Backer Rods are primarily used in expansion and contraction joints. They limit the depth of the sealant, help the sealant assume an optimum hourglass shape factor to prolong its life, and serve as a bond breaker to prevent the sealant’s bottom-side adhesion.
Demand Products Backer Rod is also available in various shapes and diameters, including cylindrical rods, half rounds, quarter rounds, trap rods, tri-rods, sheets, and rolls.
In addition, we offer several specialty backer rods for use in fillet joints and shallow joint reservoirs. Demand Products backer rods are commonly used in joints for curtain wall partitions, bridge and highway construction, parking decks, pre-cast assemblies, glazing applications, and panel systems.
