Soft Backer Rod

Alcot Plastics Soft Backer Rod is a soft, non-gassing, pliable, bi-cellular backup material for construction joints and applications that require sealants. It performs as a depth control for most known cold applied sealants and also helps sealant to assume the optimum hour-glass shape. Sealants will not adhere to it; no bond breaker is required. This is why the soft rod is a popular choice.

Soft Backer Rod is especially suited for applications with irregular and varying joint widths where standard closed cell backer rods are not appropriate and where bubbling concerns are critical. The soft rod may also be used in place of standard closed-cell backer rod in most applications.

Common applications for the soft backer rod include:

  • expansion and contraction joints
  • window glazing
  • curtain wall construction partitions
  • parking decks
  • bridge and highway construction pavement maintenance
  • log home chinking
