Convoluted Acoustic Foam Panels are manufactured from acoustic grade polyurethane foam, in an “egg crate” design, which provides an increased surface area, giving you better sound absorption performance. The material is flexible and easy to cut. Convoluted Acoustic Foam Panels are a cost effective solution for improving sound absorption by reducing echo and reverberation. Convoluted Acoustic Foam Panels aren’t just for recording environments, they can be used in equipment and machine enclosures to reduce vibration and airborne noise propagation. This product is perfect for any application where acoustics are poor and budgets are tight. Convoluted Acoustic Foam Panels have a UL94 HF-1 flammability rating and are availabel in charcoal only.

Good Sound Absorption Characteristics — The convoluted or “egg-crate” design increases surface area, giving you better sound absorption performance. Convoluted Acoustic Foam Panels absorb sound generated at low, mid and high frequencies, making them perfect for recording or listening environments.
Quality — Convoluted Acoustic Foam Panels are made with flexible, professional grade acoustic polyurethane foam. The foam is consistent in density and firmness so, sound absorption performance will also be consistent.
Value — Convoluted Acoustic Foam Panels are our most cost effective, studio grade sound absorption product. They are high performance sound absorption acoustic panels at a great price.
Ease of Installation — Convoluted Acoustic Foam Panels are lightweight and can be attached to a variety of surfaces. No special tools or materials are needed for installation.
Fiber Free — Convoluted Acoustic Foam Panels are safe to use in clean room, medical and computer equipment environments.
Flammability — Convoluted Acoustic Foam Panels are manufactured from polyurethane foam that has a flammability rating of UL94 HF-1. Before choosing this product, be sure the flammability rating passes your local building code for exposed materials.

Proper acoustics are essential in a recording studio. If just one decibel of sound bounces off any untreated surface, it could mean the difference between a marginal or high quality recording and one that turns into an expensive project that needs to be redone. Our value-priced Convoluted Acoustic Foam Panels are a good solution for your recording studio. Whether you’re a hobbyist, or a professional committed to producing first-class results, our Convoluted Acoustic Foam Panels will save you the time of having to redo a track because of background noise.

All Polyurethane Foams, including Combustion Modified Foams, will burn. Do not expose to any flame source. Once ignited, they can produce rapid flame spread, intense heat, dense smoke and toxic gases causing death. Warnings should be given to your employees and or customers. Test data does not necessarily reflect a foams performance under actual fire conditions. Before purchasing any foam, be sure to check with your local code officials to confirm the required flammability rating of exposed materials for your area.
Tools Needed: Tape measure, Level, Pencil
Materials Needed: PL Construction Adhesive or Clearco 444 Spray Adhesive, and caulk gun
