DURA rods

‘DURA rods’ is a closed cell polymer based product with a circular profile. it ensures stronger bonding of sealant with masonry, aluminum or other substrates & helps to maintain desired thickness of sealant at the joint’s centre. it does not bond with cold applied sealants. It is used as a back - up to sealants in expansion joints and structural glazing systems.

Features & Benefits

  • Closed cell, hence negligible water / moisture absorption
  • Excellent chemical resistance - Inert to most acids and alkalis
  • Cost - effective space filler
  • Allows unrestrained expansion & contraction of sealants. Eliminates bubbling of sealant.
  • Non - staining - Reduces sealant consumption


  • Pre - cast panel joints
  • Glazing joints Isolation joints
  • Coping joints
  • Dynamic joints in masonry etc.
  • Contraction joints
  • Window and door frame perimeters
  • Expansion joints
  • Control joints
  • Back-up to sealant in structural glazing systems
