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 desired thickness of sealant at the joint’s centre. It does not bond with cold applied sealants. DURArods (back-up rods) is used as back-up to sealants to expansion joints and structural glazing systems.
