Advantages of AAC

  • large variety of sizes: AAC can be produced in a large variety of sizes, from standard blocks to large reinforced panels;

  • excellent thermal insulation: AAC has a very low thermal conductivity and therefore a very high thermal energy efficiency is achieved. This results in savings on heating and cooling costs;

  • extreme lightweight: AAC weighs approximately 50% less than other comparable building products; 

  • high compressive strength: AAC is a solid product, therefore making it highly load bearing. The entire surface area is used in structural calculations;

  • high dimensional accuracy: As a result of its dimensional accuracy, AAC is extremely easy to install, as no thick set mortar is required;

  • great acoustic insulation: The porous structure of AAC provides a high acoustic insulation; 

  • high fire resistance: AAC has an extremely high fire rating of at least 4 hours and more;

  • termite resistance: AAC can not be damaged by termites or insects;

  • high workability: As a result of the excellent size/weight ratio, constructing with AAC is very rapid. Even though AAC is a solid building material, it can be cut, sawn, drilled, nailed and milled like wood, making it an extremely workable product.
