Abstract
Abstract Wall units for buildings are prepared by positioning pieces of insulation (30-33) in a mold (20) with furring members (42) between the blocks of insulation (30-33). Reinforcement members (46) can also be positioned in the mold (20), and preferably are secured to the furring members (42). A cementitious material is poured in the mold (20) and cured to form a light weight wall unit having good strength and insulating characteristics. Several wall units are cast in suitable shapes to form, when assembled, the walls of a building. Suitable fastening structure (64, 65) can be incorporated into the wall units to facilitate the interconnection of adjacent units. Additional fastening strcture (60, 61) can be provided in the wall units by which the wall units can be secured to a foundation.
