Patent ID: 8444790

Claim:
A method of protecting a hollow structural tubing building component from fire damage comprising: providing a multi-layer fire protection barrier comprising a first layer comprising an intumescent material and comprising first and second oppositely-facing major surfaces, a second layer comprising a continuous reinforcing matrix, a third layer comprising a pressure sensitive adhesive and a fourth layer comprising a release liner removably adhered to the third layer; removing the fourth layer from the fire protection barrier to expose the third layer; and, wrapping the multi-layer fire protection barrier around an outer surface of the hollow structural tubing building component and applying the pressure sensitive adhesive of the third layer to the surface of the hollow structural tubing building component to adhesively attach the fire protection barrier to the hollow structural tubing building component so that the first major surface of the first layer is an exposed outer surface of the multi-layer fire protection barrier, wherein the continuous reinforcing matrix fails during a fire so as to form fragments within the intumescent material that limit fissure propagation through the intumescent material.
