This page is for homeowners who already have Owens Corning insulation products in their walls and need professional installation, replacement, or an upgrade - whether that’s EcoTouch PINK Fiberglas that has settled below the stud bay, Thermafiber mineral wool that needs supplementing, or a FOAMULAR rigid board detail that didn’t get sealed properly at the perimeter. Wes Okafor and our crew have worked Owens Corning systems across New Braunfels, from the older slab homes off River Road where stack-effect leakage runs higher than owners expect, to newer builds in Veramendi where the original batt installation left gaps at the top plates.
How Owens Corning Products Fail - and How We Fix Them
- EcoTouch PINK Fiberglas batts settling in exterior walls. The bonded glass fibers in Owens Corning’s residential batt line relax over 10-15 years in New Braunfels’ heat cycles, dropping from full stud-bay contact to a gap at the top plate. We find this most often in 1980s-2000s homes in the Gruene and Original Town neighborhoods. Our fix: extract the settled batt, air-seal the top plate and electrical penetrations with acoustic sealant, then dense-pack the cavity with blown-in fiberglass or injection foam to eliminate future settling.
- FOAMULAR XPS rigid board pulling away at foundation walls. Owens Corning’s extruded polystyrene boards shrink slightly over time, especially where basement or crawl-space perimeter walls see seasonal moisture swing. In New Braunfels’ clay-heavy soils, that gap becomes a convection channel. We remove the compromised board, seal the rim joist and sill plate with closed-cell spray foam, then reinstall FOAMULAR or upgrade to a higher-R assembly with taped seams and proper termite inspection gaps per local code.
- Thermafiber RainBarrier commercial-grade mineral wool absorbing water in retrofit cavities. This product line is engineered for exterior cladding applications, but we’ve found it misapplied in interior wall retrofits by previous contractors who didn’t read the vapor-profile requirements. When it gets wet behind stucco in New Braunfels’ driving rains, it holds moisture against the sheathing. We pull the affected batts, dry the cavity with directed airflow, and replace with a hydrophobic blown-in system matched to the actual wall assembly.
- ProPink LooseFill blown into walls without prior air sealing. Owens Corning’s loose-fill fiberglass performs well when dense-packed, but blown over unsealed top plates and wire holes it becomes a filter - catching dust while conditioned air streams past. We see this in quick retrofits throughout the Oak Run and Creekside areas. Our approach: blower-door test first, seal every penetration we can access, then re-blow to proper density with documented before-and-after CFM50 readings.
- AttiCat system hoses leaving voids in wall cavities. The AttiCat blowing machine is designed for attic floors, not wall retrofits; the hose diameter and air velocity create inconsistent pack density in vertical cavities. We’ve opened walls where the bottom third was packed tight and the top third was hollow. We re-do these with a dedicated wall-injection rig, slow-fill technique, and infrared verification to confirm no gaps remain.
Our Owens Corning Wall Insulation Process
- 1
Call and scheduling. A live person answers 24/7. We book a site visit, send a text with your technician’s name when they’re en route - Haven Standard: Arrive on schedule.
- 2
Blower-door test and infrared scan. We pressurize the house to measure CFM50 leakage, then use thermal imaging to map where exterior walls are bleeding conditioned air. You get the pre-job number in writing.
- 3
Written price and scope. We specify Owens Corning OEM or equivalent aftermarket materials, line-item the air-sealing work, and deliver a flat price before any work starts. No exceptions.
- 4
Air sealing first, then insulation. Top plates, electrical boxes, conduit penetrations, and any rim joist access get sealed with appropriate caulk or foam. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
- 5
Installation with density verification. Blown-in fiberglass is packed to 1.5-2.0 lbs per cubic foot; injection foam is monitored for full-cavity fill. Infrared spot-checks confirm no voids.
- 6
Post-test, photo record, and documentation. We run the blower door again, print your before-and-after CFM50 readings, and deliver a Documented Photo Record with the written warranty. The 365-Day Done Right Promise applies from that moment.

Why New Braunfels Homeowners Call Topside Attic Insulation New Braunfels for Owens Corning Work
We’ve sealed and insulated 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, uniformed, and trained on Owens Corning product lines specifically - they know the difference between an EcoTouch batt and a Thermafiber commercial specification, and they know when a Reflectix radiant barrier detail makes sense as a supplement rather than a replacement. We don’t push proprietary products; we source from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber so the solution fits the wall, not our vendor agreement. The 365-Day Done Right Promise is in writing before anyone starts, and a live person answers the phone 24/7 if something doesn’t feel right.
FAQs
No - properly installed wall insulation does not void Owens Corning product warranties, though damage caused by improper installation (moisture trapping, compression below labeled R-value) is not covered. We document our install method and materials so any future warranty claim has clear evidence of what was done and when. Bring us your existing warranty paperwork during the estimate and we’ll flag any sections relevant to your wall assembly.
We source both. For matching existing EcoTouch batts in a repair or extension, we typically use OEM to maintain consistent density and thermal performance. For retrofits where we’re upgrading an assembly, we may specify Knauf Jet Stream or Johns Manville Climate Pro blown-in fiberglass if the density and R-value spec better fit the cavity. We explain the choice in your written scope, with no proprietary lock-in.
In most New Braunfels homes with settled PINK Fiberglas, removal and dense-pack replacement costs 15-25% more than spot-repair topping, but delivers roughly double the effective R-value and eliminates the settling problem permanently. Spot repair is viable only if the existing batt is still in reasonable condition and the cavity access is limited. We quote both approaches when possible so you can see the trade.
Most drill-and-fill retrofits in a typical New Braunfels single-family home are completed in one day; larger homes or jobs requiring interior drywall removal run two days. We schedule within 3-5 business days of estimate approval for standard work, and offer emergency scheduling for homes with active comfort or moisture issues. Call (830) 243-6352 to check current availability - estimates are free.
Yes. On every applicable job we provide before-and-after blower-door readings - a pressurization measurement that shows, in a single figure, how much conditioned air your home was losing before and after the work. You get printed CFM50 numbers, infrared documentation, and a photo record. Wes keeps copies filed by address, which has helped more than one homeowner answer a buyer’s inspector questions years later.
