 About BRD HUSH QUILT™ Composites:

Dual layer construction combines absorber layers to dissipate acoustic energy at the source with a flexible vinyl sound barrier to block and contain sound transmission traveling to adjacent areas or spaces.  Sound waves originating from the source will be initially absorbed by the absorber layer and then reflected by the flexible barrier resulting in further dissipation.          Type BAC composites shown at right below are best utilized for maximum durability and where a noise source(s) are located on one side of the acoustical material.  Type ABAC composites (see below left) are recommended for multiple noise sourcces on both sides of the materials, where a greater amount of noise reduction is required or where it is used as an internal liner on any rigid surface.

Notes: When ordering roll goods:

1) Acoustical testing per ASTM C-423-77, C-423-90A, ASTM E-90-75; E-90-90.  Copies available upon request.

2) Flame spread and smoke density ratings are per ASTM designation E-84 (surface burning characteristics of building materials).  Select products meet ASTM E-162 flame spread and E-662 smoke density criteria.

Standard HUSH QUILT™ roll goods are all furnished with unbound edges.  Purchase orders not specifically requesting stitch edge binding will be processed as unbound material.  Standard roll good material may be returned in unused condition subject ot a 35% re-stock charge upon receipt of a return material authorization (RMA) from BRD.
