Lintel across a control joint
I am looking at installing a window in a wall where there is a control joint in the brick veneer. The best location for the window, far and away, is with the jamb in line with the control joint. This will mean that the lintel with have to span the joint. I have read that the lintel needs to be set solidly in the wall that the window sits in, and allowed to 'slide' in the other wall. Has anyone done this before? Can someone describe or show a practical approach to this? My many google searches have returned rather limited results.
