SHERA Board
SHERA Board is a non-asbestos fibre-cement building board composed of Portland cement, cellulose fibre and refined sand. Using a manufacturing process called autoclave, SHERA board acquires the strength, durability of cement plus easy workability and dimensional stability. SHERA Boards come in various formats and can be used in a wide variety of building applications.
Benefits
SHERA Boards are:
- Weather resistant
- Immune to water damage
- Fire resistant
- Provides sound insulation
- Shatter resistant
- Low shrinkage
- Flexible
- High degree of workability
- Termite resistant
Various Categories of Building Boards
SHERA Boards come in square cut edge, recessed edge, and decorative surface.
