Mixed ceiling tile for receiving e.g. lighting system, in building, has insulating plate glued to verso face of metal frame, and non fire treated perforated wooden veneer glued to recto face of metal frame

摘要

The tile has a lacquered, folded or ergotted metal frame serving as a support, and an insulating plate glued to a verso face of the frame, where the insulating plate is made of rock wool, mineral wool and glass wool. Non fire treated perforated wooden veneer is glued to a recto face of the frame. An assembly of the frame, insulating plate and perforated wooden veneer is placed under pressure once the assembly is coated with aqueous based glue so as to permit perfect assembling. The frame strengthens behavior of the insulating plate and corrects potential variations of the veneer.
