Quilted Fiberglass Sound Absorption

Features

• Maximum noise reduction by combining sound absorber and noise barrier

• Sound Absorption Rating to NRC-1.05

• Transmission Loss Rating to STC-32

• Offered in two styles with a variety of combinations

• Acoustical liners, jackets, wraps and panels
• Available in curtain panels, bound or unbound rolls, custom fabrications or die-cut pieces
• Flexible composites conform to any shape
• Fire safe and low smoke emissions per ASTM E-84, Class 1

"BSC" Style: Barrier Septum Composite

"BSC" composite features a non-reinforced loaded vinyl noise barrier septum (right) with a quilted fiberglass sound absorber on both sides. Ideally suited as an acoustical liner, the inner layer of quilted fiberglass decouples the barrier from the surface to improve its noise blocking ability while the outer layer adds sound absorption to the treated environment.

Also Available As:

  • Rolls with edges bound and sewn with matching edge binding
  • Unbound rolls-edges exposed
  • Standard roll size 4' W x 25' L
  • Curtain panels with grommets at top and hook & loop fasteners sewn along edges
  • Liner panels with bound edges
  • Die-cut pieces, custom fabrications

Types of facing material on quilted fiberglass:

  • VCFC: Vinyl - Coated - Fiberglass - Cloth
  • SCFC: Silicone - Coated - Fiberglass - Cloth
  • NPS: Non-Woven - Porous Scrim
  • GUILFORD: Decorative Fabric

Available Barriers:

  • BSC products utilize a flexible 1 lb. PSF non-reinforced loaded vinyl noise barrier septum (B-10NR).
  • Also available with a 2 lb. PSF or 1/2 ob. PSF barrier

"BBC" Style: Barrier Backed Composite

"BBC" composite features a reinforced loaded vinyl noise barrier with a quilted fiberglass sound absorber on one side. The rugged durable exterior barrier is commonly used as a wrap or acoustical jacket due to its ability to conform to any shape. The quilted fiberglass layer decouples the noise barrier to enhance its acoustical performance.

Also available as:
• Rolls with edges bound and sewn with matching edge binding
• Unbound rolls with quilted fiberglass edges exposed
• Standard roll size 54" wide barrier, with 48" wide quilt, 25' long
• Curtain panels with grommets at top and hook & loop fasteners sewn along edges
• Custom fabricated acoustical jackets
• Die-cut pieces
• Barrier

BBC products utilize a flexible 1 lb. PSF center reinforced barrier back (B-10R). Available in standard gray color. Tan and light blue are also available. 2 lb. PSF and 1/2 lb. PSF reinforced barriers are optional.
