There is a large roller above the window and small plastic tracks running down the sides to provide an air seal to the wall. Apart from the somewhat ugly roller (generally hidden by a box-like structure) it is attractive and very effective. David Wittenberg ...decvax!brunix!dkw ...ucbvax!vax135!brunix!dkw
