MultiPro. is a calcium silicate 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 use in a wide range of internal and semi-exposed external applications in building construction projects. It is an economical building board material with fire-proofing property to replace concrete or block wall for the construction of non-load bearing elements. Unlike most plywood, cement-bonded particle board, gypsum boards or magnesium boards, MultiPro. is light weight, strong and moisture resistant which 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 China National Environment Protection Bureau.

MultiPro. is a calcium silicate board, off-white in color, and has a smooth finish on one side and a slightly textured reverse. It consists of calcium silicate matrix, fire rated mineral, reinforced with selected fibres and special fillers. The board is cured under an autoclave process where high pressure and high steam is induced to ensure a complete chemical reaction, thus providing the board with excellent dimensional stability and chemical resistance.

MultiPro. contains no water soluble additives and will not rot, degrade or deteriorate. The board will absorb water causing some loss of strength, which is fully recovered on drying. Any staining on the panels caused by leakage can be easily painted over. Moisture will not cause leaching or efflorescence and has no permanent effect on the board.
MultiPro. is non-combustible when tested in accordance with BS 476: Part 4, 5, 6 & 7, BS EN ISO 1182 and GB8624. The board provides a degree of thermal insulation and is resistance to continuous operating temperature up to 1000C. MultiPro. dry wall system complies with the requirements of BS 476: Part 22, 1987 and BS EN 1364-1: 1999 for 1 hour fire rating partition in integrity and insulation and GB/T 9978 1999 for 2 hour fire rating partition with integrity and insulation.
