Reflectix Insulation in San Fernando, CA | Even Air Insulation
We provide independent Reflectix service across San Fernando, with a focus on radiant barrier installation and repair in the flat-roof, low-ventilation attics that define this city’s older housing stock. The thing that makes our Reflectix work here different is simple: in San Fernando, foil alone doesn’t fix a 150°F attic. Ventilation does. That’s the conversation we have on nearly every estimate.
Even Air Insulation carries Reflectix Double Reflective Insulation Rolls, perforated radiant barrier foil, and the tape and fasteners that go with them. We’re not authorized by Reflectix and we don’t claim to be. We’re a Reflectix sales & service contractor who installs their materials when they’re the right fit for the space, which in San Fernando usually means pairing them with baffles, ridge vents, or soffit intake work. If you’re dealing with an attic that’s blistering by 10 a.m., call (855) 362-0195 and we’ll tell you what’s actually going on up there.
Why San Fernando Residents Choose Us for Reflectix Service
Nelson Quirarte, our owner, studied building construction technology at Los Angeles Trade-Technical College and has spent the better part of two decades doing insulation work across the L.A. basin. He’s walked enough San Fernando attics to know what happens when someone staples reflective foil tight to a hot roof deck and calls it done. That’s exactly the kind of job we get called in to correct.
What sets us apart is that we don’t stock one product and push it on every house. We work with eight manufacturers, including Reflectix in North Hills, and we prescribe materials based on what the attic actually needs. On a San Fernando flat-roof home with no venting, Reflectix might be part of the answer. It’s rarely the whole answer. We’ll tell you that before we quote you, not after. That candor, plus same-week scheduling across 91340 and 91341, is why homeowners call us when a previous contractor’s radiant barrier job didn’t lower their cooling bill at all.
Common Reflectix Insulation Problems We Solve in San Fernando
Here’s what we typically find when someone calls us about a Reflectix installation that isn’t performing:
- Foil delamination from direct roof-deck contact. In San Fernando’s unvented flat-roof attics, summer temperatures routinely pass 150°F. When Reflectix bubble foil is stapled directly to the underside of the roof deck with no air gap, the adhesive layer between the foil and the bubble core breaks down. The foil peels, bubbles, and loses almost all reflective performance. We see this constantly in post-war stucco homes near the downtown core.
- Perforated foil installed wrong-side down or taped shut. Reflectix perforated radiant barrier is designed to let moisture pass through. When it’s installed with the perforations facing the wrong direction or someone seals the seams with solid tape instead of leaving them permeable, condensation gets trapped against the roof deck. In San Fernando’s big day-night temperature swings, that moisture cycles daily and degrades both the foil and the framing over time.
- Crushed bubble foil between rafters. The R-value of Reflectix depends almost entirely on the trapped air gap on either side of the material. We’ve opened attics in 1940s tract homes where the foil was compressed between purlins or pushed flat against the sheathing during install. At that point it’s doing thermal work roughly equivalent to a single sheet of aluminum foil. Performance near zero.
- Foil tape adhesive failure on low-slope roofs. Along the Pacoima Wash edge, we see seams that were taped during fall installs holding fine until the first 105°F afternoon. The repeated expansion and contraction of the roof deck eventually causes the adhesive to let go. Once the seams open, the barrier’s continuity is broken and heat finds its way through.
- Radiant barrier installed without any venting whatsoever. This is the big one in San Fernando. Some of these older flat-roof homes have dead-air attics with zero intake and zero exhaust. Installing Reflectix in that space is like putting a reflective blanket inside an oven. The foil bounces heat around, but without airflow to carry it out, the attic still cooks. The foil didn’t fail. The design did. We fix both.
Reflectix Service in San Fernando: What Local Conditions Mean for Your Equipment
Here’s a checkable fact that shapes every Reflectix job we do in San Fernando: the flat-roof homes near the downtown core and along the Pacoima Wash edge regularly hit 150°F or higher in the attic by mid-morning in July, while similar homes two blocks away in Burbank stay 20 to 30 degrees cooler at the same hour. San Fernando sits lower and flatter on the Valley floor, with less tree canopy and more direct sun exposure than its neighbors to the east. The housing stock compounds it. Most of these are pre-1980 homes with original minimal insulation, little to no attic ventilation, and roof pitches so low that standard ridge venting doesn’t move much air on its own.
What this means for a Reflectix owner is straightforward: the product’s rated performance assumes an air gap and some degree of airflow. A radiant barrier in a dead-air 150°F attic can still reduce heat gain, but the room below won’t feel the difference if the superheated air has no path out. That’s why our Reflectix work in San Fernando almost always includes baffle installation, soffit intake clearing, or a ventilation upgrade. The foil reflects heat. The venting removes it. Without the second half, the first half is largely academic.
Reflectix Models & Products We Service in San Fernando
We install and repair the full Reflectix service in Van Nuys and San Fernando lineup that applies to residential attics: the Double Reflective Insulation Roll with the bubble core, the perforated Radiant Barrier Foil, the Attic Radiant Barrier rated at R-21 in a proper assembly, and the matching reflective foil tape and fasteners. When Reflectix isn’t available in a specific width for a San Fernando low-slope job, we’ll substitute a comparable ASTM-rated radiant barrier rather than make you wait or pay for a custom order. We carry common widths locally for fast turnaround.
OEM versus aftermarket matters in one specific situation: exposed seams. If the tape is visible in a finished attic or the seams run through a conditioned access area, we use genuine Reflectix foil tape so the reflectivity and adhesive hold match the original install. Hidden seams in unconditioned dead-air spaces, we’re comfortable using an ASTM-rated equivalent. We’ll tell you which is which before we start, and we’ll tell you if radiant barrier alone won’t solve your heat problem.
Reflectix Service Pricing in San Fernando
Reflectix service in Shadow Hills and San Fernando typically runs from $1.50 to $3.00 per square foot for materials plus installation, depending on whether it’s a new radiant barrier install or a repair of failed foil. A correction job, where we’re also adding baffles or venting, lands higher because we’re fixing the airflow problem, not just re-stapling foil. Most of our San Fernando customers see the work pay for itself in one or two full cooling seasons.
A free estimate from us includes an attic inspection, an honest read on whether Reflectix alone will do the job, and a line-item quote with no pressure. If your attic’s already 140°F before noon, that’s usually all the data we need. Call (855) 362-0195 and Nelson will walk you through what he’s seeing up there.

FAQs – Reflectix Insulation in San Fernando
Does Reflectix radiant barrier really work in a San Fernando flat-roof attic that hits 150°F? It only works if the attic has an air gap between the foil and the roof deck plus actual ventilation moving air through the space. Foil alone in a dead-air 150°F attic reflects some heat but doesn’t lower room temperature meaningfully without intake and exhaust airflow. That’s the combination we install. Call (855) 362-0195 for a quick attic assessment.
My San Fernando home has original 1970s batt insulation and a low-slope roof – can I just add Reflectix over it? No. Disintegrated 1970s batt has almost no R-value, and laying Reflectix over it addresses only radiant heat, not conductive heat gain through the ceiling. In San Fernando’s climate, you’ll need the old batt removed or topped up, then a radiant barrier installed with an air gap, then ventilation. Any contractor who tells you foil alone will fix an under-insulated San Fernando attic is guessing. We’re not guessing.
Why does my neighbor’s Burbank house stay cooler than my San Fernando home when we both have Reflectix? Burbank runs 5 to 10 degrees cooler than San Fernando on the hottest afternoons because of its slightly different elevation and air movement off the Verdugos, and many Burbank homes have more attic ventilation than San Fernando’s flat-roof stock. If your neighbor’s house also has ridge or gable venting and yours doesn’t, that’s the difference. The Reflectix is probably fine. The airflow isn’t.
What Reflectix product should I use on a low-slope roof deck in San Fernando? Perforated Reflectix Radiant Barrier Foil with a true 3/4-inch air gap using furring strips or baffles, plus intake soffit vents and exhaust venting. On a low-slope deck, we often pair it with a ridge vent or low-profile powered vent because natural convection moves slower without much pitch. That combination is what actually drops attic temperatures on 100°F San Fernando afternoons.
How do I know if my existing Reflectix radiant barrier has failed in my San Fernando attic? Three signs: you see peeling or bubbling foil when you look up at the roof deck, the tape seams have lifted and you can see daylight or gaps along them, or the attic is still 140°F to 150°F by mid-morning even with the foil in place. Any one of those is worth a quick inspection. We’ll tell you if the foil failed or if the ventilation was never right in the first place, and fix whichever one is the actual problem.
