Why Brushy Creek Residents Choose Us for Reflectix Service
We don’t guess at what a Brushy Creek attic needs. Wes Okafor, who leads our crew, grew up on Chicago’s South Side and picked up his first blower-door numbers at Olive-Harvey College before spending nearly two decades diagnosing air-sealing failures across Central Texas. He’s worked attics from Sun City Georgetown to homes backing the San Gabriel River corridor, and he won’t add a single bag of cellulose until every penetration is foam-sealed and the pre-job thermal images are documented.
That discipline matters in Brushy Creek more than most places. The CDP’s subdivisions were thrown up fast during Williamson County’s boom years, when builders met code with R-19 blown fiberglass and moved on. Now that original insulation has settled to somewhere between R-11 and R-14, and the sparse tree canopy these planned developments were built with means those attics bake. We know which Reflectix sales & service products actually fit the rafter spacing and ventilation patterns of these specific homes, and we stock genuine Reflectix rolls and tape so we’re not substituting generic mylar that loses emissivity in year three.
Every job starts with a written scope and price, and ends with a Documented Photo Record plus before-and-after blower-door numbers where air sealing is part of the work. Under our Haven Standard, you get flat pricing, a named technician, and a text when they’re on the way. No voicemail loops, no callback windows measured in business days.
Common Reflectix Insulation Problems We Solve in Brushy Creek

- Dust-killed radiant barrier on rafter undersides. Reflectix foil stapled to the bottom of rafters in 1990s Brushy Creek attics looks fine from below but the reflective face is coated with fine dust within 6-10 years, dropping emissivity by 40-60%. These low-pitch tract roofs don’t have the steep angle that sheds dust naturally. We test with an infrared thermometer to find the dead zones, then remove or overlay depending on condition.
- Foil laid flat on settled fiberglass with no air gap. Some Brushy Creek homeowners or prior contractors laid Reflectix perforated barrier directly on top of blown insulation. Radiant barrier needs an air space to reflect heat; without it, the foil becomes an expensive vapor retarder doing almost nothing. We measure the settled depth, calculate whether there’s clearance for a proper install, and rebuild the assembly correctly if there isn’t.
- Bubble foil trapping moisture in kneewalls. Two-story Brushy Creek homes from this era consistently have uninsulated or minimally insulated kneewalls where the second floor meets the attic. We’ve found Reflectix bubble foil slapped on these surfaces as a quick fix, but without proper sealing and backing it traps humid attic air against drywall. The foil delaminates, and surface mold follows. We pull it, air-seal the framing, and install proper insulation with a verified drainage plane.
- Ventilation choked by barrier installed over baffles. Reflectix run continuously from ridge to soffit without re-establishing intake airflow kills the ventilation cycle. In Brushy Creek’s 155-165°F summer attics, that stagnant heat cooks the top plate and shortens roof deck life. We detail every installation with proper baffle clearance and document it in the photo record.
- Reflectix used where it can’t solve the real problem. Settled R-19, cantilevered floors with open air paths, unsealed can lights - these are air-sealing and insulation problems, not radiant barrier problems. We’ll tell you honestly when Reflectix isn’t the right tool and recommend code-minimum fiberglass or spray foam instead of layering foil over a symptom.
Before
AfterReflectix Service in Brushy Creek: What Local Conditions Mean for Your Equipment
Here’s the specific Brushy Creek factor that shapes every Reflectix decision we make. The 1985-2005 tract homes here were permitted under Texas energy code that only counted attic insulation R-value and did not credit radiant barriers at all. Almost none of the original builders installed foil or reflective products, even though the CDP’s sparse tree canopy means these attics see full sun and 155-165°F peaks all summer long. That code history is why retrofitting Reflectix foil over the rafters of these specific subdivisions performs so well compared to surrounding areas with mature shade - you’re not adding redundancy to an existing system, you’re installing the first line of defense these homes never got.
In the Oaklands section of Brushy Creek we took on a 1997 two-story with a vaulted great room and a bonus room over the garage, where the upstairs bedrooms hit 8°F hotter than downstairs. Our tech found the original R-19 blown fiberglass settled to about R-11, no radiant barrier on the west-facing roof deck, and uninsulated kneewalls where the second floor meets the attic - so we air-sealed the kneewalls, blew in a top-up to R-38, and installed Reflectix Double Reflective foil stapled to the rafter undersides with a consistent 3/4-inch air space behind it. The homeowners reported the bonus room dropped from the high 80s to the mid-70s during the following August afternoons.
Seal the holes first. Then we talk about R-value. That’s how we approach every Brushy Creek service area home.
Reflectix Models & Products We Service in Brushy Creek

We work with the full Reflectix residential line and stock the products that matter for Central Texas attics:
- Reflectix Double Reflective Insulation Roll - foil/bubble/foil construction, our standard for rafter-deck radiant barriers where a 3/4-inch air space can be maintained.
- Reflectix Single Reflective Foil Insulation Roll - used where weight or clearance is limited, or as a supplement to existing insulation in specific detail areas.
- Reflectix Reflective Foam Core Insulation - R-8 and R-21 styles for kneewall and garage-ceiling applications where some R-value is needed alongside reflectivity, though we rarely use these without underlying air sealing.
- Reflectix Perforated Radiant Barrier Foil Roll - vapor-permeable, designed for attic floor applications where moisture management matters; we evaluate attic humidity before specifying.
We use genuine Reflectix branded rolls and tape for all radiant barrier and foil applications. Where the material’s emissivity rating matters, we will not substitute generic mylar or double-sided foil bubble. For fast Brushy Creek turnaround, we keep Double Reflective and Perforated Barrier rolls in stock locally.

FAQs - Reflectix Insulation in Brushy Creek
Yes, specifically because these homes were built without any radiant barrier credit in code. Adding Reflectix to the rafter deck addresses the radiant heat load that R-19 fiberglass was never designed to stop, especially in Brushy Creek’s full-sun attics. We typically pair it with Brushy Creek Attic Insulation top-up to R-38 for the full assembly. Call (254) 970-2136 for a thermal scan and written estimate.
Uninsulated kneewalls where the second floor meets the attic are the most common cause in Brushy Creek’s 1990s two-story homes, a code gap from that era. The hot attic air radiates through unsealed framing into bedroom walls. We air-seal the kneewall framing, install proper insulation, and verify with a blower-door test. Call (254) 970-2136 - we document the before-and-after numbers.
The material itself is rated for decades, but dust accumulation on the foil face in low-pitch Brushy Creek attics typically degrades performance 40-60% within 6-10 years. Proper installation angle, ventilation, and occasional inspection extend useful life. We assess existing installs with infrared thermometry and tell you honestly whether cleaning, overlay, or replacement is the right call.
No, not as a standalone solution. Bubble foil has minimal R-value and traps moisture against drywall in our humid summer conditions. We’ve removed failed bubble foil from Brushy Creek kneewalls where delamination and mold resulted. For garage ceilings and kneewalls, we specify Brushy Creek Spray Foam Insulation with verified air sealing, using Reflectix products only where they actually perform.
Yes. Reflectix radiant barrier is designed to reduce summer radiant heat gain; it does almost nothing to stop winter convective heat loss. The February 2021 freeze exposed how poorly these homes handle sustained cold. We recommend combining Reflectix with air sealing and adequate R-value insulation - typically R-38 in the attic - for year-round performance. Call (254) 970-2136 for a whole-envelope assessment.
