ABSTRACT:
The panel includes a fibrous glass board, a channel-shaped metal frame, and decorative fabric or plastic film adhered to the lower surface of the board and frame. The frame has an upper flange cooperable with an inverted T-bar of a suspended grid and a lower flange which extends halfway across the head of the inverted T-bar in the mounted position of the panel. Each pair of adjacent mounted panels covers the T-bar therebetween. The board is supported mainly by tabs on the frame. Because the bottom of the board is flush with the bottom of the frame, the frame is unnoticeable behind the decorative covering. The adherence of the decorative covering to the board and frame reduces potential sagging of the board and permits the panels to be made larger.
