Reflectix Insulation Service Nationwide

Why Seguin Homeowners Choose Reflectix Insulation

Topside Attic Insulation Seguin provides independent Reflectix in Seguin insulation service across Seguin and the surrounding Hill Country edge - we are not affiliated with or authorized by Reflectix, but we stock genuine Reflectix rolls and foil tape and install them to the product’s actual specifications, not the shortcut version. In Seguin’s climate, that means maintaining the required air gap between foil and roof deck, adding real R-value on the attic floor, and documenting the result with before-and-after blower-door readings so you know what changed.

Reflectix radiant barrier products show up in a lot of Seguin attics. Some were installed by homeowners after a weekend hardware-store run. Others came with a new-build package that didn’t include enough attic-floor insulation underneath. We’ve worked on Reflectix in New Braunfels and post-WWII wood-frame houses near the downtown square, in ranch-style homes from the 1960s, and in newer construction where the builder treated radiant barrier as a substitute for actual insulation. It isn’t. We treat it as one layer of a complete envelope fix - sealed first, then insulated, then tested.

Wes Okafor, our owner and lead technician, learned the thermal envelope side of this trade at Triton College in River Grove, IL, and he’s spent over two decades watching what happens when reflective foil gets installed without the air gap the physics require. The report goes home with you - the numbers do the talking.

Why Trust Topside Attic Insulation Seguin for Your Reflectix Insulation?

We know the Reflectix product line by its real model numbers, not generic descriptions. We stock Reflectix Double Reflective Insulation Roll in the 48-inch widths - both the BP48010 (10-foot) and BP48025 (25-foot) - along with Reflectix Staple Tab Insulation (ST16025) for rafter-bay installs and Reflectix Reflective Foil Tape (FT210, 2-inch by 30-foot) for seam sealing. We also carry quality aftermarket foil tape and butyl flashing tape for situations where Seguin’s humidity demands something the OEM tape doesn’t provide.

Our crew has repaired and reinstalled Reflectix across Seguin’s housing stock, including Reflectix service in Cibolo and jobs in neighborhoods near Guadalupe Regional Medical Center where older attic framing means we almost always find air leaks through top plates and can lights before we touch a single roll of foil. We document every find with photos, seal the leaks, then install or repair the radiant barrier correctly. On applicable jobs, we run a blower-door test - a pressurization diagnostic that measures how much conditioned air your house loses per hour - both before and after, and hand you a printed report with the actual ACH50 numbers.

We’re independent. That means we quote what your attic actually needs, not what a manufacturer program pushes. If your Reflectix is intact but your attic floor only holds R-19 in a climate that wants R-38 to R-60, we’ll tell you to keep the barrier and add Attic Insulation services like blown-in insulation. No rip-out required. No upsell theater. Written price before any work starts, documented photo record when we leave, 365-Day Done Right Promise on everything.

Common Reflectix Insulation Problems We Fix in Seguin

• Foil facing delaminates from direct roof-deck contact. Reflectix stapled flat against hot roof sheathing - the most common mistake we see in Seguin - destroys the product. The foil layer bubbles and peels within a season or two because there’s no air gap to let heat dissipate. The attic runs hotter than before, and the homeowner wonders why they bothered. We see this pattern repeatedly on streets closest to the Guadalupe River, where attic humidity already pushes materials harder. Fix: pull the failed runs, reinstall across rafters with proper standoff, tape seams with Reflectix FT210 or humidity-rated aftermarket tape, and add baffles at soffits so intake air still flows.
• Staple-tab rolls installed with no air space, converting radiant barrier to heat conductor. Reflectix ST16025 is designed to hang below the rafters, not hug them. When it’s stapled tight, the aluminum foil conducts heat directly into the attic instead of reflecting it back toward the roof deck. We’ve measured attic temperatures 15 to 20 degrees higher than they should be after this mistake. The product didn’t fail - the install did.
• Reflectix used as sole attic “insulation” over bare joists. A radiant barrier has near-zero R-value by itself. In Seguin’s ASHRAE 2A climate, where summer attic temps exceed 150°F and humidity stays elevated into fall, that leaves the living space unprotected. We find this in older homes that never had adequate attic-floor insulation to begin with, and in quick flips where a shiny foil layer masked thin or missing batts. The fix is never more Reflectix on the roof - it’s blown-in cellulose or fiberglass on the floor, air-sealed first.
• Duct-wrapped Reflectix dulled by attic dust and failed seams. Reflectix wrapped around flex duct in unconditioned attics collects dust that degrades the low-emissivity surface. Worse, seams taped with generic HVAC tape or the wrong foil tape open up within a couple of seasons, letting conditioned air leak into the attic. We clean or replace the wrap, reseal with proper tape rated for our humidity, and verify with a duct-blaster test when the job calls for it.
• Reflectix blocking soffit ventilation after DIY installs. Homeowners run staple-tab rolls continuously from eave to ridge, covering soffit intakes and killing the airflow that radiant barrier systems depend on. Hot, stagnant air builds up. We install baffles, cut and retape the barrier to maintain the vent channel, and document the before-and-after attic temperature difference.

Reflectix Parts & Our Repair-vs-Replace Approach

We use genuine Reflectix rolls and Reflectix FT210 foil tape where the product itself is the point of the job - matching the original specification, maintaining warranty-safe practices, and ensuring seam tape that won’t degrade in Seguin’s river-valley humidity. Where we’ve found better performance, we use quality aftermarket foil tape or butyl flashing tape, and we tell you which we’re using and why before we start.

Our repair-vs-replace decision is straightforward. If your Reflectix is intact but poorly installed - wrong position, no air gap, blocked vents - we reposition and supplement, not rip out. If the foil facing has delaminated or the product has been crushed by foot traffic or rodent damage, we replace the affected runs. If your attic floor insulation is the real problem and the barrier is basically fine, we leave it and add blown-in insulation on top after air sealing. Written scope, written price, no work starts without both. Call (830) 549-6646 for an exact quote - estimates are free.

Our Reflectix Service Process - Step by Step

1. 1
   Diagnosis and blower-door baseline. We inspect your attic’s existing Reflectix installation, measure attic-floor insulation depth, identify air leaks through top plates and penetrations, and run a blower-door test to establish your home’s starting ACH50 - the air changes per hour at 50 Pascals of pressure.
2. 2
   Air sealing before any insulation work. Under our sealed-first rule, we seal top plates, can lights, wire penetrations, and duct boots with foam, caulk, or rigid blocking. No Reflectix goes up until this is done. The blower-door test is repeated to verify the seal.
3. 3
   Reflectix repair or reinstall with proper air gap. We pull failed runs, reinstall across rafters with correct standoff, tape seams with FT210 or humidity-rated aftermarket tape, and install baffles at soffits to protect ventilation. Attic-floor insulation is topped up with blown-in cellulose or fiberglass to R-38 or higher.
4. 4
   Post-install blower-door test and documentation. We pressurize again, record the new ACH50, photograph the completed work, and deliver your printed report with pre- and post-numbers, photos, and written warranty. The 365-Day Done Right Promise applies from that moment.
