Rock Mineral Wool - DRS BOARD


Insulation boards for multipurpose, acoustic and thermal insulation doors

Knauf insulation DRS BOARD (DRS B) is a rock mineral wool board with horizontallyoriented fibres, specifically designed and used as an insulation core in multipurpose doors with thermal, acoustic and fire protection. Due to its good sound absorption and sufficient fire protection properties, it can also be used also for T30 fire-screen doors.
The board may be further processed (ensuring minimum dimensional deviations, surface grinding, dust removal, cutting of specific shapes) upon request.



  • Good fire resistance
  • Material melting point above 1.000 °C
  • Non-combustibility
  • Dimensional stability
  • Precise thickness dimension tolerances
  • Various combinations of insulation characteristics (sound, fire, thermal, climate insulation) possible
