Claim:
1. A wall structure comprising: a plurality of vertical stud members horizontally spaced from each other to form a wall framing structure; an elongate metal strip having a body member and a projection extending outwardly from the body member, the metal strip being attached to at least two adjacent vertical stud members; a first sheathing panel having an edge; a second sheathing panel having an edge, wherein the first and second sheathing panels are disposed such that the edges of the first and second sheathing panels are adjacent each other and define a joint therebetween, wherein the metal strip is disposed such that at least a portion of the projection is disposed in the joint between the first and second sheathing panels, and wherein each of the first and second sheathing panels consist essentially of: a vapor permeable insulating panel having a primary surface opposite the plurality of vertical stud members; a layer of porous reinforcing material substantially covering and adhered to the primary surface of the vapor permeable insulating panel; and wherein the layer of reinforcing material is adhered to the primary surface of the vapor permeable insulating panel with and at least partially embedded in a water-resistant, polymeric elastomeric material that is a vapor permeable air barrier material having a water vapor transmission rating of at least 1 perm and an air permeance of less than 0.004 cfm/sq.ft. under a pressure differential of 0.3 inches of water.
