The space (10) between the two glass layers (4,8) is closed at the bottom. A water tap (18) is positioned at the lower end of the inner wall (8). A window (2) can be opened in the upper area of the inner wall. For cleaning, water (24) containing cleansing material is filled between the two walls and a transversally positioned rotating brush (32) is moved along the panes. The water (24) can be removed with the tap (18). A blind (33,34), joined to the upper area of the wall (8), can be inserted through the window (20) into the space (10) between the walls (4,8). There are several versions of operation modes available.
