Fabricmate® Acoustic Cotton is an eco-friendly alternative to fiberglass or mineral wool acoustic insulation. Safe and easy to handle, it is made from 100% post-industrial denim and cotton fibers. High-quality and sustainable building materials such as these are great for every project whether it’s LEED certified or just that DIY you’ve been considering.

Acoustic Cotton provides incredible acoustic absorption and thermal performance without the chemical or fiberous irritants found in other forms of acoustic insulation. It comes in 1/4″, 1/2″, 1″ & 2″ thicknesses, making it an excellent acoustic backing for use with all of our acoustic Stretched-Fabric Systems.

The unique manufacturing of Acoustical Cotton allows it to trap and absorb sound waves, which greatly reduces reverberated sound. Having a Noise Reduction Coefficient up to 1.05 (at 2″ thickness) makes it an ideal material for many applications, such as in home theaters, conference rooms, classrooms and other high-traffic enviornments.
