[net.followup] Energy Efficient Window Design Conte

dkw (01/11/83)

One rather good system I have seen for windows is the "Window Quilt" (tm)
it consists of a quilt with some insulation and a layer of aluminized mylar
to prevent radiant heat loss.  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.
