Description

Standard Australian clay brick manufactured from locally sourced clay and shale, kiln-fired at temperatures between 900-1200°C. Features natural clay finish with typical red-orange coloration, though colour varies by clay composition and firing temperature. Designed for single or double brick construction, cavity walls, and veneer applications. Provides inherent fire resistance, thermal mass, and acoustic insulation properties suitable for all Australian climate zones.

Typical Uses
  • External load-bearing walls
  • Internal partition walls
  • Cavity wall construction
  • Brick veneer cladding
  • Fire-rated wall assemblies
  • Acoustic barriers
  • Retaining walls
  • Facade applications
  • Heritage restoration
  • Bushfire-resistant construction (BAL-FZ rated)

Clay bricks have been used in Australian construction since European settlement in 1788. Early convict-made bricks established the material's importance in Australian architecture. The introduction of mechanised production in the 1850s and continuous kilns in the early 1900s revolutionised the industry. Modern Australian brick manufacturing follows world-leading standards with approximately 50 production facilities nationwide, producing over 1.5 billion bricks annually. The material remains fundamental to Australian residential construction with over 50% of new homes featuring brick.
