PRAXAO works out the ceiling area, then the plasterboard with its furring, hangers, screws and jointing compound, or the lay-in tiles with the exposed grid and its hangers. The drawing shows the ceiling in 3D, in plan with the frame, and in section. Board and tile sizes, spacings and waste are starting values to replace with your supplier’s data.
