This backer rod is a flexible, non-gassing, bi-cellular, pliable back-up material for construction joints and applications requiring sealants. It acts as a depth control for most cold-applied sealants and also helps the sealant assume the optimal hourglass shape. Sealants will not adhere to it; no bond breaker is required. That is why flexible backer rod is a popular choice.

Flexible backer rod is particularly suited for applications with irregular and varying joint widths where standard closed-cell backer rods are not appropriate and where bubbling issues are critical. Flexible backer rod can also be used in place of standard closed-cell backer rod in most applications.

Common applications for flexible backer rod include expansion and contraction joints, window glazing, curtain wall construction partitions, parking lots, bridge and highway construction pavement maintenance, and log home chinking.
