best wood ROOM 140 Plaster baseboard for internal application

ROOM 140 is a plasterable wood fibre insulation board for internal walls. It can be fixed on masonry, walls of solid wood and wooden wallboards with planking (e.g. OSB).


  • Pressure-resistant plasterable wood fibre insulation board for interior use with a weight of 140 kg/m³
  • Excellent thermal conductivity value
  • Good heat protection in summer and optimal thermal insulation in winter
  • Improves sound insulation: wood fibre insulation boards are very good sound insulators, the higher the raw density the better the sound-insulating effect
  • Hydrophobic throughout
  • Open to diffusion and therefore moisture regulating
  • Easy to install - backed up by our ROOM 140 processing guideline
  • Hardly any waste due to the fact that the boards can be used on both sides
  • Completely recyclable
