Abstract
Siding panels and intermediate articles of their manufacture are provided. The siding panels include a central portion including an aesthetic pattern and a pair of lateral edge portions which are formed while the polymeric material is still above its heat deflection temperature, and preferably, when the central portion has been hot-formed and cooled. This invention improves the art for vacuum-forming siding panels, dentil molding and other building products made by continuous vacuum forming.
