DURArods' is a closed cell polymer based foam filler material with a circular profile.

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.


·         Closed cell hence negligible water/ water vapour absorption

·         Excellent chemical resistance - Inert to most acids and alkalis

·         Cost effective space filler

·         Allows unrestrained expansion and contraction of sealants. Eliminates bubbling of sealants

·         Non-staining
