Wall facing having V-shaped channel-like folds

Claim 1

A wall facing comprising: a relatively stiff though flexible facing sheet having normally front and rear sides and a rearwardly reentrant generally V-shaped channel-like fold extending from one edge to the opposite edge of the sheet and defining at opposite sides of the fold a pair of adjacent panel sections, each fold having confronting side walls formed by portions of said sheet and integrally joined to and projecting rearwardly in converging relation from the adjacent edges of the adjacent panel sections and integrally joining one another rearwardly of said panel sections to form a flexible hinge portion along the centerline of the fold at which said facing sheet may be bent to a folded configuration wherein the junctures of each fold side walls with the adjacent panel sections abut one another and the adjacent panel sections are disposed in substantially mutually perpendicular relation to conform to a corner formed by two facing sheet mounting walls, said facing sheet having a substantially uniform thickness throughout said panel sections and each fold, each panel section having outer edges along the edges of said facing sheet and integral rearwardly extending mounting flanges along said outer edges for seating against the mounting wall surfaces, the adjacent edge portions of each pair of adjacent panel sections sloping forwardly at a small angle from the planes of the sections as said edge portions approach the intervening fold, and said sloping edge portions being devoid of said mounting flanges and said junctures of the walls of each fold and the adjacent panel sections being arcuate in cross-section and arching toward one another beyond the fold side walls whereby said edge portions bend to an arcuate configuration and said junctures abut to form a forwardly opening recess along the fold for receiving a sealant such as grout when said facing sheet is bent to said folded configuration.
