Abstract: Modular Construction elements are characterized by a variety of profiles and associated interchangeable components and/or inserts. Together, these structures and components allow the end user to incorporate dissimilar or similar materials having a wide range of thicknesses and geometries into a flanged associated with the construction elements and tailored to its particular profile. Through the use of a unique set of interconnection methods and systems, a relatively small set of elements can be arranged to protect the surfaces of a wide array of interior surface treatments and the intersections of those surfaces. Dimensional material can be configured to provide the desired form of intersection and transition type—e.g., horizontally to horizontally, horizontal to vertically, vertical to vertical, vertically to horizontally, and the like—while at the same time creating and maintaining a sealed, sanitary and watertight condition within a specified area.
