For this example (see Figure 1), the wall type is defined as a partition. As previously discussed, in drywall construction, a partition is defined as a single row of framing with gypsum board applied and finished on both sides of the framing. This wall, in all its variations, meets that criteria. At first glance, it appears that there are two basic types of wall here, one- and two-hour rated, with the stud size providing most of the variation.
