Abstract
Movable partition systems comprise a movable partition. A track may be configured to engage with the movable partition such that the movable partition is extendable along the track. A first mass of intumescent material may be positioned adjacent the track on a first side of a gap defined by the track. A second mass of intumescent material may be positioned adjacent the track on a second, opposing side of the gap defined by the track. At least one shroud may at least partially surround the track and may be configured to confine expansion of the first and second masses of intumescent material toward one another across the gap. An intumescent material may be sandwiched in a gap between a leading end of a lead post at a distal end of the movable partition and a cap at least partially surrounding the leading end to define the gap.
