Definitions

  • the present teachings relate to an ancillary member for a fenestration unit and to a fenestration unit incorporating such an ancillary member.
  • fenestration units such as windows, doors, and vents
  • the frames for these types of fenestration unit are often provided by connecting a series of frame members with a joint at each corner of the frame, e.g. connecting four frame members at four corner connectors to create a standard four-sided frame.
  • the frame members may be installed into openings together with ancillary components such as sills under the frame or corner posts between adjacent frames of a bay window.
  • connection points between the frame and the ancillary component in the fenestration units are intended to be covered by a separate sealant (e.g. a layer of silicone mastic) to be provided by the installer during the assembly process.
  • a separate sealant e.g. a layer of silicone mastic
  • This known sealant arrangement is often not provided by inattentive installers, or may provide an insufficient sealant barrier. This may lead to the ingress of water and/or air into, or potentially passing through, the fenestration unit.
  • the current process of assembly the frame and the fenestration unit and then subsequently applying a sealant is time consuming.
  • the quality and effectiveness of the resultant seal may be dependent upon the skill of the installer.
  • US2019093416 discloses a mullion system for a window assembly.
  • EP0722033 discloses a corner post for façade composed of plastic framed elements.
  • DE102006007742 discloses a ground cill door element for sealing two spaces in ground area.
  • US2013/047518A1 discloses a door cill with a cover plate.

  • a first aspect provides an ancillary member for a fenestration unit, the ancillary member comprising: an elongate body extending longitudinally between first and second ends thereof, the elongate body defining a cross-sectional profile comprising a first region intended to be externally facing, in use, a second region intended to be internally facing, in use, and first and second side surfaces extending between the first and second regions, wherein the first side surface comprises a first gasket extending at least partially along the elongate length of the body such that the first side surface is configured for sealingly engaging a first window frame; and wherein the ancillary member is a cill and comprises a cill cover, wherein the first region comprises a first mounting arrangement for releasably mounting an external profile of the cill cover thereon, wherein the first mounting arrangement is configured for mounting the external profile to the body via a snap-fitting arrangement, and wherein the first region of the body comprises a second gasket extending at least partially along the e
  • This arrangement enables an ancillary member to engage a window frame when it is placed within the assembled frame assembly.
  • the member is able to form a seal against said frame without requiring any additional material/processes (e.g. an additional silicone seal), which simplifies the installation of the fenestration unit for an installer.
  • Providing a body that is releasably connectable to an external profile allows the body and profile to be made from different material, e.g. to allow the body to be made from an insulating material to provide a thermal break, whilst allowing the external profile to be made from a metallic material, e.g. aluminium, to improve its appearance and match the surrounding frame components.
  • This arrangement also enables the external profile to be replaced, e.g. during maintenance, and may reduce wastage of materials at the assembly stage. The use of such a mounting arrangement has been found to simplify the installation of the fenestration unit for an operator.
  • this seal on the ancillary member helps to reduce draughts flowing through the assembled fenestration unit and also help to reduce the ingress of water.

  • This arrangement also enables the internal profile to be replaced, e.g. during maintenance.
  • the second mounting arrangement may be configured for mounting the internal profile to the body via a snap-fitting arrangement.
  • the second region may comprise a third gasket extending at least partially along the elongate length of the body such that the second region is configured for sealingly engaging the internal profile.

  • the ancillary member may be positioned between two window frames, and the second region may comprise a third gasket extending at least partially along the elongate length of the body such that the second region is configured for sealingly engaging first and/or second window frames, in use.
  • This arrangement works to improve the seal formed between the ancillary member and a window frame, further inhibiting the ingress of air and/or moisture through the fenestration unit.

  • additional material/processes e.g. an additional silicone seal
  • This seal on the frame member helps to reduce draughts flowing through the fenestration unit and also helps to reduce the ingress of water.

This in turn may enable window and door installers to minimise wastage of external profiles by assembling the desired combination of profile colour and/or shape at or near to the point of installation from a selection of available profiles, by cutting the profiles to the required length and keeping the remainder for future jobs, rather than having to pre-order the a minimum length of complete ancillary member from a supplier, much of which may ultimately go to waste.
