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
