The primary purpose of horizontal joint reinforcement is to control shrinkage cracking associated with thermal or moisture. The joint reinforcement increases a wall assembly’s resistance to horizontal bending. There are many different types of joint reinforcement. Product selection is based upon whether the wall is single wythe or multi-wythe, and if the assembly is vertically reinforced. Consult with your joint reinforcement manufacturer on what material to use.
