What is Arbor Wood Co?

Arbor Wood Co. is the new and innovative choice in modified wood applications. Produced from the abundant North Central forests of the USA, Arbor Wood Co. (AWCo) offers innovative thermally modified timber for a variety of outdoor and indoor applications, from housing installations to decorative fixtures and product components. AWCo Thermally Modified Timber (TMT) joins regionally harvested wood, a value-added heat-modification process, and local Minnesota milling to bring finished TMT goods to a variety of markets and uses.

What is Thermally Modified Timber?

Thermal Modification is a process that replaces the use of chemicals to enhance an inapt wood species performance with heat and steam so it is suitable for a multitude of applications indoors and out. The high heat modifies the cell structure of the wood and makes it highly resistant to rot while greatly reducing expansion and contraction. Through multiple cook temperatures, a range of color options within a single species can be achieved without the use of stains.

Aesthetically, the wood is darkened in color, and it brings an unexpected tropical look to more-commonly lighter indigenous wood species. Since Thermally Modified wood does not absorb or hold moisture as it would prior to treatment, species that typically do not perform well in outdoor or wet environments can now be used as decking or siding.
