Abstract
A window sash member is composed of a pair of rail members and a pair of vertical sash members or stiles which may each include a framing element having a unique cross-sectional configuration. The sash member is so constructed as to permit replacement of glass panes without destroying the integrity of the frame. This is accomplished by removing a series of glazing strips. A hollow defined within the framing element provides the rails with a reinforcing member which has fins to minimize undesired thermal conduction across the frame. A downwardly open recess is defined within the framing element so as to permit it to be employed with a wide variety of window frame elements and adapting it for use in a wide variety of types of windows. The rails are preferably joined to the stiles by welding. The sash framing element is particularly adapted to be used with insulated windows having two or three panes of glass which define a thermally insulating dead air space therebetween. The sash framing elements are preferably composed of a synthetic resinous material.
