For over 60 years, Sekisui has been at the forefront of thermal and acoustic insulation innovation. Thermobreak, developed in Australia in 1987, has become a global success story, with our revolutionary physically cross-linked foam technology now protecting buildings, infrastructure and transport systems worldwide.
Physically Cross-linked. Performance Perfected.
We didn't just improve existing insulation - we revolutionised it. Our pioneering physically cross-linked polyolefin technology, developed by Sekisui Chemical, created a superior cell structure that delivers an industry leading thermal conductivity, exceptional vapour resistance, and unmatched durability.
Our proprietary physical cross-linking process produces smaller, more evenly distributed cells, that maintain performance for decades. The result? Insulation that others are still trying to match. While competitors catch up to yesterday's innovation, we continue pushing the boundaries and setting new benchmarks in performance.
But technology means nothing without real-world solutions. From preventing condensation on ducts and pipes, to meeting the strictest rail safety standards, our innovations solve actual challenges. Every product is engineered for conditions specific to your environment, and backed by our comprehensive technical support.
