Products for
 Insulation technology

In insulation technology, functional materials with defined properties play a central role.

Lézaud offers Profiles, slides, Sheets, Hoses as well as seals and shaped parts for various applications in insulation technology.

Depending on the application, materials must be temperature-resistant, ageing-resistant, flexible and reliably processable. Based on our expertise in plastics, TPEs and elastomers, we provide targeted advice on selecting suitable solutions – tailored to technical requirements, installation situation and long-term stress.
