Abstract
Building or construction related components such as floor tiles, ceiling tiles, trim moldings, corner guards, sound proofing or insulating panels, dock bumpers and the like are formed by blow molding a hollow parison to the desired exterior shape, such that the parison becomes the exterior surface of the desired article, and thereafter blowing a plastic foam composition into the interior of the parison. Integrally formed male and female connectors for sliding, or snap-fit engagement are provided to attach moldings and other components in end-to-end relationship with each other, or to wall surfaces and the like. In an alternative embodiment, coextrusion is employed to form the various construction related components.
