LOW DENSITY LIGHTWEIGHT AGGREGATE BLOCKS

These lightweight aggregate blocks are designed to offer the builder a low weight, load-bearing block with enhanced thermal properties suitable for a wide range of applications.

Ultralite blocks are manufactured to BS EN 771-3 and are ISO 9001 Quality Assured, ISO 14001 Environmentally Certified and hold BES 6001 ‘Excellent’.

Weighing less than 20kg, these high-quality aggregate blocks are manufactured from low density, quality aggregates and available in a range of sizes. These lightweight concrete blocks are only available in a ‘Standard’ texture finish providing an excellent surface for mortars, renders and plasters.
