Definitions

  • the present invention relates to a skylight window frame for being installed in or on a roof of a building, comprising four frame side members, the frame side members delimiting a frame opening and defining a frame plane extending in a longitudinal direction and a lateral direction, a first of the frame side members extending along a first peripheral side of the frame opening in the longitudinal direction, a second of the frame side members extending along a second peripheral side of the frame opening in a lateral direction, each frame side member having a frame height extending in a height direction, the height direction being perpendicular to the frame plane, the first frame side member comprising a first leg, the first leg extending substantially in the height direction, and a second leg, extending substantially in the lateral direction, wherein the first leg has an outer side, the outer side facing away from the frame opening, wherein the second leg has an interior side configured to face an interior of the building in an installed position of the skylight window frame, the outer side having a major outer surface and optionally a curb flange located at a
  • the invention also relates to a system comprising a skylight window and a method of fastening a window frame onto a roof structure.
  • Inclined skylight windows are typically built into an opening in an inclined roof structure, the roof having with an angle above 15 degrees, with a substantial part of the inclined skylight window being positioned within the inclined roof structure in an installed position.
  • Flat-roof skylight windows are generally installed on top of the exterior side of flat roofs of buildings, where the inclination of the roof is less than 5 degrees with respect to a horizontal plane of the roof.
  • flat-roof skylight windows are installed to cover an opening in the roof, i.e. a substantial part of the flat-roof skylight window extends above an exterior side of the flat roof structure in an installed position.
  • Skylight windows of these types often comprise a window frame, an insulating glazing unit (IGU), a weather shield, and potentially a window sash, if the skylight window is openable.
  • the window frame may be denoted a skylight window frame.
  • the window frame may comprise curb flanges, such curb flanges being positioned at an outer side of the window frame at a lower portion of the window frame, the lower portion being the adjacent to the exterior roof side in an installed position of the window frame.
  • the curb flanges generally extend along the frame side members.
  • the curb flanges may have inclined surfaces, whereby the curb flanges may serve as roofing felt mounting surfaces, preventing a roofing felt from being mounted with a 90 degree bend, the roofing felt possibly acting as a flashing.
  • curb flanges are sometimes used for fastening the skylight window to the roof, by mounting fasteners through the inclined surface of the curb flange.
  • skylight windows may be fastened to the roof by brackets, such as angle brackets, mounted to the window frame and roof.
  • an object of the present invention is to provide a skylight window frame, facilitating proper and secure attachment of a skylight window to a roof of a building.
  • an object of the invention is to provide a skylight window frame that can potentially be used in both skylight windows which require a curb and skylight windows which do not require a curb flange.
  • a skylight window frame according to the introduction, which is furthermore characterized in that the pre-formed hole extends from the major outer surface of the first leg of the first frame side member towards the interior side of the second leg in a direction which is inclined in relation to the frame plane.
  • One non-limiting advantage that is gained by such a pre-formed hole is the facilitation of secure and proper attachment of the skylight window frame and therefore, of the window to the roof.
  • a pre-formed hole By the provision of a pre-formed hole, an installer is provided with a guide for inserting a fastener, the fastener attaching the window frame to the roof, ensuring correct positioning of the fastener and facilitating the installation of the skylight window.
  • the pre-formed hole extending from the major outer surface of the first leg toward the interior side of the of second leg may have the effect of the fastener, which is to be mounted in the pre-formed hole, extending through the main structure of the first frame side member, the main structure being the first and second leg, thus securely fastening the window frame and skylight window to the roof and/or load-bearing structure of the roof.
  • the inclination of the pre-formed hole in relation to the frame plane may have the effect of the pre-formed hole being easily accessible to the installer of the skylight window.
  • the inclination may further allow the window frame to be fastened to a structure located beneath the window frame, such structures could be a load-bearing structure of the roof, such as a rafter.
  • the inclination further necessitates the use of long fasteners, which may offer a secure and stable attachment to the roof.
  • the inclination of the pre-formed hole may in the installed skylight window provide good resistance toward vertical forces, such as wind suction, reducing the risk of the skylight window frame being pulled off of the roof.
  • the inclination of the pre-formed hole may hinder water from entering the pre-formed hole in which the fastener is mounted in an installed position of the window frame.
  • a skylight window comprising a window frame according to the invention may further allow for flexibility in any assembly of the skylight window prior to installation.
  • a further advantage of the invention may be that the same window frame may be used for a skylight window for an installation requiring a curb flange as well as for an installation which does not require a curb flange.
  • the pre-formed hole of the skylight window frame allows the skylight window frame to be securely fastened to the roof even without a curb flange.
  • the integrated pre-formed hole may also reduce the overall footprint of the skylight window, as the window frame does not need protruding flange elements or brackets for fastening. This may allow for multiple skylight window units to be placed next to each other in proximity on the same roof structure.
  • the term "interior” is used to indicate that something is intended to face the interior of the building in or on which the window frame is installed, in an installed position of the window frame.
