For external walls in Chennai, 6 inch (150mm) AAC block is the most commonly used size — it provides excellent thermal insulation for Tamil Nadu heat while meeting standard structural wall requirements. For internal partitions, 4 inch (100mm) is the standard choice.

Per m² of wall, AAC blocks cost similar to red bricks in material cost. However, AAC offers significant savings in: labour (3–4× faster to lay), plastering (thinner coat needed due to flat surface), reduced cement mortar consumption, and lower structural steel due to reduced dead load. Overall project cost with AAC is typically 8–12% lower than red brick construction.

One standard AAC block (600×200mm face) covers 0.12 m² of wall area. Therefore 1 m² of wall requires approximately 8.3 blocks. For 100 sq m of wall (both sides of a 50 sq m room), you need approximately 833 blocks. Always add 5% wastage for cutting.
