fiber cement board for exterior

Introduction DSfiber 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,DS board is light weight, strong, moisture resistant, will not warp, swell or decay in wet area. The board is manufactured to ISO 9001 quality management system and ISO14001 environmental management system, and has obtained the Green Product Label Award issued by National Environment Protection Bureau.

When using power saws or sanders in a confined space, dust extraction equipment is recommended to control dust levels. Fixers must ensure that they work from adequate and safe platforms where necessary.Note: All physical performance values of productsof the figures may be changed dependent on the test method used.
