Our AlphaFlat™ Foam provides acoustic absorption for applications seeking a flat, smooth appearance with no pattern. AlphaFlat foam is available in 2′ x 4′ sheets and in a range of thicknesses. Consisting of a lightweight, Class 1 fire rated acoustical core, this foam may be used in a wide range of applications. AlphaFlat foam is easy to cut and installs with construction adhesive.

AlphaFlat™ Foam delivers a versatile wall and ceiling panel for use in applications like offices and recording studios, as well as in tougher industrial applications. The fiber-free core makes this an excellent acoustical substrate to absorb sound in a multitude of systems, including fabric track stretch wall systems.

    I used this as a sound dampening barrier around an aluminum saw by sandwiching it between formed pieces of 14 ga. stainless steel and completely enclosing the saw. The foam worked great and is of a good quality.

What is the difference between AlphaFlat Foam and Sonex® Willtec Flat Foam?

AlphaFlat and Sonex® Willtec Flat foams are made from a similar melamine acoustical core with equivalent acoustical properties.  AlphaFlat is available in a range of thicknesses from 1″ to 4″ with a standard sheet size of 2’x4′, where as the Sonex Willtec is available in thicknesses of 1/2″ to 2″ with standard sheet sizes of  2’x2′, 2’x4′, 4’x4′, and 4’x8′. 

The AlphaFlat foam has a similar color selection, and the AlphaFlat offers a charcoal color. If a cleanable, durable surface is required, Sonex® Willtec may be custom coated with HPC coatings. If necessary, either of these two products may be ordered in custom sizes and configurations for OEM applications or special projects.
