Foam Backer Rod

Product Details:

Backer Rod 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. Backer Rod (back-up rods) is used as back-up to sealants to expansion joints and structural glazing systems.

Features :

• 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

Applications :

• 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
