Thermowood Ash Decking

Do you prefer wood from local forests to hardwoods? Ash wood is made similarly durable as hardwoods and suitable for outdoor use through a thermal process at over 170 °C. During this process, the cell walls of the wood are changed so that they can hardly absorb any more water. 

  • Durability class 1-2 (very durable)
  • Thanks to thermal treatment, resistant to mould and fungal attack
  • Hairline cracks, shelling and splinters possible in the surface
  • Differences in colour emphasize the natural character.
