Calcium Silicate Board
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, noncombustible 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.
