At-a-glance signals

Standard Australian clay brick (230x110x76mm) with rough finish texture. Non-combustible masonry unit suitable for structural walls, providing excellent fire resistance and durability.

Overview
Executive summary

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.

Best when…
  • Non-combustible with FRL up to 240 minutes
  • 100+ year service life expectancy
  • Suitable for all BAL ratings including BAL-FZ
  • High compressive strength (25-34 MPa typical)
  • Excellent thermal mass (149.6 kJ/m²·K)
  • Minimal maintenance requirements
  • Pest and termite resistant
  • 100% recyclable at end of life
  • Good acoustic performance (STC 45-48 dB)
  • Locally manufactured in Australia
