Royal Ind Neo Backer Rod is a high-quality closed-cell polyethylene foam rod designed for use in expansion joints. Acting as a joint filler, it supports elastomeric sealants by maintaining optimal depth, shape, and performance while preventing sealant displacement during joint movement.
The Neo Backer Rod is water-resistant, non-gassing, and compatible with all elastomeric sealants. It is suitable for non-traffic-bearing joints and is commonly applied in buildings, roads, bridges, and other construction projects requiring reliable expansion joint systems.
This versatile backer rod ensures that sealants perform efficiently by acting as a bond breaker and joint profile former. Its compressible nature allows easy installation and excellent compression recovery for long-term durability.
