Reflectix Insulation in Sherman Oaks, CA | Hollywood Insulation Co
We provide independent Reflectix installation, top-up, and repair across Sherman Oaks. The single factor that shapes all our Reflectix work here: attic decking routinely hits 150°F by mid-morning from June through September, which means foil radiant barrier performs differently in Sherman Oaks than it does almost anywhere else in Los Angeles. If your Reflectix was installed wrong, or has sagged and torn over years of Valley heat, we fix it. Call (866) 605-6949 for an assessment.
Hollywood Insulation Co is not a Reflectix-authorized dealer or manufacturer affiliate. We’re an independent insulation specialist that installs, repairs, and replaces genuine Reflectix products across the San Fernando Valley. Our crews know Reflectix inside out because we work with it daily in Sherman Oaks attics, not because a manufacturer trained us once. See our Reflectix sales & service page for the full scope of what we handle.
Why Sherman Oaks Residents Choose Us for Reflectix Service
Most insulation contractors in Sherman Oaks can staple foil to rafters. Far fewer can tell you why perforated Reflectix facing down on an attic floor is a mistake under blown insulation, or why your foil delaminated from the bubble core after one Valley summer—something we also catch during Reflectix service in Valley Glen calls. That diagnostic depth is what Noel Camacho built Hollywood Insulation Co on. He grew up in East Hollywood and trained through the building construction technology program at Los Angeles Trade-Technical College, where he got serious about building science before most contractors knew the term. When a Sherman Oaks homeowner describes a bedroom that won’t cool below 80°F in July, we don’t guess. We get into the attic and trace the failure: missing air gap, crushed foil, bad seam tape, settled rock wool underneath.
We’re also a dedicated insulation specialist, not a general contractor with an insulation side gig. Every job we take in Sherman Oaks is an insulation job, and we carry three installation methods under one roof: Attic Insulation – Sherman Oaks, spray foam, and blown-in. That matters when Reflectix is part of a larger assembly. If your 1950s ranch needs a radiant barrier plus R-value top-up, we can do both correctly without subbing anything out.
We serve all of Sherman Oaks service area ZIP codes: 91403, 91413, 91423, and 91495.
Common Reflectix Insulation Problems We Solve in Sherman Oaks
Here’s what we actually find when a Sherman Oaks homeowner calls us about a Reflectix problem. Each of these is tied to how this city’s specific housing stock and climate stress foil products:
- Perforated foil on the attic floor, buried under blown insulation. Perforated Reflectix is meant to breathe. Laying it flat on the attic floor and covering it with fiberglass or cellulose crushes the bubble core and dirties the reflective face, which kills emissivity and traps heat in the assembly. We see this a lot in Sherman Oaks ranch attics where someone did a partial DIY job in the 1990s. The fix is pulling the floor foil, deciding whether it’s salvageable, and installing radiant barrier on the rafters where it actually belongs.
- Sagging, torn radiant barrier sheets on 60-year-old rafters. Sherman Oaks has thousands of post-war ranches with original Douglas fir rafters. Decades of 150°F attic summers dry and shrink that lumber. Staples loosen, sheets sag, and gaps open where radiant heat pours through. The foil isn’t the weak link; the wood’s movement is. We re-staple with better fasteners and replace torn runs rather than re-foiling the whole attic.
- Reflectix duct wrap delaminating from its bubble core. Attic-mounted ducting in Sherman Oaks sits in some of the hottest air in the Valley. When foil delaminates from the bubble core, the wrap loses its radiant performance and heat re-radiates into the airstream. Your AC works harder to push 55°F air through 140°F attic space. We inspect seams, re-tape with products that meet fire and moisture standards, and replace only the failed runs.
- Foil stapled tight against decking with no air gap. A radiant barrier needs a 3/4″ air gap to function. When foil is stapled flat against the roof deck, it conducts heat straight through instead of reflecting it. This is the most common installation mistake we correct in Sherman Oaks, especially on low-pitch roofs south of Ventura Blvd. Without the gap, you paid for a radiant barrier that acts like thin aluminum wallpaper.
- Old rock wool settled to a couple of inches underneath a newer Reflectix job. Some Sherman Oaks homes got foil retrofits in the 2000s, but nobody touched the 1950s rock wool under it. Foil alone can’t carry the thermal load of a Valley summer. We top up the R-value below and make the foil perform the way it was designed to.
Reflectix Service in Sherman Oaks: What Local Conditions Mean for Your Equipment
Sherman Oaks sits in the San Fernando Valley’s hottest basin. Summer temperatures routinely top 100°F, and attic decking hits 150°F by mid-morning. On the hillside streets south of Ventura Blvd, where lot sizes shrink and attics get tighter, that heat soaks into low-pitch roof framing and doesn’t leave until well after midnight. Here’s the thing most Reflectix owners don’t realize: foil radiant barrier reflects radiant heat, not conductive heat. When a 150°F roof deck bakes down onto foil that’s missing its air gap, the foil itself becomes a heat conductor, not a reflector. That’s why a correctly installed Reflectix radiant barrier plus blown-in insulation makes a bigger comfort difference in Sherman Oaks than adding R-value alone ever would. If you’re still hot in July, insulation isn’t the last thing to check, it’s usually the first. We’ve seen this exact assembly on a 1958 ranch just south of Ventura Blvd: bare rafters, rock wool settled to about two inches, and a previous Reflectix job stapled flat with no gap. We pulled the compressed foil, installed new perforated Reflectix with proper spacing, added baffles and ventilation prep, and blew in fiberglass to bring the attic up to a modern R-value. All finished before the decking hit 150°F, because that’s the local trade norm here and we plan every Sherman Oaks attic job around it.
Reflectix Models & Products We Service in Sherman Oaks
We work with the full Reflectix line across Sherman Oaks: Double Reflective Insulation Rolls with bubble-pack core, Radiant Barrier Foil in perforated and non-perforated versions, Attic Radiant Barrier kits and foil rolls, and Duct Wrap for reflective duct insulation. We stock genuine Reflectix foil and bubble-pack products for radiant barriers and duct wrap, and we use quality aftermarket tapes, fasteners, and sheathing only where they meet the same fire and moisture standards. When old Reflectix has sagged, torn, or lost its reflective face, we repair what’s sound and replace only the failed runs rather than re-foiling the entire attic—our Reflectix repair in Encino follows the same selective approach. That approach saves Sherman Oaks homeowners real money on homes where the existing foil is 80% functional.
Reflectix Service Pricing in Sherman Oaks
Every Reflectix job in Sherman Oaks gets priced after we look at the attic. What drives cost: attic access and square footage, how much existing foil can be salvaged, whether we’re doing a simple radiant barrier install or a full top-up with blown-in fiberglass, and how early in the morning we need to start to beat the decking heat. Here are the ranges we typically see across Sherman Oaks:
- Radiant barrier repair (re-stapling, seam fixes, small runs): $300 to $700 depending on condition and attic size.
- New Reflectix radiant barrier install on rafters: $1,200 to $2,800 for a typical Sherman Oaks ranch attic.
- Duct wrap repair or replacement: $400 to $1,400 depending on exposed duct length and seam condition.
- Reflectix barrier plus blown-in insulation top-up: $2,500 to $5,500 for the full assembly on a 1950s ranch.

Key Takeaways
- Reflectix radiant barrier only works with a proper air gap, and that matters more in Sherman Oaks than in most LA neighborhoods because attic decking hits 150°F by mid-morning.
- We’re an independent Reflectix service provider, not manufacturer-authorized. We recommend genuine Reflectix material because it performs, not because we have to.
- Most Sherman Oaks Reflectix failures are installation errors that can be repaired without re-foiling the entire attic.
- Older ranches south of Ventura Blvd almost always need an R-value top-up below the foil. Foil alone won’t carry a Valley summer.
- Free estimates include a full attic inspection and a clear read on repair versus replace.

FAQs – Reflectix Insulation in Sherman Oaks
Because the foil is likely missing its air gap or the reflective face is covered in dust from years of Valley heat. A 150°F roof deck radiating down onto foil that’s stapled flat actually conducts heat into your attic instead of reflecting it. Perforated foil that’s been buried under blown insulation also loses nearly all its emissivity. The fix is usually an inspection and targeted repair, not a full replacement. Call (866) 605-6949 for a free attic assessment.
Foil alone is a radiant barrier, not insulation. It reflects radiant heat but does nothing for conductive or convective heat transfer. In a Sherman Oaks summer, where ambient attic air sits above 130°F for hours, you still need an R-value layer. We install Reflectix radiant barrier on the rafters and blow in fiberglass or cellulose below to bring the assembly up to a modern R-value. It’s a two-layer system, not an either/or choice.
We start early. Our crews plan Sherman Oaks attic work for the first available hours, typically beginning before 8 AM, and we hydrate heavily on the roof. It’s not a convenience thing; working in a 150°F attic past noon is physical strain and bad for the materials. Foil tapes and adhesives also apply cleaner on cooler decking. We’ll schedule your job around this, which is why summer installs in Sherman Oaks—and our Reflectix service in Studio City—sometimes book a few days out.
Yes, and this is one of the most common combinations we do in Sherman Oaks. The rock wool from the 1950s has settled to nearly nothing, so we remove or top it up depending on condition, add Reflectix radiant barrier to the rafters with a proper gap, and blow in new insulation below. The foil handles the radiant load from the roof deck, the blown-in handles the conductive load from the attic air. Call (866) 605-6949 for a free estimate on the full assembly.
We do, and low-pitch roofs are where the air gap matters most. Tight attic clearances on Sherman Oaks hillside homes push installers to staple foil flat against the decking, which kills its performance. We work around low clearances by adjusting baffle placement and using the narrowest effective gap that still lets the foil do its job. Every low-pitch install gets a ventilation check before we start.
