摘要

The bottom part is provided with thermal insulation of insulating material adjacent to its inner side, where the part is designed as a one-piece multi-layer body having a fiber-reinforced polyester layer (4). Another layer (5) of the insulating material is formed from polyurethane foam or fiber. The polyester is reinforced with glass fibers, where the insulating foam has fiberglass. An independent claim is also included for a method for manufacturing a bottom part.
