Quality application of gypsum board begins with and depends on correct installation of an acceptable substrate. If the surface to which the gypsum board is attached is improperly or inadequately constructed, or if it is fabricated with substandard materials, the potential for an unacceptable gypsum board application will exist.
This article will examine the three systems most commonly used as gypsum board substrates: wood framing, metal framing and solid-surface systems. Desired characteristics of each will be considered and discussed.
