Figure 1-1. Box sills
b. T-Sills. There are two types of T-sill construction-sills commonly used in dry, warm climates
(see Figure 1-2) and sills used in colder climates (see Figure 1-3). Although these T-sill constructions are
similar, notice that in Figure 1-2 the joists are nailed to the studs and sole plates. In Figure 1-3 the joists
are nailed to the studs and sills and headers are used between the floor joists.
