Fiber cement board
Introduction
High Density and Strength fiber cement board is a high quality calcium silicate architectural board reinforced with selected cellulose fibres and fillers. It is 100% free from asbestos, sepiolite, inorganic fibres or formaldehyde. The board is versatile and suitable for general use of internal and direct weathering applications when used in conjunction with external grade texture finish or other surface coating in new construction or refurbishment projects. It is an economical, non-combustible building board material to replace traditional concrete / clay block or cement-bonded particle board for the construction of non-load bearing elements. Unlike most plywood, cement-bonded particle boards, gypsum boards or magnesium boards, fiber cemnet board is light weight, strong, moisture resistant, will not warp, swell or decay in wet area.
