Rock Mineral Wool - DRS FIRE BOARD


Insulation core for door sets requiring higher fire resistance

Knauf insulation DRS FIRE BOARD (DRS FB) is a high-density rock mineral wool board specifically designed and used as an insulation core in doors, whose main purpose is to provide fire and thermal protection in compliance with EN 16034 (harmonised standard for fire-rated door sets).

The mineral fibres are bound with a minimum of organic binder, ensuring board integrity at high temperatures. 

The board may be further processed (ensuring minimum dimensional deviations, surface grinding, dust removal, cutting of specific shapes) upon request. 


  • Excellent fire protection
  • Maintains integrity at high temperatures – material melting point above 1,000 °C
  • Good mechanical properties
  • Non-combustibility
  • Dimensional stability
  • Thermal and sound insulation properties
  • AS Quality (upon request)


Owing to its particular properties, the board is a highly convenient means of insulating steel fire-resistant door sets that require high fire resistance and temperature tolerances and are specified by European standards as EI30 / EI60 / EI90 fire resist
