When we first started installing Thermally-Modified Poplar on the exterior of a prominent and high profile project, we had people stopping to ask "What is that? It's beautiful!" To say that the exterior of the building is stunning is an understatement.
So what is Thermally Modified Wood? It is a process of heating the wood to over 400 degrees to remove the organic compounds from the wood cells. Water is not absorbed by the wood, it will not expand or contract or provide nourishment for insects or fungi. The result is a durable wood product that is permanently resistant to water, insects and decay.
The heating process also gives the wood a deep, rich chocolate brown appearance. Unfinished, this naturally ages to a gray color in a similar way to cedar shingles as they age.
