An air-vapor barrier continuity device for installation across an airspace between a window (or door jamb) and a wall stud (or rough sill) so as to provide an air-vapor barrier across the airspace. The continuity device comprises a flexible first generally rectangular longitudinal planar member and a second generally rectangular longitudinal line of the second member. The angle between the first and second members is greater than 90 DEG to provide biased contact with the wall stud or rough sill. The second member attaches to a door (or window) jamb at the inner wall surface of the jamb. The first member is of sufficient breadth to extend from the jamb across the airspace to the first wall stud (or rough sill) adjacent the air space. Preferably, the continuity device is extruded from a polymeric material as a single sheet bent along a longitudinal line, one side forming the first member and the other side forming the second member.
