CelluZorbe™ Cellulose Acoustic Panels
CelluZorbe is an environment and budget-friendly acoustical panel that doubles as thermal and sound insulation. Made primarily of recycled newspaper, this soundproof insulation is a common alternative to mineral wool insulation and fiberglass 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!
Features
- Cellulose-based acoustic materials are environmentally friendly and excellent for sound absorption and thermal insulation
- Completely recyclable, with no scrap produced during manufacturing or installation
- Made from renewable and recycled fibers (90% recycled content, post-consumer paper)
- Resists mold and fungal growth
- Class A Fire Rated
- Easy to handle and install
- Proudly made in the USA

Installation Instructions
Installation 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.
