Easy-form® Joint Isolation & Filler Foam
Proper joint design is critical for building envelope performance, and backing rods play an essential role in achieving optimal sealant profiles while preventing three-sided adhesion.
Sekisui Foam Australia offers the construction industry's most comprehensive backing rod range, from breathable open-cell polyurethane for applications requiring vapour transmission to closed-cell polyethylene for complete weather resistance. Our range covers diameters from 6mm to 50mm, ensuring the right size for every joint dimension.
Our Easy-form and Lightlon backing rods are engineered for specific performance requirements. Open-cell variants provide over 90% compression recovery while allowing air circulation, making them ideal for tilt-slab construction and applications where moisture vapour transmission is required. Closed-cell options offer superior weather resistance with water absorption below 0.4 mg/cm² and compression recovery of 95% at 50% compression, perfect for curtain wall systems and external glazing applications. Temperature stability from -40°C to +80°C ensures consistent performance across Australian climate conditions.
Beyond backing rods, our expansion joint systems include self-adhesive options that eliminate traditional paper removal, reducing installation time and ensuring consistent adhesive coverage. With service lives exceeding 25 years for physically cross-linked variants, these products provide long-term accommodation for joint movement while maintaining weatherproof seals.
