Owens Corning Attic Insulation Nationwide

Owens Corning Attic Insulation: The Converse Owner’s Guide

Most Owens Corning attic insulation jobs in Converse run between $1.80 and $3.20 per square foot installed, depending on the R-value you need and whether the attic floor has been air-sealed first. We stock Owens Corning PINK blown-in fiberglass and batts on every truck, and we can usually inspect and quote same-day. Homeowners in Converse typically figure out something’s wrong when the upstairs bedrooms won’t cool below 78 degrees in July, or when their CPS Energy bill jumps 30% year-over-year despite the thermostat staying put.

Which Owens Corning Models This Applies To

Owens Corning makes two attic products you’ll see in Converse homes: the AttiCat PINK blown-in fiberglass (system R-values from R-19 to R-60) and the ProCat loose-fill used more often in new construction. The AttiCat system uses a blowing machine that conditions the fiberglass for better coverage, so if you’re adding to existing PINK insulation, you need matching material or you’ll get thermal drift at the boundary, a measurable drop in R-value where old meets new.

To identify what you have, check for the Owens Corning logo printed on the batts or the loose-fill bags left in the attic by the original installer. The AttiCat system also leaves a small specification card near the attic hatch noting the installed R-value and date. If you can’t find it, we carry a density gauge on the truck, a tool that measures pounds per cubic foot, to distinguish AttiCat from generic blown-in.

We’re an independent service provider, not affiliated with Owens Corning, but we source their materials through authorized distribution. For most Converse attics, we recommend sticking with OEM Owens Corning if you’re topping off an existing PINK installation. Switching to a different fiber type, like Johns Manville or GreenFiber cellulose, can work but requires a separation barrier to prevent settling incompatibility.

Signs Your Owens Corning Attic Insulation Is Failing

• Uneven temperature zones between rooms. When AttiCat fiberglass settles or gets disturbed by rodent activity, it creates thin spots. We see this often in older Converse ranch homes near Foster Road, where original R-19 batts have compressed to R-13 or lower in the center of the attic.
• Ice damming on the roof edge in winter. Heat escaping through under-insulated attic planes melts snow from underneath; the water refreezes at the cold eave. Owens Corning insulation that’s been wet from a roof leak loses up to 40% of its R-value even after drying, because the binder that keeps fibers fluffed breaks down.
• Dusty air from ceiling registers. If your blown-in PINK is pulling into the HVAC return through a leaky ceiling chase, the insulation is essentially migrating out of the attic and into your air handler. This usually means the attic floor wasn’t sealed before the insulation went in, a shortcut we won’t take.
• Visible moisture or mold on the attic sheathing. Owens Corning fiberglass doesn’t rot, but it can hold condensation against the roof deck if vapor drive from the living space isn’t controlled. In Converse’s humid shoulder seasons, this shows up as dark streaking on the plywood by September.
• Insulation level below the attic floor joists. The Department of Energy recommends R-38 to R-60 for our climate zone. If you can see the tops of the joists, you’re likely at R-19 or less. We measure with a ruled probe during every inspection and photograph the reading for your record.

Replacement Cost & What’s Included

For a typical 1,500-square-foot attic in Converse, full removal and replacement with Owens Corning AttiCat runs between $2,700 and $4,800. That includes:

• Removal of existing compromised insulation and disposal
• Air sealing of top plates, can lights, and penetrations (we don’t blow over leaks)
• Installation of new Owens Corning PINK to your chosen R-value
• Before-and-after blower-door test with printed CFM50 readings
• Documented Photo Record delivered before we leave

Add $400-$700 if we find active rodent contamination requiring sanitization first. Topping off existing sound insulation without removal drops the range to $1,400-$2,400. Every job gets a Written Price Before Any Work Starts, no exceptions, and our 365-Day Done Right Promise covers the installation and materials.

DIY or Call Us?

You can safely check your insulation depth with a ruler and photograph any obvious thin spots or moisture damage. If you’re comfortable in the attic, look for the Owens Corning specification card near the hatch and note the date.

What you shouldn’t do: add new blown-in over old without sealing the attic floor first, or disturb insulation that may contain rodent waste without proper PPE and HEPA containment. Fiberglass itself isn’t toxic, but the dust is a lung irritant, and disturbed batts release particles that settle in living spaces through ceiling penetrations. The bigger risk is covering air leaks with more insulation and thinking you’ve fixed the problem, the “bury and hope” approach that we see constantly in Converse homes built between 1965 and 1995.

We carry Owens Corning PINK on every truck, and we can inspect, test, and quote today. Call (830) 420-0953 or text us a photo of your attic hatch area for a quick preliminary look.
