Answers:    if the window is used for flimsy only i.e fixed later u can remove the window frame and put together a wall of glass bricks. this is awfully secure and transmite lantern.
if u r using them i.e openable type then put aluminum frame because for crypt you cannot take likelihood as of weather.
u can take cheap agency out but then after some time enjoy to put it again so go for durable choice at lowest possible.
