Panels of drywall are fastened either directly to the ceiling joists or to a few layers of moisture-proof plywood which are then attached to the joists. Pipework or ducts ...
In tests, standard curtain wall systems are typically able to withstand up to three inches (76 mm) of relative floor movement without glass breakage or water leakage. Snow load. Snow loads and live loads are not typically an issue in curtain walls, since curtain walls are designed to be vertical or slightly inclined. If the slope of a wall ...
the floor of 1.4 is 1, the ceiling of 1.4 is 2. 1.6 rounded is 2, the floor of 1.6 is 1, the ceiling of 1.6 is 2. So the floor of a fraction is always down; the ceiling of a fraction is always up; rounding can be up or down depending upon whether the fraction is less
The height of the Central Hall ceiling made this a complicated and expensive process, requiring floor-to-ceiling scaffolding across the length and width of the Central Hall. [93] The need to avoid damage to the fragile mosaic flooring and the terracotta tiling on the walls caused further difficulty in erecting the scaffolding. [ 94 ]
