A wall-building construction element (10) is preferably extruded from a recycled plastics material having desirable construction, insulating and fire-resistant characteristics. The elements have an upper wedge shaped section (16) and a lower complementary wedge shaped longitudinal groove (22), with a transverse wedge shaped notch (40) extending across one end of each element. A hollow core filled with insulating foam may be provided in the extruded profile, or hollow conduits for receiving electrical and plumbing utilities. |
