Owens Corning Attic Insulation Nationwide

Owens Corning Attic Insulation: The Schertz Owner’s Guide

We stock and install Owens Corning blown-in fiberglass attic insulation in Schertz with same-day availability on most jobs, and most attic insulation projects in Schertz homes run between $1,800 and $3,400 installed, depending on existing depth and square footage. Homeowners usually discover their Owens Corning insulation is failing when upstairs rooms won’t cool below 78°F in July, energy bills spike 30% or more year-over-year, or they spot thin, compressed, or water-stained batts while storing holiday decorations. In Schertz’s climate, with attic temperatures climbing past 140°F from May through September, insulation that was adequate in 2015 is often undersized by today’s standards.

Which Owens Corning Models This Applies To

Owens Corning produces several attic insulation lines, and knowing which you’re dealing with determines whether we match it or upgrade. The most common in Schertz attics is AttiCat PINK Blown-In Insulation, identifiable by the loose-fill fiberglass with the distinctive pink colorant, typically blown to R-30 to R-60 depth depending on when the home was built. Older installations may use Owens Corning EcoTouch PINK Fiberglas Batt Insulation, the rolled batt product with the product code printed on the kraft-paper facing, usually marked R-13, R-19, R-30, or R-38.

To identify your product, check for a printed label on any exposed batt facing or look for loose pink fiberglass between joists. The critical compatibility gotcha in Schertz: Owens Corning’s AttiCat system requires a minimum settled depth of 14.75 inches to achieve R-38, but many local installers stop at 12 inches, leaving you short of the Department of Energy’s recommended R-value for our climate zone. We also stock Reflectix radiant barrier products for hybrid systems. We are an independent service provider, not affiliated with Owens Corning, and we source materials from multiple manufacturers so we’re not locked into any single product line.

Signs Your Owens Corning Attic Insulation Is Failing

• Uneven temperatures room-to-room. When the master bedroom runs 8°F warmer than the hallway in summer, the insulation has likely settled below design depth or was never installed to full coverage. In Schertz, we see this constantly in homes built between 2015 and 2020 where builders met code minimum but not performance.
• Energy bills climbing without rate increases. If your CPS Energy or GVEC bill jumped 25-40% compared to the same month last year and your usage patterns haven’t changed, the thermal envelope is leaking more than it should. Insulation compresses over time, especially if it was installed over unsealed top plates.
• Visible compression, displacement, or gaps. Fiberglass batts lose R-value when compressed below their labeled thickness. We regularly find Owens Corning batts squashed to half their labeled depth by homeowners walking on them or crews using the attic for storage access.
• Moisture staining or mold on rafters or sheathing. Pink fiberglass doesn’t rot, but it holds moisture against wood when attic ventilation is inadequate. Schertz’s spring humidity spikes make this worse, and once mold appears, the insulation needs removal, not just topping off.
• Ice dam evidence in winter or excessive shingle heat in summer. Even in Central Texas, brief freeze events can create minor ice dams if attic heat loss is severe. More commonly, we see premature shingle curling from attic temperatures 20-30°F above what proper insulation would allow.

Replacement Cost & What’s Included

Most Owens Corning attic insulation jobs in Schertz run between $1,800 and $3,400 for a typical 2,000-square-foot home, with the final price driven by three factors: how much existing material needs removal versus topping off, whether the attic floor requires air sealing before new insulation goes in, and the target R-value you want to hit. A straight top-off of AttiCat blown-in to reach R-38 sits at the lower end. Full removal of compressed or contaminated batts, plus air sealing of top plates and can lights, then new blown-in to R-49, pushes toward the higher end.

Every job includes our Written Price Before Any Work Starts under Haven Standard Clause 1, a Documented Photo Record of pre-existing conditions and post-install depth measurements, and the 365-Day Done Right Promise. On jobs where we’re also air sealing, you’ll receive before-and-after blower-door numbers showing the actual CFM50 reduction. We don’t do “call for pricing” because the price should be in writing before anyone lifts a tool.

DIY or Call Us?

There’s no high-tension danger here like a garage door spring, but attic work carries its own risks. A homeowner can safely check existing insulation depth with a ruler and photograph any product labels for identification. What goes wrong fast: stepping through drywall between joists, disturbing asbestos-containing vermiculite in pre-1990 homes, or blowing insulation over live knob-and-tube wiring without an electrician’s clearance.

The bigger problem is sequencing. We’ve lost count of Schertz attics where someone added R-30 over an unsealed attic floor, burying air leaks they’ll never find again and spending money on the wrong problem. Seal the leaks first. Then insulate. The attic doesn’t care how thick the insulation is if the air is still moving through it. For a free written estimate with no work obligation, call (830) 402-5240. We’ll read your existing situation with you and show you exactly what the documentation will look like before we start.
