This presentation will examine recent window and curtain wall assembly failures and performance issues for Insulated Glazing Units (IGU), aluminum coatings, gaskets, and associated water and air leakage issues. With the advent of globalization in the construction industry, façade glazing systems are beginning to experience new types of failure in the components (seals, coatings, sealants, etc.) used to assemble the complex systems and result in performance issues of today’s high rise projects. Various components and systems will be examined regarding their potential for air and water intrusion, coating issues, glass breakage and/or IGU failure.
