Request Information
Art-Composite non-reinforced barrier septum is a flexible vinyl used by itself or in combination with absorptive material as an additive mass treatment for existing equipment enclosures or housings and as a pipe or duct wrap. Art-Composite reinforced vinyl is used in conjunction with grommets and velcro to provide a suspended enclosure for in-plant applications. It is available with quilted or encapsulated fiberglass for added absorption and to meet Class A flammability requirements.

Details

 N/A Art-Composite is a noise control material specifically designed to achieve maximum attenuation over a broad frequency range. Art-Composite combines dense, limp, flexible, non-lead loaded barriers with Acousti-Mat foams providing a total noise control system. Unlike other composites available, these multilayer systems are manufactured without costly adhesives, thus eliminating the potential for failure between layers. Designed by acoustical engineers, Art-Composite has been optimized to economically provide:
  • High transmission loss - the barrier's ability to impede airborne noise.
  • High noise reduction coefficients - the foam's ability to absorb airborne sound energy with minimum reflections.
  • Damping - the composite's ability to attenuate structure-borne vibration on metals and plastics thereby reducing reradiated noise and material fatigue.
The diversity of constructions makes possible engineered solutions for most GEM and in-plant applications. Art-Composite is available with single and double layer septums, various barrier weights, foam thicknesses and a variety of surface treatments. Art-Composite is available in rolls, sheets, die cut or fabricated to customer specifications or can be easily field cut with a knife or scissors. These composites can be adhered to the substrate with factory supplied, economical, SBR pressure sensitive adhesive or an acrylic based pressure sensitive adhesive for temperatures up to 250ºF. It is recommended that a contact adhesive or mechanical fasteners be used for these heavily loaded composites in overhead applications.
