The tilted position could be a partial opening to ventilate the building without any danger of a person having the ability to come in through the window or opening it from outside. A normal open window typically causes a draft as a result of the direct path of surface wind flow into the room. With the help of tilted window, the outside air is channelled through the room sides of the window, whereas hotter air escapes through the highest. You can leave the window tilted open even throughout the rains. In the turning position the window opens fully. During this position, the glasses are often clean on either side from the inside of the building without dangerous stretching or climb. A quarter-turn of the handle opens the window absolutely; another quarter turn can tilt the window.
