Treatment of ceiling
The ceiling differs according to structure of building.
For details, consult your constructor or interior finish
contractor.
In the process after the ceiling board has been
removed, it is important to reinforce ceiling foundation
(frame) and to keep horizontal level of installed ceiling
correctly in order to prevent vibration of ceiling board.
1. Cut and remove the ceiling foundation.
2. Reinforce the cut surface of ceiling foundation, and
add ceiling foundation for fixing the end of ceiling
board.

Matching to the existing structure, set pitch according
to size in the unit external view as shown below.
