Autoclaved Aerated Concrete (AAC) is a precast, manufactured building stone made of all-natural raw materials. It is an economical, environmentally friendly, cellular, lightweight, structural material that provides thermal and acoustic insulation as well as fire and termite resistance. AAC is available in a variety of forms, ranging from wall and roof panels to blocks and lintels. A material like wood but without the disadvantages of combustibility, decay, and termite damage. Steel bars or mesh can also be placed into the mold for reinforcing. Depending on the density, AAC has a compressive strength of 300 to 900 pounds per square inch, which makes it a structural material for low-rise buildings. With an R-value of 1.25 per inch, AAC significantly outperforms conventional concrete block or poured concrete (having about R-0.1 per inch). Study showed that an 8' AAC wall performs much better than a conventional wood stud wall system with R-30 insulation. AAC 4-inch wall panels have a fire rating of 4 hours (ASTM E-119) and acoustically perform with an STC rating of 41. Because of the thermal mass of the AAC and its ability to store and release energy over time, AAC is most beneficial in climates where outdoor temperature fluctuates over a 24-hour period from above to below the indoor temperature setpoint.
