The present invention is directed to an improved gypsum board, such as an improved sound damping gypsum board, and a method of making such gypsum board. For instance, the method comprises: providing a first encasing layer and a first sound damping layer on the first encasing layer wherein the sound damping layer includes at least 50 wt. % of a first sound damping polymer; depositing a gypsum slurry comprising stucco and water on the sound damping layer to form a gypsum core; providing a second encasing layer on the gypsum slurry; and allowing the stucco to convert to calcium sulfate dihydrate.

Sound damping gypsum board and method of constructing a sound damping gypsum board

The present invention is directed to a gypsum board and a method of making such gypsum board. For instance, the gypsum board comprises a gypsum core, a first facing material, and a second facing material wherein the first facing material and the second facing material sandwich the gypsum core. The gypsum core comprises a first gypsum core section and a second gypsum core section each comprising gypsum, wherein the first gypsum core section comprises a polyol compound and has a density higher than a density of the second gypsum core section.

Gypsum board containing a polyol compound

Provided are wallboard panels that include a foam material layer and a core material, with one or more sheets of facer material and/or one or more sheets of backing material. The foam material layer may include one or more pores having an open pore geometry. Additionally, provided are methods of manufacturing such wallboard panels.

Wallboard with foam material layer

Provided are cementitious panels that include a cementitious core material and a plurality of sheets of facing material surrounding the cementitious core material, in which at least one of the plurality of sheets of facing material includes a polymeric-film. The polymeric film may include a thermoplastic composition that has a polymeric matrix including one or more polymeric materials. Additionally, the thermoplastic composition may optionally include a filler material. Additionally, provided are methods of manufacturing such cementitious panels.
