Flexible pre-insulated pipe 

RAUVITHERM is a pre-insulated PE-Xa pipe for district heating, biomass, biogas and heat pump applications. It has proved immensely popular since its launch due to its high flexibility and easy to use REHAU EVERLOC™ jointing system.

In our constant drive to reduce our carbon footprint, REHAU manufactures RAUVITHERM in the UK. The pipe is supplied in project-specific lengths to reduce any wastage on site.

RAUVITHERM is available in UNO 25-125mm and DUO 25-63mm.
