The owner of this mansion shipped in the autoclaved aerated concrete material from Europe. Over 360 families lost their homes to this 1993 fire. Subsequent investigation concluded that nearly all of those structures burned from the inside out. Meaning the wall material of the homes transferred heat and the interior materials combusted (wall paper, insulation, drywall, 2x4 furring strips, etc.) AAC is non-combustible and restrains heat transfer, saving property and lives.

Autoclaved aerated concrete provides the highest security against fire. It is a non-combustible material and highly heat resistant. This means materials on the opposite side of an AAC wall from a fire will not burn..

For example, concrete masonry units (CMUs) commonly used for fire walls have a much higher transfer rate. Also, CMU walls are typically finished with wood furring strips, insulation, and drywall – all of which can be combustible at temperatures transferred through CMU.

Besides being fire- and heat-resistant, AAC does not give off any smoke or toxic gases, which can endanger human life more than fire itself. Other products such as Insulated Concrete Forms (ICFs) utilize a rigid foam to insulate and initially form the wall system. This material, as with any 'foam' -type product, melts quickly under low heat and produces highly toxic gases.

For fire protection in commercial and residential structures - especially schools, hotels, multi-family residences, and assisted living facilities, AAC is the right choice in construction material.
