In its natural state, plaster consists of the water of formation bound in the form of hydrates. When subjected to warm or fire, this water is vaporized, over a variety of temperatures from 80 to 170 C (176 to 338 F) (see calcium sulfate), hampering warm transfer up until the water in the plaster is gone.

Type X is generally the material chosen to create walls and ceilings that are required to have a fire-resistance ranking.

The size of the examination wall setting up alone is not the only consideration for firestop examinations.
