Window Identification

Most windows consist of two primary components; a frame and a sash. The frame, which is the portion attached to your wall, has two side jambs, a head jamb and a sill. A sash, which is the part that holds the glass, is made up of two horizontal rails and two vertical stiles that surround the glass. Sash may be operable or stationary. Direct set windows consist of a frame and glass – no sash component – and are always stationery.

On every window there are glazing beads - small strips of wood that secure the glass in place. Windows may also have optional grilles (sometimes called muntin bars). These may be grilles between the glass (GBG), true divided lites or simulated divided lites. Simulated divided lites are permanently affixed to both the interior and the exterior of the glass to give the historic appearance of true divided lites while maintaining today’s energy efficiency requirements.
