摘要： A cavity filler insert for use in a cavity of a structural member is disclosed. According to one embodiment of the invention, the cavity filler insert is substantially planar in shape and includes a carrier, a thermally expandable material operably coupled with and supported by at least a portion of the carrier and extending at least around substantially the entire periphery of said cavity filler insert, and an attachment member for securing the cavity filler insert to the structural member. Once activated by heating so as to cause the expandable material to foam, the cavity filler insert effectively reduces both air-borne and structure-borne noise by dampening sound and vibration within hollow portions of vehicles and the like.
