How Knauf Products Fail - and How We Fix Them

• Jet Stream Ultra settling in 2×4 exterior walls. This blown-in fiberglass is designed to achieve R-15 at full loft, but in Round Rock’s clay-heavy soils and the resulting wall settling common in Behrens Ranch and Forest Creek builds from 2012-2019, we’ve measured Jet Stream Ultra compacted to R-9 or below. We extract the collapsed material with a vacuum truck, air-seal the top plates and electrical penetrations we expose, then reinstall to specified density with fresh Jet Stream or an equivalent blown fiberglass.
• EcoFill WX gaps at stud bays with horizontal blocking. Knauf’s stabilized cellulose performs well when it contacts all six sides of a cavity, but Round Rock framers often install fire blocking mid-height in two-story walls. EcoFill misses the narrow gap above and below these blocks, creating thermal bypasses. We drill additional access holes at blocking height, fill the voids completely, and document with endoscopic photos.
• Jet Stream MAX over-densification from improper installation. Some crews in Williamson County have run this product at too high a hose pressure, fracturing the fiberglass and reducing its effective R-value by 15-20%. We test sample cores from existing walls; if the material is powdery rather than fibrous, we remove it and reinstall at Knauf’s specified 0.6-0.8 pounds per cubic foot.
• Knauf cavity wall insulation wetting from exterior moisture intrusion. In Round Rock’s sudden spring downpours, failed window flashing or stucco cracks send water into walls. Jet Stream and EcoFill both lose R-value when damp - cellulose especially sags and molds. We locate the moisture source, allow full drying (documented with moisture meter readings), repair the envelope breach, then replace only the affected insulation.
• EcoFill settling in vaulted ceiling walls. The angled top plates in Round Rock’s popular cathedral-ceiling additions create a gravity-driven compression zone. EcoFill installed from below slumps toward the eaves over 3-5 years. We access from the ridge vent when possible, install rigid baffles to maintain the ventilation channel, then dense-pack fresh EcoFill or switch to Jet Stream Ultra where slope exceeds 45 degrees.

Our Knauf Wall Insulation Process

1. 1
   Call and schedule. A live person answers - no voicemail loop. We book a diagnostic visit, usually within 24-48 hours in Round Rock.
2. 2
   Blower-door test and thermal imaging. We pressurize the house and run an infrared camera to locate where Knauf insulation has failed, settled, or was never properly installed. You get the CFM50 number before we touch anything.
3. 3
   Written scope and price. We specify: Knauf product line or approved equivalent, wall square footage, access method (interior drill-and-fill or exterior siding removal), air-sealing details, and cleanup protocol. The price is flat. No work starts without your signature.
4. 4
   Air sealing first. Seal the leaks first. The insulation has nowhere to go until you do. We seal top plates, electrical boxes, and penetrations with fire-rated caulk and foam before any insulation enters the wall.
5. 5
   Knauf installation or repair. We install to manufacturer density specs using calibrated equipment, or we extract and replace failed material. OEM Knauf products or quality equivalents from our multi-brand inventory - we carry Owens Corning, Johns Manville, Rockwool, and others, so we’re never locked into one supplier if Knauf lead times stretch.
6. 6
   Post-install verification and documentation. Second blower-door test on applicable jobs, photo record of every wall cavity, written completion certificate with your warranty terms. You keep the folder; we keep the backup.
