Description
Extra-large open cell backing rod engineered for very wide joints in façades and civil works. It controls sealant depth, prevents three-sided adhesion, and allows adequate curing in deep joints. Compatible with polyurethane, hybrid, and silicone sealants. The compressible foam is easy to cut and place, improving tooling and reducing sealant use. The 50mm x 20m roll is suited to major expansion joints and detailing where robust joint geometry is essential for long-term, movement-capable sealing performance in harsh environments.
