Insulated double-walled pipe

Our insulated GEROthen® double-walled pipe consists of a GEROthen® PE 100-RC pressure pipe on the inside, an insulation layer of PUR and a GEROblanco sewer pipe on the outside. It is suitable for use in trenches but also for free laying, e.g. for a bridge undercrossing. The thickness of the insulation layer can be adjusted according to the customer’s wishes or specific requirements. Optional trace heating ensures additional, lasting protection.

A wide range of moulded parts and accessories complements the pipe range.
