At-a-glance signals

High-density compressed fibre cement sheets providing non-combustible, moisture-resistant substrate for flooring, cladding, and wet area applications in Australian construction

Overview
Executive summary

Compressed fibre cement (CFC) sheets are manufactured from Portland cement, ground sand, cellulose fibres, and water under high pressure. These sheets offer superior strength, durability, and fire resistance compared to standard fibre cement. Available in smooth finish with square edges, they are suitable for internal and external applications including structural flooring, wall cladding, wet areas, and bushfire-prone construction up to BAL-FZ rating.
