[0014] Window set for barrel roof comprising two roof windows, each with flat window frame 1 and the sash 2. Both windows in these embodiments are identical, it is not required to differentiate between the main and additional window. The window frame comprises two stiles 11, left and right, top rail 12 and bottom rail 13, all of them straight forming the flat window frame. The sash 2 of the roof window comprises a flat sash frame 21 with the flat window pane 22 specifically comprising two glass panes. Sash frame 21, specifically its stiles are joint with stiles 11 of the window frame with two hinges, at the stiles, above half of the window height. The window frame 1 comprises recesses 14 in the stiles 11 from the inside, where the hinges are installed.

[0015] The adapter frame 3 comprising two stiles 31, top rail 32 and bottom rail 33 is fixed to the window frame 1, from the attic side in accordance with this embodiment. The stiles and the rails of the adapter frame are joined with corresponding stiles 11, top rail 12 and bottom rail 13. The stiles 31 of the adapter frame comprise concave surfaces 34 opposite to the window frame, and the curvature of the concave surfaces 34 corresponds to the curvature of the barrel roof. The remaining surface of both stiles 31 and all surfaces of top 32 and bottom 33 rail of the adapter frame, are straight.

[0016] The stiles 31 of the adapter frame 3 are joined with top 32 and bottom 33 rail of the frame with screws 35. To increase the rigidity of the adapter frame, top rail 32 have splines 32a on both ends, and the bottom rail 33 have splines 33a on its ends, where the splines of both stiles correspond to the grooves in stiles, in the surfaces from the inside of the adapter frame.

[0017] The assembled adapter frame 3 is fixed to the window frame 1 with screws 36 through the stiles 31, top 32 and bottom 33 rails of the adapter frame and corresponding window frame stiles and rails. Due to an arched shape of the surface 34 in stiles 31 of the adapter frame, and variable thickness of the stiles, the length of the screws 36 fastening the stiles 31 with stiles of the window frame is variable.

[0018] All adapter frame 3 stiles and rails: stiles 31, top 32 and bottom 33 rail, at its surfaces fitting the window frame stiles 11, top 12 and bottom 13 rail have splines, corresponding to the grooves at the surfaces of the window frame stiles (Fig. 8, 9, and 10) positioned from the side of the attic. The grooves in the window frame stiles, if the window frame is mounted in a flat roof are used for setting the position of components which covers the side surfaces of the opening in the roof fitted with a window, where the components fit the window frame. To maintain the layout of the retaining surfaces, stiles of the adapter frame 3 have the edges positioned from the inside of the frame. In stiles, the edge 31 a is concave, as the concave surface 34, which it is adjacent to, and the edge 32b of the top rail and the edge 33b of the bottom rail are straight. In the installed adapter frame 3, the edges form a uniform, frame 37 pointing the attic.

[0019] The frames 1 of both roof windows are positioned between two arched rafters 4, where stiles 11 of the frames are fixed with standard angle holders, used in roof windows. Between two frames, the rafters 4 are joined with a crossbar 41, and from the inside of the attic, a support plate 42 is fastened with screws. Both adapter frames 3 are positioned on the support plate 42 and supported by the top rail of the adapter frame, positioned below the crossbar 41 and the bottom rail of the adapter frame above the crossbar.

[0020] Each of the roof windows has a set of covers 5 made of metal sheet, protecting the attic against precipitation. The covers 51 are installed over the hinges connecting the sash with the window frame, and fixed to the frame 1, and the covers 52 positioned below the hinges are fixed to the sash 2 on the sash frame 21. The set of two roof windows also has a common roof flashing 6 made of metal sheet, which with the surfaces perpendicular to the roof surface 61 fit both the window frames 1 and adapter frames 3. The flash roofing 6 with the walls fitted to the roof matching the roof curvature enters the roof covering 43 e.g. roof tiles at the section above the top window and at its sides, and the section 62 of the flash roofing is positioned over the roof covering 43. Between two windows, the roof flashing comprises a trough 63, draining the rain water from the window located above.
