Rigid Foam Solutions for the Fibreglass Industry
Foam Cores Designed for Composite Strength
Rigid polyurethane and polyisocyanurate foams are widely used as core materials in fibreglass structures. At Southern Urethane, our foams are engineered to maintain high strength and stiffness while keeping weight to a minimum — making them ideal for sandwich panel construction and vacuum infusion processes.
Our foam cores bond exceptionally well with fibreglass resins, offering excellent adhesion and resistance to delamination. Whether you’re building large molded components or precision panels, our products help you achieve structural integrity without compromising design flexibility.
Precision-Cut Custom Blocks
For fibreglass mould-making, plug construction, and tooling, accuracy is everything. That’s why Southern Urethane offers custom-cut foam blocks to match your exact dimensions and tolerances. Our rigid foams can be CNC-machined into complex forms, providing a reliable base for mold surfaces or structural patterns.
These foams are thermally stable and resistant to distortion, making them ideal for long-lasting tooling in high-temperature fibreglass processes. We work closely with manufacturers to deliver shapes and sizes tailored to your specific workflow and production timelines.
