High performance in high or low temperatures.

Thermal performance in materials is key in applications involving extremes of temperature - high and low temperatures. Choosing the right composite is critical to avoid unnecessary maintenance and downtime.

We have more that twenty composite products each built for specific thermal durability and mechanical requirements. Our materials partner Rochling are global experts and able to develop bespoke materials.



Where you can find our materials


Where high strength is required in cryogenic applications, foam materials aren't up to the task.

Composites are used is high load bearing situations to support pipes, valves, motors, and other components that are at cryogenic temperatures.

Our Durostone and Lignostone materials provide a range of grades and mechanical properties to handle different loads and application demands. Each has very low thermal conductivity to minimise thermal energy flow that contributes to costly energy losses and degradation of the base structure.



For high strength and high temperatures up to 800°C we have tough materials that can handle the heat.

Many of the same materials we use in low temperature are just as suited to high temperature applications, though only up to around 200°C. This includes our Durostone polyester glass and epoxy glass range.

Above this temperature we transition to silicone materials with glass or mica as the mechanical strengthener. These remain non-toxic, non-flammable and with excellent thermal resistance and stability.



Key Properties
