Fiber Cement Board
Fiber cement board is a non-asbestos fiber cement product composed of Portland cement, cellulose fiber, and silica sand. Manufactured using an advanced autoclave process, it combines the strength and durability of cement with the workability of wood and excellent dimensional stability.
This non-combustible, multi-purpose flat board is available in various thicknesses and is suitable for ceiling, wall, and floor applications, both for interior and exterior use. The board can be precisely calibrated and further laminated or coated with materials such as paint, wood veneer, or aluminum plates, offering excellent design flexibility.
