A gypsum board having glass fiber reinforcement. The glass fiber has sizing promoting bonding with a gypsum matrix. The glass fibers are added to the gypsum matrix cia a non-woven glass fiber mat bonded initially with a dissolvable or reversible binder to maintain the three dimensional architecture of the non-woven glass fiber mat during handling and insertion into a cast wet gypsum slurry forming a gypsum board.
