Reflectix Insulation in San Diego, CA | Woolsey Insulation San Diego
We provide independent Reflectix insulation service across San Diego, from Ocean Beach to El Cajon. What makes our work here different is simple: we know how this product behaves in salt air, sun-blasted attics, and 60-year-old stucco homes. If your Reflectix radiant barrier or reflective insulation isn’t performing the way it should, call (619) 344-8538 and we’ll figure out why. Woolsey Insulation San Diego installs, repairs, and replaces Reflectix products the right way, with written pricing before anything gets touched.
We’re not a manufacturer-authorized shop, and we won’t pretend to be. What we are is a team that’s been inside enough San Diego attics to know exactly where Reflectix shines and where it fails. Our Reflectix sales & service work covers every line the brand makes, and we’re familiar with the failure patterns this climate produces.
Why San Diego Residents Choose Us for Reflectix Service
Glenn Hartley, the owner here at Woolsey Insulation San Diego, picked up his insulation fundamentals at Los Angeles Trade-Technical College before spending nearly two decades working through attics, crawlspaces, and wall cavities up and down Southern California. For years now, he and our crew have been the ones San Diego homeowners call when something feels off, whether that’s a drafty upstairs bedroom in Rancho Bernardo or an older bungalow that’s never had proper R-value in its walls. Glenn is known for being straightforward about what a house actually needs rather than what sounds impressive on a quote sheet.
Good insulation shouldn’t be a mystery. It should just work, and you should understand why. That’s how we approach every Reflectix job. We use genuine Reflectix rolls and matching reflective tape for replacements and new work because off-brand bubble-foil products rarely match the emissivity ratings tested by Reflectix. We repair seams and punctures when the foil layer is intact, but if corrosion or delamination is widespread, replacement is usually more cost-effective than trying to restore an aged radiant surface. You get an honest recommendation, not a sales pitch.
Beyond Reflectix, we also work with seven other leading insulation brands: Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. That means the material recommendation fits the home, not whatever happens to be on the truck.
Common Reflectix Insulation Problems We Solve in San Diego
- Pinprick corrosion on the foil facing. In coastal areas like Ocean Beach and Point Loma, salt-laden air eats through the aluminum facing over time. Tiny holes appear that you’d never notice from a glance, but they cut radiant reflectivity well below factory spec. We see this constantly on older installations.
- Seams opening in inland valleys. El Cajon and Santee get wide temperature swings between day and night. Improperly stapled or taped seams work themselves open during those cycles, allowing convective air loops that rob the product of its intended performance. A quick re-tape fixes it when caught early.
- Compression and draping in older attics. In Clairemont and Allied Gardens, years of storage and foot traffic can compress or drape Reflectix, reducing the airspace the product requires to function as a radiant barrier. Without that airspace, it’s basically just a shiny blanket doing nothing.
- Moisture trapped against duct wrap. When Reflectix is installed against HVAC ducts without a consistent air gap, the reflective surface fails and can trap moisture between the duct insulation and the wrap. This accelerates duct sweating during San Diego’s mild but humid winters.
- Radiant barrier installed flat over ceiling joists. This is the big one. Reflectix needs an air gap to reflect radiant heat. Laid flat, it conducts heat instead. We fix this by reinstalling the barrier taut across rafter faces with proper stapling and fresh tape.
Reflectix Service in San Diego: What Local Conditions Mean for Your Equipment
San Diego’s Mediterranean climate creates an unusual need for Reflectix in west-facing attics that get blasted by late-afternoon sun. In neighborhoods like University Heights and Normal Heights, original 1950s homes often have only R-11 batts and no radiant barrier at all. The afternoon sun pounds those west-facing roof planes for hours, and the attic turns into an oven that radiates heat down into the living space for hours after sunset. That’s a San Diego-specific problem: the coast moderates the air temperature, but the sun load on those older, shallow-pitch roofs is relentless.
What we find in these homes matters for how Reflectix performs. The product needs an air gap of at least 3/4 inch on one side to reflect radiant heat properly. When a 1957 home in North Park had Reflectix stapled directly to the underside of the roof deck with no ventilation considerations, the foil conducted heat right into the attic instead of reflecting it. We reinstalled it taut across the rafter faces with proper stapling and re-taped every seam, then fitted new baffles at the eave vents before blowing in fresh cellulose on the attic floor. The difference in attic temperature was measurable the same afternoon.
Our crew was in Allied Gardens recently replacing compacted fiberglass in a 1963 rancher. The homeowner’s existing Reflectix Double Reflective Insulation had been laid flat over the ceiling joists with no airspace, so it was doing almost nothing. That’s not a product failure. That’s an installation failure. And it’s fixable.
Reflectix Models & Products We Service in San Diego
We work with the full Reflectix lineup: Double Reflective Insulation, Radiant Barrier, Attic Unfaced Reflective Insulation, and Duct Insulation.

We stock genuine Reflectix rolls and matching reflective tape locally, which means faster turnaround for San Diego jobs without waiting on a shipment. No off-brand bubble-foil substitutions. When a repair calls for a specific emissivity rating, we use the material that was tested to hit it.
We service all four lines across San Diego, and we’re the team that will walk through an attic radiant barrier, radiant barrier foil, or attic baffles and ventilation prep job with you before we touch anything.
Reflectix Service Pricing in San Diego

FAQs – Reflectix Insulation in San Diego
Reflectix is not a stand-alone insulator. It’s a radiant barrier, which means it reflects radiant heat but does almost nothing against conductive or convective heat transfer. In San Diego attics, the most effective setup is Reflectix installed with proper airspace to block the sun’s radiant heat, combined with fiberglass or cellulose on the attic floor to slow conductive heat. One without the other leaves a gap in performance. Call (619) 344-8538 and we’ll assess what your attic actually has and what it’s missing.
Reflectix can work in crawl spaces, but coastal humidity accelerates foil corrosion if the material is installed in contact with damp surfaces or without adequate ventilation. In San Diego beach communities, we recommend ensuring the crawl space has proper ground vapor barriers and airflow before installing any reflective product. If the existing foil shows pinprick corrosion, replacement is usually cheaper than trying to patch multiple failing spots.
In Clairemont specifically, two things typically cause early failure: installation without an air gap, which kills the reflective performance from day one, and compaction from storage or foot traffic that drapes the material and eliminates the airspace it needs. Attic heat also degrades the bubble layer over time. If seams are opening or the foil is visibly dimpled, it’s time for a re-install. Call (619) 344-8538 for a free inspection of your attic.
Reflectix Duct Insulation works in San Diego when installed with a consistent air gap around the duct. Without that gap, it can trap moisture against the duct surface and make sweating worse, especially during humid winter months. It’s a useful product for older homes with leaky ductwork in unconditioned attics, but it’s not a universal solution. We’ll tell you honestly whether it fits your duct layout or whether a different wrap makes more sense.
Reflectix is not designed as a primary soundproofing product. It can modestly reduce high-frequency sound when installed as part of a wall or floor assembly with proper air gaps, but it is not a substitute for acoustic insulation like mineral wool or dense-pack cellulose. In dense areas like Pacific Beach or Hillcrest, we typically recommend combining Reflectix’s thermal benefits with a dedicated acoustic layer if sound transfer is the main concern. Call (619) 344-8538 and we’ll walk you through what makes sense for your specific walls.
