Fiber Cement Board: Types, Sizes, and Applications
1. Classification by Material
Fiber cement boards can be categorized based on their composition and manufacturing process:
- By Fiber Type
- Asbestos fiber cement boards
- Synthetic fiber cement boards (e.g., cellulose, PVA fiber)
- Hybrid fiber cement boards (asbestos + synthetic fibers)
- By Cement Type
- Ordinary Portland cement boards
- Low-alkali cement boards (anti-efflorescence, ideal for interiors)
- By Production Process
Common Product Types
| Name (Abbreviation) | Key Features |
|---|
| Fiber-Reinforced Low-Alkali Board (TK Board) | Moisture-resistant, crack-resistant, suitable for partitions & ceilings |
| Asbestos-Free Large-Format Pressurized Board (NAFC Board) | High strength, large panels, ideal for exteriors & structural use |
| Asbestos-Free Lightweight Board (NAL Board) | Lightweight, easy to install, used for interior walls |
| Non-Combustible Fiber Cement Board | A1 fire-rated, used in fireproof zones |
| Asbestos Cement Pressure Board | Traditional material, being phased out |
| Glass Fiber Reinforced Cement (GRC) | High flexibility, decorative applications |
2. Standard Sizes
Fiber-Reinforced Low-Alkali Board (TK Board)
| Type | Length (mm) | Width (mm) | Thickness (mm) |
|---|
| Class I | 1220, 1820, 2420 | 820, 920 | 5, 6 |
| Class II | 1220, 1800, 2400 | 820, 900, 920 | 5, 6 |
Asbestos-Free Lightweight Board (NAL Board)
| Length (mm) | Width (mm) | Thickness (mm) |
|---|
| 1800, 2400 | 900, 1200 | 4, 5, 6, 8 |
Asbestos-Free Large-Format Pressurized Board (NAFC Board)
| Length (mm) | Width (mm) | Thickness (mm) |
|---|
| 2400, 3000 | 1200 | 4–25 (customizable) |
Other Key Sizes
- Non-Combustible Board: 2440×1220mm, thickness 4–20mm (Eterboard up to 20mm)
- GRC Board: Max 2700×1200mm, thickness 10–20mm (ideal for decorative designs)
3. Recommended Applications
- Exterior/Structural Use: NAFC pressurized boards (thickness ≥8mm)
- Interior Walls: TK or NAL boards (lightweight, easy to cut)
- Fireproofing: Non-combustible boards (A1 fire rating)
- Decorative Purposes: GRC boards (high flexibility for custom designs)
