Architectural glass is glass that is used as a building material. It is most typically used as transparent glazing material in the building envelope, including windows in the external walls. Glass is also used for internal partitions and as an architectural feature. When used in buildings, glass is often of a safety type, which include reinforced, toughened and laminated glasses.

A facade or façade (pron.: /fəˈsɑːd/) is generally one exterior side of a building, usually, but not always, the front. The word comes from the French language, literally meaning "frontage" or "face".

In architecture, the façade of a building is often the most important from a design standpoint, as it sets the tone for the rest of the building. Many façades are historic, and local zoning regulations or other laws greatly restrict or even forbid their alteration.
