Abstract
A method of forming a wallboard material can include forming a mixture including microparticles, sodium silicate and vinyl acetate. The mixture can be disposed between a metallic facing membrane and a second facing membrane. The mixture can then be heat cured in a single step sufficient to form a wallboard material having the metallic facing membrane and the second facing membrane attached to a core matrix. The heat curing time is complete in less than about 1.5 hours without causing damage to the wallboard material.
