摘要

A ceiling system in one embodiment includes a grid support member including a flange defining a bottom surface and a ceiling panel supported by the grid support member. A first facing sheet includes a peripheral edge portion attached to the grid support member. An integral cutting guide groove is formed in the bottom surface of the grid support member. The peripheral edge portion of first facing sheet includes an edge which is axially aligned with the groove. A second ceiling panel includes a second facing sheet including a peripheral edge portion having an edge axially aligned with the groove and disposed adjacent the edge of the first facing sheet to form a seam. The first and second facing sheets conceal the grid support member. A related method of installation is disclosed.
