Aerated block vs brick: which is better
The main question of house building: warm lightweight aerated concrete versus strong durable brick.
Aerated block100 €/m³
Brick200 €/m³
Diferencias clave
- Aerated block is roughly 50% cheaper (100 €/m³ vs 200 €/m³).
- Aerated block is warmer: lower thermal conductivity (0.12 vs 0.56 W/(m·K)).
- Brick handles moisture better: 10% water absorption vs 20%.
- Brick is stronger in compression (15 MPa vs 2.5 MPa).
