Product Description

Our AlphaSorb® Flat Acoustic Foam provides acoustic absorption for applications seeking a flat, smooth appearance with no pattern. AlphaSorb® Flat Acoustic Foam is available in in a range of sizes and thicknesses. Consisting of a lightweight, acoustical foam core, these panels can be used in just about any direct mount wall or ceiling application. Flat acoustic foam is a great choice for projects that require form fitting absorption. Its melamine acoustic foam core trims easily using a smooth blade utility knife and installs with a foam construction adhesive.

AlphaSorb® Flat Foam delivers a versatile foam panel for use in open offices, recording studios, lobbies, as well as in tougher industrial applications. You can create interesting dimensional patterns by utilizing the various thicknesses of this foam.The fiber-free core makes this an excellent acoustical substrate to absorb sound in a multitude of systems, including fabric track stretch wall systems. There is no itchy fiberglass to cut or clean up. Similarly, use AlphaSorb® Flat Acoustic Foam to line noisy enclosures like HVAC ducting, speaker boxes or machine housings.
