Reflectix Insulation in Sherman Oaks, CA | Thermal Insulation Co
We provide independent Reflectix service across Sherman Oaks, from diagnostic assessments to full foil barrier correction and insulation top-ups. The thing that sets our Reflectix work here apart is straightforward: we fix the air-gap and baffle detailing that Sherman Oaks heat-pocket attics demand before we ever sell you more foil. Call (855) 382-3451 for a free estimate, and we’ll tell you whether Reflectix is actually the right layer for your attic, or whether something else makes more sense.
Our crew has installed and corrected Reflectix foil products in hundreds of San Fernando Valley attics. We know the full Reflectix sales & service line: Double Reflective Insulation Roll, Perforated Radiant Barrier Foil, Reflective Bubble Duct Wrap. We’re not manufacturer-affiliated, so our only loyalty is to what performs in your specific Sherman Oaks home.
Why Sherman Oaks Residents Choose Us for Reflectix Service
Thermal Insulation Co is a dedicated insulation contractor. Insulation is not a side trade for us, it’s the entire job. When we walk into a Sherman Oaks attic, we’re not there to sell one product line. We carry eight brands across three installation methods, which means Reflectix gets recommended only when it earns its place in your home’s thermal stack.
Ruben Castellano, our owner, learned building science fundamentals at East Los Angeles College before he ever picked up a spray rig. He’s spent the better part of two decades diagnosing why homes feel uncomfortable even after previous contractors have been through them. That matters in Sherman Oaks, where mid-century ranch attics and hillside vaulted ceilings each fail differently. We stock genuine Reflectix rolls and seam tape locally for fast turnaround, and we pair them with independent blown-in and baffle materials rather than forcing a single-brand stack. If a room in your house has always been the wrong temperature, there is usually a straightforward reason – and it is worth knowing what it is before spending money on anything.
Common Reflectix Insulation Problems We Solve in Sherman Oaks
- Foil stapled flat against the roof deck with no air gap. This is the most common failure we see in Sherman Oaks. On a 100-degree afternoon, attic air hits 130-140°F. Foil without a gap conducts heat instead of reflecting it. The radiant value collapses to nearly nothing. We re-hang the foil with a true air gap or recommend a different approach entirely.
- Non-perforated Reflectix used as a rafter barrier on vented low-pitch 1950s ranch attics. The flat-grid streets north of Ventura Boulevard are full of these homes. Non-perforated foil traps moisture against the sheathing, and we regularly find deck staining when we open these attics. The fix is perforated foil plus restored eave-to-ridge airflow.
- Dust and soot loading on foil surfaces. Homes near Ventura Boulevard traffic and mature street trees collect a film on Reflectix over a few seasons. That film cuts reflectivity dramatically, sometimes by more than half. We clean and re-tension salvageable foil before recommending replacement.
- Sagging or blown-loose bubble foil. 1950s rafter wood degrades. Staples pull out. Gaps open up where ridge-vent air bypasses the barrier entirely. We see this constantly in older Sherman Oaks ranch attics. Re-stapling into solid wood and re-tensioning the foil restores the barrier’s function.
- Reflectix over cathedral ceilings with no cavity space. The hillside and canyon-edge homes south of the Boulevard have vaulted ceilings with limited insulation depth. Foil alone will not solve those rooms. We pair Reflectix with closed-cell foam or mineral wool where cavity space allows, and we’re honest when foil is the wrong tool.
Reflectix Service in Sherman Oaks: What Local Conditions Mean for Your Equipment
Sherman Oaks sits in a heat pocket of the San Fernando Valley where summer temperatures routinely run hotter than coastal LA. Attic heat gain, not winter cold, dominates the insulation conversation here. That changes how Reflectix should be installed. A barrier stapled flat to a low-pitch 1950s ranch deck traps heat instead of reflecting it. The foil needs a real air gap, and it needs eave baffles keeping the ridge-to-soffit path open. Without those details, you’re paying for shiny foil that does almost nothing.
On the flat streets north of Ventura Boulevard, our technicians routinely find 1950s ranch attics with a few inches of settled original insulation, no baffles, and perforated Reflectix stapled flat against the deck. The homes run hot, the AC runs nonstop, and the homeowner thinks insulation was already done. It was, just wrong. We pull the fouled foil, install eave baffles, re-hang Reflectix with a true gap, and blow in cellulose to bring the ceiling up to code. The upstairs bedrooms finally hold setpoint through a 100-degree afternoon.
The hillside homes off the canyon edges are a different story. Sloped, irregular attics and older construction make every retrofit a custom job. Vaulted ceilings leave almost no cavity space. Reflectix there gets used as a radiant layer under whatever cavity insulation exists, not as the primary barrier. We approach those homes case by case.
Reflectix Models & Products We Service in Sherman Oaks
We work with the full Reflectix sales & service lineup. That includes Reflectix Double Reflective Insulation Roll in 16-inch and 24-inch widths, the double bubble foil used over rafters and under roof decks. We also handle Reflectix Perforated Radiant Barrier Foil for vented attic applications where moisture needs to pass through. For ductwork, we service Reflectix Reflective Bubble Duct Wrap on attic HVAC flex runs.
We use genuine Reflectix rolls and their adhesive seam tape for the barrier layer. But we pair them with independent, code-compliant blown-in and baffle materials rather than forcing a single-brand stack. If existing foil is intact but fouled or gapped, we clean, re-tension, and re-staple before ever recommending full removal. Replacement is the last option, not the first pitch.
Reflectix Service Pricing in Sherman Oaks
Reflectix service in Sherman Oaks varies based on what we find when we open the attic. A simple clean and re-staple of existing foil runs less than a full removal, baffle install, and re-hang. Larger attic retrofits with blown-in insulation added on top cost more. The size of your attic, the condition of the existing rafter wood, and whether we’re adding eave baffles all drive the final number.
What a free estimate includes: we inspect the attic, measure the existing insulation depth, check the Reflectix condition and air-gap detail, and give you a written scope with line-item pricing. No obligation. Call (855) 382-3451 to schedule a visit. We’ll tell you what your attic actually needs, not what’s easiest to sell.

No. We are an independent Reflectix service provider. We install and correct Reflectix products, but we are not manufacturer-affiliated or authorized by Reflectix. That independence is deliberate.

Yes. We stock genuine Reflectix rolls and their adhesive seam tape for the barrier layer. When we pair Reflectix with blown-in insulation or baffles, we use independent, code-compliant materials suited to the application rather than forcing a single-brand stack.
Yes, in most vented attics we can blow cellulose or fiberglass over existing Reflectix that’s properly installed as a radiant barrier. The key is that the foil must have an air gap and the eave vents must remain open. If the foil is stapled flat against the deck or blocking airflow, we correct that first before adding insulation. Call (855) 382-3451 and we’ll tell you what your attic can handle.
We service Reflectix Double Reflective Insulation Roll (16-inch and 24-inch widths), Perforated Radiant Barrier Foil, Double Reflective Foil Insulation with adhesive seam tape, and Reflective Bubble Duct Wrap. If you have a different Reflectix product in your attic, we’ll assess it on site.
Costs depend on attic size, foil condition, and whether baffles or top-up insulation are needed. A clean and re-staple job on an average Sherman Oaks ranch attic runs less than a full removal and re-hang with new baffles and blown-in cellulose. Estimates are free; we give you a written scope before any work starts. Call (855) 382-3451 for an exact quote.
