The invention pertains to packet windows (fig.1) with top-hung casement and is intended to keep gnats and other insects out of premises. The offered netting (2) is a thin plastic net (see the pattern in Fig.3), where A stands for height of a window opening and B for width of a window. In the places intended for the net (4) a folding is made applied by hot pressing. A net has a glue stick (1) melted in the line of a perimeter in one side of which (Fig.2) places for hinges in the form of incision (3) are made. The glue stick consists of two parts. One part is attached to the basic frame of a window (5) and the other part - to the netting (2). By connecting the both parts they make a solid hold and may be easily separated, if necessary. The glue stick is intended for multiple uses. The net (2) is attached to the basic frame of a window (5) at two sides and at the top edge, as well as to the relevant sides of casement.
