Vendor Glass Trade Centre

Professional open cell foam backing rod for very wide joints, designed to regulate sealant depth and achieve the correct profile. The breathable structure aids curing while preventing three-sided adhesion, improving movement capability and durability. Suitable for polyurethane, hybrid, and silicone sealants across façades, precast elements, and interior joints. Compressible and easy to install, the 40mm x 30m roll is ideal for large-scale projects requiring consistent performance and reduced sealant consumption with clean, reliable tooling outcomes.
