Owens Corning Blown-In Insulation Nationwide

Owens Corning Blown-In Insulation in New Braunfels: What to Know First

As an independent Owens Corning service provider, we install and upgrade blown-in insulation systems for New Braunfels homeowners using Owens Corning AttiCat, ProCat, and EnergyComplete lines, with most attic jobs completed in one day and a written price delivered before any work starts. We don’t guess at performance - we run a blower-door test, a pressurization diagnostic that measures how many cubic feet of conditioned air your house leaks per minute, before we touch anything and again when we’re done. Most Owens Corning blown-in jobs in the New Braunfels area run between $1,800 and $3,400 for a typical 2,000-square-foot attic, depending on existing depth and air-sealing needs.

This page is for homeowners who already have Owens Corning insulation in their attic or walls and need more of it, better of it, or a fix for what’s failing - not a sales pitch for switching brands.

How Owens Corning Products Fail - and How We Fix Them

• AttiCat PINK Fiberglass Blown-In settling below labeled R-value in Guadalupe Valley heat. Owens Corning labels AttiCat at R-49 when blown to 18.5 inches, but we’ve measured settled depths of 14-16 inches in New Braunfels attics after three to five summers of 100-plus-degree roof deck temperatures. The glass fibers don’t degrade, but thermal cycling causes compaction near the eaves where roof pitch is steepest. We remove the settled material only if it’s contaminated, then blow fresh AttiCat to 20 inches with a settled-density target, and we photograph the depth markers every four feet for your record.
• ProCat LooseFill density gaps above top plates in older slab homes. ProCat Professional Series is marketed for consistent coverage, but in New Braunfels ranch-style homes built 1975-1995 - common off Loop 337 and along the River Road corridor - the ceiling drywall butts directly against the top plate with no raised heel truss. That leaves a narrow wedge where the hose can’t maintain proper velocity, creating a thermal bridge, a gap where framing members conduct heat past the insulation. We dense-pack that wedge with hand-placed ProCat or seal it with Owens Corning EnergyComplete spray foam before blowing the field, so the R-value isn’t undercut by geometry the blower can’t reach.
• EnergyComplete sealant failure at recessed can lights and plumbing stacks. Owens Corning’s EnergyComplete system pairs blown-in fiberglass with a water-based acrylic sealant sprayed at penetrations. In attics with poor ventilation - we’ve seen this repeatedly in homes near Landa Park with original gable vents and no ridge vent - the sealant stays damp longer than specified and loses adhesion at PVC plumbing stacks, which expand and contract with hot water use. We strip failed sealant back to sound substrate, replace it with a hybrid approach using EnergyComplete where appropriate and fire-rated caulk at active penetrations, then verify with a smoke pencil under blower-door depressurization.
• AttiCat hose static causing uneven distribution in long attic runs. The AttiCat blowing machine is designed for hose runs under 150 feet. In larger New Braunfels homes, especially the 3,000-plus-square-foot builds in Vintage Oaks and Copper Ridge, contractors sometimes stretch a single hose to 200 feet or more to avoid resetting the machine. Static buildup reduces fiber loft; you get dense clumps near the hose end and thin coverage at the far eaves. We stage the blower at a midpoint access, typically a gable vent or temporary roof port, keeping hose runs under specification and using a second technician to rake and verify depth in real time.
• Moisture accumulation in ProCat installed over unsealed ceiling penetrations. ProCat’s binder treatment resists moisture, but it isn’t waterproof. When warm, humid New Braunfels air leaks through unsealed electrical boxes or bath-fan housings in winter, it condenses on the cold roof deck above the ProCat. We’ve found stained, clumped ProCat in attics near the Comal River where the morning humidity runs higher than the IH-35 corridor. We don’t blow new insulation over wet old material - we remove the damaged section, seal the air leak with fire-stop foam and tape, let the deck dry verified with a moisture meter reading under 18 percent, then install fresh ProCat with a vapor-permeable baffle at the eave.

Our Owens Corning Blown-In Insulation Process

1. 1
   Call and scope. A live person answers, 24/7. We schedule a site visit, not a phone estimate. You get a text when your technician is en route, with a name and photo.
2. 2
   Blower-door test and attic inspection. We pressurize the house to 50 Pascals and record the CFM50 reading - your baseline. Then we enter the attic with a photo rig and document existing insulation depth, condition, and every visible penetration. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
3. 3
   Written price and material spec. We specify Owens Corning line, target R-value, and air-sealing scope. If your existing insulation is sound, we note “top-up over existing.” If removal is needed, we itemize it. No work starts without your signature on a fixed price.
4. 4
   Air sealing first, then insulation. Top plates, can lights, plumbing stacks, and chimney chases get sealed before the blower runs. This is non-negotiable - we will not blow Owens Corning product over an unsealed attic floor.
5. 5
   Installation with real-time depth verification. We set depth markers, blow to spec, and rake for even distribution. A second technician photographs every quadrant.
6. 6
   Post-test, cleanup, and documentation. We run the blower-door again and print the before-and-after comparison. You receive the written scope, photo record, and CFM50 results before we leave. The 365-Day Done Right Promise applies from that moment.

What Owens Corning Blown-In Insulation Costs in New Braunfels

Homes near the Guadalupe River or in flood-adjacent zones like those off River Road sometimes need additional vapor-barrier assessment, which we itemize separately. We also carry Reflectix and other brands if your project benefits from a hybrid approach - no proprietary lock-in. Call (830) 243-6352 for a free estimate with exact numbers for your attic.

Why New Braunfels Homeowners Call Topside Attic Insulation New Braunfels for Owens Corning Work

We’ve sealed and insulated over 9,000 homes since 2016, and the ones in New Braunfels keep us honest about humidity, hill-country temperature swings, and the specific geometry of slab-on-grade construction common here. Wes Okafor and our crew have worked attics off the River Road corridor near the Guadalupe, where stack-effect air leakage in older slab homes tends to run higher than homeowners expect - we’ve seen pre-seal blower-door readings above 5,000 CFM50 in houses where the owner assumed the attic was “pretty well insulated.”

Every job gets a written price before any work starts, a documented photo record, and printed blower-door results. If we miss something, the 365-Day Done Right Promise means we make it right - backed by a written scope and warranty you already have in hand. Calls are answered by a live person, 24/7, and our technicians are background-checked, uniformed, and named in the text we send when they’re on the way.
