Pert pipe comes in different qualities for multiple applications, it is the most commonly used pipe for underfloor heating coming in coil form only. Roth X-Pert pipe has a five layer build with an oxygen barrier, high resistance to damage and excellent performance when transferring heat.

All five layers of the DUOPEX S5® System Pipe are co-extruded and then subsequently cross-linked throughout by means of a patented production process. This ensures connections at the molecular level, not only within the individual layers but also between them. As a result, the five-layered pipe is absolutely stable. Interactive crosslinking improves the mechanical, thermal and chemical characteristics of the DUOPEX S5® System Pipe and provides additional safety reserves.

This product is only used in heating and cannot be joined with press fittings unless a repair is required. Roth pert is not WRAS approved.

The alternative to pert is MLCP which has WRAS approval and can be used for in most situations.

ROTH DUOPEX S5® and X-PERT S5®+ System Pipes can all be used with the Roth Original Tacker® System, the Roth Knob System and the Roth Pipe Fixing System for heating and cooling purposes.

ROTH DUOPEX S5 ® Design meets the most stringent requirements.  A continuous stress of 95C at an operating pressure of 6 bar and a short term increase to 110C is no problem for this pipe.

ROTH X-PERT S5 system pipe is designed with a safety plus for a continual thermal stress of 70C and a short term thermal stress of 100C. This pipe is continuously pressure-resistant with multiple safety reserves up to 6 bar.
