Thermally treated timber has undergone first a kiln drying process and afterwards a thermal treatment for up to 48 hours and 260 degrees Celsius meaning it's chemical free and makes it durable and resin-free.
This process modifies the cellular structure of the material and will prevent degradation via insect attack, rot, weathering etc for many decades.
The process changes the colour of the timber to various shades of brown depending on material, our Scandinavian redwood fifths end up a nice light chocolate brown.
If the colour is protected by a clear coating for external use then the colour will remain the same but if left alone it will change to a lovely silver grey over time. Internally the colour will not fade for many years and will require no treatment to retain it's original brown hue.
This is a highly durable material that is effectively a drop in replacement for tropical hardwoods with far lower environmental impact.
