Why New Braunfels Homeowners Choose Reflectix Insulation
We provide Reflectix in New Braunfels, specializing in radiant barrier repair, replacement, and new installation on roof decks and attic assemblies. Our crews work with Reflectix foil products almost daily in Hill Country attics, and we install them with documented air gaps and proper seam sealing so the reflective facing actually performs instead of bubbling or turning gray by year three. Call (830) 243-6352 for a written price before any work starts.
Reflectix radiant barriers show up in a lot of New Braunfels homes for good reason. The foil-based products block radiant heat transfer across attic air spaces, which matters here more than in most Texas markets. New Braunfels sits at the Balcones Escarpment where summer attic temperatures routinely hit 140°F, and that radiant load pours through the ceiling assembly if there’s nothing to stop it. We’ve worked neighborhoods all over the growth corridor, from Veramendi to Hunter’s Crossing to Elm Creek, and the pattern is consistent: builders installed code-minimum blown fiberglass to hit price points, leaving the radiant heat path wide open.
We’re not affiliated with or authorized by Reflectix. We’re an independent crew that learned this product line through hands-on installs and callbacks across Comal County, not through any dealer program. That independence means we can tell you honestly when Reflectix is the right fix and when your attic needs something else first.
Why Trust Topside Attic Insulation New Braunfels for Your Reflectix Insulation?
Wes Okafor, who leads our crew, picked up his trade fundamentals at Dawson Technical Institute on Chicago’s South Side before logging nearly two decades sealing attics and air-bypasses across Central Texas. He and our technicians have worked jobs off the River Road corridor near the Guadalupe, where stack-effect air leakage in older slab homes tends to run higher than homeowners expect. That background matters for Reflectix work because a radiant barrier is only as good as the air gap behind it and the sealing around it, and Wes runs a blower-door test - a pressurization diagnostic that measures how many cubic feet of conditioned air a house leaks per minute - before and after every install so the customer leaves with printed pre- and post-job numbers rather than a verbal estimate of improvement.
We stock genuine Reflectix BP48010 and BP48025 rolls, BP24010 perforated barrier, and FT210 foil tape on our New Braunfels trucks. When we repair a failed radiant barrier, we use the same reflective facing and adhesive chemistry that was originally installed, so seams match and thermal performance stays consistent across the deck. We also carry aftermarket standoff clips and baffles for the air gaps that factory installs often skip.
Our 365-Day Done Right Promise applies to every Reflectix job. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
Common Reflectix Insulation Problems We Fix in New Braunfels
- Foil delamination and bubbling on roof-deck installs. This is the failure we see most often in New Braunfels’ west-facing attics. When Reflectix is laid tight against hot sheathing with no air gap, the adhesive backing softens in 140°F+ temperatures and the reflective facing bubbles away from the substrate. The foil still looks shiny from below, but it’s no longer making thermal contact where it counts. We remove the bubbled sections, install proper standoff baffles, and re-staple new Reflectix perforated roll with a minimum ¾-inch air gap so convection can carry heat away.
- Staples and seams pulling apart after two or three summer cycles. The thermal expansion in a New Braunfels attic is brutal: 40°F winter mornings to 140°F August afternoons, repeated hundreds of times. Factory staples loosen. FT210 tape seams creep. Gaps open at the ridge and eaves. Once the foil surface is interrupted, radiant heat slides through the openings and the barrier’s effective performance drops by half or more. We re-fasten with ring-shank foil fasteners and re-tape with genuine FT210, or we replace the whole run if the damage is too scattered.
- Dust and blown-in insulation settling on the reflective face. This one sneaks up on homeowners. Reflectix works by reflecting radiant energy, not by absorbing it. When blown fiberglass or cellulose drifts onto the foil surface during a top-up install, or when attic dust accumulates over years, the shiny surface turns dull gray. At that point it’s radiating heat into the attic air instead of reflecting it back toward the roof deck. We see this constantly in the post-2010 subdivisions along FM 306 and FM 1101, where speed-cut insulation crews left fiberglass thin over exterior walls and thick over the foil barrier. We clean the facing or replace the barrier, then install proper baffles to keep insulation from contacting the foil.
- Trapped moisture behind vapor-tight foil layers. Reflectix is not a vapor barrier in its perforated form, but homeowners and some installers confuse the two. When non-perforated foil is installed on knee walls or in crawl spaces without drying paths, humid Gulf air from the Guadalupe and Comal River corridors condenses against the cool side. We’ve found rusted fasteners, moldy sheathing, and musty attic air in homes near the river where the wrong product went in the wrong place. We swap to perforated BP24010 where vapor needs to pass, or we add mechanical ventilation if the assembly demands a sealed facing.
- Reflectix installed over unsealed air leaks. This isn’t a product failure; it’s a sequence failure. We tore out a foil radiant barrier on a 1990s New Braunfels home near Gruene after the homeowner kept seeing 88°F upstairs despite the AC running nonstop; the Reflectix facing had bubbled and delaminated across the west roof deck with no air gap. We removed the failed foil, stapled new Reflectix perforated roll with proper standoff, and married it to a blown-in fiberglass top-up, and the upstairs finally dropped into the mid-70s. The foil didn’t fail because it was bad product. It failed because it was installed without air sealing first and without the air gap the manufacturer specifies.
Before
AfterReflectix Parts & Our Repair-vs-Replace Approach
We use genuine Reflectix-brand foil rolls and Reflectix FT210 tape for repairs and new installs so the reflective facing and adhesive match what’s already on the decking. Our New Braunfels trucks also carry aftermarket foil fasteners and baffles where the factory staples have failed. If a barrier is bubbling or defaced across more than about a third of the roof deck, we recommend full replacement rather than patching because radiant performance is only as good as the uninterrupted foil surface. A patchwork of shiny and dull reflects unevenly; heat finds the gaps.
We don’t upsell replacement when repair will hold. We also don’t patch a deck that’s going to fail again in two summers. You’ll get a written scope either way, with photos of the damage and a flat price before anyone lifts a tool. Call (830) 243-6352 and we’ll read your situation with you.
Our Reflectix Service Process - Step by Step
- 1
Diagnosis with blower-door and visual inspection. We pressurize the house to measure CFM50 leakage, then climb to photograph the Reflectix condition, air gap, staple spacing, and any dust or insulation contact. You get the photos and the blower-door number before we quote.
- 2
Written scope and price. Under Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool. No exceptions.
- 3
Air sealing first, then barrier work. We seal top plates, can lights, and penetrations before touching the Reflectix. Installing radiant barrier over an unsealed attic floor is something we simply don’t do.
- 4
Repair or replace with proper air gaps. We use BP48010 or BP48025 for large decks, BP24010 perforated where vapor management matters, and FT210 tape on every seam. Standoff clips maintain the air gap the manufacturer requires.
- 5
Post-install blower-door test and photo record. We run the house under pressure again, compare to the pre-job number, and print both readings for your file. The Documented Photo Record goes to you by text or email before we leave.
- 6
365-Day Done Right Promise activation. Written warranty, filed by address. If it’s not done right, we make it right.
Reflectix Products We Service & Install in New Braunfels
We work with the full residential Reflectix line: Double Reflective Insulation Roll in 48-inch widths, both the 10-foot BP48010 and 25-foot BP48025; Radiant Barrier Perforated Roll BP24010 for assemblies that need vapor permeability; and FT210 Reflective Foil Tape for seam sealing and repair. We stock these on our New Braunfels trucks for same-day repair work. For larger replacement jobs, we pull fresh rolls from our supplier in San Antonio with next-morning availability.
We also handle Attic Insulation services like removal when old Reflectix has to come out before new product goes in, and we marry radiant barrier work to blown-in fiberglass or spray foam top-ups where the thermal assembly needs more than just radiant control.
We Also Service These Brands
We’re not a single-brand shop. Our crews install and repair Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber products. That range matters because some New Braunfels attics need a hybrid approach: Reflectix on the roof deck, blown fiberglass on the floor, spray foam at the rim joist. We can quote the assembly that actually fits your house, not the one product line we happen to push.
FAQs - Reflectix Insulation Service in New Braunfels
Is Topside Attic Insulation New Braunfels authorized by Reflectix?
No. We are an independent Reflectix service provider with no manufacturer authorization or affiliation. We learned this product through field installs and callbacks across Comal County, not through a dealer program. Our independence lets us recommend honestly when Reflectix fits and when another approach works better.
Will Reflectix alone keep my New Braunfels attic cool in summer?
No. Reflectix blocks radiant heat transfer across an air space, but it does not insulate against conductive heat flow the way fiberglass or foam does. In a New Braunfels attic hitting 140°F, you need both: radiant barrier on the roof deck to stop the radiant load, and adequate R-value on the attic floor to slow conduction through the ceiling. We see the best results when Reflectix is paired with air sealing and blown-in fiberglass or cellulose. Call (830) 243-6352 and we’ll measure your attic to spec the right assembly.
Why did the Reflectix on my roof deck turn gray and stop reflecting?
Dust accumulation and contact with blown-in insulation have covered the reflective aluminum facing. Reflectix only works when the surface stays shiny; a gray or dusty foil becomes a radiant absorber instead of a reflector. This is common in New Braunfels attics where insulation was added after the barrier went in, or where baffles were never installed to keep the two separated. We clean or replace the facing and add proper standoffs so it stays reflective.
Can you install Reflectix over spray foam or existing fiberglass in a New Braunfels attic?
Reflectix installs over open-cell spray foam only if there’s an air gap between the foil and the foam surface; laid tight against foam, it does nothing. Over existing fiberglass on the attic floor, we install Reflectix on the roof deck above, not on top of the fiberglass, because compressing fiberglass reduces its R-value and the foil needs an exposed air space to function. Every assembly we quote includes the air-gap detail in writing.
Does Reflectix install require any special tape or fasteners?
Yes. We use Reflectix FT210 tape on every seam because standard duct tape adhesive fails in attic heat. For fasteners, we use ring-shank foil staples or aftermarket standoff clips that maintain the required air gap. The factory staples that come in some builder-grade kits often pull loose after two or three New Braunfels summers.
Is a Reflectix radiant barrier worth it on a metal roof in the Hill Country?
Yes, often more so than on shingle. Metal roofs radiate heat downward aggressively in summer, and the thermal cycling is sharper than with asphalt. A properly installed Reflectix barrier with adequate air gap can drop radiant heat transfer through the ceiling assembly by 40% or more. We’ve measured the difference on blower-door and infrared jobs across the I-35 corridor. The key is the air gap and the sealing around it; without both, you’re just stapling shiny paper to hot metal. Call (830) 243-6352 for a free estimate on your specific roof assembly.
How much does Reflectix insulation cost in New Braunfels?
Most Reflectix radiant barrier installations in a typical New Braunfels home run between $1,800 and $3,400 for a complete roof-deck application, depending on attic square footage, accessibility, and whether we’re removing failed existing barrier first. Repair work on localized delamination or seam failure typically runs $400 to $900. We give a flat written price before any work starts, and we offer a Free Second Opinion on any competing written estimate. Call (830) 243-6352 for an exact quote on your attic - estimates are free.
