Definitions

  • the present invention relates to an adapter frame for installing a skylight window having a window frame in or on a roof of a building, said adapter frame comprising a plurality of adapter frame side members, the plurality of adapter frame side members delimiting an adapter frame opening and defining an adapter frame plane, the adapter frame plane extending in a longitudinal and a lateral direction, a first of the adapter frame side members extending along a first peripheral side of the adapter frame opening in the longitudinal direction, the first adapter frame side member having a flange section extending in an exterior direction perpendicular to the adapter frame plane, the flange section having an inner flange surface, the inner flange surface extending in the exterior direction, the flange section having an outer flange surface opposite the inner flange surface, the first adapter frame side member having a support section extending from the flange section in an inward direction toward the adapter frame opening and perpendicular to the longitudinal direction, the support section having an exterior support surface facing in the exterior direction,
  • the invention also relates to a system comprising a skylight window, and a method of installing a skylight window through such an adapter frame.
  • Inclined skylight windows are typically built into an opening in an inclined roof structure, the roof having 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.
  • IGU insulating glazing unit
  • the installation of a skylight window generally comprises transporting the skylight window to the roof, positioning the skylight window in or on the roof at a desired position wherein the skylight window covers an opening in the roof and fastening the skylight window to the roof.
  • the installation may further comprise the mounting of a roofing felt for weather-proofing the window.
  • a skylight window may be hard to handle and install, due to being heavy weight and fragile.

  • One non-limiting advantage that is gained by such an adapter frame is facilitating the installation of a skylight window in or on roof.
  • the receiving section is formed.
  • the receiving section may provide a guidance for the positioning of the skylight window on the adapter frame, further facilitating the installation of the skylight window as the inner flange surface may ensure correct placement of the skylight window, reducing installation time and preventing errors in installation.

  • This may have the effect of facilitating the installation of the skylight window, as the skylight window may be positioned directly on the adapter frame guided by the receiving section or receiving sections of the adapter frame, thus reducing the handling of the skylight window, which may be both heavy and fragile making it troublesome to handle.
  • This also provides a skylight window which in the installed position may be structurally supported by the adapter frame.
  • the adapter frame may be installed at a desired position on the roof after which the skylight window may be positioned on the adapter frame such that the receiving section receives a part of the window frame.

  • Less material along the exposed interior major surface and a peripheral side of the IGU may allow the IGU to be positioned deeper or lower in the window structure, as well as closer to the window frame, which may improve the insulating properties of the skylight as the relative area of the IGU may be increased.
  • An increase in relative area of the IGU may further improve light inflow and view through the skylight. This also reduces the area of sash, and so the likelihood of thermal bridges through which heat energy can escape (or enter) from the interior of the building.
  • the first sash side member has a first leg connected to a supporting section of the first sash side member supporting the IGU, the first leg extending in the longitudinal direction and extending substantially in a height direction substantially perpendicularly to at least one of the major surfaces of the IGU, the first leg having a thickness in a width direction extending perpendicularly to said length and height directions.
  • At least a portion of the first leg of the first sash side member is generally plate-shaped, consisting of one single section of substantially solid material having a said thickness less than 1 cm.
  • the first leg having a thickness less than 1 cm may have the advantage of allowing the IGU to extend closer to the frame side members as the thickness of material extending along the peripheral sides of the IGU is reduced.
  • This may have the effect of improving the insulation properties of the skylight as the relative area of the superior insulating IGU is increased compared to other parts of the skylight. Moreover, this will lead to a more light-weight structure that can potentially be easier to manufacture and lead to cost savings with regards to the material use.
  • plate-shaped may be understood as the first sash side member being generally flat.
  • substantially solid material may be understood as no cavities and/or hollow spacings are comprised in the material structure.
  • the portion of said first leg having a thickness less than 1 cm of the first leg may correspond to any estimable part that comprises the first leg.
  • thickness of said first leg refers to the extent that the first leg extends in the direction of the width dimension, being perpendicular to the height and length dimensions, as defined previously.

  • This may have the effect of facilitating the installation of the skylight window, as the skylight window may be positioned directly on the adapter frame guided by the receiving section or receiving sections of the adapter frame, thus reducing the handling of the skylight window, which may be both heavy and fragile making it troublesome to handle.
  • This also provides a skylight window which in the installed position may be structurally supported by the adapter frame.
