FP®-900/FirePro® is a high quality laminated calcium silicate board. It does not contain asbestos, sepiolite or other inorganic fibres and is free from formaldehyde. It is a strong and lightweight, non-combustible building board for use in many fire resisting applications up to 240 minutes fire rating performance to international standards including BS, EN, GB, and ISO. FP®-900/ FirePro® is made of special fire resistant minerals materials and has undergone a sophisticated process. It is simple to work with and fix, easy to decorate, resistant to the effects of moisture and will not rot and decay. FP®-900/FirePro® 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.





FP®-900/FirePro® is off-white in color and has a smooth sanded surface on one side and a slightly textured reverse. It consists of fire rated minerals and calcium silicate matrix reinforced with selected fibres and special fillers. The board is then cured under an autoclave process where high pressure and steam is induced to ensure its intrinsic fire resistant property.

Apart from fire rating properties, FP®-900/FirePro® is also an ideal building board for use in constructions where there is a need for resistance to damp or high humidity. It contains no water soluble additives and will not rot, degrade or deteriorate. FP®-900/FirePro® will absorb water causing some loss of strength, which is fully recovered on drying. Any staining on the board caused by leakage can be easily painted over. Moisture will not cause leaching or efflorescence and has no permanent effect on the board. FP®-900/FirePro® is classified as non-combustible when tested in accordance with BS 476: Part 4, BS EN ISO 1182 and GB8624: Grade A. Many fire resistant constructions such as wall, ceiling, duct, protected shaft or cavity barrier had used FP®-900/FirePro® as the core element. As revealed from the tests, FP®-900/FirePro® is capable of resisting fire attack up to 1200°C for 240 minutes. Please consult Soben International for fire engineering design and details of local equivalence.

Health & Safety 


FP®-900/FirePro® is formulated without asbestos, sepiolite or any inorganic fibres. When using power saws or sanders in a confined space, dust extraction equipment is recommended to control dust levels. FP®-900/FirePro® is designed for non-load bearing construction. Horizontal boards or ceiling panels must not be walked on as they are not designed to take additional loads between supports; if there is a risk of this occurring, warning notices should be displayed. Fixers must ensure that they work from adequate and safe platforms where necessary.

Note: All physical performance values of products depicted in this catalogue are averages based on the standard production. The figures may be changed dependent on the test method used.
