Durolight® S1


Durolight® is a new developed insulating composite material especially designed to meet the thermal and mechanical requirements of load bearing supports. Durolight® is manufactured from a special formulation of selected synthetic resins in combination with high-strength glass reinforcements.



  • Glass-reinforced thermoset SMC high-pressure laminate developed for applications at cryogenic temperatures
  • Low thermal conductivity and low weight

Application Examples

Insulating load bearing pipe supports

Durolight®, a fibre reinforced insulating composite was designed and developed to meet the thermal and mechanical requirements of load bearing supports in LNG applications. The very low thermal conductivity and ability of this material to operate in environments with temperatures from 196 °C to +200 °C (-320 °F to 392 °F) make it an excellent choice for insulation of pipelines and also for use as thermal breaks within the Oil & Gas industry. Durolight® is naturally flame retardant & halogen free, resistant to weathering, abrasion and wear. With these exceptional properties having led to Durolight® being approved by such companies as Bechtel Corp, Linde AG and Tractebel S.A./N.V.
