  1. 1. An interior dome covering for automotive vehicles that is insulating and self-supporting, which comprises a molded laminate structure having a contoured configuration with a variable cross-section, and consisting of at least two sheets of crosslinked polyethylene foam permanently bonded together with an intermediate polymer-containing non-foamed reinforcing layer to form a multiple-layered structure; said reinforcing layer being made from a material selected from the group consisting of polyethylene, polypropylene, ethylene-propylene copolymers, vulcanized fiber reinforced rubber, polyvinylchloride, and cellulosic material impregnated with phenolic resin or melamine resin.
  2. 3. An insulating interior dome covering fashioned to be self-supporting, for automotive vehicles which comprises a molded laminate structure having a contoured configuration with a variable cross-section, and consisting of at least two crosslinked polyethylene foam sheets permanently bonded to intermediate polymer-containing non-foamed reinforcing layers to form a multiple-layer structure and profiled reinforcing insert members made of thermoplastic resin and shaped and arranged to span the laminate structure in at least one of the longitudinal direction and the transverse direction of said moled laminate structure; said reinforcing layer being made from a material selected from the group consisting of polyethylene, polypropylene, ethylene-propylene copolymers, vulcanized fiber reinforced rubber, polyvinylchloride, and cellulosic material impregnated with phenolic resin or melamine resin.
  3. 16.16.
