Abstract
The present disclosure relates to plaster boards and methods for making them. For example, one aspect of the disclosure is a plaster board comprising one or more continuous layers of material disposed within a body of hardened plaster material, the first side and second side of each continuous layer of material being substantially covered by the hardened plaster material. In certain such embodiments, each continuous layer of material includes a polymer (e.g., a damping polymer) disposed on a carrier sheet. Another aspect of the disclosure relates to a method for making a plaster board that involves drying a wet body of plaster material while a continuous layer of material or precursor therefor is disposed within it.
