: The silicone would seal the window from the outside weather. The stained glass panel would sit against the inner aluminum lip for some air exchange (due to no caulk).
Little to air will exchange by not caulking the inside. If the 2 glazings touch then the air can not circulate. It just stays put. As I said you need a space of 1/2" to 1" between the 2 glazings and holes are needed at the top and the bottom of the window on the inside for heat and mosture to escape.
