What is Fenestration?

The literal meaning of Fenestration (from the Greek word ‘Fenestra’, which means ‘window’) is “the placement or arrangement of exterior windows and doors.”


While this is a more formal definition, the industry includes both indoor and outdoor windows, as well as doors, skylights, and other openings that provide light or passage from one space to another. However, the fenestration market isn’t just for manufacturers of these systems. It also extends to manufacturers of the components that are used to make them. For example, this could be any of the following and more:
