Naturally rugged. Forged in fire and steam.

 
 
 

Grit meets grace with Knotty Nordic™ ThermoWood® — real wood with real character, built to handle the elements.

 
 

Sourced from the dense forests of Northern Europe, Knotty Nordic™ ThermoWood® is crafted from spruce and pine and thermally modified using only heat and steam under a strict performance-based protocol — no chemicals, just consistent results. This process enhances the wood’s dimensional stability and resistance to rot, making it a standout choice for both interior and exterior applications.

 

With its natural tone and signature grain, it adds rustic beauty to any space — from cladding and soffits to ceilings and saunas. Certified by the International ThermoWood® Association and sourced from responsibly managed forests, it's wood you can feel good about, inside and out.
