The sheets are produced following EN 12467:2004 standard - CE certification
The Silbonit H sheets belong to the new generation of asbestos free compressed and stabilized flat sheeting reinforced with mineralized cellulose fibres.
The sheets are non-combustible and resistant to rot, fungus and vermin attack.
Silbonit H is used in different building applications for internal and external use.
The sheets can be varnished with micro-porous alkali-resistant varnish fixed with a UV polymerizing system.
The treatment allows for the easy removal of graffiti. Because of its ease of cleaning, Silbonit can be safely used in areas where urban graffiti is a problem.
Silbonit boards are trough coloured in 12 different tonalities.
