Description

Common clay bricks are traditional fired clay masonry units manufactured to AS/NZS 4455.1:2008 standards. With dimensions of 230x110x76mm, these bricks are fired at temperatures exceeding 1000°C, creating a durable, non-combustible building material. The rough finish provides enhanced mortar adhesion and is typically used for rendered or painted walls rather than face brick applications.

Typical Uses
  • Load-bearing walls (up to 4 storeys)
  • External veneer cladding
  • Internal partition walls
  • Retaining walls
  • Fire-rated wall construction
  • Acoustic barriers
  • Garden walls and landscaping
  • Rendered wall substrates
  • Bushfire-prone area construction (BAL-12.5 to BAL-FZ)

Clay bricks have been used in Australian construction since European settlement in 1788. The establishment of local brickworks followed settlement patterns, with major manufacturers like Austral Bricks (1908) and PGH (1893) becoming industry leaders. Australian clay brick manufacturing evolved from hand-moulding to mechanised extrusion in the early 20th century. Modern kilns achieve consistent quality through computer-controlled firing cycles. The development of AS/NZS 4455 standards in 1997 (updated 2008) standardised dimensions and quality requirements. Recent innovations include improved thermal performance through coring patterns and the development of carbon-neutral manufacturing processes by leading manufacturers.
