Understanding Fire-Stop Joints: Dynamic Head-of-Wall
AIA Chicago, 35 East Wacker Drive, #250
When installing a fire wall (for example a UL U419 system) the wall has been tested for a certain hourly rating. This tested system accounts for a static wall environment, with NO movement at the floor/roof above. Typically, our walls have a deflection requirement at the top, or “Head of Wall”. Since our floors/roof will move up and down, depending on many factors, the joint at the head of the wall is no longer static; it is dynamic and will cycle up and down many times during its life. This is why we need a fire joint system at the “head of wall” that has been tested for this type of movement in order not to compromise the fire wall under building movement stress. This presentation will discuss all aspects of a dynamic head-of-wall fire stopping joint and explain how to calculate, choose, and specify the correct head-of-wall fire stopping tested assembly(s) and further examine and understand the documentation that comes with a tested fire joint system or an engineering judgment.
