Abstract: A corner stud (40) has a four-sided post portion (42) that sits into a corner region of a framing wall. The post portion includes a pair of flanges (92, 96) which form a right angle inside corner at the inside corner of the framing wall. Edge portions of wallboard panels (108, 110) connect to the flanges (92, 96). A post portion 112 of an intersection stud (110) fits within the tracks at a location between the corners. Inside corners are formed by flanges (148, 160) and (154, 166) against which edge portions (180, 182) of wallboard panels (184, 186) and (188, 190) are connected. The edge portions (180, 182, 188, 190) of the wallboard are connected to and backed up by the flanges (148, 160, 154, 166).
