Formerly: SIL seal / Back-up Rods Bonding for assured strength with DURArods. DURArod 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.
Backup Rod
- 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
- Pre-cast panel joints
- Coping joins
- Contraction joints
- Expansion joints
- Back-up to sealants in structural glazing systems
- Glazing joints
- Isolation joints
- Dynamic joints in masonry
- Window and door frame perimeters
- Control joints
