An offset expansion joint and method of installing the same in a repaired or rebuilt furnace, such as a coke oven or the like, comprises at least two segments of ceramic fiber spaced laterally from one another and separated by silica bricks and a barrier of silica mortar which extends along an edge of each segment and along an edge of each of the bricks by which the segments are spaced, the silica mortar having the ability to set up when exposed to about 2200 DEG F. to prevent passage of gas through the expansion joint in the area of the horizontal flue of the coke oven.
