Cambia by Greenleaf recently joined Purewood in the market for wood preserved with high heat and without hazardous chemicals. The companies have competing products, as well as competing claims for the significant energy use during production.
PureWood is a thermally modified wood decking that achieves decay resistance and dimensional stability through a process that exposes the wood to very high temperatures and steam, rather than chemicals. Although totally natural, it is energy-intensive to produce.
