Abstract

The invention relates to a thermally insulated conduit pipe, comprising at least one medium pipe, at least one thermal insulation arranged around the medium pipe, and at least one outer jacket arranged around the thermal insulation, wherein the outer jacket possibly comprises a barrier made of plastic, and wherein the thermal insulation comprises a foam, the cell gas of which contains at least 10 vol % HFOs. Such conduit pipe has good insulating behavior, good environmental balance, and is easily producible.
