Curtain wall facades have become a common choice in contemporary architecture, with significant technological advancements over the last 20 years, making them one of the most attractive and modern options in building design. However, it is important to highlight that these facades can develop pathological issues that compromise the durability and performance of buildings. These issues can be associated with design flaws, defects in quality control during manufacturing, transportation and handling failures, installation issues, and a lack of maintenance, all of which can affect their service life. Through a literature review and interviews with industry professionals, this research addresses the most common curtain wall construction systems in Brazil: structural glazing, single- or double-glazed curtain walls, also known as framed glazing, and stick and unitized systems. It also provides a historical context of the evolution of these facades. The study presents best construction practices and up-to-date technical standards. A case study of a commercial project in the city of São Paulo is conducted, analyzing the pathological issues that emerged during its service life and their impacts on the building's use. It is possible to identify that the pathological issues found are a result of execution process failures in the facade
