After the staging is built, the new sheetrock in the ceiling and upper sections of the stairway are hung and the old sheetrock is patched. After the ceiling and upper sections are hung the lower sections are hung.
The sheetrock being used is a new lightweight sheetrock from USG.
The sheetrock on the half wall was not hung because that wall will be removed to install the new stairs.
Th picture above shows the recessed light centered in the entry opening .
Before the ceiling was hung it was insulated with 6″fiberglass insulation .
In the picture above the sheetrock joints were taped and the screw holes were filled.
