What is the minimum thickness required for a wall constructed from solid gypsum plaster with specific lathing requirements?

The minimum thickness required for a wall constructed from solid gypsum plaster is typically specified to ensure structural integrity, fire resistance, and sound insulation. A thickness of 2 inches provides sufficient mass to enhance these properties. Solid gypsum plaster, when applied over lathing, requires a certain minimum thickness to effectively bond and perform as intended in a commercial building setting.

While thicker options may provide added benefits like better fire ratings or enhanced durability, the minimum standard indicates that 2 inches is adequate for basic construction needs, maintaining compliance with building codes and industry standards. This thickness ensures that the wall can adequately support itself and meet various performance criteria while being cost-effective.
