How Owens Corning Products Fail - and How We Fix Them

• Fiberglas Pink Insulation (batts and blown-in) settling below labeled R-value in La Habra’s dry heat. Owens Corning loose-fill Fiberglas tends to settle 10-15% faster than cellulose in attics that see repeated 100°F+ days, which La Habra gets 20-30 times per year. The labeled R-38 becomes an effective R-30 or lower. We pull settled material, air-seal the deck, then supplement with open-cell spray foam to restore and exceed the original thermal target.
• AttiCat blown-in system creating thermal bypasses around chases and top plates. The AttiCat machine blows fast, and in the hands of a rushed installer, it bridges over gaps instead of filling them. We find this constantly in La Habra tract homes from the 1970s and 1980s near Imperial Highway. Our fix: remove the bridge, seal the bypass with closed-cell foam at the top plate, then reinstall blown-in or transition to spray foam at the roof deck.
• FOAMULAR rigid board delaminating from garage ceiling assemblies. Owens Corning FOAMULAR XPS, common in La Habra garage ceiling retrofits, can pull away from the substrate when the facing adhesive fails in summer heat cycling. The gap becomes a convection channel. We remove the failed board, reattach with proper fasteners and compatible adhesive, then seal the perimeter with closed-cell spray foam for a monolithic air barrier.
• QuietZone acoustic batts compressed during storage or install, killing both R-value and sound performance. QuietZone is specified for interior walls and floor assemblies; when it’s compressed into a 2×4 cavity meant for standard batts, the R-value drops from R-13 to roughly R-9 and the acoustic benefit is gone. We see this in La Habra townhomes near Beach Boulevard. We pull the compressed material, verify the cavity depth, and specify either proper-dimension batts or open-cell spray foam for both thermal and acoustic performance.
• ProPink High-Performance blowing wool leaving attic hatches and kneewalls unaddressed. ProPink is a solid product, but the system warranty only covers the material itself - not whether it was installed with continuous coverage. We regularly find La Habra homes where the main attic got 14 inches and the kneewall got 3 inches because the installer ran short. We treat kneewalls and hatches as separate assemblies, often using spray foam for the complex geometry where blown-in won’t hold position.

Our Owens Corning Spray Foam Insulation Process

1. 1
   Call and scope. A live person answers (562) 267-3291 24/7. We schedule a site visit, not a phone estimate.
2. 2
   Diagnostics and blower-door test. We pressurize the house to measure CFM50 - the single number that tells us how much conditioned air is escaping. In La Habra’s older ranch homes near the La Habra Heights border, we almost always find attic bypasses unsealed on the first pass from prior work.
3. 3
   Written price and material spec. You get a flat price, written scope, and written warranty before anyone lifts a tool. Haven Standard Clause 1. We specify Owens Corning where it fits the assembly, or we recommend spray foam from Icynene, Demilec, or Johns Manville if the application demands it - no proprietary lock-in.
4. 4
   Air sealing first, then insulation. Seal the bypasses first. The insulation has nowhere useful to go until the air does. Top plates, can lights, plumbing penetrations, and chimney chases get sealed before a single board or bag goes in.
5. 5
   Spray foam installation and real-time verification. We monitor substrate temperature, ambient humidity, and pass thickness during application. Closed-cell gets installed in lifts to prevent shrinkage; open-cell gets trimmed flush for drywall or left exposed per assembly spec.
6. 6
   Post-work blower-door test, photo record, and documentation. We run the blower door again and hand you the before-and-after numbers. You also get the Documented Photo Record and settled-depth measurements at four attic quadrants. Every time.
