Abstract: A vibration isolating mounting clip which is used to mount a furring channel to a mounting surface, which is then further loaded with a finishing substrate via the furring channel consists of a resilient bent metal strip. The resilient bent metal strip has a first end and an opposing second end, and a transition portion shaped to fit the furring channel. Through different aspects of the invention either the first end, or the first and second end is mounted to the mounting surface. The resilient bent metal strip has a stiffness and shape such that when the furring channel is positioned in the resilient bent metal strip, and the resilient bent metal strip is mounted to the mounting surface, and a finishing substrate is loaded on the furring channel, the furring channel does not contact the mounting surface. Between the ends of the resilient bent metal strip, and the furring channel, are one to several bends, towards and away from the mounting surface to achieve the desired resiliency.

Abstract: A soundproof assembly having front and rear panels with one or both of the front and rear panels having a laminar structure. In one embodiment the front and rear panels are spaced apart by a spacer structure and a covering structure is attached around the periphery to provide an enclosed air space between the front and rear panels. In another embodiment the front and rear panels are affixed to each other. In another embodiment front and rear panels are separated by an interior panel.
