How Owens Corning Products Fail - and How We Fix Them
- Owens Corning AttiCat blown-in fiberglass settles below labeled R-value in compacted attic floors. The pink loose-fill compresses under foot traffic during prior service work or rodent activity, creating thin spots that read fine on visual inspection but fail in a thermal image. We remove compromised batts, air-seal every top plate and penetration with fire-rated caulk and rigid baffles, then reinstall to proper depth with a density check.
- Owens Corning FOAMULAR XPS rigid foam boards delaminate at the foil facing in Mountain View’s marine climate. The high humidity and temperature swings in crawl spaces near Stevens Creek cause the reflective layer to bubble and separate, creating a vapor trap. We pull the damaged boards, assess the subfloor for moisture damage, and replace with properly taped seams and a compatible vapor barrier strategy.
- Owens Corning EcoTouch batts installed without air sealing create a “wind-washing” effect at eaves. Air moving through soffit vents blows directly across the fiberglass surface, stripping away its effective R-value in winter. We install proper vent baffles - cardboard or foam, depending on roof pitch - then seal the plate line before re-insulating.
- Owens Corning ProPink Loosefill L77 shows thermal bypass at recessed can lights in pre-2015 Mountain View builds. The fill packs against non-IC-rated fixtures, creating both a fire hazard and a convection loop. We box out each fixture with fire-rated covers, seal with high-temp caulk, then reinsulate around the enclosure.
- Owens Corning duct board in original 1960s-1980s Peninsula tract homes crumbles at the foil-reinforced edges. The fiberglass mat separates from the airstream surface, dumping conditioned air into the attic. We map the leakage with a duct blaster, replace failed sections with sealed flex or hard pipe as appropriate, and verify with a post-repair pressure test.
Our Owens Corning Home Energy Audit Process
- 1
Call and schedule. A live person answers 24/7. We book a 2-hour arrival window and text you when the technician is en route.
- 2
Visual and thermal inspection. We walk the attic, crawl space, and duct runs with a FLIR camera, looking for Owens Corning-specific installation errors: compressed AttiCat, delaminated FOAMULAR, missing baffles.
- 3
Blower-door test. We depressurize the house to 50 pascals and record the CFM50 reading - the single number that tells us how much conditioned air is escaping.
- 4
Written scope and price. Before any work starts, you get a flat price, a written scope, and the Haven Standard warranty. No exceptions.
- 5
Air sealing first, then insulation. We seal every penetration at the attic floor before a single pound of new material goes in. Seal the leaks first. The insulation has nowhere to go if the air does.
- 6
Post-job verification and documentation. We run the blower door again, hand you the before-and-after numbers, and leave a photo record of every sealed location.

The 365-Day Done Right Promise applies to all work, and we also service Reflectix radiant barrier systems when that’s what your assembly calls for. Materials come from Owens Corning, Johns Manville, Knauf, and others - no proprietary lock-in, just what performs for your specific envelope.
FAQs
No. Product warranties cover manufacturing defects, not diagnostic work. As an independent Owens Corning service provider, we document existing conditions with photos so any future warranty claim has a clear baseline. If we find a manufacturing issue during audit, we flag it and advise you on OEM claim procedures. Call (669) 259-0406 to schedule.
We use OEM Owens Corning materials when the original specification is still viable and cost-effective. For discontinued lines or applications where a different product performs better - FOAMULAR replacement in high-moisture crawl spaces, for example - we specify compatible alternatives from Johns Manville or Knauf and explain the trade-off in writing before you decide.
Repair is cheaper when the material is dry, uncompressed, and properly installed - roughly 30-40% less than full replacement. Replacement is the better value when we find moisture damage, rodent contamination, or installation errors like blocked soffit vents that compromise the entire assembly. We tell you which category you’re in during the free estimate, with photos. Call (669) 259-0406 for an exact quote.
Most audits happen within 48 hours of your call, and the on-site work takes 2-3 hours. Same-day scheduling is often available Tuesday through Thursday. We text your technician’s name and ETA the morning of.
You get a written scope with flat pricing, thermal images with temperature readings, the blower-door printout showing CFM50 before and after any sealing work, and a photo record of every location we addressed. This is standard on every job, not available on request.
