Backer Rod

Formerly: SIL seal / Back-up Rods Bonding for assured strength with DURArods DURArods’ is a closed-cell polymer-based foam filler material with a circular profile. It ensures stronger bonding of sealant with masonry, aluminium or other substrates & helps to maintain a desired thickness of sealant at the joint’s centre. It does not bond with cold-applied sealants. DURArods (back-up rods) is used as a back-up to sealants to expansion joints and structural glazing systems.
