Thermo 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.
ADVANTAGES
- 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.
