Why New Braunfels Residents Choose Us for Reflectix Service
We’ve worked with Reflectix sales & service in New Braunfels attics since the early 2000s. That matters because Reflectix foil behaves differently here than in Dallas or Houston. The Hill Country’s combination of 140°F attic peaks and hard freezes creates expansion cycles that stress seams and adhesives in ways stable climates don’t.
Wes Okafor, our owner, grew up on the South Side of Chicago and trained at Dawson Technical Institute before logging nearly two decades sealing attics across Central Texas. He and our crew have worked neighborhoods all over New Braunfels, including 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. 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. He keeps a copy of every test report filed by address.
We stock genuine Reflectix foil, tape, and fasteners locally for fast turnaround. No waiting on Dallas shipments. No generic substitutions that void emissivity ratings.
Common Reflectix Insulation Problems We Solve in New Braunfels

- Foil delamination from extreme heat cycling. In New Braunfels’s 100°F+ attic heat, the adhesive bonding Reflectix foil to its bubble core dries out and separates. We see this most often in 5-to-15-year-old tract homes in Veramendi and Hunter’s Crossing, where builders rushed insulation to hit price points during the construction boom.
- Surface dust accumulation killing reflectivity. Blown fiberglass particles and Gulf humidity settle on Reflectix foil, dropping emissivity from 0.05 to near 0.5. In homes near the Comal River corridor, where ambient humidity runs measurably higher, this performance cut happens faster than inland.
- Tape seam failure from thermal shock. The acrylic adhesive on Reflectix foil tape releases in attics that swing from 110°F summer afternoons to 20°F winter nights. After February 2021’s Uri freeze, we replaced failed tape in dozens of New Braunfels attics where seams had opened wide.
- Moisture trapping against roof decking. When Reflectix is stapled directly against decking without a vented air gap, condensation from humid Guadalupe River corridor air gets trapped. We’ve found deck rot in Elm Creek homes where this exact installation error was made during the 2012-2018 building rush.
- Thin or missing coverage over exterior walls and can lights. Along FM 306 and FM 1101, crews racing to keep up with New Braunfels’s growth often installed Reflectix to correct depth at the hatch but left dramatic thin spots over thermal bypasses. The foil was present. It just wasn’t where the heat was coming through.
Before
AfterReflectix Service in New Braunfels: What Local Conditions Mean for Your Equipment
New Braunfels’s position at the Balcones Escarpment creates a thermal seesaw found almost nowhere else in Texas. Attics bake above 140°F in July and August, then drop below freezing during Arctic outbreaks like the February 2021 Uri event. That 120-degree swing causes Reflectix foil to expand and contract more aggressively than in stable climates, accelerating seam failure, staple pull-out, and adhesive degradation.
In a 2012 Veramendi home, our tech found Reflectix radiant barrier with severe foil delamination - sheets were peeling off the rafters and lying flat on the blown fiberglass. We removed the failed material, re-stapled new Reflectix foil over the roof deck with a 3/4-inch vented air gap, and sealed all seams with Reflectix foil tape. The homeowner reported a 12°F drop in upstairs room temperature the following July. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
This dual-season stress is why we never install Reflectix without checking for adequate attic ventilation first. In New Braunfels, a radiant barrier without airflow becomes a moisture trap. A radiant barrier with airflow becomes a legitimate thermal upgrade.
Reflectix Models & Products We Service in New Braunfels

We work with the full Reflectix residential line: Double Reflective Insulation Roll in both 48-inch and 24-inch widths, Reflective Foil Tape (2-inch by 30-foot), and Radiant Barrier Roof Decking in 4-foot by 8-foot panels. For repairs, we use genuine Reflectix foil, tape, and fasteners to ensure emissivity ratings hold up at 0.05. Generic substitutes often test at 0.15 or higher, which cuts performance by two-thirds.
For full attic retrofits, we may recommend upgrading to a perforated radiant barrier or our Spray Foam Insulation in New Braunfels if Reflectix alone can’t address air leakage and R-value gaps. We stock common Reflectix sizes locally, so most New Braunfels repairs start within 48 hours of the estimate.

FAQs - Reflectix Insulation in New Braunfels
Yes, when installed with a vented air gap and clean foil surface. Reflectix blocks up to 97% of radiant heat transfer in a properly vented New Braunfels attic. It fails when dust accumulates, seams open, or it’s pressed directly against decking with no airflow. Call (830) 243-6352 and we’ll test your existing foil’s emissivity.
Every 10-15 years in New Braunfels’s climate, sooner if you see delamination or dust buildup. The Balcones Escarpment’s extreme thermal cycling accelerates adhesive fatigue compared to milder markets. We inspect and document condition during every estimate.
Reflectix radiant barrier installs to the underside of roof rafters or decking, not on top of floor insulation. If your blown fiberglass is thin or uneven - common in FM 306 and FM 1101 subdivisions where crews rushed - we may recommend New Braunfels Attic Insulation to add depth before or alongside the radiant barrier install.
Use genuine Reflectix Reflective Foil Tape, not duct tape or generic foil tape. Clean the surface first, press firmly, and allow adhesive to set before attic heat cycles begin. In New Braunfels’s humidity, we also check that attic ventilation is adequate so tape doesn’t release from trapped moisture.
Reflectix alone does not provide meaningful freeze protection. It blocks radiant heat, not conductive heat loss. For freeze protection around plumbing penetrations - critical after Uri - we recommend combining air sealing with proper R-value insulation, not relying on radiant barrier. Call (830) 243-6352 for a written assessment of your specific freeze-risk areas.
