How Owens Corning Products Fail - and How We Fix Them

• AttiCat PINK Blown-In Insulation settling in San Marcos heat. The loose-fill fiberglass compresses over time in attics that hit 140°F through July and August, creating thermal bypasses near the eaves. We measure the settled depth with a ruled probe, calculate the percentage of original R-value lost, and recommend redensification or top-off with conditioned air sealing first - never over an unsealed attic floor.
• FOAMULAR NGX board shrinkage at rim joists. Owens Corning’s extruded polystyrene can pull 1/8 to 3/16 inch away from framing members in our clay-heavy soils, which shift with seasonal moisture. The gap becomes a convection highway. We remove the compromised boards, seal the rim joist with closed-cell spray foam to the full depth, and publish before-and-after blower-door numbers so you see the actual air leakage reduction.
• PINK Next Gen Fiberglass batts with failed Kraft facing. The asphalt-impregnated paper facing delaminates in San Marcos attics where humidity spikes during spring storms, causing the vapor retarder to sag and create gaps. We document the failure with thermal imaging, remove the degraded batts, and replace with unfaced batts plus a continuous air barrier - the fix that lasts.
• ProCat Loose Fill installed without top-plate sealing. We see this constantly in 1980s and 1990s slab-on-grade homes near the Texas State University corridor, where the original contractor blew insulation directly over leaky top plates - the junction where wall framing meets ceiling drywall. The R-value tells you how slow heat moves through the material - the blower-door number tells you whether any of that matters. We seal every top plate with fire-rated caulk or foam before any new insulation goes in.
• Duration shingles with inadequate attic ventilation causing ice damming in rare freeze events. Owens Corning’s premium shingle line performs well, but when paired with an under-ventilated attic in San Marcos homes that still have original soffit blocking, winter heat buildup melts roof snow unevenly. Our audit maps intake and exhaust ventilation with flow hoods, then specifies baffled soffit vents and ridge vent corrections to protect the shingle warranty.

Our Owens Corning Home Energy Audit Process

1. 1
   Schedule and scope. A live person answers your call, confirms square footage and construction era, and emails a written price before we dispatch. You’ll get a text when your technician is en route.
2. 2
   Blower-door test - baseline. We install a calibrated fan in an exterior door and depressurize the house to 50 Pascals, recording the CFM50 reading - a single number showing how much conditioned air your envelope is losing. This is your before.
3. 3
   Thermal imaging and insulation inspection. Our FLIR camera maps surface temperature differentials across walls, ceilings, and duct runs while the house is under pressure. We probe Owens Corning batt and loose-fill depths, check for compression or moisture staining, and photograph every finding.
4. 4
   Duct leakage test if applicable. We pressurize the duct system and measure leakage to outside, critical in San Marcos homes with flex duct in vented attics where summer attic air gets pulled into the supply.
5. 5
   Written report and recommendation. You receive a documented photo record, the blower-door number, thermal images with annotations, and a prioritized scope with flat pricing for any air sealing or insulation work. No work starts without a second written price.
6. 6
   Post-work verification on completed jobs. If you hire us for the remediation, we run the blower door again and hand you a single printed page showing before and after air-changes-per-hour. Under Haven Standard: documented evidence, not claims.

What Owens Corning Home Energy Audit Costs in San Marcos

Homes built 1985-2005 in San Marcos, particularly the older neighborhoods between Hopkins Street and the university corridor, typically need more top-plate and penetration sealing than newer construction - that labor shows in the scope, not in surprise add-ons. We also service Reflectix radiant barrier systems when they’re part of the envelope problem. Call (737) 337-8049 for an exact quote - estimates are free, and we provide a free second opinion on any written estimate you’ve already received.

Why San Marcos Homeowners Call Topside Attic Insulation San Marcos for Owens Corning Work

We’ve sealed and insulated over 9,000 homes since 2016, every one with a written price before work started and a documented record when the crew left. Our technicians are background-checked and uniformed; calls are answered by a live person, 24/7, with no voicemail loops. Wes Okafor, who trained in building science at Dawson Technical Institute and has spent two decades diagnosing why attics fail rather than just filling them, requires before-and-after blower-door numbers on every applicable job. The 365-Day Done Right Promise applies to all completed work, and we source materials from Owens Corning, Johns Manville, Knauf, Rockwool, and others - no proprietary lock-in, ever. As an independent Owens Corning service provider, we have no manufacturer affiliation; our only obligation is to what the test data shows.
