This boardis similar in composition to Type X drywall, except that it has more glass fibers, and, it has another ingredient in the gypsum core. This ingredient is a shrinkage-compensating additive, a form of vermiculite. When exposed to high heat, the gypsum core shrinks but the shrinkage-compensating element expands at about the same rate as shrinkage occurs in the waterdepleted gypsum. The gypsum core then is more stable in a fire and remains in place even after the combined water in the gypsum has been driven off.
