What’s WR-Tech… to you?

WR-Tech is a patent-pending water repellent technology that gives you the superior performance of stone wool, while providing the lowest possible water absorption at operating temperatures in the full CUI range (up to 250°C / 482°F) – also after heating and aging.

Only ProRox stone wool products contain WR-Tech.

This is how we help you optimize your plant:

  • Lower risk of corrosion under insulation (read about the CUI challenge)
  • Reduced thermal losses and an ensured continuous process operations
  • Minimized total maintenance costs

Did you know that our performance in water absorption of <0.2 kg/m2, will stay the same, also after a system is heated and aged?
