Claim:
A fire barrier operable to span a gap between two surfaces, each surface including a top face and a side face, and to impede the spread of fire and smoke between the surfaces, the fire barrier comprising: a first base member constructed from extruded aluminum and coupled with an uppermost portion of the top face of one of the surfaces; a second base member constructed from extruded aluminum and coupled with an uppermost portion of the top face of the other surface; a covering member constructed from extruded aluminum and monolithically formed with the base members to span the gap; an intumescent sheet extruded onto polyethylene film and having a plurality of edges which are attached to the support structure; and a unitary support structure comprising a fiberglass scrim directly coupled with the intumescent sheet and having opposed planar flanges extending generally parallel with a horizontal portion of the surfaces spanned by the joint cover system and operable to directly couple with the surfaces and the first base member and the second base member, the support structure being larger in at least one dimension than the intumescent sheet.
