CelluZorbe™ Cellulose Acoustic Panels

CelluZorbe is an environment and budget-friendly acoustical panel that doubles as thermal and sound insulation.

These cheap acoustic panels are a truly flexible solution. They're great as an itch-free core for DIY acoustic panels, and for use as hidden absorption or as value sustainability when solving sound and heat problems!

Install Instructions

Recommended Adhesive: P329 Spray Adhesive

  • Place the CelluZorbe™ panel on the wall. Make a horizontal and vertical line along the edge of the panel using a level, intersecting at one corner.
  • The P329 Spray Adhesive is an aggressive, pressure sensitive adhesive designed for PERMANENT bonding of our acoustical panels to a drywall, metal, concrete, or wood substrate.
  • Apply spray adhesive to both the material and the substrate with 80 to 100% coverage. To avoid overspray, a small gap around the edge is not a problem.
  • Allow 2-4 minutes for the spray adhesive to tack up.
  • Press the material and substrate together with as much pressure as practical. The initial bond is very strong, but maximum strength is achieved in 1-3 days.
  • These steps can be found in our CelluZorbe™ P329 Spray Adhesive Install Guide.

If buying adhesive locally, we recommend a combination of construction adhesive (Loctite Power Grab or equivalent) and spray adhesive (3M Super 77 or equivalent). See our CelluZorbe™ Install Guide (Construction Adhesive) for instructions.
