Reflectix Insulation in New Braunfels, TX | Thistledown Insulation San Antonio
We provide independent Reflectix insulation service across New Braunfels, from downtown limestone cottages to the new subdivisions spreading toward Vintage Oaks. The thing that makes our Reflectix work here different is simple: we know how river humidity and west-facing Hill Country sun combine to undermine reflective insulation, and we account for that before we staple a single roll.

Why New Braunfels Residents Choose Us for Reflectix Service
We’re a Cedarwell-family company, and we’ve been installing and servicing Reflectix radiant barriers and reflective insulation since long before the current building boom reshaped this town. Neil Barron, our owner, learned the trade pulling batts and reading spec sheets at Los Angeles Trade-Technical College, and he walks every New Braunfels job quietly before quoting it. His habit of measuring twice carries through our whole crew. We show up in uniform, lay drop cloths from the front door to the attic hatch, and put shoe covers on before anyone steps off the entry mat. Every Reflectix job gets a written price before we start, and every job carries our 365-Day Done Right Promise. If something isn’t right, we come back and make it right. No debate.
When you call about Reflectix service in New Braunfels, a live person answers. Not a voicemail tree, not a next-business-day callback. That matters when you’ve got a west-facing bedroom hitting 80°F by late afternoon and a toddler who won’t nap.
Common Reflectix Insulation Problems We Solve in New Braunfels
- Stapled-too-tight sagging and tearing: New Braunfels attic humidity runs high most of the year, especially near the Guadalupe and Comal river valleys. When Reflectix is stapled too tightly across rafter bays, the foil can’t move with temperature swings and ends up sagging or tearing. Torn foil means radiant heat slips through the gap and lands directly on your insulation below. We re-staple with the right tension and replace damaged bays with fresh genuine Reflectix rolls.
- Open seams not taped with reflective tape: In older New Braunfels homes, we regularly find radiant barrier installations where the seams were overlapped but never taped. The result is a patchwork of hot and cool strips running across bedroom ceilings. We re-tape every seam with matching reflective seam tape so the barrier actually functions as a continuous sheet.
- Dust and blown-in fiberglass settling on the foil surface: Attics with poor ventilation, common in 1970s-era Oakwood Estates and Castle Ridge homes, let dust settle on the shiny surface of Reflectix. Reflectivity drops by more than half once the surface is coated. We vacuum the top layer where possible and address the ventilation issue so the barrier stays clean.
- Condensation on the foil underside in winter: When Reflectix is installed against a cold roof deck, the underside can collect condensation during New Braunfels cold snaps. That moisture drips onto stored items or drywall below. We check the installation configuration and add ventilation or baffles where the condensation risk is highest, especially in homes near the river where dew points stay elevated.
- Original R-11 fiberglass performing like R-4: New Braunfels crews have a name for it: Texas attic melt. Decades of 140°F attic heat compress and blacken older fiberglass batts, and any radiant barrier installed over them inherits the problem. We assess what’s underneath your Reflectix and recommend replacement where the base layer is too far gone.
Reflectix Service in New Braunfels: What Local Conditions Mean for Your Equipment
New Braunfels sits on the edge of the Comal and Guadalupe river valleys, and that geography creates a problem most crews offering our Spray Foam Insulation in New Braunfels and other products in drier Texas cities never see. West-facing attic walls here bake in afternoon sun while the roof deck stays cooler because river-driven humidity holds heat differently than the dry air you’ll find twenty minutes west. That combination produces attic conditions where a Reflectix radiant barrier can actually contribute to ductwork condensation. The shiny foil reflects heat away from the attic floor, which sounds great, but if your ductwork runs through the attic and the dew point is high, the temperature drop around those ducts can pull moisture out of the air. We check for this on every Reflectix installation in New Braunfels. We look at where your ducts run, how your ventilation is set up, and whether the barrier should be installed on the rafters or the attic floor before we recommend anything. A crew that only works San Antonio doesn’t think about river-driven humidity. We do.
Reflectix Models & Products We Service in New Braunfels
We install and service the Reflectix product lines most common in New Braunfels attics: Double Reflective Insulation (ST16025, BP24025), Radiant Barrier (RB48125), Reflective/Bubble/Bubble/Reflective (RBBR4096), and Foil/Bubble/Foil (BFU400). When we replace or add barrier, we use genuine Reflectix rolls and matching reflective seam tape. For adjacent framing repair or ventilation prep, we use quality local lumber and baffles from New Braunfels suppliers. If a section of your existing barrier is torn, compressed, or too heavily dusted to clean back to reflectivity, we’ll recommend replacing that bay rather than pretending a wipe-down will restore performance.
Thistledown Insulation San Antonio is an independent Reflectix service provider. We are not manufacturer-affiliated or authorized. That independence means we tell you what your attic actually needs, not what a brand rep wants us to push. For broader Reflectix sales & service, we apply the same standard across every job.
Reflectix Service Pricing in New Braunfels
What you’ll pay depends on attic size, ceiling height, rafter spacing, and the condition of any existing insulation. A small single-story attic with straightforward access costs less than a two-story with a tight scuttle hole and trusses that make stapling slow work. We also factor in whether we’re re-taping existing seams, replacing damaged bays, or starting fresh with new Reflectix rolls. You’ll get your exact written number before we touch a rafter. That’s not a range, not a ballpark, not a “we’ll see when we get up there.” It’s a written price. Estimates are free. Call (903) 437-9164 and Neil will walk the job himself.

FAQs – Reflectix Insulation in New Braunfels
Yes, but only if the installation accounts for humidity. Reflectix works by reflecting radiant heat, and humidity doesn’t stop that. What changes in New Braunfels is the condensation risk around ductwork and the underside of the foil when river-driven dew points climb. We install differently here than we would in a dry climate, checking duct runs and ventilation first. Call (903) 437-9164 for an assessment specific to your attic.
Usually yes. We can install Reflectix as a radiant barrier on the rafters without disturbing blown-in fiberglass below, as long as the existing insulation isn’t compressed, blackened, or full of dust from a bathroom vent. In Oakwood Estates and Castle Ridge, we often find the original R-11 batts performing far below spec, and in those cases we’ll recommend replacement first. The quoted price covers whatever we recommend, and you’ll see it before we start.
No. Reflectix installed as a radiant barrier beneath the roof deck does not void shingle warranties in New Braunfels. The shingle manufacturers’ warranty concerns come from inadequate attic ventilation, not from reflective barriers. That said, we always check your ventilation setup before installing, because a poorly ventilated New Braunfels attic will bake any shingle, barrier or not.
In New Braunfels conditions, properly installed Reflectix typically lasts 10 to 15 years before surface dust, seam tape failure, or physical damage from roof work reduces its reflectivity. Homes near the river see faster degradation because humidity accelerates dust adhesion and tape failure along river-facing ridges. We inspect and advise on replacement timing as part of every estimate. Call (903) 437-9164 to schedule a look.
Yes, but with caveats. Reflectix can work as a crawl space barrier under a pier-and-beam home in Gruene, but the reflective surface must stay clean and the seams must stay taped to perform. Crawl spaces near the Guadalupe carry high humidity, which means condensation risk is real. We evaluate each crawl space individually and recommend the right product and installation method. Call (903) 437-9164 and we’ll come see what’s under there.
