Backer Rods are primarily used in expansion and contraction joints. They limit sealant depth, help the sealant assume an optimum hourglass shape to prolong its life, and act as a bond breaker to prevent bottom-side adhesion.
Demand Products also offers backer rods in various shapes and diameters, including cylindrical rods, half rounds, quarter rounds, trap rods, tri-rods, sheets, and rolls.
We also offer several specialty backer rods for 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.
