            |  AcoustiGuard 
              RB is a 'loaded' PVC with a fiberglass scrim center making it 
              an extremely durable and highly flexible acoustic barrier. This 
              1.0 lb. per sq. ft. material is an attractive light silver/grey 
              in color. It is very easy to work with and readily accepts fittings 
              such as grommets or Velcro, making it an excellent choice for curtains 
              or acoustic over-wraps. The surface is easy to clean and contamination 
              resistant, allowing it to be used in nearly any environment.
