Because the veneer and backup in a brick veneer assembly are made of different materials and are exposed to different temperature variations, they expand and contract at different rates in their own vertical planes. Therefore, the anchors that connect the veneer to the backup should allow these movements to be unrestricted. Can this requirement be met by using one -piece anchors? If not explain,
why not?
What will be an ideal response?
Because both the veneer and backup move in their own vertical planes only, i.e., up and down and sideways, the anchors must be made of two pieces to provide that flexibility, which is not possible with a one -piece anchor.
