How Knauf Products Fail - and How We Fix Them

We’ve pulled enough Knauf out of Pflugerville walls to know the failure patterns by series. Here are the five we see most often:

• Knauf EcoSeal cavity sealant pulling away from top plates in 2018-2021 builds. The water-based acrylic doesn’t bond well to dusty OSB in Central Texas dry spells, and once the sealant gap opens, blown-in Jet Stream Ultra behind it acts like a filter, not a barrier. We remove the compromised fill, re-seal with a compatible acrylic-urethane hybrid, then re-blow to density.
• Jet Stream Ultra settling below electrical outlets in two-story homes. The ultrafine fiberglass compresses over 3-5 years where wiring penetrations disrupt the cavity, creating a cold stripe at outlet height that homeowners feel in February. We dense-pack the lower cavity with new Jet Stream or switch to a stabilized cellulose if the homeowner wants a different material.
• Knauf Insulation Board (KIB) faced batts wicking moisture at rim joists. The kraft facing fails when Pflugerville’s spring humidity hits 80% and the rim joist lacks a proper air barrier. We pull the wet batts, treat any rim-joist mold with a borate solution, seal with closed-cell foam or a smart vapor retarder, then reinstall with an unfaced product and mechanical fastening.
• Ecobatt with ECOSE Technology losing binder adhesion in south-facing walls. The plant-based binder breaks down faster under thermal cycling above 140°F surface temperature, which happens regularly on Pflugerville’s west and south exposures from June through September. We remove the degraded batts and recommend a mineral wool or dense-pack replacement for those walls.
• Knafi ll insulation (the loose-fill product) bridging around obstructions instead of filling. Installers without wall-cavity experience blow it like attic fill, leaving voids behind fire blocks and at stud bays interrupted by plumbing. We use a tube-fill method with cavity-by-cavity verification, or switch to injection foam for complex framing.

Our Knauf Wall Insulation Process

1. 1
   Call and scope. A live person answers, schedules a site visit, and Wes Okafor or a senior tech arrives with a borescope and moisture meter.
2. 2
   Diagnostics and blower-door test. We run a pressurization reading - CFM50 - to quantify how much air the wall assembly is losing before we open anything. The report tells you what the house does. The insulation changes what the house does. Those are two different conversations.
3. 3
   Written price and material spec. We specify Knauf, Reflectix, or another material based on what the cavity needs, not what we have in the truck. You get a flat price and written scope before anyone lifts a tool - Haven Standard Clause 1.
4. 4
   Air sealing first, then insulation. Top plates, electrical penetrations, and any rim-joist gaps get sealed before new fill goes in. We don’t blow over leaks.
5. 5
   Install with density verification. For drill-and-fill, we check every cavity with a fill tube and resistance measurement. For batts, we inspect for compression gaps and vapor-retarder continuity.
6. 6
   Post-job blower-door test and documentation. New CFM50 number, photo record of the work, and written warranty delivered before we leave. Most jobs finish in one day.
