A COMPOSITE TERMITE BARRIER (10) COMPRISING A MESH SHEET (13) AND TWO MEMBRANES (15, 25) BONDED TO OPPOSED SIDES OF THE MESH SHEET TO PROVIDE STRUCTURAL RIGIDITY. IN THE ARRANGEMENT ILLUSTRATED, THE MESH SHEET (13) IS WOVEN WIRE MESH COMPRISING STRANDS 17 COOPERATING TO DEFINE OPENINGS 19 IN THE MESH. THE MESH SHEET (13) FUNCTIONS AS AN ACTIVE TERMITE BARRIER THAT IS, THE MESH SHEET IS CONFIGURED TO EXCLUDE THE PASSAGE OF TERMITES THERETHROUGH, AND THE MEMBRANES (15, 25) PROVIDE SUPPORT FOR THE SHEET TO PREVENT IT FROM DISTORTING TO AN EXTENT THAT IT WOULD NO LONGER PROVIDE AN EFFECTIVE BARRIER TO TERMITES.
