Fire Resistance

FireKem FP-900® has superior fire resistance performance and the boards are approved for up to 240 minutes fire resistance according to BS 476: Part 22: 1987 depending on application.

Dimensional Stability

FireKem FP-900® has excellent dimensional stability under elevated temperatures and in severe moisture environments.

Moisture Resistant

FireKem FP-900® will not deteriorate when used in damp or humid conditions and will not encourage mould growth. The boards are also rot proof.

Performance characteristics are not degraded by age or moisture. Untreated surfaces will absorb water, which can cause some loss of strength, but full strength is regained after drying.

Chemical Stability

FireKem FP-900® is a chemically inert calcium silicate board, unaffected by contact with most chemicals and resistant to dilute acids and alkalis.

Acoustic Performance

FireKem FP-900® provides good acoustic reduction performance of between 26-49dB. It also provides thermal conductivity (approximately) at 20°C of 0.17 W/mK.

Easy Workability

No special equipment is required for cutting or drilling of FireKem FP-900® boards. It is recommended that cutting of the boards is carried out in well-ventilated situations, or the wearing of suitable dust masks to reduce the hazard of nuisance dust production, during the cutting or drilling process.

Boards may be flat head nailed or pilot drilled, then screwed.

Smooth Surface

FireKem FP-900® has a smooth surface but due to their high suction should be first sealed prior to applying paints, plasters, or wallpapers.


FireKem FP-900® is a lightweight but strong building board. System performance is unaffected by the hazards and condition of its working environment it does not rot.

Vermin Resistant

FireKem FP-900® boards remain unaffected by rodent, termite and insect attack.
