Abstract
Abstract A surface panel is secured to a frame by means of flaps or tabs to form a structural unit without face-exposed fasteners in its field area. If desired surface-exposed fasteners may even be eliminated from the peripheral area of the panel. In a further improved version a complete vapor barrier which also acts as a field securing means is provided.
