and throughout more San Fernando Valley attics than most contractors see in a career, and the tight, low-clearance attic spaces off Maclay Avenue and San Fernando Road are familiar ground. Our crew knows which Reflectix product holds up in a 91340 bungalow with original eave venting and which one fails when stretched across a low-pitch ranch roof. Noel Camacho, our owner, learned building science through the construction technology program at Los Angeles Trade-Technical College before most contractors knew the term, and he’s spent two decades diagnosing the real reason a Valley room refuses to cool: attic bypasses, missing blocking, and radiant barriers that were never installed to Reflectix spec in the first place. We’re an independent contractor, not a manufacturer rep, so our recommendation comes down to what your attic actually needs.
Common Reflectix Insulation Problems We Solve in San Fernando
Here’s what we find when we open up attics across San Fernando, and how the local housing stock and climate contribute to each failure:
- Foil delamination and bubbling on hot roof decks. San Fernando’s low-pitch attics turn into ovens from June through September, and Reflectix stapled directly to a roof deck that exceeds 140°F can delaminate, separating the foil from the bubble core and killing the reflective surface. We see this most often in homes where the original installer skipped an air gap or used the wrong fastener pattern.
- Sagging and gapped barriers between rafters. Too much slack at install and generic tape that bakes brittle in Valley heat create gaps where hot attic air bypasses the barrier entirely. Radiant performance depends on a continuous, intact surface; a sagging panel with peeling seams is doing almost nothing.
- Moisture staining and trapped condensation along the bottom foil edge. In San Fernando’s older 1940s and 1950s bungalows with original venting and knob-and-tube wiring, barriers installed without proper baffles or eave-to-ridge ventilation prep trap moisture, staining the foil and eventually degrading the bubble core.
- Crushed or torn panels at the attic hatch and along HVAC duct runs. Repeated service visits and older flex duct contact puncture the bubble core, creating hot spots the homeowner never sees until a room won’t cool no matter the thermostat setting.
- Failed seams from non-reflective tape. Reflectix performance depends on sealed seams, and we regularly find barriers where the original installer used plain duct tape that lost adhesion after one San Fernando summer. Reflective foil tape spec’d for the product is the only thing that holds.
Reflectix Service in San Fernando: What Local Conditions Mean for Your Equipment
San Fernando’s 91340 core and nearby Reflectix service in Shadow Hills areas have an unusually high concentration of wood-framed attics with original knob-and-tube or first-generation wiring. That fact shapes every Reflectix install we do here, because a radiant barrier laid over live knob-and-tube is a fire risk, not an energy upgrade. Before we staple a single foil panel, we inspect the attic wiring, confirm clearances, and correct any venting deficiencies. A lot of the tight attics around the older blocks near San Fernando Road also have first-generation eave vents that were undersized when the house was built, and adding a radiant barrier without fixing that ventilation just moves the heat problem instead of solving it. This inspection step rarely comes up in newer Valley tract homes, and it’s the reason we don’t hand out drive-by quotes without looking at the attic first.
Reflectix Models & Products We Service in San Fernando
We install and repair the full Reflectix line most common in San Fernando attics: the Double Reflective Insulation Roll in 16-inch and 24-inch widths, the R-21 Attic Wall Radiant Barrier, Reflectix Reflective Foil Tape for seaming and edge sealing, and Reflectix Radiant Barrier Roof Decking panels where the framing allows. We stock genuine Reflectix rolls, tape, and fasteners locally so turnaround in San Fernando is fast, not dependent on a special-order wait. When an existing barrier is delaminated or crushed beyond repair, we recommend replacing that section rather than patching, because a radiant barrier only works as a continuous surface. See our full Reflectix sales & service page for product details.
Reflectix Service Pricing in San Fernando
Reflectix radiant barrier installation in San Fernando typically runs $1.50 to $2.75 per square foot of attic area, including foil tape at seams and edge sealing. Repair work, such as replacing a delaminated panel or re-taping failed seams, usually falls between $350 and $800 depending on attic access and how much of the existing barrier needs to come out. A full Reflectix barrier combined with blown-in attic insulation in a standard San Fernando bungalow generally lands between $2,200 and $5,500 depending on attic size, framing, and whether we’re adding baffles or correcting venting first. Our free estimate includes the attic inspection, a written scope, and a straight answer on whether radiant barrier alone will actually solve your heat problem or whether your money is better spent on insulation first.

FAQs – Reflectix Insulation in San Fernando
No, not directly against the deck. Reflectix needs an air space facing the foil side to function as a radiant barrier, and in San Fernando’s low-pitch attics where roof deck temperatures exceed 140°F, stapling it flat against the deck not only kills performance but accelerates delamination. We’ll check your rafter spacing and venting first, then install it with the correct standoff or recommend the right product for your specific roof pitch. Call (866) 605-6949 and we’ll assess your attic.
It doesn’t stop the project, but it does add a required first step. We won’t staple any Reflective foil over live knob-and-tube wiring, so the install begins with a clearance and wiring inspection. In most cases we can work around the wiring safely with proper standoff and spacing; if the wiring is too degraded to work near, we’ll tell you before any foil goes up.
Radiant barrier reflects radiant heat from the sun-baked roof deck, but it does not stop conductive heat transfer the way blown-in insulation does. Most San Fernando bungalows with original or thin attic insulation need both: a radiant barrier to knock down the summer roof deck load and blown-in insulation to slow the heat that still comes through. We’ll measure your current R-value and give you a straight recommendation. Call (866) 605-6949 for an attic assessment.
We use Reflectix Reflective Foil Tape spec’d for the product at every seam and edge, and we also provide Reflectix service in Van Nuys with the same care, installing panels with the right tension so they don’t sag as the attic heat cycles. Generic tape fails after one Valley summer because it wasn’t built for sustained temperatures over 130°F; the right foil tape won’t peel when it’s applied to a clean, dry surface with proper overlap.
Yes. Summer attic temperatures in San Fernando routinely exceed 140°F by midday, so we schedule all attic work for early morning arrival, typically between 7:00 and 8:00 AM. Attics are much safer to work in before the sun loads the roof, and the install quality is better when our crew isn’t working in 140-degree heat. Call (866) 605-6949 to schedule a morning visit.
