FIELD: civil engineering, in particular, windows designed for installation on the roof. SUBSTANCE: the window has a frame having the upper member, lower member and two side members that are tied together by angular joints, as well as a great number of mounting brackets. The side members and the upper and lower members of the frame in the mounted position of the window are located essentially in parallel with the roof strikes and the roof batten members respectively in the roof construction. Each mounting bracket has the first supporting part designed for joining the frame member linked with it, and the second supporting part that is perpendicular to the first supporting part and designed for attachment to the roof construction, each mounting bracket is made in the form of a try square, where the first supporting part is made in the form of two supporting sections perpendicular to each other and designed for joining to the adjacent frame members in the joint between them. EFFECT: optimized rationalization of the mounting process. 16 cl, 6 dwg
