This detail shows specially shaped sash block being used at the vertical control joint, to allow for insertion of a preformed gasket. The gasket is a rigid material, allowing in-plane shrinkage of the block, while providing some resistance to lateral loads. There is horizontal joint reinforcement at 16″ o.c. vertically in the wall, interrupted at the CJ. The detail shows optional vertical reinforcement and grout at the cells adjacent to the CJ, as well as sealant & backer rod.
