This page is for homeowners who already have Knauf insulation in their attics or walls and need top-up, replacement, or correction of a previous install gone wrong. If you’re researching blown-in options and Knauf is on your list, here’s what we’ve learned running jobs across Cedar Park since 2016.

How Knauf Products Fail - and How We Fix Them

• Knauf Jet Stream Ultra settling in cathedral ceilings. This high-velocity fiberglass is designed to reach deep cavities, but in Cedar Park’s cooling-dominated climate it can settle 15-20% in the first three years when blown over unsealed top plates. We find it pooled at the low points of vaulted ceilings in Ranch at Brushy Creek homes. Our fix: pull back the settled material, seal every top plate and electrical penetration with fire-rated caulk and gasketed covers, then re-blow to manufacturer density with a depth marker string.
• Knauf Insulsafe SP moisture absorption in vented attics. This stabilized cellulose contains a dry adhesive that activates with moisture, but in Cedar Park’s spring humidity spikes it can clump near soffit vents where bathroom exhaust fans terminate in the attic. We’ve pulled basketball-sized clumps out of attics in Buttercup Creek. Our fix: redirect or extend the exhaust duct to proper termination, verify soffit vent baffles are in place, then spot-remove clumped material and re-blow with corrected ventilation.
• Knauf Ecobatt friction-fit failure in kneewalls. Homeowners sometimes assume batt and blown-in are interchangeable; we’ve found Ecobatt batts stuffed into kneewall cavities that were clearly meant for dense-pack, creating gaps at the studs where Cedar Park’s 105°F attic air pours through. Our fix: remove the incorrectly fitted batts, install proper netting, then dense-pack with Knauf’s recommended wall-density setting.
• Knauf Jet Stream Ultra density inconsistencies from untrained installers. The machine settings for this product are unforgiving; we’ve tested attics in Cedar Park’s newer subdivisions where coverage was 25% below labeled R-value because the installer ran the hose too fast. Our fix: core sample testing with a calibrated scale, mark deficient areas, and re-blow to 0.6 pounds per square foot minimum with a written density log.
• Knauf insulation compromised by rodent activity. Fiberglass and cellulose alike become nesting material; we regularly find Cedar Park attics where raccoons or roof rats have tunneled through Knauf products, compressing channels that destroy thermal performance. Our fix: remove contaminated material per Texas Department of State Health Services guidelines, seal all entry points with steel mesh, then re-install with a photo-documented clean start.

Our Knauf Blown-In Insulation Process

1. 1
   Pre-install blower-door test. We pressurize the house and measure CFM50 - the airflow at 50 pascals of pressure - to establish a baseline. In Cedar Park’s 1990s-built homes, we typically see 3,500 to 5,500 CFM50 before any work begins.
2. 2
   Written scope and price. Under Haven Standard Clause 1, you get a flat price, written scope, and written warranty before anyone lifts a tool. No exceptions.
3. 3
   Air sealing first. Seal the leaks first. Then insulate. The order matters more than the product. We seal top plates, can lights, chimney chases, and all penetrations with fire-rated materials.
4. 4
   Knauf material selection and install. We match the Knauf line to your cavity type - Jet Stream Ultra for open attics, Insulsafe SP for dense-pack walls - and verify machine settings against the manufacturer’s current specification sheet. We do not use generic settings across brands.
5. 5
   Post-install verification. We core-sample for density, run a second blower-door test, and publish the before-and-after numbers. You walk away with a Documented Photo Record and the ACH50 comparison.
6. 6
   Cleanup and 365-Day Done Right Promise activation. The crew vacuums the work path, removes all debris, and leaves the written warranty and photo record. If anything’s not right, we make it right.

Why Cedar Park Homeowners Call Topside Attic Insulation Cedar Park for Knauf Work

We’ve sealed and insulated over 9,000 homes since 2016, and the ones in Cedar Park taught us something specific: the combination of hard freeze winters and 140°F attic summers here means insulation that performs in theory often fails in practice. Wes Okafor, who runs our crews, brought blower-door discipline from Chicago’s building science program and applies it to every Knauf job - no insulation goes in until the air sealing is verified.

We publish before-and-after blower-door numbers on every applicable job. We carry Knauf, Owens Corning, Johns Manville, Rockwool, and Reflectix, so if a different material suits your cavity better, we’ll say so. Our technicians are background-checked and uniformed; calls are answered by a live person 24/7. The 365-Day Done Right Promise applies to all completed work, and every job closes with a Documented Photo Record.
