Thermally Modified Wood

Arbor Wood is thermally modified wood produced in a specialized, 3-phase kiln chemical free process using only heat and steam. An initial gradual increase in temperature reduces the equilibrium moisture content (EMC) of the wood. Phase 2 sees a rapid spike in temperature and is where the magic really happens. The cellular composition of the wood is altered in this high-heat, oxygen-deprived environment which converts the natural acids and sugars so as to no longer be a food source for mold, rot or fungal decay. This change also renders the wood ‘hydrophobic’, meaning it loses much of the natural tendency to absorb water going forward. As a natural byproduct of the process the wood takes on a richer, dark tone throughout giving it a look similar to that of exotic species. The 3rd and final phase introduces steam to cool the wood down and bring the EMC back up to a suitable level.

Thermal modification is one of the most natural, chemical-free ways to extend the life of wood products.

Properties

  • Dimensional stability is increased, minimal expansion and contraction

  • Enhanced appearance: darker, through-color and more even tone throughout

  • Increased exterior performance: less water absorption and less susceptible to rot

  • Able to be glued, painted, finished

  • Milling and workability similar to standard wood

  • Lightweight

  • Process is chemical free, only heat and steam are used

  • Is a value-added, new application for domestic wood

Where to use

Thermally modified wood can be used in an array of commercial and residential applications. Popular applications are in external environments where moisture and humidity would compromise a lesser-grade material.

  • DECKING

  • DOCKS

  • SIDING

  • INTERIOR FLOORING

  • WINDOWS

  • DOORS

  • BATHROOM INTERIORS

  • SAUNAS

  • OUTDOOR FURNITURE
