AAC blocks suppliers in Mumbai
AAC blocks suppliers in Mumbai like Builders First Source help builders shift from heavy, inefficient materials to lightweight, high‑performance walling that speeds up construction and improves building comfort. AAC (Autoclaved Aerated Concrete) blocks combine strength, insulation, and sustainability, making them a preferred choice for modern residential, commercial, and infrastructure projects.
AAC blocks overview
AAC blocks are factory‑made, lightweight concrete masonry units produced from a mix of cement, lime, sand or fly ash, water, and a small dose of aluminium powder that creates millions of microscopic air pores inside the block. These pores give AAC its low density, excellent thermal and acoustic properties, and ease of handling on site while still achieving required compressive strength after autoclave curing at high pressure and temperature.
Key features and benefits
Lightweight yet strong: AAC blocks can weigh 30–80% less than conventional clay bricks or solid concrete blocks while still meeting structural requirements, reducing dead load and steel consumption in multi‑storey buildings.
Faster construction: Larger block sizes and easier handling can speed up masonry work by up to 30%, with lower mortar and plaster usage due to precise dimensions and smoother surfaces.
Thermal and sound insulation: The air‑entrained structure delivers excellent heat and noise insulation, improving indoor comfort and lowering HVAC energy costs over the life of the building.
Fire and pest resistance: AAC is inorganic, non‑combustible, and fire‑resistant for several hours, and does not support termite or fungal growth, making it safer and more durable than many traditional materials.
Eco‑friendly choice: Use of fly ash, reduced raw material consumption, and lower energy required for transport make AAC a greener alternative with reduced overall CO₂ footprint compared to solid clay bricks.
Types and applications
AAC blocks are available in different densities and grades for specific uses, ranging from low‑density non‑loadbearing units for partitions to higher‑density blocks for loadbearing external walls and high‑rise applications. Specialized variants such as enhanced thermal, fire‑resistant, or sound‑insulating blocks are used in hospitals, hotels, schools, industrial sheds, and other buildings where comfort and safety standards are higher.
Why source AAC blocks from a specialist supplier in Mumbai
A dedicated AAC blocks supplier with a strong distribution network ensures consistent stock, grade‑wise options, and timely deliveries to sites across Mumbai and surrounding regions, which is crucial for uninterrupted project execution. In addition, technical support on block selection, jointing mortars, curing, and compatible finishes helps builders extract full performance benefits and optimize structural design, material consumption, and overall project cost.
