Product Overview

KNOTWOOD

Knotwood is aluminum that looks and feels like wood only it’s lighter, stronger, greener and safer than real wood. Knotwood allows you to still have the natural beauty and timeless appeal of wood combined with the capabilities of aluminum. Knotwood uses a state of the art sublimation process to create wood like aluminum that’s greener, safer, stronger and easier to use than wood. From traditional warm woody hues to dark modern ashes, Knotwood has the most extensive range inspired from the natural world.
