Owens Corning Attic Insulation Nationwide

Owens Corning Attic Insulation: The Boerne Owner’s Guide

We stock and install Owens Corning-compatible attic insulation systems in Boerne, with most complete attic floor jobs running between $2,400 and $4,800 depending on square footage and whether air sealing is needed first. Same-day installation is available when we have your measurements and photos ahead of the visit. Most Boerne homeowners discover their Owens Corning insulation is failing when upstairs rooms won’t hold temperature despite the AC running constantly, or when they find compressed, discolored batts in the attic that have settled below the original R-value rating printed on the Kraft facing.

Which Owens Corning Models This Applies To

Owens Corning produces several attic-specific product lines, and matching the right material to your existing installation matters for thermal performance and code compliance in Kendall County. The most common systems we encounter in Boerne homes are the Pink Fiberglas Insulation batts (R-30 through R-49, available in standard and high-density “Cathedral Ceiling” variants), AttiCat Blown-In PINK Fiberglas (system-bagged loose fill designed for their blowing equipment), and ProPink L77 PINK Fiberglas loose fill used in professional applications.

Identification is straightforward if you know where to look. Batt products carry a printed Kraft paper facing with the R-value, dimensions, and Owens Corning logo; the facing should face the conditioned side in our climate zone. Blown-in systems leave a telltale pink, cotton-candy-like loose fill with a consistent fiber diameter distinct from yellow or white competitive products. For AttiCat systems, check whether the original installer left a system card or documentation in the attic, often stapled to a truss near the access hatch.

We are an independent service provider with no affiliation to Owens Corning. We source their materials through standard distribution channels alongside Johns Manville, Knauf, Rockwool, and others, which means we can match your existing Owens Corning installation or recommend an equivalent if supply or pricing favors another manufacturer. The OEM-versus-aftermarket question rarely applies to fiberglass insulation itself, but it does matter for vapor retarders, baffles, and air-sealing accessories that complete the system.

Signs Your Owens Corning Attic Insulation Is Failing

• Uneven temperatures between rooms on the same HVAC zone. When Owens Corning batts compress or shift, they leave thermal bypasses. We see this most often above west-facing bedrooms in Boerne homes where summer heat drives the attic well past 140°F and compressed R-30 performs closer to R-15.
• Visible settling or gaps along top plates and penetrations. Blown-in fiberglass settles naturally over time, typically 1-2 inches in the first five years. If your attic floor shows pink valleys between truss bays or bare spots near light fixtures, the original coverage depth has dropped below what the label promised.
• Moisture staining on ceiling drywall or attic sheathing. Owens Corning fiberglass itself doesn’t rot, but it can hold moisture against wood if a vapor retarder was omitted or installed backward. In Boerne’s humid shoulder seasons, we’ve pulled saturated batts from homes near the Cibolo Creek watershed where bulk air leakage carried conditioned air into cold attic cavities.
• Ice dam evidence in winter or excessive summer cooling load. Even in Central Texas, brief freeze events reveal insulation failures. If you had icicle formation at eaves last February, heat was escaping through thin or bypassed insulation and melting roof snow from below.
• Rodent disturbance or nesting material mixed with fibers. Owens Corning fiberglass is inedible, but rodents tunnel through it for nesting. Disturbed batts with compression trails, droppings, or acorn caches indicate the thermal barrier has been compromised and may require removal before replacement.

Replacement Cost & What’s Included

Most Owens Corning attic insulation replacements in Boerne run between $2,400 and $4,800 for a typical 1,800-2,800 square foot home, with smaller partial replacements starting around $1,200. The range depends on three factors: whether removal of existing material is required (add $0.75-$1.25 per square foot), whether air sealing of top plates, can lights, and penetrations is needed first, and whether we’re matching existing R-value or upgrading to current IECC standards for Climate Zone 2.

Every job includes a written price before work starts, a Documented Photo Record of conditions found and work completed, and on applicable jobs, before-and-after blower-door readings so you can verify the air-sealing result in CFM50. Our 365-Day Done Right Promise applies to all completed work. We do not charge for estimates, and we offer a Free Second Opinion on any written estimate you’ve already received.

DIY or Call Us?

There’s nothing inherently dangerous about handling Owens Corning fiberglass insulation, but there are practical limits to what a homeowner should attempt. You can safely inspect your attic with a flashlight and N95 mask, measuring existing batt thickness against the labeled R-value and photographing disturbed areas for us to review. What goes wrong in DIY replacement is almost always air sealing: homeowners blow new insulation over unsealed top plates and can light housings, which perpetuates the stack-effect leakage that made the old insulation underperform.

We also see compressed installation, reversed vapor retarders, and blocked soffit vents that create moisture problems two seasons later. Fiberglass doesn’t itch for a day and then quit; improper installation costs you every month on your utility bill. Seal the envelope first. Then fill it. If you want the numbers on paper, call (830) 529-7780 and we’ll run a blower-door test before we quote anything.
