How Owens Corning Products Fail - and How We Fix Them
- Owens Corning AttiCat blown-in fiberglass settles below labeled R-value in Tustin’s dry heat. The AttiCat PINK system performs well when installed to proper depth, but we’ve measured settled product in Tustin Legacy homes that dropped from R-38 to R-26 after seven to ten years of thermal cycling. Our fix: complete removal, air seal top plates and can-light penetrations, then reinstall to true depth with a depth card photo in your Documented Photo Record.
- Owens Corning EcoTouch batts degrade when prior roof leaks introduced moisture. The formaldehyde-free binder breaks down with repeated wet-dry cycles, common in older Tustin Ranch homes with original tile roofs. You’ll smell a faint ammonia odor on hot days. We remove the compromised batts, treat the deck for mold if needed, and replace with fresh product only after verifying the leak source is fixed.
- Owens Corning FOAMULAR rigid board delaminates in unvented cathedral ceilings. The XPS facing separates from the core when trapped moisture can’t escape, a problem we see in Tustin Meadows townhomes with complex rooflines. We remove the delaminated boards, assess whether the assembly needs venting or a switch to closed-cell spray foam, and document the assembly change with thermal imaging.
- Owens Corning QuietZone acoustic batts in interior walls compress from improper storage or rodent nesting. These batts lose their sound-dampening density and their thermal performance. In Tustin’s older subdivisions near the 55 freeway, we’ve found compressed QuietZone behind knee walls where roof rats nested. We remove, sanitize, and replace with fresh batts after rodent proofing per our scope.
- Owens Corning ProCat loose-fill in mixed attic/crawl applications drifts from vibration and HVAC duct movement. The product migrates toward low points, leaving bare spots near the perimeter. We see this in Tustin’s post-2005 builds with flex duct runs through conditioned attics. Our fix: remove and regrade, or switch to a stabilized blown-in product with better inter-fiber bonding for that specific geometry.
Our Owens Corning Insulation Removal & Replacement Process
- 1
Call and scope. A live person answers. We schedule a site visit, and you receive a text with your technician’s name when they’re en route. Under Haven Standard: Arrive on schedule, you get a named technician.
- 2
Attic inspection and blower-door test. We pressurize the house to measure air leakage in CFM50 - cubic feet per minute at 50 pascals of pressure - so we know how much conditioned air you’re losing before we touch anything. Wes Okafor logs the starting number and photographs existing Owens Corning product labels for parts verification.
- 3
Written price and scope. We deliver a flat price, written scope, and written warranty before anyone lifts a tool. Haven Standard Clause 1. No exceptions.
- 4
Air seal first, then remove. Seal the leaks first. Then insulate. The R-value on the bag means nothing if conditioned air is moving through the gap around that recessed can. We seal top plates, can lights, plumbing penetrations, and chimney chases before insulation removal begins.
- 5
Removal, disposal, and replacement. HEPA-contained removal for contaminated product. OEM or quality aftermarket Owens Corning replacement per your written scope. We also carry Reflectix and other brands if the assembly calls for a hybrid approach.
- 6
Post-work verification. Blower-door test repeated, thermal images captured, R-value report written. Your Documented Photo Record includes before-and-after numbers, depth verification, and the written warranty. The 365-Day Done Right Promise applies from this moment.

FAQs
No - Owens Corning’s product warranty covers manufacturing defects, not installation or removal by an independent contractor. As an independent Owens Corning service provider, we use OEM product when specified and document batch numbers so any future claim stays clean. Call (657) 286-7673 if you need help reading your existing warranty language.
We can match most Owens Corning lines from current inventory, including AttiCat, EcoTouch, and FOAMULAR. If a specific product is discontinued, we’ll show you the Owens Corning replacement spec and a compatible alternative from our multi-brand inventory - Reflectix included - with the performance data for each. Estimates are free.
Repair is rarely cost-effective for distributed fiberglass or blown-in product. Spot-repairing settled AttiCat leaves you with inconsistent R-value and no air-sealing benefit. Full removal and replacement with proper air sealing typically pays back in 4-7 years through reduced HVAC runtime in Tustin’s climate. Call (657) 286-7673 for a written comparison on your specific assembly.
Most standard attic jobs finish in one day. Contaminated or vermiculite removal takes two to three days for testing, containment, and disposal scheduling. We don’t start without a written price, and we don’t leave without your Documented Photo Record. Same-week scheduling is usually available.
You get a written R-value report (R-38 in the attic, R-13 in the walls, per scope), before-and-after blower-door readings in CFM50, thermal images, depth verification photos, and your written warranty. This is standard on every job, not available on request. Under Haven Standard, you know what leaving looks like before we arrive.
