Description

Star Performer 100mm

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 from 3.6 N/mm² to 7.3 N/mm². This unique construction achieves thermal performance around 45% better than solid dense blocks, making it a versatile choice for both energy efficiency and structural reliability.

Lightweight at around 15 kg per 100 mm block, these blocks are easier to handle and quicker to lay, improving on‑site productivity. They also meet airborne sound transmission requirements, incorporate 15% recycled aggregate, and are 100% recyclable, making them a practical and sustainable option. Suitable for a wide range of applications including inner leaf walls, party walls, beam‑and‑block infill, and below DPC use in normal soil; 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.
• Acoustic Performance: Air pockets provide great sound insulation properties.
• Versatile Applications: Suitable for use as the inner leaf of cavity walls, block and beam flooring (7N only) and applications below DPC in normal soil conditions.
