Reflectix Insulation in Glendale, CA | Brea Insulation
We provide independent Reflectix installation, removal, and repair across Glendale, from the flats near downtown up into the Verdugo foothills. The short answer: most Glendale homes with existing Reflectix need removal and air sealing before any new foil goes down, because the same heat and rodent pressure that makes radiant barrier useful here also destroys it when it’s installed wrong. We’re an independent contractor, not a Reflectix dealer or authorized service center, so our recommendations are based on what actually holds up in Glendale attics, not on moving product.

Why Glendale Residents Choose Us for Reflectix Service
Insulation is all we do. That narrow focus matters when you’re dealing with a radiant barrier that’s been baking in a 145°F attic for six summers or chewed through by roof rats in the hillside ZIPs. Phil Darnell, our owner, grew up in Brea and spent the better part of three decades working on homes throughout the Brea-Fullerton corridor before building Brea Insulation. He learned early that most homeowners don’t need a sales pitch; they need someone to explain what’s actually happening in their attic and then fix it right. Get the envelope right, and everything else gets easier.
We carry eight manufacturer lines, including Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, so when a Reflectix foil needs to come out, we can put in whatever actually belongs in that specific Glendale house. Sometimes that’s new Reflectix. Sometimes it’s blown-in cellulose or spray foam. The material matches the job, not the other way around. Much of our Reflectix sales & service work in Glendale starts with a removal, because old foil that’s delaminated or covered in rat droppings isn’t reflecting anything.
Common Reflectix Insulation Problems We Solve in Glendale
- Foil bubbling and delamination from attic heat. Glendale summer attics routinely hit 140 to 150°F, and that thermal cycling eventually breaks the bond between the foil face and the bubble core. We see this most often in 1950s and 1960s ranch homes where the original Reflectix was stapled directly to roof decking with no air gap.
- Rat-chewed radiant barrier in hillside attics. In 91208 and 91206, palm rats and roof rats treat exposed Reflectix like nesting material. They shred the foil, drag it into soffit corners, and leave urine and droppings that destroy the reflective surface. This is a removal-and-replace job, not a patch job.
- Moisture trapped behind foil in vented crawlspaces. When Reflectix gets installed over existing soiled batts or against a crawlspace wall without proper ventilation, condensation collects behind the foil and corrodes it. We see this in older Glendale bungalows with original vented crawlspaces from the 1920s and 1930s.
- Dust-covered foil that stopped reflecting. Radiant barrier only works when the shiny surface faces an air gap. Once dust settles on a horizontal attic floor installation, performance drops fast. Homeowners often think the product failed; the real issue is it was installed in the wrong orientation for a dusty Glendale attic.
- Taped seams failing on attic floor barriers. Reflectix tape dries out and releases under years of summer heat. When seams open, the barrier loses continuity, and hot air channels through like the foil isn’t there. We re-tape and sometimes re-run entire sections.
Reflectix Service in Glendale: What Local Conditions Mean for Your Equipment
Glendale’s hillside and canyon neighborhoods, from the Verdugo foothills above 91208 up through Chevy Chase Canyon, combine decades of pre-1978 wood-frame and stucco construction with attic and crawlspace cavities that were never insulated to modern Title 24 levels. Here’s the thing that’s true in Glendale and not in most neighboring cities: the steep roofs over living spaces in 91208 and 91206 create attic cavities that are hard to access, poorly vented, and absolutely loaded with rat traffic. We’ve pulled Reflectix out of Chevy Chase Canyon attics that looked like confetti from a nest-building rat colony. The native palm rats move through the canyons every year, and a shiny foil blanket is irresistible to them. Flatter cities like Burbank or Pasadena don’t carry the same rodent density in their attics. In Chevy Chase Canyon, for example, we removed a rodent-soiled Reflectix radiant barrier from a 1950s ranch home’s attic, air-sealed the top plates and penetrations, and installed a new perforated Reflectix radiant barrier on the roof deck. Attic temperatures came down noticeably, and the rat runs through the foil stopped because there was nothing left for them to shred. That sequence, removal first, air sealing second, new foil third, is the standard for Glendale hillside work.
Reflectix Models & Products We Service in Glendale
We work with the full Reflectix lineup: Double Reflective Insulation Roll, Double Reflective Foil Insulation, perforated Radiant Barrier Foil, and the brand’s insulation tapes and fasteners. When we can, we use genuine Reflectix rolls and tapes for Glendale replacements. When lead times or costs push against us, we source equivalent radiant barrier products from other manufacturers we trust. The installation and air sealing details matter more than the logo on the foil. For roof-deck applications in Glendale, where 140°F plus attic temperatures are routine all summer, perforated foil goes in so moisture doesn’t get trapped against the decking. For horizontal attic floor layering, we position foil facing down over the insulation with a clear air gap if the space allows. We stock common roll widths and tapes locally so most Glendale jobs don’t wait on shipping.
Reflectix Service Pricing in Glendale
Removal of old, soiled, or delaminated Reflectix in Glendale typically runs $1.50 to $3.50 per square foot depending on access, how much rat contamination we’re dealing with, and whether we need to cut foil away from stapled purlins on a steep roof pitch. New perforated radiant barrier installed on the roof deck runs $2 to $4 per square foot on average. Attic floor reflector over existing blow-in adds $1 to $2 per square foot. A full removal plus air sealing plus new barrier on a 1,200-square-foot Glendale ranch home often lands between $4,500 and $9,000. Every estimate includes the specific materials, the removal scope, and what we’ll do about the air sealing that Glendale attics always need.

FAQs – Reflectix Insulation in Glendale
Does Reflectix radiant barrier actually work in Glendale’s hot attics? Yes, when it’s installed as a roof-deck barrier with a proper air gap facing the attic cavity, Reflectix reduces radiant heat gain measurably in a 140°F Glendale attic. But installed flat on an attic floor where dust settles and rats walk on it, performance dies fast. The installation position decides whether it works or not. Call (866) 858-4033 if you want us to look at your attic orientation before you buy anything.
Why is my Reflectix foil bubbling and peeling in my Glendale home? The bubble pack core and foil face separate when the attic cycles between 140°F daytime heat and cooler nights for several summers in a row. Glendale’s long, hot, dry season accelerates this delamination. Once it starts peeling, the barrier loses reflectivity, and the fix is removal and replacement. Call (866) 858-4033 for a removal quote.
Can Reflectix be used in a crawlspace to control moisture? Reflectix is not a moisture control product. In a vented Glendale crawlspace, installing foil against a wall without ventilation traps condensation behind the foil and corrodes it. We only recommend Reflectix in crawlspaces as a thermal break with explicit air gaps and venting, rarely as a moisture solution. If moisture is the problem, air sealing and a proper vapor strategy comes first.
Do rats chew through Reflectix in Glendale hillside attics? Yes, and in 91208 and 91206 it’s one of the most common reasons we remove old radiant barrier. Native palm rats and roof rats shred the foil for nesting and leave it soiled and useless. The fix involves full removal, air sealing entry points, and installing new barrier only after the rat runs are closed. Glendale hillside attics need rodent exclusion first.
Should I remove old Reflectix before adding new insulation? In most Glendale attics, yes. Old, delaminated, and rat-soiled Reflectix blocks air sealing access and prevents new blow-in insulation from making contact with the attic floor. Leaving it in place often creates a trapped-air layer that undermines the new work. Removal is the first step on nearly every Glendale retrofit we do. Call (866) 858-4033 and we’ll tell you straight what needs to come out.
