Clay Brick, various types, finishes and sizes for envelope use (76mm, 90mm, 110mm wall thickness)
High-performance fired clay masonry units for structural and veneer applications, manufactured to Australian Standards with excellent thermal mass, fire resistance, and durability characteristics suitable for all Australian climate zones.
High-performance fired clay masonry units for structural and veneer applications, manufactured to Australian Standards with excellent thermal mass, fire resistance, and durability characteristics suitable for all Australian climate zones.
Clay bricks are manufactured from selected clays, shales and other minerals, moulded or extruded into shape and fired in kilns at temperatures between 900-1200°C. Standard Australian dimensions are 230mm × 110mm × 76mm, with variations for 90mm and 110mm wall thicknesses. These units provide structural integrity, thermal mass benefits, and aesthetic versatility for residential and commercial construction across all Australian climate zones (BCA Zones 1-8).
