Star Performer 100mm Cellular Concrete Block 3.6N

Star Performer 100mm – Cellular Concrete Block

The Star Performer Cellular Concrete Block is a cellular dense aggregate block designed with three internal cavities to deliver excellent thermal efficiency and strength. Unlike traditional solid dense blocks, the three‑cavity design reduces weight without compromising load‑bearing capability, offering compressive strengths of 3.6 N/mm². This concrete block achieves a thermal performance around 45% better than solid dense blocks, making it a ideal choice for both energy efficiency and structural reliability.

These blocks are easier to handle and quicker to lay, improving on site productivity. Suitable for a wide range of applications including inner leaf walls, party walls, and below DPC, the Star Performer Cellular Block provides a one block solution for modern construction needs.

Key Features & Benefits:

• Thermal Efficiency: 45% better than a solid dense block.
