What does glazing mean?

In construction and architecture, glazing refers to the installation of glass or other transparent or translucent material (such as polycarbonate or acrylic panels) into a frame, opening, or structural system. The term encompasses a broad range of applications: windows, storefront systems, curtain walls, skylights, glass doors, glass canopies, interior glass partitions, glass railings, and any other building component where a glazed unit is installed. Glazing also refers to the glass unit or panel itself, as in ‘the glazing in that window is a double-pane insulated unit.’ A glazier is the skilled trade professional who cuts, fits, and installs glass in all of these applications. The term derives from the Old French ‘glaz,’ meaning glass. Outside of the construction industry, glazing has entirely unrelated meanings in ceramics (the application of a glassy coating to fired clay) and in cooking (a liquid reduction or coating applied to food for finish and shine), but in the building trades, glazing specifically and exclusively refers to glass installation work and the glass materials themselves.
