BACKER ROD MATERIAL AND JOINT CONSTRUCTION FOR BUILDING COMPONENTS

摘要

An efficient and reliable installation for a water tight and an aesthetically pleasing transition between adjacent building or construction components is provided with use of a backer rod material for placement between adjacent building or construction components for subsequent caulking. A closed cell foam backer rod material includes a terminal end portion of the backer rod joined to a remainder thereof by a frangible connection or perforated joint. The frangible connection or joint in the backer rod is nonlinear or arcuate-shaped to provide a crown- shaped or convex-shaped backer rod surface to receive the caulking compound to finish the joint. After the backer rod material is installed into the joint, the terminal end portion of the backer rod is removed by being torn along the frangible joint. A bead of caulk or similar finishing material is applied in the recess to provide a smooth and aesthetically pleasing transition from the frame to the wall. The convex or crown shape of the exposed surface of the backer rod material allows for and promotes integrity of the caulking compound during shifting, expansion and/or contraction of the adjacent building components relative to each other.
