How Knauf Products Fail - and How We Fix Them

• Knauf EcoSeal cavity gaps in pre-2019 installs. The EcoSeal water-based elastomeric sealant was applied in many El Monte tract homes during the 2015-2018 building boom, and it degrades faster in the San Gabriel Valley’s combination of summer heat spikes and winter humidity cycles. We’ve pulled failed EcoSeal from walls in the Mountain View area where the sealant had turned to powder, leaving batt gaps at top plates. We remove the degraded material and re-seal with Knauf’s current formulation or a compatible closed-cell spray application before reinstalling.
• Knauf Insulation Jet Stream Ultra settling in 2×4 walls. This blown-in fiberglass was marketed for wall retrofit via dense-pack, but in El Monte’s older homes with irregular stud bays - common in the neighborhoods north of Valley Boulevard - the material settles away from the top plate within 3-5 years. We diagnose this with a borescope inspection through a discrete wall port, then extract and repack with correct density or switch to a stabilized cellulose blend if the cavity geometry won’t hold fiberglass.
• Knauf Momentum HD facing delamination in garage-to-conditioned-space walls. The kraft facing on this high-density batt separates from the fiberglass core when subjected to the temperature differential typical of El Monte garage walls, where summer surface temps hit 110°F on the garage side while conditioned space stays at 72°F. We replace with unfaced Momentum HD and add a separate vapor retarder sized for the actual climate zone, not the generic California specification.
• Knauf Ecobatt corrosion in contact with galvanized steel studs. The plant-based binder in Ecobatt holds moisture longer than synthetic binders when installed against steel framing in commercial conversions near the I-10 corridor. We’ve found rust-jacketed steel studs in three El Monte mixed-use retrofits where Ecobatt had been specified for its green credentials. We extract the affected batts, treat the steel, and specify a mineral wool alternative or Knauf’s standard fiberglass with synthetic binder for that application.
• Knauf blow-in blanket system (BIBS) netting failure in balloon-framed walls. The poly netting that holds BIBS fiberglass in open wall cavities degrades with UV exposure if any gap in the exterior cladding admits daylight - a real issue in El Monte’s 1950s ranch stock with original stucco cracks. We remove the failed netting and material, then reinstall using a current-generation netting with UV stabilizers or convert to a dense-pack approach if the wall sheathing condition allows.

Our Knauf Wall Insulation Process

1. 1
   Call and scope. A live person answers, schedules a site visit, and sends a text confirmation with your technician’s name. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way.
2. 2
   Blower-door test and thermal imaging. We pressurize the house to measure total envelope leakage (the blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing), then use infrared to locate where Knauf product has failed or where walls were never properly sealed at top plates.
3. 3
   Written price and material specification. We specify exact Knauf product lines or cross-compatible alternatives, with OEM-versus-aftermarket decisions documented. No work starts without a flat price, written scope, and written warranty delivered.
4. 4
   Air sealing first, then insulation. Seal the bypasses first. Then insulate. The certificate tells you what you actually got. We seal all top plates, electrical penetrations, and plumbing chases before any new Knauf material goes in.
5. 5
   Installation with depth verification. Blown-in depths are checked with depth rods; batt installations are photographed in place. The crew documents R-value achieved, not just product specified.
6. 6
   Final blower-door test and documentation. We run the pressurization test again, publish the before-and-after numbers, and leave a printed R-value certificate plus photo record on-site before the truck leaves.
