IHS Pipe

Manufactured in Germany, IHS underfloor heating pipe is a 5-layer PE-RT (polyethylene for raised temperature) midi composite pipe with an oxygen barrier at its centre.  The oxygen barrier is firmly fused between the internal and external layers using an adhesive polymer, making the whole pipe a single unit.

If the oxygen barrier was on the outside it would be subject to wear and tear caused by moisture and air, resulting in silting, corrosion, cracking and possible eventual detachment of the layer itself.  The external PE-RT later of the IHS pipe protects external environmental damage.

Stress rupture tests have shown that midi composite pipe is resistant to higher pressure than those pipes without oxygen barrier.  The melting point of the oxygen barrier is more than 180°C.

Because oxygen is the primary factor that influences pipe aging, the midi composite pipe design ensures almost no oxygen exchange (oxygen permeability is below 0.01g/m³ per day, significantly below DIN4726 requirements of 0.1g/m³).

The IHS underfloor heating system runs at average of 1.5 bar with a water temperature of between 45-70°C.  IHS pipe carries a 50 year guarantee.
