Thermally Modified Wood

"No toxins? No plastic?

No kidding. Thermally modified wood

may be the best thing since sliced cedar."

Creating Thermally Modified Wood

The process of thermal modification is accomplished with a heat and steam process.  This process actually dates back to the age of the Vikings.  They discovered that burning the surface of wood made it more durable and excellent for exterior use.  Europeans have been perfecting the thermally modified wood process over the past century, incorporating steam into the heat process.  By doing so the wood can be heated to extremely high temperatures which alters the makeup of the wood's structure making it extremely resistant to rot, decay and mildew.  This is all done without the use of chemicals.

One of the biggest problems with most outdoor structures is that, over time, the wood breaks down and begins to rot which can lead to insect damage.  The Thermal Modification process removes all sugars and tannins making the wood inedible to microbes and insects which virtually eliminates any chance of rot or decay.  This is extremely important in wet climate areas or for products associated to hot tubs and pools which can create high moisture levels.  Unlike treated lumber and cedar, thermally modified lumber is not affected by moisture.

Caring for thermally modified lumber is similar to cedar.  Staining will enhance the beauty of the wood and keep it from graying out.  Staining also reduces surface cracking that can occur on any outdoor wood product.
