Abstract
Abstract The window ventilator and noise insulator has three panes of glass alternately arranged high and low to leave low and high air vents. The window frame (1) is placed in the opening frame (2) and two exterior glass panels (8, 9) are arranged high in removable (for washing) frames (6, 7), to leave vents (10, 11). The central glass panel (4) is low to leave a high vent (5), so that air can follow the arrows (13, 14, 15), while the low vents can be closed by valves (17, 18) worked by levers (19, 20).
