Why AAC Blocks Are Popular in Coimbatore
Coimbatore's warm climate makes thermal insulation important in construction. AAC blocks are particularly suited to this because of their cellular structure that traps air and reduces heat transfer — keeping buildings cooler in summer without increasing AC costs.
3x Lighter Than BrickReduces structural dead load. Saves on columns, beams and foundation cost.
Thermal InsulationKeeps interiors 3–5°C cooler. Reduces air conditioning costs significantly.
Faster ConstructionEach AAC block replaces 8–10 bricks. Walls go up much faster.
Fire ResistantAAC withstands high temperatures without structural failure.
Sound InsulationBetter acoustic performance than traditional brick walls.
Eco-FriendlyUses fly ash — a recycled industrial by-product. Lower carbon footprint.
AAC Blocks vs Red Bricks — Comparison
| Factor | AAC Blocks | Red Clay Bricks |
|---|
| Weight (per unit) | ~3.5 kg (6 inch) | ~3 kg (standard) |
| Size | 600 x 200 x 150 mm | 230 x 115 x 75 mm |
| Blocks per sq metre | ~8 blocks | ~60 bricks |
| Thermal insulation | Excellent | Poor |
| Construction speed | Fast (large size) | Slow (small size) |
| Dimensional accuracy | Very high | Variable |
| Dead load on structure | Low | Higher |
| Cost per sq metre | Slightly higher | Lower |
✅ For Coimbatore's hot climate, AAC blocks typically pay back the cost difference through reduced AC electricity bills within 2–3 years.
Which Size for Which Wall?
| Block Size | Use | Mortar Joint |
|---|
| 4 inch (100mm) | Internal partition walls, bathroom walls | Thin bed mortar (3mm) |
| 6 inch (150mm) | External walls, staircase walls, compound walls | Thin bed mortar (3mm) |
| 8 inch (200mm) | External walls where extra insulation needed, cold storage | Thin bed mortar (3mm) |
Important: AAC blocks use a special thin-bed AAC mortar (not regular cement mortar). Using regular mortar reduces bonding and wastes material. We supply thin-bed AAC block adhesive mortar along with block orders.
