Roof window frame comprising reinforcement profile with temperature management functionality

A roof window, wherein the roof window comprises a frame supporting a glass unit comprising an first outer major surface for facing the interior of a building, and a second outer major surface for facing away from the interior of a building when the window is installed in an aperture of a building,

• wherein the frame comprises a plurality of frame profiles having a longitudinal direction arranged to extend parallel to a side surface of the glass unit, and where the frame profiles together defines a frame opening, wherein one or more of said frame profiles are hollow and comprises an interior frame profile space enclosed by exterior frame profile walls defining the exterior surface of the corresponding frame profile,
• wherein a frame reinforcement profile is arranged in the interior frame profile space, and wherein the thermal conductivity coefficient of the material of the reinforcement profile is higher than the thermal conductivity coefficient of the material of the exterior frame walls, wherein the frame reinforcement profile has a reinforcement profile length extending substantially parallel to the longitudinal direction of the frame profile,
• wherein the reinforcement profile comprises a wall part extending in a direction away from a first region located proximate a first plane comprising the first outer major surface of the glass unit, and moreover extends in the interior frame profile space in a direction away from a second plane, so that the interior space is split into a first space part located at a first side of the reinforcement profile, and a second space part located at a second side of the reinforcement profile,
• where the second plane is perpendicular to the first plane, extends parallel to the longitudinal direction of the frame profile comprising said reinforcement profile in the interior frame profile space, and touches a part of an exterior surface of a first exterior wall of the frame profile that faces and is proximate the frame opening below the first outer major surface,
• wherein said wall part extends between
• (i) the first exterior frame profile wall or the exterior frame profile wall that faces an overlapping part of the glass unit and the first outer major surface, and
• (ii) another exterior frame profile wall comprising an exterior surface facing away from the frame opening or another exterior frame profile wall configured to face the interior of the building,
• so that a controlled thermal bridge is formed between said exterior frame profile walls.
