Reflectix Insulation in North Hills, CA | Thermal Insulation Co
Reflectix radiant barrier service in North Hills means something specific here: we install, repair, and replace reflective foil in attics that routinely hit 150°F in summer. We also offer Reflectix repair in Van Nuys for homeowners just south of us. Thermal Insulation Co is an independent insulation contractor, not a Reflectix affiliate, and we’ve worked in hundreds of Valley tract homes where the original insulation never matched the climate. If your upstairs rooms bake all afternoon, call (855) 382-3451 and we’ll tell you whether Reflectix is actually the right fix.
North Hills sits in the hottest part of the San Fernando Valley. That changes how radiant barrier should be installed, where it fails first, and what it costs to fix. We cover the 91343 and 91393 ZIP codes with crews who know these low-pitch roofs and tight attic hatches. Whether you need a full Reflectix sales & service install or a repair on foil that’s seen too many Valley summers, we start with an attic inspection, not a sales pitch.
Why North Hills Residents Choose Us for Reflectix Service
Ruben Castellano, our owner, grew up in Montebello and studied building science at East Los Angeles College before he ever picked up a spray rig. He’s spent nearly two decades diagnosing why homes feel wrong, and in North Hills the answer is usually above your ceiling. We don’t guess. We open the attic hatch, check what’s actually up there, and tell you straight whether Reflectix radiant barrier will solve your problem or whether you need something else first.
We’re a dedicated insulation contractor serving the North Hills service area with one trade and one focus. That matters when you’re choosing between radiant barrier, blown-in fiberglass, or spray foam. Because we stock eight brands including Reflectix, Owens Corning, Rockwool, and Icynene, our recommendation is driven by your roof pitch, your attic ventilation, and your cooling bills, not by whatever single product we happen to carry. Most jobs here are re-insulation on 1950s-to-1970s ranches where the original batts are doing almost nothing.
We use genuine Reflectix products and compatible accessories like foil tape and staples, so repairs hold up through August heat waves. Response time is fast, estimates are free, and we’ll show you photos of what we found before we quote a dollar.
Common Reflectix Insulation Problems We Solve in North Hills
- Foil delamination from extreme heat: Attics in North Hills regularly exceed 150°F in summer. Over years, that heat breaks down the adhesive bonding on Reflectix Double Reflective Insulation, and the shiny layer starts flaking off. Once the foil loses its reflective surface, it’s not doing its job. We inspect for this on every radiant barrier call in 91343 and 91393.
- Moisture trapped between foil and roof deck: Many postwar tract homes here have low-pitch composition roofs with marginal ventilation. When Reflectix is stapled tight to the underside of the roof deck without an air gap, warm moist air condenses behind it. That leads to mold and sagging foil. We see this pattern all over North Hills and it’s usually an installation issue, not a product defect.
- Rodent damage to the insulation beneath: Rats and mice love Valley attics, especially in older ranch homes along Sepulveda and the surrounding corridors. They chew through batt insulation and nest between joists, compressing whatever R-value was left. When we install Reflectix over that mess, it doesn’t fix the problem underneath. We remove the contaminated material first.
- Poor seam sealing and edge gaps: Radiant barrier only works when it forms a continuous reflective surface. In tight, low-pitch North Hills attics, installers often skip taping seams or leave edges flapping. That lets convective heat move right through the gaps. We use Reflectix Reflective Foil Tape on every seam and staple pattern that matches the manufacturer’s spec.
- Compressed original fiberglass batts: The 1950s-to-1970s housing stock in North Hills often still has original R-11 batts, and after 50 or 60 years they’re matted down to nothing. Adding Reflectix over dead insulation is a band-aid. We usually recommend removing or topping off the existing material before the radiant barrier goes in.
Reflectix Service in North Hills: What Local Conditions Mean for Your Equipment
North Hills has a particular problem that homeowners in coastal ZIP codes never face: the low-pitch composition-shingle roofs on our postwar tract homes don’t breathe. Most were built with minimal or no ridge vents, and attic temperatures climb fast. That heat doesn’t just make upstairs rooms miserable. It also shortens the life of Reflectix foil, because the adhesive holding the reflective layer together breaks down under sustained 150°F-plus conditions. This isn’t a product flaw. It’s a local climate reality.
If a room in your house has always been the wrong temperature, there is usually a straightforward reason, and it is worth knowing what it is before spending money on anything. In many North Hills homes we inspect, the reason is inadequate ventilation paired with radiant heat gain through the roof deck. Reflectix can work well here, but not as a standalone fix. We frequently pair radiant barrier with baffle and vent upgrades so the foil isn’t trapping moisture against a hot roof deck. On a job in the Sepulveda corridor, our crew opened a 1960s ranch with original R-11 batts that rodents had compressed and contaminated. We removed the damaged material, air-sealed the attic floor, installed Reflectix radiant barrier on the roof deck, and added baffles. The result was a nearly 30°F drop in attic temperature on a 105°F day.
Reflectix Models & Products We Service in North Hills
We install and repair the full Reflectix line that makes sense for Valley attics: the Double Reflective Insulation Roll, the R-21 Attic Wall Radiant Barrier, and the Reflective Foil Tape and Insulation Staples used for proper fastening. On existing installations, we assess whether a targeted section can be repaired or whether the foil is compromised across enough area that replacement is the honest recommendation. If large sections show delamination or rodent damage, replacement usually costs less than repeated patch jobs. We keep genuine Reflectix material and compatible accessories on our trucks for fast turnaround across North Hills and nearby communities, so most radiant barrier repairs don’t require waiting on a warehouse order. That includes Valley Glen Reflectix service calls when speed matters.
Reflectix Service Pricing in North Hills
Radiant barrier work in North Hills is priced by attic square footage and the condition of what’s already up there. A simple Reflectix install over accessible joists on a typical 1,200-square-foot ranch generally runs between $900 and $1,800. Full removal of damaged insulation, air-sealing, vent upgrades, and new radiant barrier on a larger home can run $2,500 to $4,500. Repair work, like re-taping seams or replacing a torn section, often comes in under $400 depending on access.
What drives the cost in this area: roof pitch (low-pitch attics are harder to move around in), the amount of existing insulation that needs attention first, and whether baffles or ridge vents need to be added. Every free estimate includes a photo walkthrough of your attic and a written quote before we do any work. Call (855) 382-3451 and we’ll schedule a time that fits your week.

FAQs – Reflectix Insulation in North Hills
Yes, when installed with an air gap and proper ventilation. Reflectix reflects radiant heat rather than absorbing it, which is exactly what a 150°F attic needs. But in North Hills’ low-pitch tract homes, the foil needs space between itself and the roof deck to perform. Stapled tight against the sheathing, it can trap moisture and degrade faster. We’ll show you what’s possible in your specific attic before you spend anything.
You can install it on the roof deck above existing insulation, but you should not lay it flat over batts on the attic floor. Reflectix works as a radiant barrier, not as a thick conductive insulator. Laying it on top of floor insulation traps moisture and does almost nothing for heat. In North Hills attics with original compressed fiberglass, we usually remove or top off the old material first, then install the radiant barrier where it actually does its job.
Look for flaking foil, dull gray patches where the shiny surface used to be, sagging sections, or condensation stains on the underside. If you can reach the attic safely, check seams for gaps where the tape has peeled. If your upstairs rooms are warming up again even though the foil is still there, it’s likely delamination from years of Valley heat. Call (855) 382-3451 and we’ll inspect it and tell you whether repair or replacement makes more financial sense.
Radiant barrier installation itself generally doesn’t require a building permit in Los Angeles, since it’s not structural and doesn’t modify the building envelope’s electrical or plumbing systems. However, if we’re adding ventilation like ridge vents or eave baffles, that can trigger a permit depending on scope. We handle the paperwork when it’s needed and we’ll tell you upfront whether your job requires it. Call (855) 382-3451 for a straight answer on your specific roof.
Reflectix addresses radiant heat gain, which is the primary problem in Valley attics. Spray foam addresses air leakage and conductive heat loss, which matters more in colder climates or when you’re sealing the entire attic envelope. In North Hills, radiant barrier is often the better first step because it’s less expensive and directly targets the summer cooling load. Some homes benefit from both: a radiant barrier on the roof deck plus air-sealing at the attic floor. We’ll give you an honest recommendation based on your attic, not our inventory.
