Abstract
Hybrid nonwoven mats are made by depositing a slurry of fibers and water onto a fibrous web and applying a binder onto the hybrid nonwoven mat formed therefrom. The fibers are sized and present in an amount such that the binder forms a substantially continuous film on the hybrid nonwoven mat. Gypsum panels may be faced with a hybrid nonwoven mat on one or both surfaces.
