In masonry, what is the term used to describe a brick that is laid on its end?

In masonry, a brick that is laid on its end is referred to as a "header." This positioning means that the narrow face of the brick is exposed, allowing it to bond more effectively with adjacent bricks in the wall. Headers are frequently used in various applications, such as creating arches, supporting loads across openings, or simply serving as a means to enhance the structural integrity of a wall.

Stretcher, rowlock, and soldier describe different brick orientations or arrangements. A stretcher is laid flat with the longest side exposed, creating a long, slim profile. A rowlock refers to a brick laid on its face, but with the end portion visible, creating a shorter, broader profile. A soldier, meanwhile, is positioned upright with the long edge vertical, providing a tall, narrow look. Each of these terms corresponds to specific construction techniques within masonry that serve different aesthetic and structural purposes.
