Abstract

A window frame wherein all of the frame members are formed with the same identical cross-sectional configuration as, for instance, in an aluminum extrusion. A spacer is slidably inserted into the frame member which is to be the lower-most frame member when the window frame is installed to allow for insertion of a windowpane. Each frame member includes means whereby the frame can be secured to the appropriate structural members of a building.
