Sibline Hollow Block is a non-load-bearing concrete masonry unit available in both lightweight and regular densities, designed for internal partitioning and external walls. It is produced with an automatic press in accordance with EN 771-3:2011, Category D1. The block strength can be adjusted according to the Engineer’s requirements. Several compressive strengths can be achieved for a given density. Sibline Lightweight Hollow Blocks comply with ASTM C129-11 standards at a concrete density of 1400 kg/m³.

It is manufactured using a proprietary mix design containing silica sand, Portland cement, and lightweight materials, including non-toxic flame-retardant expanded polystyrene (EPS). Sibline Lightweight Hollow Blocks are available in densities of 1200 and 1400 kg/m³, while Sibline Regular Hollow Blocks are available in a density of 2200 kg/m³.

Sibline Hollow Block is much easier to cut using a saw or hammer compared to regular cementitious blocks. It is available with rectangular-hole blocks offering better thermal insulation and enhanced fire resistance.

Hollow blocks with widths of 10, 12, 15, and 20 cm are delivered with a certain percentage of “split” blocks, which can be easily separated into two pieces on-site without the need for a hammer or saw.
