Abstract
A door seal system is provided for forming a seal between a closed door and its door frame. The system includes a unitary co-extruded seal member having first and second legs connected by a flexible hinge. A traditional flexible seal is formed along one leg and, preferably, a strip of intumescent material is formed along the other leg. The member can be folded flat along the hinge line for rolling into a compact storage and shipping configuration. For installation, a length is pulled from the roll, cut off, bent into a right angle along the hinge, and fixed to the door frame with one leg extending along the jamb and the other extending along the stop. The flexible seal bears and seals against the outside face of a closed door and the intumescent strip is positioned in the gaps between the door edges and the door frame.
