Abstract: A modular temporary barrier system includes a plurality of panel members having adjoining edges. Each panel member comprises a foam core and exterior sheathing disposed thereon. Connecting structure associated with the panels is constructed and arranged to removably connect adjoining edges of adjacent panel members to one another. Each panel member includes joint structure forming an aperture extending vertically between an upper periphery of each panel member and a lower periphery of each panel member that is configured to receive the connecting structure.

Abstract: A modular temporary barrier system includes a plurality of panel members having adjoining edges. Each panel member comprises a foam core and exterior sheathing disposed thereon. Connecting structure associated with the panels is constructed and arranged to removably connect adjoining edges of adjacent panel members to one another, such that connected panel members together form a wall. In preferred embodiments of the invention, each panel member and two one-piece corner members each comprise a foam core and exterior sheathing disposed thereon. Each corner member can be removably connected to a respective end of the wall. In other preferred embodiments of the invention, the modular barrier system can further include two side panel members, each side panel member being able to connect to a respective end of the wall such that the wall is self-supporting.
