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?

Award-winning WR-Tech™ technology to combat CUI finds its way into newest generation of ProRox wired mats

Only two years ago ROCKWOOL Technical Insulation unleashed its innovative WR-Tech water repellent technology in mandrel wound pipe sections to help the industry get to grips with corrosion under insulation (CUI). Since then, plenty of plant owners have been convinced, engineers have upgraded their specifications, while contractors and installers have frequently applied this solution in new-build and maintenance projects. We also won the 2019 NACE Corrosion Innovation Award.

What does NACE* say?

NACE on CUI

NACE paper

“Because CUI is a product of wet metal exposure duration, the insulation system that holds the least amount of water and dries most quickly should result in the least amount of corrosion damage to equipment.” - National Association of Corrosion Engineers - NACE SP0198-2017 (2.1.2)
