What is a Damping Pad?

A damping pad is a preformed laminated fabric pad of manufactured material composed of layers of tightly twisted, closely woven lightweight material.  Each layer is made up of an elastomeric compound containing mold and mildew inhibiting agents.

What is it Used For?

Because steel smoke stacks have relatively low inherent structural damping, excessive top-of-stack deflection can result at critical wind speeds due to vortex shedding.  To keep these deflections within acceptable limits, a damping pad is placed between the stack base plate and concrete foundation and conforms to the exact shape and size of the base plate.
