Reflectix Insulation in Cibolo, TX | Topside Attic Insulation Schertz
Reflectix radiant barrier service in Cibolo typically runs $1,800-$3,400 for a full attic retrofit, and most jobs we quote include air sealing and Cibolo Attic Insulation because foil alone won’t pass Texas code here. We’re an independent crew, not authorized by Reflectix, but we handle its products weekly in Cibolo’s post-2000 subdivisions where attic temps push past 150°F. Call (830) 402-5240 for a written estimate before any work starts.
Why Cibolo Residents Choose Us for Reflectix Service
We’ve been working the Schertz corridor long enough to know what happens when you staple Reflectix to a roof deck without an air gap in a Cibolo attic. Wes Okafor, our owner, picked up building science fundamentals at Richard J. Daley College in Chicago and spent the next two decades in attics before bringing that sequencing discipline to Guadalupe County. His crew has done jobs in The Crossvine and off FM 1518 where summer attic temps hit 140°F before we even unload the truck.
We carry genuine Reflectix BP48010 rolls and ST16025 staple-tab product on our trucks, but we also stock the aftermarket air-sealing foams and blown fiberglass that Cibolo’s production homes actually need. Every job starts with a blower-door test, ends with a documented photo record, and comes with before-and-after pressurization numbers when air sealing is part of the scope. That’s Haven Standard, and we’ve operated under it since 2016.

Common Reflectix Insulation Problems We Solve in Cibolo
- No air gap behind rafter-stapled Reflectix. In Cibolo attics hitting 150°F+, foil pressed tight to roof decking or rafters conducts heat directly into the framing instead of reflecting it. The attic gets hotter, not cooler. We see this constantly in 2005-2015 production homes where the original installer treated Reflectix like wallpaper.
- Non-perforated rolls trapping moisture in hot-humid assemblies. Cibolo sits in IECC Climate Zone 2. Non-perforated Reflectix in 2×4 wall cavities or against roof sheathing creates a vapor barrier on the wrong side of the assembly. We’ve pulled moldy sheathing in The Crossvine where trapped summer humidity had been condensing against foil for years.
- Dust accumulation killing reflectivity. Cibolo’s caliche soil and ongoing construction dust settles on exposed attic foil and drops emissivity from ~0.05 to near 0.5 within a few years. A reflective surface that can’t reflect is just expensive plastic. We evaluate whether cleaning and re-stapling makes sense or if the homeowner’s money is better spent on air sealing and additional blown insulation.
- Foil-only installations failing code and performance. Texas still requires R-30+ in attics. Reflectix radiant barrier contributes R-1 to R-3 at best. We’ve inspected Cibolo homes where a previous contractor sold Reflectix as “insulation replacement,” leaving the homeowner with 100°F+ indoor temps during August and a failed resale inspection.
- Unsealed top plates bypassing any radiant barrier benefit. Volume builders in Cibolo’s boom years blew R-30 fiberglass over unsealed attic floors. Conditioned air escapes through partition wall gaps at the top plates, carrying moisture and wasting energy regardless of how shiny the roof foil is. We seal first, then insulate, then add radiant barrier if the assembly supports it.
Reflectix Service in Cibolo: What Local Conditions Mean for Your Equipment
Cibolo’s entire housing stock was built in a narrow post-2000 window by the same national builders, so Reflectix radiant barrier installs here are almost always retrofits into 2×4-framed, R-13-wall tract homes in The Crossvine and similar master-planned subdivisions - not the custom-home foil applications you’d see in older San Antonio neighborhoods. This matters because retrofitting Reflectix into a 2×4 wall cavity with existing R-13 fiberglass leaves almost no room for an air gap, and without that gap the foil becomes a heat conductor, not a heat reflector. In attic applications, these same homes typically have 2×6 or scissor-truss rafter bays that can accommodate a proper radiant barrier installation, but only after the unsealed top plates and can-light penetrations are addressed. The February 2021 Winter Storm Uri exposed how poorly these production homes perform in cold snaps too, meaning Cibolo homeowners need envelope solutions that work in both directions - not just summer heat reflection. We sequence accordingly: blower-door test, air sealing, then evaluate whether Reflectix belongs in the assembly at all.
Reflectix Models & Products We Service in Cibolo
We work with the Reflectix product lines that actually show up in Cibolo attics: Reflectix sales & service covers the BP48010 Double Reflective Insulation Roll (48 in. x 10 ft., 5/16 in. bubble pack), the ST16025 Staple Tab Reflective Insulation (16 in. x 25 ft.) for rafter-bay installation, and the R-21 Radiant Barrier Roof Deck / Attic Rafter Application. We stock both perforated and non-perforated Double Reflective Bubble Pack rolls, but in Cibolo’s hot-humid climate we default to perforated unless the assembly specifically calls for a vapor barrier on the exterior side.
Our stance on parts: genuine Reflectix brand rolls and tapes for radiant barrier applications, quality Cibolo Spray Foam Insulation and blown insulation for the bulk thermal envelope. We don’t pretend Reflectix is a substitute for R-30+ attic insulation. If your existing foil is salvageable, we’ll clean it, re-staple it with proper air gap, and spend your budget where it actually moves the needle on the blower-door test.
Reflectix Service Pricing in Cibolo
Most Reflectix radiant barrier retrofits in Cibolo run between $1,800 and $3,400, depending on attic square footage, whether we’re removing failed existing foil, and how much air sealing the top plates and penetrations need. A typical scope breaks down like this:
- Reflectix radiant barrier removal and disposal (if failed): $400-$650
- Attic air sealing - top plates, can lights, penetrations: $800-$1,400
- Perforated Reflectix reinstallation with proper air gap: $600-$1,100
- Blown fiberglass top-up to R-38 (if needed): $1,200-$2,200

FAQs - Reflectix Insulation in Cibolo
No. Reflectix radiant barrier contributes R-1 to R-3 effective thermal resistance at best. Texas code requires R-30 minimum in Cibolo attics, and Guadalupe County inspectors enforce it. Foil-only installations fail inspection and leave you with 100°F+ indoor temps in August. We pair Reflectix with blown fiberglass or cellulose to hit code and performance targets. Call (830) 402-5240 for a written scope that shows exactly how we get there.
Three reasons we see weekly in Cibolo: dust coating the reflective surface (caliche and construction dust drops emissivity by half), no air gap between foil and roof deck (turns reflector into conductor), or unsealed attic floor bypasses letting conditioned air escape regardless of roof temperature. In The Crossvine, we regularly find all three in the same 2010-era home. The fix is diagnostic, not cosmetic - we blower-door test first, then prescribe.
We generally don’t recommend it. Cibolo’s 2×4 exterior walls have 3.5 inches of cavity depth already occupied by R-13 or R-15 fiberglass. Adding Reflectix leaves no air gap, and non-perforated rolls trap moisture against sheathing in our hot-humid climate. If wall performance is the goal, we typically recommend dense-pack cellulose or injection foam after air sealing, with Reflectix reserved for attic radiant barrier applications where rafter bays allow proper installation geometry.
$1,800-$3,400 for most Cibolo homes, with the final number driven by attic square footage, whether failed foil needs removal, and how much air sealing the unsealed top plates require. Every quote includes a blower-door test, written scope, and documented photo record. Call (830) 402-5240 - estimates are free, and we deliver a written price before any work starts.
It depends on what you already have and what’s failing. Many 2008 Cibolo homes have settled R-30 fiberglass, unsealed top plates, and either no radiant barrier or a failed installation. Reflectix as a supplement - after air sealing and blown insulation - can drop attic temps 30°F or more. As a standalone fix, it’s not worth the staple holes. We inspect first, show you the blower-door numbers, and let the data drive the decision.
