    摘要: A dead stop type projection window assembly includes a free-standing frame and at least one insert window. The free-standing frame includes a top member, a base member spaced below the top member, at least two mullions vertically extending between the top member and the base member and spaced apart to form an insert window opening therebetween, and a stop extending along a perimeter of the insert window opening. The insert window is secured to the free-standing frame at the insert window opening and is sealed at the stop with sealant to close the insert window opening. The free-standing frame also includes a sealant dam extending from the stop and engaging the insert window to resist flow of the sealant toward the window frame opening between the stop and the insert window.
