Description

A range of ceiling systems comprising SUPALUX® boards and channel framing to provide ceilings capable of spans up to 4000 mm.

SUPALUX® is a strong and rigid non-combustible calcium silicate board designed to provide fire resisting ceiling constructions. Non-coated calcium silicate boards can be left untreated, or decorated with water or oil-based paint, paper or vinyl, plaster or decorative renders. Note that the surface spread of flame properties may be negated when the boards are decorated.
