The gypsum panels include a gypsum core having a first surface and a second opposed surface and a first fiberglass mat associated with the first surface of the gypsum core, such that gypsum from the gypsum core penetrates at least a portion of the first fiberglass mat.
Claims20
A method of making a gypsum panel, comprising:
- depositing a first gypsum slurry onto a first surface of a first fiberglass mat, such that the first gypsum slurry penetrates at least a portion of the first fiberglass mat;
- and
- allowing the first gypsum slurry to set to form at least a portion of a gypsum core,
- wherein the first gypsum slurry comprises a latex binder in an amount effective to increase water resistance of the gypsum panel.
1 more element
A gypsum panel, comprising:
- a gypsum core associated with a first fiberglass mat having a continuous barrier coating, the coating penetrating a portion of the first fiberglass mat opposite the gypsum core,
- wherein at least a portion of the gypsum core penetrates a remaining fibrous portion of the first fiberglass mat such that voids in the first fiberglass mat are substantially eliminated, and
- wherein at least the portion of the gypsum core comprises a latex binder in an amount effective to increase water resistance of the gypsum panel.
