Reflectix Insulation in San Bernardino, CA | Thermal Insulation Co
We provide independent Reflectix insulation service across San Bernardino, and the one thing that sets our work apart here is this: we don’t just install foil, we diagnose why the foil already in your attic is failing. San Bernardino’s summer attic temperatures climb past 150°F, which pushes low-end Reflectix bubble rolls to their physical limit. That’s exactly why so many local homeowners call us after a previous fix didn’t hold. Call (855) 382-3451 for a straight answer about your attic.

Why San Bernardino Residents Choose Us for Reflectix Service
We’ve repaired and installed Reflectix service in Muscoy and across decades of San Bernardino tract homes, so we know how their foil facings and low-emissivity surfaces actually behave under 150°F+ attic heat. We’re an independent insulation contractor, not authorized, sponsored, or endorsed by Reflectix. That matters for one reason: when we tell you a Reflectix product won’t fix your problem, we’re not losing a brand bonus. We’re just telling you the truth.
Ruben Castellano, our owner, learned building science at East Los Angeles College before spending the better part of two decades diagnosing why homes stay uncomfortable even after other contractors have been through them. That background shapes how we approach every San Bernardino attic. We don’t start with a product. We start with what’s happening to your heat load, your dust accumulation, and your existing insulation.
Common Reflectix Insulation Problems We Solve in San Bernardino
- Foil delamination and bubbling. The reflective aluminum layer separates from the bubble core after years of 150°F+ attic cycling. Once that happens, the surface stops reflecting radiant heat the way it did when new. We see this constantly in attics off the 215 where original installs date back a decade or more.
- Dust and soot fouling. San Bernardino’s dry air and Santa Ana wind events push dust into open attics. A dusty foil facing drops toward ordinary surface performance. In open-attic installs near Baseline Street and the older northeast neighborhoods, this is the most common reason radiant barrier stops working.
- R-value disappointment. Homeowners buy 16-inch retail Reflectix rolls expecting R-13 or better. Installed as-is, the bubble-core product delivers R-1 to R-3. It works as a vapor barrier or duct wrap, but it was never going to replace your attic’s blown-in R-value. We explain this clearly before touching anything.
- Improper installation over kneewalls and rafters. Foil stapled tight against roof sheathing with no air gap acts as a conductor, not a reflector. In older pre-1970s San Bernardino attics, we routinely find this paired with settled rock wool and rodent nesting, which creates moisture problems no extra foil will solve.
- Foiled-over DIY HVAC duct wraps. Reflectix bubble wrap gets wrapped over duct runs by well-meaning homeowners, but with gaps and kinks it creates condensation points. That leads to drywall staining in converted garage living spaces, which are common across 92404 and 92410.
Reflectix Service in San Bernardino: What Local Conditions Mean for Your Equipment
Here’s the insight most generic insulation pages miss. San Bernardino’s pre-1980 stucco tract homes often have Reflectix or similar foil stapled directly to roof sheathing with no air gap. In this semi-arid heat, that installation actually conducts radiant gain into the attic rather than reflecting it. The foil heats up, the sheathing heats up, and your attic gets hotter than it would with proper ventilation and gapped foil. The fix isn’t more foil. It’s a ventilated radiant barrier with baffles, paired with real R-value that San Bernardino’s older homes never had. Off Baseline Street and the neighborhoods east of the 215, we see this exact condition in 1950s and 60s attics, including homes needing Reflectix in Highland, often alongside original rock wool that has compressed to less than half its installed depth. More foil on top of that only masks the problem.
Reflectix Models & Products We Service in San Bernardino
We service and install the Reflectix product lines that actually make sense in this climate: the Double Reflective Insulation Roll (bubble-core foil, including BP48010 and similar retail rolls), Reflective Foil Insulation (single bubble, R-1 to R-3 class), Reflectix Radiant Barrier Perforated Foil for roof-deck and attic applications, and reflective bubble duct wrap used over HVAC runs. Our Reflectix sales & service approach is straightforward: we install genuine Reflectix rolls where a true radiant barrier layer is the right call, typically on roof decks and rafters over baffles. But we never sell the bubble wrap as a stand-in for R-value. Mass attic performance comes from blown-in insulation and air sealing. If your existing Reflectix foil facing is intact, we’ll repair or re-stretch it. If it’s delaminated or fouled, we’ll replace it and pair the work with a proper R-value upgrade.
Reflectix Service Pricing in San Bernardino
What you’ll pay depends on what’s actually wrong. Re-stretching and relocating intact Reflectix foil costs less than a full radiant barrier replacement, but both are modest compared to a complete attic re-insulation. The bigger line item usually isn’t the foil at all; it’s removing contaminated rock wool or vermiculite, sealing top plates, and blowing in insulation to hit a real R-value target. A free estimate covers exactly that: we inspect your attic, tell you what’s working and what isn’t, and give you a figure for the fix without guessing over the phone. Call (855) 382-3451 and we’ll schedule the look.

FAQs – Reflectix Insulation in San Bernardino
No. Reflectix bubble rolls deliver R-1 to R-3 installed as-is, which is not enough to offset San Bernardino’s weeks of 100°F+ heat. A properly gapped radiant barrier on the roof deck reduces radiant gain, but real attic performance comes from blown-in insulation and air sealing. If your goal is lower summer AC bills, the combination is what works. Call (855) 382-3451 for an attic-specific read.
The aluminum facing delaminates from the bubble core when the attic cycles through repeated 150°F+ highs. San Bernardino’s summer heat accelerates this faster than coastal climates ever will. Once the foil separates, it stops reflecting radiant heat and becomes ordinary surface area. Replacement is the only real fix.
Yes. Pre-1970s attics in San Bernardino sometimes contain vermiculite, which can test positive for asbestos. Any attic with old rock wool or vermiculite gets tested before we disturb it. That’s standard practice on our work here, not an add-on.
Sometimes, but not as an R-value solution. Reflectix bubble wrap works as a vapor barrier or duct wrap in tight spaces where batt or blown-in won’t fit cleanly. For converted garages in 92404 and 92410, the bigger issue is usually the uninsulated walls and ceiling, which need actual insulation, not foil, though we also offer Reflectix in Rialto for appropriate applications. We’ll tell you which is which.
A properly gapped and perforated Reflectix radiant barrier won’t trap moisture when installed with baffles and adequate ventilation. Roof warranty concerns depend on your roofing manufacturer’s terms and the installation method, which we review before we start. For most San Bernardino homes, the bigger moisture risk is the existing unvented foil already stapled flat to the sheathing. Call (855) 382-3451 and we’ll assess what you have.
