organic material
Facade materials taken from naturally grown organisms and retaining a more or less natural appearance.
Organic facade materials are natural materials taken from living organisms, especially woody plants.
The material comes from naturally grown organisms. Wood and bark are existing examples of plant-derived exterior coverings.
The distinction concerns the facade substance, rather than the load-bearing material behind it. An organic covering can be attached to a framework made of another material.
