Echo Absorber Acoustic Panel 2″ (Case of 3)




Our 2” thick Echo Absorber paneling can be used to soundproof a wide range of spaces, from home and professional recording studios to manufacturing facilities and other industries sites. In any application, Echo Absorber panels can be counted on for exceptional low- and high-frequency noise reduction at an affordable price point.

Now Available in Convenient Three-Packs

2” Echo Absorber panels are among our best-selling high- and low-frequency noise reduction products. Purchase them in a convenient three-pack to quickly turn around any project. Individual panels measure 2’ by 4’ — a single pack provides enough paneling to cover up to 24 square feet. Install them on any flat surface, including cement, wood or drywall.

A Natural Alternative to Synthetic Soundproofing

Echo Absorber products are made from natural cotton fibers, up to 80% of which are recycled. Lightweight yet dense, they are ideal for soundproofing low-frequency noise and can be counted on to deliver performance equal to that of comparable polyurethane products. They are also naturally resistant to mold and mildew and are rated for Class A fire resistance.

Echo Absorber panels are highly durable and dent-resistant and, unlike fiberglass, they won’t irritate the skin when touched. As a result, they’re a great choice for tight studio environments where collisions are not uncommon.
