Overview
Executive summary

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.

Best when…
  • Excellent fire resistance (90-240 minutes for 110mm wall)
  • High thermal mass for temperature regulation
  • 100+ year service life with minimal maintenance
  • Locally manufactured reducing transport emissions
  • Non-combustible material suitable for BAL-FZ zones
  • Good acoustic insulation (Rw 45-50)
  • Termite and pest resistant
  • Recyclable at end of life
  • UV stable with no colour fading
  • Moisture resistant with proper detailing
