A composite building block with a connective structure between the inner and outer wall units is presented. The wall units can be made of cement, clay brick, or similar materials. The connective structure is made of a material different than the wall units and may be integrally formed per the requirements of a particular wall construction project. In one embodiment, the connective structure comprises a center form, and one or more arms have connectors that connect to corresponding connectors integrally formed on the wall units. The center form may partition the cavity between the inner and outer wall units into two or more cavities, which may then be partially filled with, for example, insulative material or load-bearing materials, such as concrete.

The block unit of claim 1, wherein at least one connector is an insert-type connector and one of the first and second walls has a connector formation that is matingly engaged by the connector.3. The block unit of claim 2, wherein the connector formation is a receptacle and the insert-type connector is inserted into the receptacle, such that the insert-type connector is frictionally engaged by the receptacle.4. The block unit of claim 1, wherein each of the connectors is matingly engaged in one of the first and second walls.5. The block unit of claim 1, wherein the connective structure is substantially composed of a plastic material.6. The block unit of claim 1, wherein the center form comprises a partition that forms a first cavity with the first wall and a second cavity with the second wall.7. The block unit of claim 6, wherein the first cavity is larger than the second cavity.8. The block unit of claim 1, wherein at least one connector has sides extending outwardly and is received in a dovetail-shaped connector formation in the first or second wall.9. A discrete, preassembled, composite block unit for independent placement as a unit with other laterally and vertically adjacent units to form a mortared wall structure, comprising:a first wall and a second wall, at least one of which is load bearing for vertical loads and made from a first, masonry-type material, each said wall having at least one mortar receiving surface for forming a mortar joint with said adjacent block units; and a connective structure formed of a second, non-masonry-type material and connected between the first and second walls, said connective structure having at least two connectors; wherein each of the connectors is connected to one of the first and second walls, such that prior to placement of the block unit in a wall structure the first and second walls are securely positioned with respect to one another as opposite faces of a discrete, substantially rectangular block, each face having a face area; wherein the connective structure is free of direct, structural connection to any wall of each adjacent block unit when the block unit is in a wall structure; wherein the connective structure comprises arms supporting the at least two connectors and said arms provide a thermal conduction path of limited vertical cross-sectional area relative to either wall face area; and wherein the first wall and second wall each have an upper edge when connected by the connective structure and the arms of the connective structure comprise: two end arms and a center arm; wherein the center arm is vertically displaced with respect to the end arms to a position nearer the said upper edges of the first wall and second wall. 10. The block unit of claim 9, wherein the center arm comprises at least one recess for accommodating a horizontal reinforcing bar.11.
