COMPARISON BETWEEN AAC BLOCKS AND RED CLAY BRICKS

Maximum of 2-3 hrs

0.81 w/m k

Pollutes the air and increased use of top soil

Uneven; hence no proper contact and requires very thick layer of plaster usually 20-25 mm (minimum)

50db for 250mm thick wall

10-20% 

Many joints and very thick mortar (20-40) consumption

Pollution free and no usage of top soil

Precisely made for a perfect contact from all sides; hence optimal plaster of 6-8mm only

45db for 200mm thick wall

Less than 5%

Fewer joints = low consumption of mortar
