ABSTRACT:
Synthetic doors composed a rectangular frame with of skins of compression molded sheets secured to opposite sides of the frame and a core of foamed plastics with a window light therein are improved with a novel glazing cleat for securing a window light in an aperture in such a door that includes plate that rests against edges the skins about the aperture, the plate having an upright rim engaging a face of a window light and downwardly directed flanges which, with tangs on a retainer member having a upright tab engaging the opposite face the window light when nesting with the plate sandwiches the skins between the flanges and tangs to take advantage of the mechanical strength of the skins. Further if a fire resistant plate is married to internal face of each skin, the cleat will take advantage of the mechanical strength of such plates in supporting the window light in the case of fires, even if the outer or exterior skin or skins are turned to ash by a fire. For increased fire resistance the core is formed of a fire resistant foam, such a phenolic foam.
