Abstract:
1. A composite construction system comprising: a load bearing non-sheathed frame an AAC concrete construction unit, and an internal cavity of at least 1″ width between the load-bearing frame and the AAC construction unit, wherein one side of the AAC concrete construction unit faces towards the load bearing non-sheathed frame, further wherein the load bearing non-sheathed frame is adhered to the AAC concrete construction unit using at least a single layer of urethane foam interposed between the load bearing non-sheathed frame and the AAC concrete completely filling the internal cavity, wherein the layer of urethane foam prevents thermal bridging between the load bearing non-sheathed frame and the AAC concrete; and a plurality of thermally non-conductive connection devices between the load bearing non-sheathed frame and the AAC concrete construction unit.
