CALPEX PUR-KING boasts thermal insulation record with lowest-ever lambda value of 0.0199 W/m*K.
- The lambda value of 0.0199 W/m*K as atrustworthy average of many individual from several production lots
- Test results from independent and accredited institutes confirm the stated heat losses
- On the market since 2018, Pioneering work, patent granted
- Efficient insulation performance
- Flexible pipe laying thanks to small bending radius and low physical effort
The CALPEX PUR-KING is a patented flexible, continuous and self-compensating low-temperature pipe system boasting the world’s best lambda value of 0.0199 W/m*K. This exceptionally low value is proved and confirmed on an annual basis by an accredited test institute.
This record-breaking figure has made it possible to beat the what were previously thought to be the lowest physical thermoconductivity values for polyurethane by a significant amount. CALPEX PUR-KING is therefore becoming the trigger for another major increase in the energy efficiency of pre-insulated pipe systems for the heating and cooling market.
Over the past decade, BRUGG Pipes has been able to decrease the lambda value for the CALPEX pipe systems further and further through intensive research and development work.
With the newly developed CALPEX PUR-KING process technology, we have now succeeded in reducing the thermoconductivity of CALPEX pipes to the world’s lowest lambda value of 0.0199 W/m*K.
With this record-breaking figure, we have been able to beat the what were previously thought to be the lowest physical thermoconductivity values for polyurethane by a significant amount. CALPEX PUR-KING is therefore becoming the trigger for another major increase in the energy efficiency of pre-insulated pipe systems for the heating and cooling market.

CALPEX PUR-KING wins DTI test for fourth time in a row
Every year, the Danish Technological Institute carries out an extensive series of tests on pre-insulated district heating pipes. We are delighted to announce that, for the fourth time in a row, we came top in the flexible PEX pipe system category with our CALPEX PUR-KING. In the 4 years since it was launched on the market, we have not only emerged as the test winner but have also been the only manufacturer with consistently low values.
Forget Covadis – there’s no beating CALPEX PUR-KING!
Boasting the world’s best insulation value, CALPEX PUR-KING – with its patented PUR foam and exceptionally high Swiss quality standards – simply cannot be beaten.
Thanks to the closed-cell PUR foam, the heat loss remains almost as low as on day one – without a diffusion barrier. The extremely efficient insulating performance enables annual energy savings of up to 15% and will also help you to reduce CO2! The true king wears a crown.
