An outside longitudinal corner construction of wallboard panels includes a framing member of the rectangular wooden stud or C-shaped sheet metal channel type, an edging member which is essentially T-shaped in cross-section or of a modified shape and a pair of wallboard panels fitted to the edging member and held to the framing member in such a way that a flap of covering fabric or sheet, as of a prefinished wallboard panel, or a part of the cover paper of such a panel, which cover material had the wallboard core and back removed from it, is wrapped around the edging member T cross-bar and held in position by the other wallboard panel. Thus, the edging member is concealed by the cover material, which is wrapped around it, and the corner construction matches in appearance the rest of the wallboard, with only one discontinuity along the length of the corner on one side thereof, and such is not conspicuous. Also described are edging members incorporating various improvements, such as auxiliary cross-bars, grooves, aligning projections and openings, wallboard holding means adapted to hold wallboards of different thicknesses, a rounded edge on one side of the T cross-bar and a sharper edge on the other side, and pre-deposited adhesive. Procedures for constructing the corners are also disclosed.
