Abstract
A door panel section and a method of making a door panel section having a polyvinylchloride front skin, a non-metallic rear skin and a polyurethane rigid core. The polyurethane rigid core unitizes the two skins to make the panel section with a rigid lightweight structure. The polyurethane mechanically and chemically bonds to the skins made of polyvinylchloride to create a strong connection thereto. Hardware mounting members are attached to the rear skin permitting adjacent panel sections to be pivotally connected to each other.
