SUPALUX® is a non-combustible calcium silicate board reinforced with selected fibres and fillers. It is formulated without inorganic fibres and does not contain formaldehyde.

SUPALUX® is off-white in colour and has a smooth finish on one face with a sanded reverse face. SUPALUX® can be left undecorated or easily finished with paints, wallpapers or tiles. SUPALUX® is resistant to the effects of moisture and will not physically deteriorate when used in damp or humid conditions. Performance characteristics are not degraded by age or moisture. SUPALUX® is also produced as bevelled edge panels for suspended ceilings using a concealed grid system
