What does the term glazing refer to in the construction industry?

The term glazing in the construction industry specifically refers to the installation of a pane of glass in a window. This is a critical aspect of building design, as glazing not only allows natural light into a space but also provides insulation and contributes to energy efficiency. High-quality glazing can improve a building's thermal performance and reduce energy costs.

While painting (option A), insulating materials (option C), and protective coatings for countertops (option D) are relevant to construction and design, they do not pertain to the definition of glazing. By understanding glazing as it relates to windows, professionals in the field can appreciate its role in both aesthetics and functionality within architectural projects.
