Movable partition systems include a movable partition and an intumescent material positioned to seal a gap at a periphery of the partition. In some embodiments, masses of intumescent material may be shaped and positioned to expand toward one another, contact one another, and form a seal therebetween at a periphery of the partition when the movable partition is exposed to fire. A fire barrier may be provided by extending a partition along a track assembly, and heating an intumescent material to cause the intumescent material to expand, char, and form a seal extending along at least a portion of a periphery of the movable partition. Upon installing a movable partition, at least one mass of intumescent material may be positioned to seal at least a section of a gap at a periphery of the movable partition when the at least one mass of intumescent material is exposed to fire.
