Fire Resistance

AAC has one of the highest hourly fire-resistance ratings per inch of any building material. AAC is non-combustible – it will not burn. AAC units offer excellent fire protection for fire-rated walls. AAC is not only versatile structurally but its fire resistance properties are outstanding.

Thermal Energy Efficiency

Autoclaved Aerated Concrete Masonry Unit (AAC) walls are energy efficient. A 6” AAC Block wall has a steady-state R-value of approximately 6 hours, and a higher total equivalent thermal mass. This means AAC can store and release thermal energy to control the temperature of indoor environments. This results in significantly reduced heating and cooling cost and efficiently working HVAC systems.

Acoustic Properties

AACs high surface mass, coupled with the mechanical vibration energy dampening within its porous structure, produces a construction material with remarkable sound insulation and absorption qualities. Since its porous internal structure is comprised of 80% air, AAC absorbs much more sound than conventional concrete and other materials, effectively reducing sound wave transmission. This makes it ideal for construction project that require a high level of acoustic insulation, such as schools, apartment, hotel and entertainment facilities.

Structural Properties

AAC products provides structural performance and its light weight may help in some engineering designs. It makes an excellent choice for high rise buildings and for low rise buildings, partition walls, infill walls, shear walls and more.

Workability

AAC products can easily cut, drilled and grooved with manual or power tools. This provides higher productivity in electrical and plumbing installations.

Sustainability

AAC products do not degrade with time, resulting in superior properties compared to other construction materials. Since AAC is alkaline in nature it does not cause any corrosion to the building materials. AAC does not have any toxic substances nor emit any odor.
