The most rugged board in the forest.

Kodiak gives your project the bold allure of the backwoods. Knotted spruce boards provide natural appeal, while their extra-wide size allows for faster installation with fewer seams for a clean, modern feel. The brushed texture means you can see and feel the natural grain of the wood, adding ruggedness without sacrificing the refined look you crave.

Kodiak Spruce color transformation.

Wood’s natural aging process is influenced by how much exposure it has to the elements. The more Kodiak Spruce is exposed to UV light and rain, the faster its color will transform from brown to silver—sometimes in as little as six months. To maintain your wood’s natural color outdoors, simply treat the boards with a penetrating UV protective oil.

Thermally Modified

Heat. Steam. Cool. Done.

Thermal modification is a chemical-free process that gives you the beauty of real wood, naturally enhanced with only heat and steam for unequaled strength and stability—even in changing weather conditions. And with greater insulating properties compared to unmodified wood, our wood is never too hot on your feet.
