What Is Fiber Cement Board Siding? The Complete Guide

Fiber cement board siding has revolutionized modern construction since its development in the 1970s as a safer alternative to asbestos-containing materials. This durable building solution combines cement with reinforcing fibers to create versatile panels for diverse architectural applications.

What Is Fiber Cement Board Siding Made Of?

Fiber cement board siding consists of:

• Cement base material
• Mineral or cellulose fibers
• Binding agents
• Additives for enhanced performance

The manufacturing process involves pulping, forming, pressing, and curing to create strong, dimensionally stable panels.

Standard Sizes of Fiber Cement Board Siding

Fiber cement board siding typically comes in:

• Length: 2000mm-2440mm (78″-96″)
• Width: 1000mm-1220mm (39″-48″)
• Thickness: 4-12mm (0.16″-0.47″) standard

Key Classifications of Fiber Cement Board Siding

1. By Fiber Content

• Non-asbestos (modern standard)
• Asbestos-containing (historical, now obsolete)

2. By Density

• Low density (0.9-1.2g/cm³) – ceilings/interior walls
• Medium density (1.2-1.5g/cm³) – partitions
• High density (1.5-2.0g/cm³) – exterior siding

3. By Pressure Treatment

• Regular boards
• Pressure-treated boards (higher density)
