best wood WALL 140 pre-plastered Pre-plastered wood fibre insulation board

The pre-rendered WALL 140 is a pressure-resistant wood fibre insulation board pre-rendered with adhesive and reinforcing mortar (UP) for installation on full-surface and load-bearing solid wood substrates. It should be fixed with the help of broad back staples. 


  • Part of the under plaster layer of approx. 4 mm as groove structure already applied in the factory
  • conforms to approval in best wood ETICS
  • can be exposed to weather for up to 5 months
  • Time saving: no tooth filling on the construction site, no drying time required
  • saves set-up and working time on the construction site
  • high-quality: uniform layer thickness, due to machine application
  • Reinforcement fabric with security in the right place
  • easy to cut and install
  • prevents lignin from bleeding through
  • 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 installation - secured by our processing guidelines ETICS

For your and our safety, we take great care to ensure a high standard of quality.

Simple cutting and installation

The pre-plastered WALL 140/180 boards are cut to size using cutting equipment such as hand-held circular saws and sliding table saws with hard-metal blades.The fixation of the best wood WALL 140/180 is carried out using of broad back staples or alternatively with the screw-in anchor H35.

Economy of time

  • One working step on the building site can be omitted, since there is no further need to put the notched plaster onto the board
  • No drying time since the board already comes pre-plastered
  • Saves set-up and working time on the building site
  • An outdoor exposure of up to 5 months is possible

High Quality

  • Thanks to the machinery coating, the whole layer has the same thickness
  • This assures that the reinforcement fabric is fixed at the right place in the second step
  • Avoids the penetration of lignin
