Kalsiboard
BUILDING MATERIALS & CONSTRUCTIONbeginner
Definition
Calcium silicate board — a non-combustible board product made from Portland cement, silica, and reinforcement fibres, used as interior wall cladding, partition infill, and shaft linings in buildings requiring fire resistance. Kalsiboard is heavier and more brittle than gypsum board but offers superior fire and moisture resistance, making it suitable for wet areas and fire-rated partitions.
Example
An Indonesian hospital uses kalsiboard for all corridors, ward partition walls, and kitchen enclosures — the non-combustible board meeting fire code requirements while its moisture resistance prevents mould growth in the humid tropical environment.
