Historically, the term millwork applied to build elements made specifically from wood. During the “Golden Age” of mill working (1880–1910), virtually everything in the house was made from wood. During this time, the millwork produced in the United States became standardized nationwide. Today, the increase in the use of synthetic materials has led many professionals to consider any item that is composed of a combination of wood and synthetic elements to also be properly defined as millwork. This includes products that make use of pressed-wood chips in the design, such as melamine coated shelving. Read more about mill working here.
