Cellular Dense Concrete Blocks are manufactured to BS EN 771-3 using high quality class 2 aggregates. These group 2 units are blinded on one bed face to allow for a full bed of mortar and their lower weight means easier manual handling.
In common with solid dense blocks, Cellular dense consist of up to 30% recycled raw materials and their enhanced thermal properties make them an excellent solution for higher strength, sustainable building.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Thomas Armstrong Group is consulted before specifying.
