摘要： Disclosed herein are plaster boards that include first and second layers of hardened plaster material, a liner attached to the first layer of hardened plaster material, and a first material (e.g., a polymer material such as a viscoelastic polymer) adhered between the liner and the second layer of hardened plaster material. The liner includes one or more structurally weakened regions each extending substantially from a first edge to a second opposing edge of the plaster board. The structurally weakened regions of the liner may facilitate creation of a fissure that propagates substantially within a plane within the plaster board. Methods for making the plaster boards may involve drying wet plaster material while it is in contact with a liner having structurally weakened regions, processing a liner to form its structurally weakened regions while in contact with wet plaster material, or processing a liner to form its structurally weakened regions while in contact with hardened plaster material.
