A fenestration is provided having a peripheral frame defining a frame opening, the frame being adapted to being installed upon an opening in a building panel. Cooperating with the peripheral frame is a laminated panel which is structurally mounted to and sealingly spans the peripheral frame opening to form a structural and leak proof interconnection. The laminated panel is formed of three structural layers; an outer and inner plastic sheet and a resin layer interposed therebetween which are collectively bonded together to form a structural laminate, the laminated panel being capable of transmitting visible light therethrough.
