26.3 BRICK VENEER WITH<br />
A STEEL STUD BACKUP WALL<br />
CHAPTER 26<br />
EXTERIOR WALL CLADDING<br />
The construction of brick veneer with a steel stud backup wall differs from that of a CMUbacked<br />
wall mainly in the anchors used for connecting the veneer to the backup. Various<br />
types of anchors are available to suit different conditions. The anchor shown in Figure<br />
26.25 is used if the air space does not contain rigid foam insulation so that it is fastened<br />
to steel studs through exterior sheathing.<br />
The anchor shown in Figure 26.26 is used if rigid foam insulation is present in the air<br />
space. The sharp ends of the prongtype anchor pierce into the insulation (not the sheathing)<br />
and transfer lateral load to the studs without compressing the insulation.<br />
