It also has an extruded aluminum frame, and a double dome with sealant all around (clear polycarbonate over clear polycarbonate). The curb is a 3” (75mm) polyisocyanurate insulation, and a condensate channel with drainage to exterior. Security is a must, which is why there’s a slam latch with inside and outside handles.
