Timber cladding, timber decking, saunas

Description

Redwood Thermowood timber cladding is produced by heat treating selected Scandinavian Pine, changing the chemical and physical properties of the timber and transforming it into a product with Class 2 durability (BN EN 350). This thermal process enhances the chemical and physical properties of the timber, providing a range of important benefits including greater durability and stability with no toxic chemicals or additives.


Thanks to its strength and mould resistance combined with excellent thermal qualities, Redwood Thermowood timber cladding is a natural choice for cladding. It is also suitable for use in a range of outdoor applications subject to wet conditions, including decking. A harder and knottier wood than cedar, Redwood Thermowood darkens to an attractive deep brown and will weather over time to a silver grey appearance in areas where atmospheric pollution is low. The timber can be cut and used without requiring additional treatment.


Features and benefits:

  • Physical structure: Non-structural, small sound knots.
  • Working qualities: Stable, tangential movement 2 – 3 mm.
  • Suitable for factory coating.
  • Modified timber: Thermally modified.
  • Wastage: 15-20%, due to brittleness
  • Knots: Variable.
  • Movement class: Small.
