Reflectix Insulation in Commerce, CA | Placentia Insulation
We provide independent Reflectix installation and service across Commerce, including Attic Insulation – Commerce, specializing in reflective foil and radiant barrier work for the city’s mix of mid-century homes and light-industrial buildings. The thing that separates our Reflectix work here: we verify attic ventilation before we staple a single sheet of foil, because Commerce’s low-pitch roofs trap heat in ways a flat-out reflective install can make worse. Alan Whitcomb and the Placentia Insulation crew have been doing this long enough to know when Reflectix is the right call and when you’re better off with blown-in cellulose or fiberglass. Call (855) 773-6429 for a straight answer.

Why Commerce Residents Choose Us for Reflectix Service
Reflectix is not a one-size-fits-all product. It works brilliantly when paired with the right air gap and ventilation path, and it underperforms when stapled up by someone who treats it like wallpaper. That’s the difference you get with a dedicated insulation contractor who stocks the full Reflectix line: Double Reflective Insulation Roll, perforated Radiant Barrier Roof Decking, foil tape, and the stapled attic product. We’re not a generalist handyman squeezing Reflectix work between plumbing calls. We’re Reflectix sales & service specialists who understand how reflective surfaces behave in the inland Los Angeles Basin heat that bakes Commerce every summer.
Alan grew up around older Southern California housing stock, learning how these homes breathe, or don’t. His construction technology background at Fullerton College included coursework on building envelope systems, and that foundation shows up in how we assess a Commerce attic before recommending any radiant barrier, whether that’s here or Reflectix repair in Bell Gardens. We look at soffit vents, ridge caps, existing insulation depth, and wiring first. Then we talk product.
Common Reflectix Insulation Problems We Solve in Commerce
- Foil delamination and bubbling on low-pitch roofs. Commerce’s flat and low-slope roofs bake under summer sun, and attic temperatures can spike past 140 degrees. We regularly see Reflectix foil that has bubbled or separated from its substrate because the original installer skipped ventilation improvements and trapped heat against the foil’s surface. The fix starts with airflow, then new foil.
- Tape failure at seams on 1960s-70s tract homes. Attic temperatures in Commerce swing hard between day and night, which repeatedly expands and contracts seam tape. We see radiant barriers sagging or pulling away from rafters near the intersection of Slauson and Eastern and throughout the older residential blocks. Tension on the foil plus cheap tape always fails eventually.
- Dust and oxidation dulling reflectivity in industrial-adjacent neighborhoods. Commerce is a small, fully built-out industrial city bisected by the I-5, and homes near warehouse corridors collect a fine layer of dust and diesel particulate on exposed foil. Oxidized, dust-coated foil loses much of its reflective performance, especially when installed without a protective facing.
- Foil installed directly over settled blown-in insulation. In stucco apartment attics and older tract homes, we find radiant barrier laid flat over old cellulose with no air gap. That setup traps moisture against the insulation and crushes its R-value. Reflectix needs a reflective air space to do its job; laying it directly on insulation defeats the purpose.
- No ventilation baffles at the eaves. Most 1960s Commerce homes were built with minimal soffit venting, and when a crew staples foil from ridge to eave without baffles, they seal off what little airflow exists. The second floor gets hotter, not cooler. We install baffles as a standard part of any Reflectix retrofit here.
Reflectix Service in Commerce: What Local Conditions Mean for Your Equipment
Commerce combines two building types you rarely see packed this close together: dense blocks of post-WWII tract homes and small stucco apartments from the 1940s through 1970s, plus a large stock of concrete tilt-up warehouses and metal industrial buildings. That mix drives very different Reflectix applications within the same square mile. On the residential side, we’re retrofitting attics over settled or missing insulation in homes where the “second floor is 15 degrees hotter than downstairs” complaint is routine. The flat and low-pitch roofs that define much of Commerce’s housing stock leave minimal attic space, so a radiant barrier has to work in tight clearances with careful attention to the air gap. On the industrial side, we’re quoting metal-building and warehouse thermal upgrades under California energy code, where perforated Reflectix roof decking does double duty as a radiant barrier and condensation control layer. The same product behaves differently in a 1965 stucco tract home near Slauson Avenue than it does in a metal warehouse off Bandini Boulevard, and our recommendations shift accordingly. Most crews only know one of those two applications. We work both every week in Commerce.
Reflectix Models & Products We Service in Commerce
We install and service the full residential Reflectix line: the Double Reflective Insulation Roll, which is the foil-bubble-foil workhorse for walls and tight cavities; the perforated Radiant Barrier Roof Decking, which we specify when a metal or wood roof deck needs a breathable reflective layer; the Attic Radiant Barrier, stapled to rafters with proper standoffs; and the foil tape that seals seams and edges. For any Reflectix retrofit, we use genuine Reflectix foil and tape so the product’s emissivity and reflectivity ratings stay honest. Fasteners, standoffs, and ventilation baffles we source from quality aftermarket suppliers as needed, because those components don’t affect the reflective surface the way off-brand foil does.
Our approach on every job is the same: assess whether the existing radiant barrier can be repaired or retrofitted effectively, or whether the honest fix is full attic insulation replacement. Sometimes the foil is fine and the ventilation is the problem. We’ll tell you which one you’re actually paying for.
Reflectix Service Pricing in Commerce
Reflectix work in Commerce typically lands between $1.50 and $3.00 per square foot installed, depending on the product line and how much prep work your attic needs. A stapled attic radiant barrier with standoffs and taped seams runs lower in the range. Perforated roof decking or a full Double Reflective Insulation Roll application pushes toward the higher end. The variables that move your quote: attic accessibility, whether old foil needs removal, how many baffles we’re adding, and whether we’re topping off your existing insulation at the same time.
| Service | Typical Installed Cost (Commerce) |
|---|---|
| Radiant barrier stapled to rafters, with air gap and taped seams | $1.50 – $2.25 per sq ft |
| Perforated Reflectix roof decking (new or retrofit roof) | $2.00 – $3.00 per sq ft |
| Double Reflective Insulation Roll (walls, tight cavities) | $1.75 – $2.75 per sq ft |
| Ventilation baffle installation (per eave bay) | $12 – $20 each |
| Old foil removal and disposal | $0.35 – $0.60 per sq ft |
Every estimate starts with an attic inspection because the honest price depends on what’s already up there. Call (855) 773-6429 and we’ll come look before we quote anything.

FAQs – Reflectix Insulation in Commerce
It can, but only if your attic has or can get proper ventilation. Flat and low-pitch roofs in Commerce trap heat, and a radiant barrier without an air gap and baffled eaves will underperform and can actually raise attic temperatures. We assess ventilation first, then recommend Reflectix only where it will produce a real cooling-season gain.
No, not directly. Reflectix needs a reflective air space to work, and laying it flat over settled insulation eliminates that air gap and traps moisture. If your Commerce attic has old blown-in material, we either install the foil at rafter level with standoffs or top off and recondition the insulation before any radiant barrier goes in.
That’s one of the most common calls we get in Commerce, and it usually comes down to installation. A radiant barrier stapled without a proper air gap, with failed tape seams, or without eave baffles won’t cut heat gain meaningfully. In homes near Slauson and Eastern, we’ve removed badly installed foil and redone it with standoffs and baffles, and the upstairs bedroom finally matched the downstairs temperature — the same careful approach we bring to Reflectix in Bell. Call (855) 773-6429 and we’ll inspect yours.
The foil itself is durable in dry heat; the weak points are seams and installation details. Attic temperatures in Commerce swing hard between day and night, which stresses tape over time, and dust from nearby industrial corridors can settle on exposed foil and reduce reflectivity. Properly installed with quality tape and adequate clearance, Reflectix performs well here for many years.
Yes. Commerce has a large stock of concrete tilt-up and metal industrial buildings, and we routinely quote Reflectix radiant barrier and roof decking installations for those structures under California energy code, just as we do for Reflectix service in Maywood. Perforated Reflectix works well as a condensation control layer in metal buildings. Call (855) 773-6429 for a free estimate on your commercial space.
