The board is universal and multifunctional suitable in the roof, the wall, the facade and the floor.


A high-performance pressure-resistant, vapour permeable, natural and ecological thermal insulation board based on wood fibre. The board edges from 140 mm thickness have a rebated finish to avoid thermal bridges. The board has excellent sound insulation properties due to the porous structure.

Features and benefits:

  • Pressure-resistant, universal and multifunctional.
  • Excellent at insulating against thermal losses in winter and heat transmittance in the summer.
  • Possesses excellent sound-insulation properties.
  • CE marked.
