Fenestration is an architectural term that refers to the arrangement proportion and design of window skylight and door systems within a building. Fenestration components include glazing material either glass or plastic framing mullions muntins dividers and opaque door slabs external shading devices internal shading devices and integral between-glass shading systems. For our purposes fenestration and fenestration systems will refer to the basic assemblies and components of exterior window skylight and door systems within the building envelope. Fenestration can serve as a physical and or visual connection to the outdoors as well as a means to admit solar radiation. The solar radiation provides natural lighting referred to as daylighting and heat gain to a space. Fenestration can be fixed or operable and operable units can allow natural ventilation to a space and .
