Prefabricated plates for making decorative ceilings

摘要

The ceilings are made from prefabricated plates formed by assembling visible covering sheets (1) under an insulation surface or plywood plate when insulation is not considered necessary. The prefabricated plates rest inside rabbets made in the upper part of regularly spaced wood sections (2) with the exact width of the plates. The wood sections are fixed on spaced beams (6) and perpendicular to them.
