ABSTRACT:
A fire resistive joint cover system operable to span a gap between two surfaces. The system generally may include first and second base members, a covering member, and an intumescent sheet. Each base member is operable to couple with one of the surfaces and the covering member is operable to couple with the base members to at least partially span the gap. In some embodiments, the covering member may be configured as a floating covering member and/or as a flexible elastomer seal.
