Abstract: A tile system for use on a grid of a suspended ceiling comprises a plurality of tiles, each said tile having a main body having an exposed side and a concealed side, the exposed side defining a main surface, the concealed side defining a rear plane, and four side surfaces between the exposed side and the concealed side of the main body, wherein two of the four side surfaces have at least one tongue in the rear plane, and two other of the four side surfaces have at least one groove open to the rear plane. Fasteners, such as clips, are configured for attaching the tongues of one of the tiles to upside-down T channels of the grid, such that the rear plane of the tile is against a downwardly facing surface of the T channels of the grid.

Abstract: A laminated panel comprises a core layer and two fusible layer portions. The core layer has an upper surface. The fusible layers each have an upper surface with a surface finish and a lower surface. The lower surface of the first fusible layer portion is secured to the upper surface of the core layer, exposing the first surface finish. The lower surface of the second fusible layer portion is secured to at least one of the upper surface of the core layer and the upper surface of the first fusible layer portion, exposing the second surface finish. The two fusible layer portions are positioned side by side and are fused to be coplanar. A method for laminating panels is also provided.
