For example, see cable tray movement in a German test. In the case of regular gypsum board, as drywal crystalline water is driven off, the reduction of volume within the gypsum core gjproc large cracks to form, eventually causing the panel to fail due to loss of structural integrity. This setting has far less shrinkage than the air-dry compounds normally used in drywall, so it only requires one coat.

Scrubbers use the technique of flue-gas erywall FGDwhich produces synthetic gypsum as a usable gyprroc. Fire Protection Fire safety: Continued use of this site indicates that you accept this policy.

This typically results in deflection of the assembly towards the fire, as that is the location where the sublimation occurs, which weakens the assembly, due to the fire influence.
