Aluminum external window sills serve as drips of Al openings on the outer envelope of the object, and their main function is to protect the parapets in the area of windows and doors, prevent precipitation from entering the window frame and water leaks on the facade. In order for water to drain, the outdoor sills must be installed with a slight slope to the outside. On the outer part, the sills are bent for easier dripping and greater strength, and the bent part can be 25 or 40 mm high. Aluminum sills are made of extruded aluminum, and their service life is practically unlimited. The choice of colors of the outer sills is determined by the RAL and Elox card, so that the aluminum bench can be plasticized and anodized according to the opening on the object itself. The sills come in standard delivery lengths of 6000 mm, so they can be adjusted to any required dimension. Placing Al side plugs on aluminum sills ensures quality drainage of water from the wall and façade. Joining two or more aluminum sills into one unit is performed using the original coupling elements, i.e. the couplings of the benches.
