Everything you need to know about thermally modified timber

Thermally modified timber is wood that has been treated using high heat (between 160-240°C) in a controlled, oxygen-free environment. This process permanently alters the wood's cellular structure, improving its durability, stability, and resistance to decay without the use of chemicals.

  • Exterior cladding and siding
  • Decking and outdoor flooring
  • Garden furniture and structures
  • Window and door frames
