Autoclaved aerated concrete (AAC) has failed to gain a foothold in the North American construction market despite its popularity in Europe. In North America the most common wall construction technology with a stucco finish, except in certain niche markets, is the exterior insulation finish system (EIFS). Because of the limitations of EIFS, a wall assembly technology has been developed that marries frame construction of all types with 75 mm thick AAC blocks and medium‐density sprayfoam polyurethane insulation. This composite technology allows more rapid assembly and higher performance than conventional AAC block construction. The completed stucco‐finished wall has much higher thermal resistance, load and shear strength, water and vapor resistance, and acoustical performance than single‐wythe AAC block construction. In North America, where AAC is used very little, this technology will allow much broader acceptance as even more benefits will be realized over prevailing technologies. This technology, known as System5zero, has two patents in the United States and is approaching commercialization. This paper and presentation will discuss development, testing, benefits, and applications of System5zero.
