Siporex AAC Blocks
Siporex AAC Blocks are lightweight Autoclaved Aerated Concrete (AAC) blocks used for residential, commercial, institutional and industrial construction. Siporex is one of the established AAC brands in India and is currently owned and supplied in India by Biltech Building Elements Limited.
The cellular structure of AAC gives Siporex blocks a lower density than conventional masonry materials while providing useful thermal insulation, fire resistance and ease of handling during construction.
Standards & Quality
Siporex AAC Blocks are manufactured with reference to IS 2185 (Part 3):1984, the Indian Standard for autoclaved cellular aerated concrete blocks.
Biltech states that its Siporex and Biltech ACE AAC Blocks are certified under green-building product programmes including CII GreenPro and GRIHA.
Common Siporex AAC Block Sizes
Siporex AAC Blocks are available in multiple thicknesses. Common sizes include:
- 100 mm / 4 inch
- 125 mm / 5 inch
- 150 mm / 6 inch
- 200 mm / 8 inch
- 225 mm / 9 inch
Block length, height and thickness combinations may vary depending on the manufacturing plant, current stock and project requirement. Confirm the required dimensions with Parts2Build before ordering.
Key Benefits of Siporex AAC Blocks
- Lightweight: Lower density reduces the dead load contributed by masonry walls compared with conventional masonry materials.
- Thermal insulation: The cellular structure of AAC provides good resistance to heat transfer and can contribute to improved indoor thermal comfort.
- Fire resistance: AAC is an inorganic and non-combustible masonry material. Fire performance varies according to wall thickness and construction.
- Dimensional consistency: Factory manufacturing provides relatively uniform block dimensions for accurate masonry construction.
- Workability: Siporex AAC Blocks can be cut, drilled and shaped using suitable tools for electrical, plumbing and other building-service requirements.
- Acoustic performance: AAC wall systems can provide useful sound-reduction characteristics depending on block thickness and wall construction.
- Faster masonry work: The larger dimensions and lower weight of AAC blocks can help improve handling and masonry productivity compared with conventional bricks.
