Manufacturers also provide appropriate termination and transition accessories for their
joint systems. Figure 6.24 details a combination system at a floor-to-wall intersection.
Note the requirement for additional counter flashing to be installed.

Vertical expansion joints
Most systems discussed thus far are also manufactured for horizontal uses. These include
premanufactured metal and plastic expansion and control joints. Typical details of ribbed
and smooth vertical expansion joints are shown in Figs. 6.25 and 6.26.
Installations of stucco wall systems usually allow no dimension greater than 10 ft in any
direction and no area larger than 100 ft without control joints being installed for thermal
2
movement. Joints also are installed where there are breaks in structural components behind
stucco facades.
