Two faces profile - T&G V-joint on one side and T&G Ship-Lap on the other side. 


Siding is four sides factory oiled (no needed additional oiling after installation).


The thermo-treatment process uses extremely high temperatures - 400 degrees F with no chemicals added. It changes wood on a molecular level to make it durable and dimensionally stable. The treatment burns poly-sugars and makes wood water repellent on a molecular level; therefore thermo-treated wood is naturally durable and stable. The color of the wood is consistent beyond the surface.
