Fire blocking aims to prevent or at least slow the vertical movement of flames, smoke and gases by sealing off concealed spaces like stud cavities and soffits. Smoke and gases readily travel horizontally as well, so preventing horizontal air movement, such as within a dropped ceiling, has its own name: draft stopping.
