Reflectix Insulation in Van Nuys, CA | Laguna Hills Insulation
We provide independent Sherman Oaks Reflectix service and coverage across Van Nuys, including the 91405, 91406, 91410, and 91411 ZIP codes. The short answer: if your Reflectix foil was stapled flat against the roof sheathing without an air gap, it’s doing almost nothing in a Van Nuys summer. We diagnose the attic first, then repair or reinstall the foil layer so it actually reflects heat instead of conducting it. Call (866) 393-6041 for a free estimate.
Laguna Hills Insulation has pulled failed and under-performing Reflectix out of San Fernando Valley attics for years. We don’t sell Reflectix as a standalone miracle. We treat it as one layer in a working attic assembly, and in Van Nuys that means pairing it with real ventilation and the right air gap. As an independent contractor, we’re not tied to Reflectix’s marketing claims or any authorized-dealer script. You get the honest version of what this product does under valley heat.

Why Van Nuys Residents Choose Us for Reflectix Service
Most insulation crews in Van Nuys install fiberglass and call it a day. We work with eight manufacturer brands, but we also know when a radiant barrier belongs in the assembly and when it doesn’t. Garrett Lund, our owner, has been diagnosing attic retrofits in Southern California for over two decades. He learned building science the practical way at Saddleback College in Mission Viejo, where the construction technology program drilled in how structures breathe, hold heat, and lose it. That’s the lens we bring to every Reflectix job in Van Nuys.
The right material in the right place does the work. Everything else is just sales pitch.
We’re independent. We don’t represent Reflectix, and we don’t earn a bonus for pushing foil over blown-in insulation. If your Van Nuys attic needs Attic Insulation – Van Nuys with air sealing and cellulose more than it needs a radiant barrier, we’ll tell you that. If the foil you already have just needs re-gapping and re-taping, we won’t sell you a full replacement. Homeowners comparing multiple bids appreciate a straight answer on material selection, and that’s what we give.
Common Reflectix Insulation Problems We Solve in Van Nuys
- Foil stapled directly to the roof deck, no air gap. This is the single most common failure we see in older Van Nuys attics. Without roughly a 3/4-inch air space between the foil and the sheathing, the Reflectix reflects almost nothing. It conducts heat straight off the roof deck and can actually make the attic hotter. We pull the foil, install it to the underside of the rafters with proper spacing, and re-tape every seam.
- Seam and facing delamination from sustained attic heat. Van Nuys attic deck temps routinely run 40 to 60 degrees above outside air in summer. That’s 130 to 150°F at the sheathing. After a few valley summers, cheap foil tape dries out, seams open, and the foil facing starts peeling off the bubble core. We re-tape with genuine Reflectix foil tape or replace the roll if the facer is gone.
- Foil trapping heat in a poorly vented attic. A lot of 1940s and 1950s Van Nuys tract homes have only two gable vents, and someone stapled Reflectix across the deck thinking it would help. In low-ventilation attics, the foil becomes a lid. Heat can’t escape, and on cool winter nights condensation forms against the deck. We fix the ventilation first: baffles, intake and exhaust, then reinstall the foil correctly.
- Dust-and-grit fouling from the dry valley air. Van Nuys sits in the San Fernando Valley, where dry, dusty winds carry fine grit into attics through eave gaps. That dust settles on the reflective surface and cuts its emissivity long before the product itself wears out. A dirty reflective surface is a dull, non-reflective surface. We clean, re-gap, and re-tape when the foil is still sound.
- Reflectix laid on the attic floor instead of the rafters. On the floor, the foil gets walked on, torn, and coated with dust, and it blocks moisture from escaping through the insulation below. This happens more often than you’d think in Van Nuys low-rise apartment buildings where a maintenance person installed it without understanding the product. We relocate it to the rafter line where it belongs.
Reflectix Service in Van Nuys: What Local Conditions Mean for Your Equipment
Van Nuys is a hot inland valley pocket, not a coastal microclimate. The summer attic deck temperature here routinely runs 40 to 60 degrees above the outside air, and the housing stock is dominated by 1940s to 1960s stucco tract homes and low-rise apartments with low-pitch roofs, thin settled insulation, and only nominal venting. That means a radiant barrier in Van Nuys is fighting dry solar heat gain, not marine moisture. The air gap you give it and the intake and exhaust venting you pair it with are what actually decide whether the foil works. On a 1950s stucco tract house off Van Nuys Boulevard in the 91405 ZIP, our crew opened the hatch to find original rock wool settled to roughly R-7 and a previous homeowner’s Reflectix stapled flat against the sheathing with no air gap, its seams dried out from years of valley heat. We pulled the failed foil, cleared and re-baffled the eave vents, added intake and exhaust venting, and reinstalled Reflectix to the underside of the rafters with a true air gap plus fresh foil tape. Attic temps dropped measurably, and the AC stopped short-cycling. In those older Van Nuys attics, the original insulation is often a thin, degraded layer of rock wool or cellulose that has settled to R-7 or less, and the knee-wall attics over garages sometimes haven’t been touched since the 1950s. Reflectix is not the fix for that. It’s a layer you add after the thermal and ventilation issues are addressed.
Reflectix Models & Products We Service in Van Nuys
We work with the full Reflectix line in Van Nuys attics: the Double Reflective Insulation Roll with bubble-core foil in 16-inch and 24-inch widths, the Reflective Foil Insulation with double-sided foil facing, the Perforated Radiant Barrier Roll, and the matching Reflectix foil tape and reflective seam tape used to seal barrier seams. When an assembly needs the product’s rated facing, we use genuine Reflectix rolls and matching tape, not a thinner generic foil. If the existing foil is intact but poorly installed or dust-fouled, we re-gap, clean, and re-tape. When the facer is delaminated or torn, replacement is the honest call, and we stock the standard rolls locally for fast Van Nuys turnaround.
Reflectix Service Pricing in Van Nuys
What drives Reflectix service cost in Van Nuys is the condition of what’s already up there and how much ventilation work the attic needs. A simple re-gap and re-tape job on a small single-story tract house costs less than a full removal and reinstall with new baffles and added exhaust venting. Our estimates are free, and they include an attic inspection, not just a quote over the phone. We’ll tell you whether the foil can be saved or needs replacement, and we’ll show you the ventilation numbers that make the difference in a valley attic. Call (866) 393-6041 and we’ll walk the attic with you before any work begins.
- Re-gap and re-tape existing Reflectix: $450 – $900, depending on attic size and access.
- Remove failed foil, add baffles and venting, reinstall Reflectix: $1,800 – $3,600 for a typical Van Nuys single-story home.
- Full attic assembly: air sealing, blown-in insulation, and radiant barrier: $4,000 – $7,500, depending on square footage and existing insulation condition.

FAQs – Reflectix Insulation in Van Nuys
Because foil stapled directly to the roof sheathing has no air gap, so it conducts radiant heat into the attic space instead of reflecting it back. In Van Nuys summers, where deck temps run 130 to 150°F, this mistake turns the attic into an oven. The fix is re-installing the foil to the underside of the rafters with at least a 3/4-inch air space and sealing every seam with foil tape. Call (866) 393-6041 and we’ll check yours.
No. Reflectix is a radiant barrier, not a thermal bulk insulator. A 1950s Van Nuys home with settled R-7 rock wool still needs blown-in or Spray Foam Insulation in Van Nuys to bring the attic up to a reasonable R-value for the valley. Reflectix works alongside that insulation, not instead of it. We install both.
It can, if the attic is poorly vented and the foil is trapping warm air against the deck. Van Nuys winter nights get cool enough for this to happen, especially in older tract homes with only two gable vents. Adding intake and exhaust venting, plus baffles at the eaves, prevents the condensation problem. That’s a standard part of our Van Nuys Reflectix corrections.
Look for foil that’s sagging, torn, or pulling away from the rafters, seams that have opened, or a dull gray surface covered in dust. If you can see the bubble core separating from the facing, that’s delamination. In a Van Nuys attic, sustained 130°F-plus heat will do that within a few years. We’ll inspect it for free.
No. On the floor, it gets walked on, torn, dust-coated, and it blocks moisture from escaping through the insulation below. It also does very little to stop heat gain from the roof deck. Van Nuys attics need the foil at the rafter line with an air gap to actually reduce radiant heat transfer. Call (866) 393-6041 for an honest assessment.
