HUSH WRAP™ composite products combine a layer of HUSH BLOCK™ type LV-100-LAG with a layer of type QAB HUSH QUILT™ absorber blanket. The QAB layer is applied to the source and acts as an absorber and more importantly as a spacer or decoupler for the flexible barrier layer. The decoupling or floating of the HUSH BLOCK™ barrier helps achieve greater noise reductions than if the barrier was attached directly to the noise emitting surface. The biggest advantage of HUSH WRAP™ composites is the easy one-step installation of both decoupler and barrier layers thus offering substantially lower installation costs compared with built-up systems. Matching trim tape can be used to seal all seams and edges. This family of composites can usually be installed by factory personnel. Acoustic performance data is listed below.
