The cited B.F. Goodrich Company reference EP AO 320745 has no relevance to the amended claims which call for the components to be a coextrusion of a hollow substrate and a smooth protective skin covering the substrate on surfaces which are exposed as exterior walls when the component is interlocked with mating components while the transverse walls which are interior walls when the component is interlocked with mating components have openings cut therefrom spaced along the length thereof. When applicant's component is assembled into a building structure, only the smooth protective skin is presented to the exterior to provide the requisite aesthetics and protection of the underlying substrate. The substrate on the other hand which is interior of the externally exposed surfaces when the component is interlocked with other components can include any suitable reinforcing and expansion controlling agents and can include reground or reprocessed material. Therefore the material cut from previously formed components is material suitable as substrate material without adversely affecting the aesthetics or weathering of the component due to the protective skin which covers off any and all imperfections and irregularities in the underlying substrate surface.
Thus by the provision of the holes, the amount of material required to manufacture the component is significantly reduced as is the weight of the component and this material is not wasted because it can be used as a source of substrate material for subsequently manufactured components. Further the provision of the openings in the interior walls of the structure formed by the interlocking components provides internal communication therebetween and allows, for example, the free flow of concrete between interlocked components forming the walls of the building to give permanency to the walls as well as permanency to the interlock between the
components.
The substantial cost savings achieved by the invention becomes a most important factor in reducing the costs of housing or other building structures.
The Goldbach FR A-2007695 reference is totally unrelated to an extruded product and has no pertinency to the above discussed features of applicant's invention.
