Acoustic isolator clip for isolating wallboard support channels from frame member

A sound isolation assembly for use in acoustically isolating wallboard panels from an underlying frame member, comprising:

• at least one elongate resilient channel having at least one attachment edge and at least one mounting point;
• a clip for use with said channel in acoustically isolating wallboard panels attached to said channel from the underlying frame member includes a bracket having a first leg and a second leg, each said leg being generally parallel to each other, and wherein each said leg has an interior surface and an exterior surface, said interior surfaces being opposite each other and generally parallel to said exterior surfaces, a first portion positionable on said first leg and between a first surface of the channel and the frame member, a second portion positionable on said second leg and in contact with a second, opposite surface of the channel;
• wherein each said portion is positioned by slidingly engaging said corresponding leg;
• wherein each said portion has a first formation disposed on said exterior surface of said corresponding leg and a second formation attached to said first portion and being disposed on said interior surface of said corresponding leg;
• and
• a fastener with a head passing through said first and second portions and said mounting point;
• said first and second portions and said bracket each having at least one fastener opening in registry with corresponding openings on the other of said first and second portions, and said first and said second portions each being a resilient, acoustically dampening material such that said fastener passing through said openings and said mounting point is acoustically isolated from said bracket and from the channel.
