Reflectix Insulation in Highland, CA | Thermal Insulation Co
Reflectix radiant barrier service in Highland comes down to two things: knowing how the foil performs when attic temperatures climb past 150°F, and knowing how to seal it tight enough that Santa Ana smoke doesn’t slip through. We’re Thermal Insulation Co, an independent Reflectix specialist serving Highland, Reflectix in San Bernardino, and the surrounding foothill communities. We install, repair, and replace reflective insulation in older tract homes throughout 92346. Call (855) 382-3451 for a free estimate.

Why Highland Residents Choose Us for Reflectix Service
Reflectix is one of eight brands we carry, and we stock it for a specific reason: no other radiant barrier handles the double threat Highland throws at an attic quite like it. Reflective foil, bubble insulation, and radiant barrier products work by reflecting heat rather than absorbing it. That matters in Highland, where summer sunlight pounds roofs for months and attic temperatures regularly exceed 150°F.
We’re a dedicated insulation contractor, not a handyman service that occasionally touches attics. Ruben Castellano, our owner, learned building science fundamentals 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. When we walk a Highland attic, we’re looking for the same things he looks for: where heat is getting in, where smoke will get in next fire season, and whether the existing Reflectix is actually doing its job anymore.
We use genuine Reflectix products for every radiant barrier job. No knockoff foil, no mismatched tape. And because we carry competing brands across our material lineup, we’ll tell you honestly if Reflectix is the right fit for your attic, crawl space, or ductwork – or if another material makes more sense for your specific situation.
Common Reflectix Insulation Problems We Solve in Highland
Here’s what we find when we open up attics across Highland’s older housing stock:
- Foil delamination from extreme heat. Reflectix installed in attics that regularly exceed 150°F can start to break down at the foil-to-bubble bond. In Highland’s semi-arid summers, this is the single most common failure we see. The reflective surface dulls, the layers separate, and the product stops reflecting radiant heat effectively.
- Perforated panels clogged with dust and ash. Santa Ana winds push fine dust through attic vents, and wildfire season adds ash to the mix. Perforated Reflectix is designed to breathe, but Highland’s wind-driven particulate load can clog those perforations, reducing reflectivity and trapping that smoke smell inside the attic.
- Sagging or loose panels. Inadequate fastening is common in older installs. Sagging creates gaps between the foil and the roof deck, which compromises the reflective air space that makes radiant barriers work. We see this constantly in 1960s and 1970s ranch homes where original Reflectix was stapled without enough support.
- Moisture trapping in crawl space applications. Highland gets occasional winter rain, and when Reflectix is installed in a crawl space without proper vapor barrier integration, moisture gets trapped against the foil. That promotes mold growth and degrades the product far faster than heat or wind.
- Smoke infiltration through unsealed seams. Reflectix only blocks radiant heat if the panels are continuous and sealed. During wildfire season, gaps at seams and penetrations let smoke get pulled into the home through the attic. This is a fire-season-driven failure we hear about from Highland homeowners every year.
Reflectix Service in Highland: What Local Conditions Mean for Your Equipment
Highland sits at the base of the San Bernardino Mountains on the hot, dry east side of the Inland Empire, not far from communities where we also provide Reflectix in Redlands. That position creates a very specific set of demands on radiant barrier insulation that you won’t find in coastal cities or even neighboring high-desert communities. The heat gain in summer is the obvious one, but the smoke intrusion pattern during Santa Ana events is what makes Highland attics genuinely different.
During the worst wind events, homes off Cypress Street and throughout the older tracts east of the 210 take on fine ash and dust through every gap in their thermal envelope. A radiant barrier that is reflective but not sealed does half its job. We’ve walked attics where the Reflectix was still shiny but gaps at the eaves let smoke pour in – the homeowner could smell it in the living room, and the attic smelled like a campfire for weeks. That’s why we approach Reflectix work in Highland as a sealing job first and a reflective job second, just as we do with Reflectix service in Loma Linda. The foil has to reflect the heat, yes, but the seams, penetrations, and edges have to be tight enough that smoke season doesn’t turn your attic into a chimney. This dual requirement – reflect and seal – is what separates proper Highland radiant barrier work from a generic install.
In a 1960s ranch home off Cypress Street in Highland, we found Reflectix radiant barrier panels sagging and coated with ash from the previous fire season, causing attic temperatures to spike above 160°F. We removed the degraded foil, air-sealed all penetrations, reinstalled perforated Reflectix with reinforced fasteners, and added baffles to improve ventilation. The homeowner reported a 15°F drop in attic temperature and noticeably less smoke odor during the next Santa Ana event.
Reflectix Models & Products We Service in Highland
We work with the full Reflectix product line, and we stock the items most relevant to Highland homes so turnaround stays fast. The Reflectix Double Reflective Insulation Roll is the workhorse for attic and wall applications, ranging from R-3.7 to R-21 depending on the installation assembly. We also install Reflectix Radiant Barrier Attic Foil – both perforated and non-perforated – for roof deck and rafter applications. Reflectix Reflective Bubble Insulation is what we use for crawl spaces and duct wraps, where the bubble structure provides both reflection and a small insulating air gap. And we keep Reflectix Insulation Tape and Fasteners on hand because seams and attachment points are where Highland’s heat and wind do their damage.
When repair is feasible, we repair. Re-securing sagging panels or cleaning ash from perforated foil with the right tools can extend the life of a good install. But when the foil is delaminated or the surface has degraded from years of 150°F-plus attic temperatures, we recommend full replacement with upgraded fastening and sealing. 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.

Reflectix Service Pricing in Highland
Reflectix attic retrofit pricing in Highland typically runs from $1.50 to $3.00 per square foot of installed radiant barrier, depending on attic configuration, access, and whether air sealing is included. Crawl space applications run slightly higher per square foot due to working conditions. Duct wrap jobs are usually quoted per linear foot, and baffle installation is priced per baffle.
What drives cost more than anything in Highland is the condition of the existing attic. An open, clean attic with good access is a fast job. A 1960s ranch with settled original insulation, old wiring, and cramped truss spacing takes longer, and that’s reflected in the estimate. Our free estimates include a full attic inspection, Radiant barrier condition assessment, air sealing evaluation, and a written quote with the recommended product and method.

FAQs – Reflectix Insulation in Highland
Yes, it does, when it’s installed correctly. Radiant barrier works by reflecting radiant heat away from the attic floor and ductwork, which is exactly where Highland’s summer heat load comes from. A properly installed Reflectix radiant barrier can drop attic temperatures by 10 to 20°F during peak summer conditions, which reduces the heat that migrates into your living space and the work your AC has to do. The key in Highland is installation quality – gaps, sags, and missing seal at the edges kill the performance. Call (855) 382-3451 and we can assess your attic to tell you if radiant barrier makes sense for your home.
The foil itself holds up fine, but the installation often doesn’t. Reflective foil doesn’t absorb smoke the way fiber insulation does, which is good. The problem is that perforated Reflectix and unsealed seams let smoke draft through gaps, and ash buildup on the reflective surface reduces performance even if the foil itself is intact. Highland homes need radiant barriers that are both reflective and tightly sealed – that’s the dual requirement our installs are built around. If smoke got into your house during the last fire season, call us. We can tell you where it came in and what sealing it properly involves.
We can, but whether Reflectix is the right product depends on your crawl space conditions. Reflectix Reflective Bubble Insulation works well in crawl spaces when it’s integrated with a proper vapor barrier and installed with the right orientation. Installed without vapor barrier integration, it can trap moisture against the foil and promote mold, especially in Highland’s winter rain cycles. We stock Reflectix for crawl space work and we’ll tell you honestly whether it’s the right material for your foundation or whether a different approach would be more durable.
That depends on what we find when we inspect it, and we’ll give you a straight answer. If the panels are sagging but the foil surface is still shiny and intact, re-securing with reinforced fasteners is usually enough. If the foil is delaminated, dull, or heavily coated with ash that won’t clean off, replacement with upgraded fastening and sealing is the better long-term call – Highland’s attic temperatures will continue to punish degraded material. The inspection is free, and you’ll get our honest recommendation on repair versus replacement.
Yes, and in Highland we strongly recommend it. Air sealing is the part of the job that closes the gaps smoke uses to get into your home – penetrations around wiring, plumbing vents, recessed lights, attic hatches, and the building perimeter. Reflectix is the reflective layer; air sealing is what keeps Santa Ana smoke and its odor out of your living space. We combine the two on most radiant barrier retrofits we do in Highland.
