Acoustic perforated structural liner tray

RoofDek acoustic structural liner trays provide a neat planar inner surface and structurally support the external envelope. RoofDek acoustic structural liner trays offer a wider flat soffit enabling a greater perforated area, achieving the best acoustic absorption result. The percentage of exposed area is the open area divided by the exposed area of steel following around the profiles. The percentage of cover area is the open area divided by the plan area of the soffit.
