Abstract: The present invention relates a multi-plane physical barrier that can be used to fill an orifice, hole or cavity. The barrier includes two or more relatively rigid carriers that are connected to one another by a “hinge.” The “hinge” may take a variety of forms.

Abstract: A combined baffle and reinforcing assembly is provided for use within the cavity of a structural member to dampen acoustic transmissions through the cavity and provide reinforcement in a direction transverse to the longitudinal axis of the structural member. The assembly includes a synthetic carrier which includes an interior area, marginal rim, and an attachment member preferably in the form of a clip for insertion to the corresponding hole in the wall of the structural member, and a circumscribing and continuous band of reinforcing material extending around the periphery of the carrier. The assembly may be economically manufactured by co-injection molding or insert molding of the thermally expansible material around the carrier. The marginal rim of the carrier may include base wall and a support flange for receiving the thermally expansible material thereon.
