Reflectix Insulation in Sherman Oaks, CA | Aliso Viejo Insulation Co
Reflectix insulation service in Sherman Oaks means one thing most of the year: keeping a 150°F attic from cooking your living space and making your AC run nonstop from July through September. We’re an independent Reflectix service provider, not a manufacturer affiliate, and we’ve spent years pulling failed foil out of San Fernando Valley attics and re-hanging it correctly. If your Sherman Oaks home has foil stapled flat to the rafters, settled blow-in, or duct jackets that have crumbled in the heat, call (877) 352-4780 and we’ll tell you what’s actually going on up there.
Why Sherman Oaks Residents Choose Us for Reflectix Service
Most insulation crews in Sherman Oaks know fiberglass batts. Fewer know what a radiant barrier is supposed to do, and almost none can tell you why a Reflectix roll installed in 1985 is now working against you. We can. Nate Calloway, our owner, has been diagnosing insulation failures in Southern California attics for nearly two decades, and the Reflectix-specific failures we see in Sherman Oaks are familiar territory. We stock genuine Reflectix-brand rolls and perforated foil, and we build the air gap correctly with spacer battens and foil tape, because without that gap, foil isn’t reflecting anything. It’s conducting heat. That’s the difference between us and a crew that just staples shiny stuff up and calls it done.
We’re a full-method insulation contractor with access to eight manufacturer brands, including Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. That matters on Reflectix jobs because sometimes the right answer is Reflectix, and sometimes the right answer is re-leveling the loose fill first or sealing the attic floor. We’ll tell you which one your house needs. Our Reflectix sales & service work covers repair, re-hang, and full replacement, and Sherman Oaks is a core part of our Sherman Oaks service area.
Common Reflectix Insulation Problems We Solve in Sherman Oaks
- Foil stapled flat with no air gap. This is the big one in 1980s-era Sherman Oaks attic retrofits. Reflectix needs a ¾-inch minimum air space between the foil and the roof deck to reflect radiant heat. Stapled tight, it conducts heat straight into the sheathing. We pull it, add spacer battens, and re-hang it so it actually works.
- Crushed and torn bubble-pack from foot traffic. Low-pitch ranch attics around the flatland south of Ventura Blvd get walked on. HVAC techs, cable installers, plumbers. Every trip up there crushes the bubble core and tears the foil facing. Once the reflective surface is compromised, the roll is doing almost nothing. We replace those runs.
- Sagging sheets and staple pull-out after re-roofs. Hillside rebuilds south of the Blvd have complex roof lines where foil was cut and pieced around hips and valleys. Every re-roof loosens staples. The sheets sag, lose their air gap, and drape against the deck. We re-tension and re-hang where the foil is sound, and replace where it isn’t.
- Crumbled duct jackets on sun-baked flex runs. In the 1950s-60s ranches off Van Nuys Blvd, we routinely find flex duct whose foil jacket has literally crumbled in the attic heat, sitting under a few inches of settled loose-fill. Reflectix duct wrap is the right fix here, but the loose fill has to be addressed too or you’re only solving half the problem.
- Delaminated foil facing on older rolls. After 20 or 30 years of Valley heat cycling, the foil facing on bubble-pack can separate from the polyethylene core. Once delaminated, the reflective surface is compromised and the R-value drops. We replace the run with new Reflectix double reflective insulation roll.
Reflectix Service in Sherman Oaks: What Local Conditions Mean for Your Equipment
Sherman Oaks sits in the hottest, most sun-baked eastern stretch of the San Fernando Valley, and the flatland south of Ventura Blvd is full of 1950s-60s ranch tract attics where original blown-in insulation has compacted to roughly half its installed depth. Here’s what that means for a Reflectix call: the effective first move is usually not hanging more foil. It’s re-leveling the loose fill and re-wrapping the ducts whose foil jackets have crumbled in 150°F attic heat. We’ve opened attics off Van Nuys Blvd where the duct insulation jacket had turned to dust and the blow-in was barely covering the ceiling joists — the same issues we address with our Van Nuys Reflectix service. A radiant barrier on top of that helps, but it’s like putting a good roof on a house with no walls. We fix the whole assembly. That’s what separates our Reflectix work in Sherman Oaks from a crew that just sells foil by the roll.
On a 1960s ranch off Van Nuys Blvd in the flat streets south of Ventura Blvd, we opened the attic to find a Reflectix-style foil run stapled tight to the rafters with zero air gap and blown-in insulation settled to half its original depth, plus a flex duct whose foil jacket had crumbled in the 150°F attic heat. We pulled the sagging foil, built spacer battens to restore a true air gap at the rafters, re-hung perforated Reflectix, re-wrapped the duct jacket, and blew the loose fill back to level. The west-facing bedrooms ran noticeably cooler through August. That’s a standard Sherman Oaks job for us, and it’s the reason we always diagnose before we recommend.
Reflectix Models & Products We Service in Sherman Oaks
We work on the full Reflectix lineup you’re likely to find in a Sherman Oaks attic. That includes the Reflectix Double Reflective Insulation Roll, the bubble-pack with foil on both faces that shows up in everything from garage ceilings to crawlspace lids. We also service Reflectix Perforated Radiant Barrier Foil, the vapor-open product you want on roof decks and attics where moisture needs to pass through. And we handle Reflectix Reflective Foil Insulation for duct wrap and HVAC jacket re-wrapping, which is a constant need in older ranch attics around 91403, 91413, 91423, and 91495. When the assembly calls for a vapor-open product, we use genuine Reflectix-brand rolls and perforated foil. For baffles, spacer battens, and foil tape, we use quality aftermarket materials that build the air gap correctly. When foil is sound but mis-installed, we re-tension and re-hang. When the facing has delaminated or the bubble core is crushed, we replace that run.
Reflectix Service Pricing in Sherman Oaks
Reflectix work in Sherman Oaks is priced by the size of the attic and the scope of the repair. A simple re-tension and re-hang of sagging foil in a small ranch attic costs less than a full duct re-wrap plus loose-fill re-leveling plus new radiant barrier on a hillside rebuild. What drives cost: attic square footage, roof complexity, how much of the existing foil is salvageable, whether ducts need re-wrapping, and whether the loose fill needs to be blown back to level. A free estimate includes an attic inspection, a straight answer on what’s salvageable versus what needs replacement, and a written quote. Call (877) 352-4780 for an exact number. Estimates are free and we’ll tell you what we’d do if it were our house.

FAQs – Reflectix Insulation in Sherman Oaks
Because foil without an air gap doesn’t reflect radiant heat, it conducts it. Stapled flat against the roof sheathing, the foil becomes a heat conductor, transferring attic heat into the deck and eventually into your living space. The fix is removing the foil, installing spacer battens to create a ¾-inch minimum air space, and re-hanging it. That’s the most common Reflectix repair we do in Sherman Oaks. Call (877) 352-4780 for a free attic check.
Yes, and in most Sherman Oaks ranch attics it should come first. If your flex duct jackets have crumbled from years of 150°F heat, you’re losing conditioned air into the attic before it ever reaches your rooms. Re-wrapping the ducts with Reflectix Reflective Foil Insulation stops that loss. Then we address the loose fill and, if it makes sense, the radiant barrier. Fix the building, not just the bill.
It depends on the roof assembly. Perforated Reflectix allows moisture vapor to pass through, which is critical in low-pitch roofs where condensation can collect. If you have a low-pitch ranch attic, we spec perforated foil and verify existing ventilation is adequate before adding a barrier. We stock both perforated and non-perforated rolls so the recommendation matches the roof, not whatever’s on the truck.
For concrete-tile roofs on the hillside rebuilds south of Ventura Blvd, we typically use Reflectix Perforated Radiant Barrier Foil stapled to the underside of the rafters with a proper air gap. Perforated product is important here because tile roofs breathe differently than composition shingle, and trapped moisture under tile can damage the deck. The complex roof lines also mean careful cutting and piecing, which is where our experience on hillside Sherman Oaks homes — and nearby Reflectix service in Studio City — pays off.
Not directly. A radiant barrier reduces radiant heat transfer from the roof deck, not air infiltration. If smoke and Santa Ana winds are getting into your living space, the problem is the attic-to-house air barrier, meaning gaps around can lights, top plates, and the attic hatch. We address both on the same call: radiant barrier for heat, air sealing for smoke and wind. Call (877) 352-4780 and we’ll assess both.
