A highly compressed silica-cement sheet reinforced with mineralized cellulose fibres. The sheets are non-combustible and resistant to rot, fungus and vermin attack.

Primarily intended for use as interior and exterior cladding and lining, but can also be used for applications such as flooring and balconies.

Sheets are available in a range of colours and can be painted with alkali resistant paints and varnishes to match particular colour requirements.
