Note

Note

 N/A Sound energy, passing through the cell structure, is converted into minute quantities of low grade heat that is easily dissipated. Since the uniformity of the cells are carefully controlled the efficiency is constant and predictable from one installation to another.

Many applications require these products to be subjected to environments such as dirt, moisture, chemicals and abrasion that could be hostile to an unprotected foam. ArtUSA® industries has developed various surface treatments to protect the integrity of the foam from these elements. These facings will increase the absorption properties at certain frequencies as well as provide a cleanable, decorative and durable finish for a wide variety of applications.

Art-Mat foams can be purchased in rolls or sheets and can be die cut or fabricated to customer specifications. They are easily cut with a knife, saw or scissors. The addition of pressure sensitive adhesive provides a convenient method of fastening to most substrates. All Art-Mat products can be made in combination with Art-Composite barrier systems when both absorption and transmission loss is needed or VETM damping systems, when enhanced vibration control is required.
