Overview

SOF® Rod is a soft bi-cellular polyethylene foam backer rod used in concrete construction. SOF Rod has a water-resistant outer skin and resilient interior network of cells helping cold-applied sealants assume the optimum hour glass shape to prolong the sealant service life. It is comprised of both open and closed cells that will not out-gas when the skin is ruptured preventing sealant bubbling and failure. It is commonly used in applications such as expansion and contraction joints, window glazing, curtain wall construction partitions, parking decks, bridge construction, modular home gasketing and log home chinking. SOF Rod is comprised of an inert material, and therefore, it is physically and chemically compatible with virtually all known cold-applied sealants including self-leveling types.
