Owens Corning Wall Insulation in Schertz: What to Know First
We provide independent Owens Corning wall insulation in Schertz, typically completing drill-and-fill and injection foam jobs in one day with a written price delivered before any work starts. Most Owens Corning wall insulation projects in the Schertz corridor run between $2,800 and $5,400 depending on wall cavity depth, existing condition, and whether the home needs air sealing first.

This page is for homeowners in Schertz, Cibolo, and the I-35 corridor who have Owens Corning insulation products in their walls and need injection foam, drill-and-fill retrofit, exterior wall insulation, or interior soundproofing. We work on Owens Corning EcoTouch, Thermafiber, and FOAMULAR lines daily, and we do not require manufacturer authorization to service them properly.
How Owens Corning Products Fail - and How We Fix Them
- EcoTouch PINK Fiberglas Batt settling in 2×4 walls. The 3.5-inch batt compresses over 10-15 years in Schertz’s heat-cycling climate, dropping below its labeled R-13 as gravity and vibration take hold. We diagnose settled cavities with borescope inspection, then dense-pack with Owens Corning ProPink L77 loose-fill or inject closed-cell foam to restore full contact with the stud bay.
- Thermafiber Mineral Wool moisture retention in south-facing walls. Thermafiber’s density resists fire but can wick and hold humidity when the exterior vapor barrier fails, a common issue in Schertz homes built 2005-2015 with inadequate housewrap detailing. We pull affected batts, remediate the cavity, install proper vapor retarder, and replace with conditioned material matched to the wall’s drying potential.
- FOAMULAR XPS board shrinkage at foundation-wall transitions. The rigid foam can pull 1/8 to 3/16 inch away from the sill plate after repeated summer expansion cycles, creating a thermal bypass we regularly find in Schertz’s Sedona subdivision and similar 1990s-2000s construction. We remove compromised boards, reseal the gap with compatible sealant, and reinstall or upgrade to a more dimensionally stable assembly.
- ProPink blown-in wall system density failures from original under-blowing. Owens Corning’s blown-in wall system requires 1.5 pounds per cubic foot minimum density to prevent settling; we find original installs at 1.1-1.2 pcf regularly in Schertz retrofits where the contractor rushed the job. We re-blow to specification using our own density-meter verification, or convert to injection foam where cavity access allows.
- Sound attenuation batt compression from improper installation. Owens Corning Acoustic batts lose their noise-reduction coefficient when compressed into 16-inch on-center bays meant for 24-inch spacing, a mistake we see in Schertz’s newer townhome construction. We reinstall at proper loft or switch to Thermafiber SAFB where the assembly requires higher density without compression.
Our Owens Corning Wall Insulation Process

- 1
Pre-work blower-door test and thermal imaging. We pressurize the house to measure baseline air leakage in CFM50, then run a FLIR scan to locate thermal bypasses in the wall plane. You get the before number in writing.
- 2
Cavity inspection with borescope and moisture probe. We drill 5/8-inch inspection ports in inconspicuous locations to verify existing Owens Corning product condition, check for mold, and confirm stud bay depth. No guesswork on material selection.
- 3
Air sealing before insulation - always. Top plates, electrical penetrations, and plumbing stacks get sealed with appropriate caulk or foam. Seal the leaks first. Then insulate. The attic doesn’t care how thick the insulation is if the air is still moving through it.
- 4
Material selection: OEM-compatible or direct replacement. We source Owens Corning products through our supplier network when the job calls for matching existing assemblies, or specify Johns Manville, Knauf, or Rockwool equivalents where performance or availability favors a switch. No proprietary lock-in.
- 5
Installation with density verification or depth-stick documentation. Blown-in jobs get real-time density metering; batt jobs get photo-logged depth sticks at multiple wall locations. Every cavity is accountable.
- 6
Post-work blower-door test and photo record delivery. We run the second pressurization reading, calculate your air leakage reduction, and deliver printed thermal images, depth-stick photos, and the blower-door comparison before we leave. Written warranty and 365-Day Done Right Promise included.

FAQs
No - manufacturer warranties on insulation products cover material defects, not subsequent modifications by independent service providers. As an independent Owens Corning service provider, we document our work so any future material defect claim remains traceable to original manufacture versus our installation. Keep your written scope and photo record with your home files. Call (830) 402-5240 if you need help interpreting warranty language on your specific product line.
We match Owens Corning products where the line remains active, and we stock EcoTouch, Thermafiber, and FOAMULAR through our supplier network. For discontinued lines, we specify the closest-performing equivalent from Owens Corning or another manufacturer we carry, and we document the substitution in your written scope. Interior walls get plug-and-texture repair on drill ports; exterior walls get matched siding or stucco patch. Call (830) 402-5240 to discuss your specific wall finish.
Spot repair runs 40-60% less than full removal, but only makes sense if the remaining batt is dry, uncompressed, and accessible. We make that call after borescope inspection, not before. In Schertz’s climate, settled batts in south or west walls often have moisture history that favors full replacement. We quote both options when both are viable. Call (830) 402-5240 for inspection and written pricing on both paths.
Most Schertz homeowners get an estimate within 48 hours of calling, and scheduling runs 5-10 business days depending on season and scope. Emergency situations - exposed cavities, active water intrusion - get prioritized. You’ll receive a text when your technician is en route, and a named technician, not a rotating crew. Call (830) 402-5240 to check current availability.
We source materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, and others - no proprietary lock-in. We default to Owens Corning when matching existing assemblies or when the homeowner specifies it, and we recommend alternatives when performance, availability, or assembly requirements favor them. Every material choice is documented in your written scope before work begins. Call (830) 402-5240 to discuss options for your specific wall assembly.
