Fireproof board
FireDef
FireDef is a high quality laminated calcium silicate board. It is made of fire rated minerals and calcium silicate matrix reinforced with selected fibres and special fillers and has undergone a sophisticated process, which offers superior fire resistance. FireDef is cured under an autoclave
process where high pressure and steam is induced to ensure its intrinsic fire resistant property, The board is strong lightweight, and non-combustible.

【Introduction of FireDef】
FireDef is a high quality laminated calcium silicate board. It is made of fire rated minerals and calcium silicate matrix reinforced with selected fibres and special fillers and has undergone a sophisticated process, which offers superior fire resistance. FireDef is cured under an autoclave
process where high pressure and steam is induced to ensure its intrinsic fire resistant property, The board is strong lightweight, and non-combustible. Many fire resistant constructions such as wall.
ceiling, duct, protected shaft or cavity barrier had used Firedef as the core element.
Apart from fire rating properties. FireDef, contains no water soluble additives, is resistant to the effects of moisture and can be used in damp or humid conditions. It is off-white in color and has a smooth finish on one face with a sanded reverse face, which can be left undecorated or easily
finished with paints, tiles or wallpapers. It is simple to work with and fix, easy to decorate, resistant to the effects of moisture and will not decay.
FireDef is manufactured to ISO 9001 quality management system and ISO14001 environmental management system.
Firedef is environmental friendly. It does not contain asbestos, sepiolite or other inorganic fibres and is free from toxic emissions and formaldehyde. Firedef can be produced with bevelled edges for butt jointing purposes.
