System Description
With the AT 550 SK/PA system, the frame and sashes are multi-chamber profiles connected with corner brackets. With the opening mechanism (shear), in addition to being a parallel top-hung outward window it can also be turned into a top-hung outward projecting window, and offers easy installation as a facade insert element. So these window systems can be used in any mulltion and transom constructions of our system house to ensure an elegant and harmonious look.
