ABSTRACT:
A fire-rated, flush mounted corner guard is provided which serves to maintain continuous integrity in the fire rating of building walls notwithstanding the recessing thereof to accommodate a corner guard and consequent lessening of the amount of fire rock present at the corner. The corner guard preferably includes an upright, continuous, floor-to-ceiling, L-shaped in cross-section synthetic resin corner cover, means for resiliently mounting the cover within a corner recess substantially flush with the building walls, and insulating means within the corner recess beneath the cover. In this way the corner guard assembly provides a fire rating substantially equivalent to the fire rating of the walls. Preferably, the insulating means includes a heat-expandable continuous ceramic insulating sheet and steel protector disposed over the insulating material and beneath the cover and which overlaps the wall outermost surfaces adjacent the corner portion.
