Abstract
The invention relates to a filler body (1) for acoustic and thermal sealing of hollow spaces in vehicle bodywork, constituted as a molded part of resilient, porous material (4) of sufficient restoring resilience, enveloped in foil, which part is subjected to a vacuum prior to introduction into the hollow space (5). The molded part is self-supporting and has, in the direction of introduction, which is perpendicular to the plane of installation, a large bending stiffness by virtue of a flat, thin intermediate layer (3).
