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.
