Product Description

Sonex® Mini Acoustic Foam is designed for use in environments where high frequency noise control is required. Its unique sculpted pattern allows for a maximum handling of high frequency sound waves. Sonex® Mini is class 1 fire rated and it is 100% fiber-free foam (part #MSO).

Sonex Mini acoustic foam panels provide our lightest level of sound absorption and are perfect for fine tuning your acoustic space. Minis are our thin and lightweight, perfect for machinery enclosures, restaurants, conference rooms and more!

Featuring the smallest take on the classic Sonex anechoic wedge pattern, Sonex Minis are an exceptional budget choice for noise attenuation. With a Noise Reduction Coefficient (NRC) ranging from 0.50 to 0.65, these open-cell Willtec foam panels convert sound energy into quiet, kinetic energy. All Sonex products are non-toxic, non-flammable, and are Class A/1 fire-rated.

Sonex panels are available in both natural colors and with our High-Performance Coating (HPC). Our exclusive HPC formulation protects the foam from dust and dirt and allows for easy cleaning of the panels with a damp cloth. The panels are easy to install on any wall or ceiling surface with our acouSTIC Adhesive and are easy to cut and shape.
