Thermalite Aircrete Coursing Brick

Thermalite coursing bricks are autoclaved aerated blocks produced in standard brick sizes for use in bonding and infill to ensure that a uniform thermal performance is achieved throughout the wall. Hi-Strength Coursing Bricks and Blocks are also available for use in walls built of Hi-Strength 7 or 10 blocks. The Thermalite Hi-Strength Coursing Blocks retain the standard 440mm block length so reduce the number of mortar joints required when detailing, saving time and money.
