Treatment of ceiling
The ceiling differs according to the structure of the building. For details, consult your architect.
In the process after the ceiling panels have been removed, it is important to reinforce the ceiling construction and ensure the ceiling
remains in a horizontal position. This is to prevent possible vibration of the ceiling panels.
