Sonex® Valueline Acoustic Foam offers an affordable yet effective means of sound control. The subtle surface pattern on these panels renders them inconspicuous in most settings, making them suitable for a variety of interior settings, including manufacturing facilities, churches, and classrooms. The unique surface pattern absorbs sound and should be used in applications that do not require a pattern match across adjoining pieces. Sonex® Valueline foam maintains a Class 1 fire rating that meets or exceeds most building codes, making it acceptable in virtually any environment where cost-effective acoustical control is needed.
Sonex® Valueline Acoustic Foam is available in numerous colors, including natural grey, natural white, and various HPC coatings. HPC Coatings cover the panel face and edges.

What is HPC coating?
HPC is a high-performance coating that is applied to acoustical melamine foam base. Our exclusive water based HPC formulation improves durability and protects the acoustical foam from dust and dirt, allowing the surface to be cleaned using a damp cloth. The HPC coating is especially appropriate for use high-traffic areas. HPC Premium extends the HPC coating further by offering a line of brilliant colors from which to choose.
Are custom HPC colors available?
Custom HPC colors are available. Popular paint brands may be combined with our exclusive HPC formulation to produce unique designs for any project.
Customers with an order for custom HPC colors will receive a sample to approve prior to producing the order.
