masonry control joints
(OP)
I am mainly inquiring about how vertical control joints are installed at wall openings when a masonry bond beam spans/extends across the opening. How is a vertical CJ installed?
I have a small addition 50' x 30' that utilizes reinf. cmu behind a stone veneer and inside finish is mtl. stud/drywall, so the reinf. cmu is never visible. The 50' span has many door, window openings.
Thanks

What I have encountered is control joints located at the end of a masonry lintel above the opening and then it turns toward the opening at the bottom of the lintel. The edge of the opening provides the movement below the lintel.
In other words, the control joint jogs around the lintel so as not to interrupt the lintel. Haynewp is right, the lintel will have to support the entire weight of the wall above if near a control joint.
