About BRD HUSH LAG™ Panel Systems: BRD HUSH LAG™ acoustical lagging panels and systems have prefabricated customized multi-layer composite construction. Composite panel designs utilize absorptive and barrier components to achieve the highest possible noise reduction in a direct attachment source treatment. The typical panel construction (shown at right) utilizes a steel or aluminum outer skin for strength and durability. High density acoustic fill may include a layer of HUSH BLOCK™ flexible barrier material for added transmission loss. The inside retaining screen and impaling clips hold the insulation layers in place. Typical panel thickness ranges from 2” to 6” depending on the acoustical performance criteria.Structural steel angle or channel sub-girts are welded to the equipment or ductwork skin with a minimal number of attachment points to reduce structure-borne noise that can radiate to the panel outer skin. Sheet metal screws or other anchors are used to attach HUSH LAG™ panels to the sub-girts. Final installation of flashing and trim at corners and joints covers all exposed fiberglass and edges. Access doors and removable panel sections can be incorporated. |
