Echo Absorber Acoustic Panel (Natural Blend – 1″x2’x4′)




Echo Absorber acoustic paneling is one of our most cost-effective soundproofing solutions. However, at Soundproof Cow, affordable doesn’t have to mean cheap — Echo Absorber™ panels offer exceptional quality at a reasonable price point, making them perfect for DIY applications or for anyone else who wants to make the best use of their budget.

A Natural Alternative

Echo Absorber natural blend paneling is made from genuine cotton fibers, as much as 80% of which are recycled. It contains no VOCs or hazardous materials and has a Class A fireproof rating. As a result, it can be installed in locations where strict building code requirements prohibit the use of polyurethane or other synthetic materials.

Superior Performance in a Lightweight Package

Echo Absorber acoustic panels are more than just environmentally friendly — they’re also one of our best soundproofing materials. Use them to deaden recording spaces and prevent outside noise from bleeding in. Echo Absorber panels are also highly effective at absorbing nuisance reflections that cause poor sound quality.

Working with our product is easy. Echo Absorber acoustic panels can be glued to any flat surface using our PL® Construction Adhesive. Alternately, install them inside a wall for soundproofing purposes. As an added bonus, they also provide excellent thermal insulation properties, making your space more comfortable and even potentially lowering your utility bills.

Ideal for Home and Professional Use

Use Echo Absorber acoustic panels to reduce harsh reflections in offices, classrooms or other spaces. Contact one of Soundproof Cow’s resident experts to learn more.

Echo Absorber™ Acoustic Panel Install

I need something quick and easy to put in a generator enclosure, so I went with the Echo Absorber Natural. It ain’t pretty but it works great. As soon as I lined the interior and put it over the generator it was like a whole different world. I’ll be using this a lot more now that I know how great it works. Make sure you talk to Jim, he was really helpful.
