High-Strength 4x8ft Cement Fiber Sheeting For Exterior Cladding And Partition Walls
Product Introduction Of Fiber Cement Board:
Fiber-Reinforced Cement Board Flat External Wall Partition Wall Cement Board 1220*2440mm revolutionizes exterior cladding and interior partitioning with advanced material science. This engineered composite combines Type III high-density Portland cement with cross-layered cellulose fibers and mineralized quartz particles, creating a dimensionally stable panel specifically designed for load-bearing applications. The board's unique manufacturing process involves high-pressure steam curing at 180°C, achieving 94% hydration completeness for maximum structural performance.
Key Features Of Fiber Cement Board:
- Advanced Bonding Technology: Quartz-reinforced edges withstand 25kN/m racking force (EN 594).
- Thermal Break Design: Integrated air pockets reduce thermal bridging by 38% compared to solid panels.
- Surface Hardness: 5H pencil hardness rating resists scratching in high-traffic areas.
- UV Stability: Maintains colorfastness after 3,000 hours QUV testing (ASTM G154).
