Caution
One limitation to walls and ceilings is
the maximum allowable temperature
the dry-wall can maintain. According
to the National Gypsum Company, the
maximum operating temperature for
wallboard and ceiling board is 125¡F.
Due to this limitation it is advised not
to allow supply fluid temperatures to
exceed 120¡F. From a design perspec-
tive, it is advised not to allow the sur-
face temperature to exceed 90¡F.
If a different wall material is to be
used, consult that product s manufac-
turer for specific temperature limits.
