Reflectix Insulation in Boerne, TX | Topside Attic Insulation Boerne
Reflectix radiant barrier service in Boerne typically runs $1,800-$3,400 for full attic installation, with most repairs and top-ups completed same-day. We’re independent Reflectix specialists - not manufacturer-authorized - which means we source OEM-compatible material or equivalently rated foil-faced product based on what your attic actually needs, not what a brand catalog says. In Boerne’s Hill Country conditions, that independence matters: we’ve seen too many metal-roof homes where face-down radiant barrier foil turned the attic into a convection oven, and too many post-Uri freeze events where unpaired Reflectix let condensation drip onto ceiling drywall. Call (830) 529-7780 for a written estimate before any work starts.
Why Boerne Residents Choose Us for Reflectix Service
We’ve been providing Boerne Attic Insulation since the first master-planned waves hit the I-10 corridor. That means we’ve tracked Reflectix products through real Hill Country summers and real Hill Country freezes - not lab conditions in Dallas or Houston. Wes Okafor, who leads our crew, learned the trade at Olive-Harvey College’s building technology program and has spent eighteen years figuring out why insulation performs or fails in specific building envelopes. He keeps a well-used ACCA Manual J on his truck for the conversations that happen at kitchen tables when a homeowner wants to understand why R-38 in an attic floor behaves differently than R-38 in a cathedral ceiling.
Our approach is straightforward. We run a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - before we touch any insulation. We air-seal top plates, can lights, and penetrations first. Then we install or repair Reflectix. “Seal the envelope first. Then fill it.” Every job closes with a Documented Photo Record and, on applicable work, before-and-after blower-door numbers in writing. Under Haven Standard, you get a flat price, written scope, and written warranty before anyone lifts a tool. No exceptions.
Common Reflectix Insulation Problems We Solve in Boerne

- Radiant barrier foil installed face-down against metal roofing. Boerne’s Hill Country-style homes often feature metal roofs that supercharge radiant heat gain. When Reflectix foil faces the roof deck instead of the attic air space, the aluminum conducts heat downward rather than reflecting it. We’ve measured attic temperatures exceeding 150°F in these conditions, and the fix is removal, proper orientation, and verification of the air gap.
- Bubble-pack Reflectix compressed behind electrical boxes or HVAC platforms. The BP48010 and SPW16025 products rely on trapped air for their R-value. In Boerne’s dry climate, compression is permanent - the bubbles don’t rebound. Once crushed behind a platform or junction box, performance drops to near zero, and the homeowner is left with shiny foil that does almost nothing.
- Edge stapling that tears the metallized layer. Boerne’s elevation drives larger diurnal temperature swings than San Antonio, causing expansion and contraction at staple points. Torn foil exposes the plastic core, and Hill Country dust coats the reflective surface, halving emissivity within a few seasons. We see this consistently in attics where a handyman or builder did quick work without understanding the product.
- Installed as sole insulation over existing blown fiberglass. After Winter Storm Uri in February 2021, we inspected multiple Boerne homes where Reflectix radiant barrier was the only attic upgrade. During hard freezes, the foil became a cold surface on the warm side of the assembly. Condensation formed on metal roof decks, wetting the existing fiberglass below and creating mold conditions that didn’t exist before the “upgrade.”
- Dust-fouled foil in ventilated attics. Boerne’s dry, windy conditions pull fine caliche dust through soffit vents. Over time, this film darkens Reflectix surfaces and degrades reflectivity. The product isn’t failed - it’s just dirty - but cleaning metallized film without damaging it requires specific technique, and sometimes replacement is more cost-effective.
Reflectix Service in Boerne: What Local Conditions Mean for Your Equipment
Boerne sits at roughly 1,400 feet on the Edwards Plateau escarpment. That elevation matters for Reflectix performance in a way it doesn’t in San Antonio’s lower basin. The day-night temperature swing up here is measurably wider. Attic surfaces that hit 140°F at 4 p.m. can drop to 50°F by 6 a.m. during a spring cold front. Reflectix radiant barrier alone - without proper ventilation and a warm-side air barrier - becomes a condensation surface during those hard freeze events. We’ve documented this in homes near the Cibolo Nature Center and in the Esperanza subdivision: clean, properly installed Reflectix that performed fine through summer, then produced dripping water onto ceiling insulation during a February freeze. The solution isn’t removing the Reflectix. It’s pairing it correctly - sealing air leaks so warm, moist interior air can’t reach the cold foil, ensuring adequate ridge and soffit ventilation to flush attic humidity, and in some cases adding a thin layer of spray foam or blown fiberglass as a thermal buffer. This is the diagnostic work Wes Okafor refers to when he says insulation is where the real building science happens. Generic installation guides written for Florida or Arizona don’t account for Boerne’s dual-extreme climate, and we’ve corrected enough of those installs to know the difference.
Reflectix Models & Products We Service in Boerne

We work with the full Reflectix residential line and stock the most common sizes for Boerne service area jobs. The Reflectix sales & service we provide covers BP48010 (48″ x 10′ double-reflective bubble pack), BP24025 (24″ x 25′ double-reflective bubble pack), RB48125 (48″ x 125′ radiant barrier roll), and SPW16025 (16″ x 25′ staple tab reflective insulation). We carry Reflectix-brand rolls and foil tape for homeowners who want to match existing material or maintain a specific product spec. When brand matching isn’t a priority, we source equivalently rated foil-faced radiant barriers from Owens Corning, Johns Manville, and other manufacturers in our supplier network - same performance in Boerne’s heat, sometimes better availability. Our repair-versus-replace stance is honest: if your existing Reflectix has a clean, uncompressed air gap and intact foil, we’ll top up and repair. If it’s crushed, dusty, or improperly oriented, we remove it and often pair new radiant barrier with blown-in insulation for total R-value. Most Boerne stock is on our truck or available next-day from San Antonio suppliers.
Reflectix Service Pricing in Boerne
Most Reflectix radiant barrier installations in Boerne run between $1,800 and $3,400 for a typical 2,000-2,800 square foot attic. Repairs and top-ups where existing material is salvageable typically fall between $650 and $1,400. What drives the cost: attic accessibility (steep pitches and tight scuttles add labor), whether air sealing is needed before radiant barrier goes in, and whether we’re pairing Reflectix with blown-in insulation for total R-value. Every estimate includes the blower-door test, written scope, and Documented Photo Record - not extras, baseline. We don’t start work without a written price. Haven Standard Clause 1.

FAQs - Reflectix Insulation in Boerne
Yes, but only when installed with the reflective face toward the attic air space and a verified air gap of at least 3/4 inch. On Boerne’s common metal-roof homes, face-down installation or contact with the roof deck turns the foil into a heat conductor rather than a reflector, and we’ve measured attic temperatures 20-30°F higher than properly oriented installs. We verify orientation with a simple gap check and infrared thermometer before signing off. Call (830) 529-7780 if you’re unsure about your existing install.
No. Reflectix radiant barrier is not insulation in the thermal-resistance sense; it reduces radiant heat transfer but provides minimal R-value on its own. After Uri, Texas amended energy code enforcement in many jurisdictions, and Kendall County inspectors now look for total assembly R-value, not just radiant barrier presence. We pair Reflectix with blown fiberglass or cellulose to achieve R-38 or R-49 in the attic floor, depending on your home’s code year. For a code-compliant scope and written price, call (830) 529-7780.
Caliche dust pulled through soffit vents is the culprit. Boerne’s dry, windy conditions deposit fine particulate on reflective surfaces, and once the emissivity drops, the foil becomes less effective at rejecting radiant heat. Darkened foil can lose 30-50% of its original reflectivity. Cleaning is sometimes possible with low-pressure air, but often replacement is more cost-effective, especially if the product is already five-plus years old. We document the condition with photos before recommending either path.
Three measures: air-seal the attic floor so warm, moist interior air can’t reach the cold foil; ensure adequate ridge-and-soffit ventilation to flush humidity; and in freeze-prone assemblies, add a thermal buffer layer of blown insulation between the living space and the radiant barrier. Boerne’s 1,400-foot elevation creates wider temperature swings than lower Hill Country areas, making the air-sealing step non-negotiable. We’ve corrected multiple post-Uri condensation failures where this sequence was skipped.
Yes, and this is the most common Reflectix job we do in Boerne’s master-planned subdivisions. Most 2000s-2020s production homes here were built to minimum code with blown fiberglass that has settled below spec. We air-seal first, then install Reflectix RB48125 across the roof deck with verified air gap, and top up the existing fiberglass to R-38. In a 2016 Esperanza home, this exact sequence dropped August cooling costs by roughly 22% and reduced peak attic temperature from 155°F to under 130°F.
