In its members, the window frame has walls made of a material with a low thermal conductivity, preferably a plastic, situated along the support flashing, transversely to its surface resting on the roof. These walls are situated at least at the side of the window sash, forming - on at least three members, the top one and both side ones - a circumferential wall surrounding the opening in the window frame. In the walls situated in the window frame members from the side of the window sash, there are longitudinal grooves, particularly with a T-shaped cross-section. These grooves serve the purpose of mounting the seals situated between the window frame and the window sash.
- Outside the walls, the window frame members seated in the roof structure, have a filling made of an insulating material, preferably a porous one, with a lower resistance than the material of the walls in the window frame, but with a higher thermal performance than the material of walls. Basically, the external surface of the filling does not require an exposure, but it may be equipped with a second wall the same type of plastic, as the wall from the side of the window sash. A variation of the frame members is also possible, where they do not have a separation of materials to a more mechanically resistant wall and a filling with improved thermal performance, but they are made of a material uniting both these properties. Grooves for the seals are then situated directly in this material of the frame members.
- In a second aspect of the invention, the structural element of the window frame connecting it with the roof is constituted by bearing strips, adjacent to the side members of the window frame, on the external side of the window. The bearing strips protrude beyond the outline of the window frame members on its opposite sides, and it may be a protrusion of the strips sideways of the window, or a protrusion along the side frame members, upwards and downwards, beyond the top member and the bottom member of the window frame. The window frame according to the second aspect of the invention has in its members, similarly as according to the first aspect, walls made of a material with a low thermal conductivity, preferably a plastic, which are situated at least on the side of the window sash, forming on at least three frame members, the top one and both side ones, a circumferential wall surrounding the opening in the window frame. In the walls situated in the window frame members on the side of the window sash, there are longitudinal grooves, particularly with a T-shaped cross-section. These grooves serve the purpose of mounting the seals situated between the window frame and the window sash. Outside the walls, the window frame members seated in the roof structure, have a filling made of an insulating material, preferably a porous one, with a lower resistance than the material of the walls in the window frame, but with a higher thermal performance than the material of the walls. Basically, the external surface of the filling does not require an exposure, but it may be equipped with a second wall of a plastic; a variation of the frame members is also possible, made of a uniform material, with grooves for the seals situated directly in this material - as in the first aspect of the invention.

In the tilting hinges, arms are seated, terminated with pivoting hinges, while both the tilting and pivoting hinges, as well as the arms connecting them, are situated on the external side of the window. The hinges according to this aspect enable using the window as a dual-action window, by opening it as a pivot window or a tilt window. During opening of the window in the pivoting mode, the window sash rotates in the pivoting hinges, as in the first aspect of the fitting, while the tilting hinges are blocked, and the arms connecting both types of hinges rest on the window frame. During opening of the window in the tilting mode, the window sash together with the arms connecting both types of hinges, rotate in the tilting hinges.
- The third aspect of the fitting belonging to the window frame is constituted by hinges for a window sash, situated near the top edge of the window, i.e. tilting hinges, in which the window sash is mounted directly. The hinges are placed on the external side of the window. The window according to the third aspect of the invention is being opened only in the tilting mode.
- In all aforementioned aspects, the window frame with a fitting may have an additional frame, preferably made of wood, situated at the internal side of the window, that is on the side of the attic. On the additional frame, elements locking the window are installed, mating with corresponding locking elements seated on the frame of the sash. These are for instance bolt sockets, mating with the bolt of the handle. On the other hand, the window frame has on its external surface, on the external side of the window, installation elements for connecting the window frame with the flashings of the window, which seals the connection of the window frame with the roof. Preferably it is an installation frame, upon which properly bent edges of the flashing of the window are laid, resting on the roof and adjacent to the window.
- Advantages of the invention. Thanks to its design enabling its immersion in the roof structure, the roof window frame with a fitting for a roof window for immersing also the sash of the roof window in this structure, increases the thermal performance of the whole window. Metal elements of the window frame, having large volume and mass, such as: hinges, support flashing, or bearing strips, are situated on the external side of the window frame, and do not have components penetrating the interior of the roof structure, or the interior of the opening in the window frame for a sash; optionally these parts constitute a small share in metal fitting subsets, so there are no thermal bridges in the window frame, which could lead to thermal losses from the attic by outflow of heat to the outside of the building.
