Choosing a proper cladding system can be a key ingredient to reducing Corrosion Under Insulation (CUI)
CUI is major maintenance issue that has to be addressed by owners. A key component to reducing CUI is having a cladding system that is strong enough handle the mechanical damage brought on day-to-day. A good cladding system also maintains tight seals at overlaps and terminations and does not contribute to a breach in the underlying vapor barrier. Though metallic cladding has been the choice of many engineers and owners, there are some fundamental problems with these systems that have contributed to the CUI problem we now face. A good alternative in the CUI process range is to use a GRP system such as GRP UV cured or pre-cured. These systems exhibit superior resistance to mechanical damage as compared to metal and also offer greater potential to seal the overlap and termination joints. A UV cured GRP can also offer superior fire resistance and chemical resistance as compared to a typical metal cladding. UV Cured GRP systems have been designed and used throughout the world to help reduce CUI. From the desert of the Middle East to the frigid cold of Russia, UV cured GRP has proven time and again that it is a vital tool to reduce CUI.
