HBR Backer Rod

Manufactured by Nomaco, Inc.
Brand: HBR Backer Rod

HBR® is a closed-cell polyethylene foam backer rod used in building and concrete construction. It is comprised of closed cells and an impervious outer skin completely eliminating moisture intrusion. It is typically compressed approximately 25 percent to fit tightly into the joint and function as a bond-breaker to prevent back-side adhesion of the sealant. It is commonly used in applications such as concrete expansion, construction and contraction joints, curtain wall construction partitions, wall panels, parking decks, roadway and bridge construction. HBR® is chemically inert, and therefore is physically and chemically compatible with virtually all known cold-applied sealants including self-leveling types. Sealant compatibility should be confirmed by the sealant manufacturer. HBR® fully complies with ASTM C 1330, Type C and ASTM D 5249, Type 3 physical property requirements.
