The photos in this posting illustrate gypsum board (vinyl) partition as the store for pharmaceutical goods. The store needs to be air-conditioned 24 hours a day, clean and dry.
Gypsum board partitioning system was used to construct the wall as the surrounding / environment is dry ( no contact with water ) and the wall would not be taking heavy loads.
In a nutshell, it is much faster to use gypsum board to construct the partition / wall ; there are no hacking of walls to build the partition and the partition can be dismantled later on without damaging the floor and ceiling upon which the partition is positioned.
