Abstract: A window frame includes a plurality of horizontal and vertical frame members each having glazing legs with angled exteriorly facing sides that overlap at the corners and substantially flat planar inwardly facing glazing surfaces against which a glazing element is set in place, with bedding compound between the glazing element and glazing surfaces to adhere the glazing element to the glazing legs. Pockets extending substantially the entire length of the glazing surfaces provide for the positive, accurate location of a continuous bead of bedding compound on the glazing surfaces and control the amount of the glazing compound that is squeezed out between the glazing element and glazing surfaces when the glazing element is set in place to insure a watertight seal around the entire perimeter of the glazing element.
