Scrap wood is a collective term for various types of wooden planks that are released during the renovation or demolition of buildings. Most common is roof boarding, but wood from facades or outdoor furnishings is also sporadically available. It is mainly demolition contractors who sell this wood, which they recover from their sites. This is usually pine or spruce, but sometimes more special batches are also available. For parquet and plank floors, see the category “Interior finishing wood”.
