ABSTRACT:
Although utilizing an inverted T-bar suspension grid, this ceiling system presents a continuous decorative relief pattern that is visually uninterrupted by T-bars. To this end, each ceiling panel consists of a thin plastic sheet molded to form a three-dimensional decorative relief pattern of symmetric design. The T-bar flanges are covered with thin plastic facing strips having repetitive geometric design elements relief molded therein. Each ceiling panel also includes a molded peripheral shoulder recessed from the adjacent panel surface by an amount at least equal to the combined thickness of the T-bar flange and the facing strip. When the panels are supported by the grid with the recessed shoulders seating on the T-bar flanges, the facing strip design elements align with the symmetric relief pattern of the ceiling panel to present a visually uninterrupted decorative ceiling.
