Roof window system with a ventilation unit mounted adjacent to the roof window, and a method of providing ventilation for a building

Abstract

The roof window system () is configured for being mounted in an opening in a roof structure () of a building and includes a ventilation unit () configured for being mounted adjacent to a roof window () and adapted for providing ventilation of the interior of the building in which the roof window is mounted. The roof window comprises a frame () defining a frame plane and including a pane () mounted in said frame. The frame comprises a top frame member () intended for being located highest in the mounted state when seen in the direction of inclination of the roof structure, a bottom frame member opposite the top frame member, and two side frame members extending between the top frame member and the bottom frame member, said frame members together form a window structure delimiting a frame opening and each having an interior side () intended for facing the interior in the mounted state, an exterior side intended for facing the exterior, an inner side () facing the frame opening and an outer side () facing away from the frame opening. The ventilation unit is configured for being arranged primarily adjacent to the outer side of a frame member, and comprises a lower side () configured for being arranged adjacent to or at the interior side () of said frame member (). The roof window system further comprises a ventilation panel () allowing air passage from one side of the ventilation panel to another side of the ventilation panel, thereby defining an intended air flow direction, said ventilation panel being configured for facing the interior of the building and extending away from the interior side of the frame member adjacent to which the ventilation unit is mounted.
