ABSTRACT:
A fire resistant panel includes at least four parallel vertically extending sheets of gypsum. The sheets are fastened together in a spaced apart arrangement with two outer sheets and two inner sheets positioned between the outer sheets to define a member having first and second opposite vertically extending sides. Vertically extending sheets of steel are in contact with and cover both sides of the member. The upper support for the member defines a circuitous path from one side of the member to the other. A bottom seal is supported by the member and includes a weight mechanism attached to the bottom seal. The weight is pivotally movable and biases the bottom seal downwardly for engagement with a floor.
