Even on most domestic roof spans it will be impractical to obtain a ceiling joist member in one length. It will also be necessary, unless very large ceiling joists are used, to support the ceiling joist at some point along its length, by suspending it from the structure above and/or on a structural wall below. Figure 3.1 shows the typical solution using hangers and binders. More information on a typical hanger and binder combination for supporting the ceiling joists can be found in Chapter 5.
