Siniat Variant:

Gypsum hard board (GHB).

Jump to:

It has been designed for durability in busy, high traffic areas which are intensively used, or prone to abnormal or rough use including schools, hospitals and hotel corridors.


LaDura is an alternative to a traditional gypsum fibreboard. Made from gypsum reinforced with wood fibre, it is stronger and harder than other plasterboards giving greater impact and pull out resistance. The board combines fire, moisture and impact resistance and provides a superior finish to gypsum fibreboards.

Features and benefits:

  • High impact strength providing extended life in high traffic areas such as corridors and stairwells.
  • Good pull out resistance allows direct fixing of hung loads such as radiators and other fixtures without need for pattresses.
  • Compatible with standard metal framing helping reduce material costs.
  • Excellent fire, sound, impact and moisture performance allows specification of just one board per project.
  • Fully recyclable - with low embodied carbon, helping to reduce environmental impact.


  • Complies with BS EN 520:2004+A1:2009 Type D, E, F, H1, I and R.
  • To BS EN 1252 and BS EN ISO 12524.
