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.
