Reflectix Insulation in Bloomington, CA | Thermal Insulation Co
We install, repair, and replace Reflectix radiant barrier and reflective insulation across Bloomington’s 92316 ZIP. The thing that makes our Reflectix work different here is simple: most of the homes in Bloomington were built between the 1950s and 1970s, and their attics hit 150°F or higher every July. That heat exposes installation mistakes that a coastal contractor might never see. If you need Reflectix service in Bloomington, call Thermal Insulation Co at (855) 382-3451 for a free estimate.

Why Bloomington Residents Choose Us for Reflectix Service
Reflectix is a specific product line, not a generic foil. We know the difference between the Double Reflective Insulation Roll with its bubble-pack core and the single-side Reflective Foil Insulation meant for different applications. We also know what happens when either one is stapled directly to roof sheathing in a Bloomington summer. Ruben Castellano, owner of Thermal Insulation Co, learned building science at East Los Angeles College before spending nearly two decades diagnosing why homes in the Inland Empire stay hot no matter what previous contractors tried. That experience includes Reflectix service in Fontana and surrounding communities. That background matters when a homeowner calls us about foil sagging off rafters in a 1960s tract home off Cactus Avenue.
We carry Reflectix-manufactured rolls and tape for repairs because continuity matters. A patch job with off-brand foil creates gaps and uneven performance. But we won’t pretend every damaged radiant barrier is worth saving. When the foil surface is mostly shot or the attic ventilation was never corrected, we’ll say so plainly. That’s the independent advantage: we’re a dedicated insulation contractor, not a Reflectix dealer pushing product.
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.
Common Reflectix Insulation Problems We Solve in Bloomington
These are the failure patterns we see over and over in Bloomington attics. Each one connects to something real about how this city’s homes were built and how hot they get.
- Staple tear-out and sagging along rafter bays. The thin foil expands and contracts with every 40-degree overnight-to-afternoon temperature swing, and standard staples pull right through. After a few summers, long sections hang loose. We see this constantly in 1950s and 1960s stucco tract homes with low-pitch attics.
- Foil delamination and bubbling on roof sheathing. When Reflectix is installed directly against hot sheathing without the required air gap, the adhesive layers break down. The bubble pack cells separate from the foil face, and the product loses nearly all its reflective performance. This is the single most common installation error in Bloomington attics.
- Dust and soot accumulation on the reflective surface. Older Bloomington homes often have soffit vents clogged by decades of blown-in insulation that drifted during HVAC retrofits. Once airflow stops, dust settles on the foil. A dirty reflective surface stops reflecting. Emissivity drops, and the barrier becomes just another layer of dirty plastic in the attic.
- Crushed or compressed bubble cells. Bloomington’s low-pitch attics invite storage, and homeowners put boxes and old window units right on top of the foil. The bubble cells collapse, the air gap inside the product disappears, and the R-value contribution drops to almost nothing. We’ve pulled flattened Reflectix out of attics that looked like it had been run over.
- Missing air gap behind the barrier. Reflectix radiant barrier only works when there’s dead air space on at least one side. In Bloomington tract homes where the foil was stapled tight to the sheathing in the 1980s or 1990s, there was never a gap to begin with. The foil has been doing nothing for decades except trapping heat against the roof deck.
Reflectix Service in Bloomington: What Local Conditions Mean for Your Equipment
Bloomington’s 92316 ZIP sits in a pocket of the Inland Empire where summer attic temperatures routinely exceed 150°F. Not estimate, not “feels like”: measured air temperature inside the attic space itself. That heat intensity combined with the housing vintage here, mostly 1950s through 1970s single-story stucco tract homes with original R-7 to R-11 insulation, creates a specific failure profile we rarely see in newer or coastal developments. The original blown-in insulation in these homes has settled and compressed over 50 or 60 years, and in many attics it has drifted into the soffit vents during HVAC and electrical retrofits. When we’re called to service Reflectix in Bloomington, our first step is never to add more foil. We’ve applied the same method during Reflectix repair in Rialto and other nearby cities. It’s a gap and ventilation check. We inspect whether the existing radiant barrier has the required air space behind it, whether the soffit vents are actually drawing air, and whether the foil surface is clean enough to reflect anything. Adding radiant barrier on top of an attic with no ventilation fixes nothing. Correcting the airflow first is what makes the Reflectix actually perform.

We work on the full residential Reflectix line. That includes the Double Reflective Insulation Roll with the bubble-pack core, the single-side Reflective Foil Insulation, the Perforated Radiant Barrier for vented attics, and the Attic Staple Kit hardware. For repairs and top-ups, we use Reflectix-manufactured rolls and foil tape so the product stays continuous. We stock standard widths locally, which means most Bloomington repair jobs can be completed same-week. If you’re unsure which Reflectix product is in your attic, we’ll identify it during the estimate. For broader context on the brand and our approach, see our Reflectix sales & service page.
Reflectix Service Pricing in Bloomington
What you’ll pay depends on three things: how much foil has failed, whether the attic ventilation needs correction, and whether you’re topping up old insulation at the same time. Repair work on a Bloomington attic where most of the foil is intact, meaning staple re-securing, seam taping, and vent clearing, typically runs $400 to $900. Full replacement of a failed radiant barrier in the same 800 to 1,200 square foot attic generally runs $1,500 to $3,200, with the higher end reflecting crushed bubble pack that has to be fully removed rather than covered over. Every quote includes the gap and ventilation assessment. Call (855) 382-3451 for an exact price on your Bloomington attic. Estimates are free.

FAQs – Reflectix Insulation in Bloomington
No. Reflectix radiant barrier is designed to be stapled to the underside of roof rafters or laid over attic floor joists with an air gap maintained between the foil and the surface below it. In Bloomington homes with settled original insulation, laying foil directly on top of the old blown-in material crushes the bubble cells and eliminates the air space the product needs to function. We first assess whether the existing insulation is even worth keeping. If it has compressed to R-7 or R-11 equivalent, topping it up before adding radiant barrier is usually the better order of operations. Call (855) 382-3451 and we’ll tell you what your attic actually needs.
The darkening is dust and soot accumulation on the reflective surface, and it happens when soffit vents clog and airflow stops. Bloomington’s older tract homes have soffit vents that fill with drifted blown-in insulation and decades of dust, especially after HVAC retrofits. Once the surface stops reflecting, the foil is doing nothing. We clear the vents, and if the foil surface has been degraded beyond a simple cleaning, we replace the affected runs with new perforated Reflectix barrier so airflow can pass through. Repairs typically take under a day once we’re in the attic.
Reflectix radiant barrier is not an R-value product in the traditional sense. The bubble pack roll carries an R-value of about 1.0 to 1.1 by itself, which is minimal. What it does is reflect radiant heat away from the attic floor, and in a Bloomington attic that’s hitting 150°F, that reflection matters far more than a small R-value addition. The key variable is the air gap. Without it, you get neither the R-value contribution nor the radiant reflection.
We base that call on two factors: how much of the foil surface remains intact and whether the attic ventilation has been corrected. If you have a few failed staple runs and some tape seams that have let go, repair is straightforward and cost-effective. If the foil has delaminated from the bubble pack, been crushed by storage, or the surface is so dirty it can’t be cleaned, replacement is the honest answer. In Bloomington attics where the foil was installed without a gap from the start, patching it buys nothing. We’ll show you the condition before we recommend either path.
Yes, but installation details matter more. Low-pitch attics in 1950s and 1960s Bloomington tract homes have less vertical clearance, which means the radiant barrier is closer to the roof deck and more exposed to direct heat. That makes the air gap non-negotiable. It also makes crushed bubble cells more likely, because homeowners use the limited headroom for storage and end up placing boxes directly on the foil. We install perforated barrier in vented low-pitch attics so warm air can pass through rather than getting trapped against the sheathing. Call (855) 382-3451 to have your specific attic assessed.
