Product Overview

Thermo-treated Poplar S4S Boards are a great way to update your space indoors and outdoors and highlight the special care that has gone into your property. Thermo-treated wood is a natural pure wood material, which was treated under extremely high temperatures 400 degree F. Due to the molecular changes that occur in the process wood became durable for at least 25-years even in outdoor applications and stable (doesn’t shrink and swell, reduced warping and cracking under changing of moisture conditions). The thermo-treatment process enhances the woods color creating an even brown tint that is consistent beyond the surface. Chemicals are never used, so the timber is 100% Green. Thermo-treated S4S boards add character and warmth to any residential or commercial application. Usage of thermo-treated hardwood increases the value of your home or business estate. Use our Thermo-treated Poplar S4S Boards indoors and outdoors, even in bathrooms and in other high humidity areas, use them for home design and for commercial applications, use them as decoration or for construction, for cabinetry work, shelve frames, deck and other utilitarian uses. Our boards are also great as a trim for other thermo-treated products like 3D Holey Wood wall panels or Holey Wood Reclaimed wood ceiling tiles.

Questions & Answers


Is there any reason not to use this wood inside? I noticed an odor but read it can go away with ...

Asked by Handymanwife June 11, 2018

You may use thermo-treated wood as usual wood. As we burn resins and sugars in the wood, the fresh wood may have some natural odor, which disappears over the time. You may use any wood finish for thermo-treated wood as for non-treated wood. For countertops usually used epoxy to make surface durable and stronger than wood.
