A large-size paneling part made of thermoplastic synthetic resins for automotive vehicle interiors or equivalent uses includes a support made of polyolefin particle foam onto which is laminated a decorative layer of polymeric material having a predominantly polyolefin structure during forming of the molded part. This decorative layer includes a multilayer knit mesh or woven fabric with incorporated spacers of preferably polyolefinic polymer threads, having a decorative textile surface. This layer may be laminated on the topside with a decoratively designed film, predominantly on the basis of olefinic polymers or, respectively, be laminated additionally on the rear side with a polyolefin film.
