Definitions

• the present invention relates to a method of installing a set of ceiling panels to a basic ceiling to obtain a suspended ceiling.
• Suspended ceilings are generally known m the art. In most cases suspended ceilings are installed by use of a grid of metal beams m the form of inverted T-sections to support the ceiling panels.
• the panels used m known suspended ceilings are of various materials, such as mineral fibres, fibreglass, wood, metal, gypsum, plastic or other compositions. They are positioned within the grid opening, and are supported by the grid. The panels are either of the type that expose the grid when the ceilings are viewed from below, or conceal the grid either fully or partially, when viewed from below.
• a panel for a suspended ceiling with exposed grids normally has the form of an upper lip extending over the top of the grid with no lip on the panel below the grid. The panel hangs from the grid, by resting on this upper lip.
• Such panels are relatively simple to install, position and remove. These panels are not intended to be locked by themselves to the grid. Therefore there is a certain risk of teething" of panels during the installation, because the panels are easily pushed out of position.
• Panels that conceal the grid from below pose special problems, since the portion of the edge underlying the grid interferes with the positioning, and removal of the panels and make the installation complicated and difficult.
• Panels that conceal the grid are in general desirable for among other benefits their appearance due to stable positioning, as well as their ability to lock the grid.
• the grid can be partially or totally concealed. Additionally, since the panels of this type conceal the metal grid, they can have a beneficial effect during fire, as they serve to insulate the metal from transferring heat, particularly where panels are of a fire retardant material.
• Panels locked to the grid which give no visual clue to their removal procedure, also provide a degree of security against unauthorized access to the space above the ceiling.
• a ceiling panel for use in a suspended ceiling is disclosed.
• the panel is for use in a grid formed of inverted T-section beams.
• the panel has opposing active parallel edges each of which has a profile different from the other, having at least two opposing passive edges. All the edges of the panel have lower lips to conceal the grid when seen from below.
• the active parallel edges are formed with special designed kerfs which define an upper and lower lip in the edges and makes it possible to install and remove the panel from the grid without the use of tools.
