Definitions

  • This invention relates generally to a window and more particularly to windows for use in buildings and fixed structures.
  • windows comprise a frame and a sash.
  • the frame which is permanently attached to the building or other structure, provides the aperture in which the sash is fixedly or movably located.
  • the sash holds the glazing.
  • window frames and sashes have been formed of wood (timber) or metal (iron, steel, aluminium). It is also known to use other materials such as plastics.
  • plastics have become the material of choice because they can be mass fabricated and are cheap.
  • PVC is extruded into hollow lengths or sections which are secured together to provide both the frame and the sash. Because of the nature of PVC, the sections are typically large and internal reinforcement (for example metal sections) may be used to impart upon a PVC section (and hence the so-formed window) the necessary rigidity. Because the sections are large, the visible area of the window is reduced and the area available for glazing is less than is often offered by traditional systems.
  • a first aspect of the invention provides a window having a frame and a sash for receiving glazing, the frame comprising a first frame element permanently joined to a second frame element, the sash having a first sash element for receiving a glazing unit and a second sash element for securing the glazing unit to the first sash element, the sash being movably attached to the frame and having a first lock element wherein, in use, and with the sash closed with respect to the frame the first lock element engages a second lock element which extends through both the first frame part and the second frame part.
  • the first lock element is a lock keep and second lock element is the lock body or mechanism.
  • Having the lock body in the frame is beneficial because it allows the sash components to be smaller than would otherwise be required and also allows a larger and/or more robust and/or more complex lock to be used. Locating the lock body in the frame may increase security.
  • the first frame element and the second frame element may be formed from the same or different materials.
  • the first frame element may be visible from and face a first side of the window and the second frame element may be visible from and face a second side of the window.
  • a second aspect of the invention provides a window having a frame and a sash for receiving glazing, the frame comprising a first frame element permanently joined to a second frame element, the sash having a first sash element for receiving a glazing unit and a second sash element for securing the glazing unit to the first sash element, the first frame element and the second frame element being formed from different materials, the first frame element being visible from and facing a first side of the window and the second frame element being visible from and facing a second side of the window.
  • the sash may be movably secured to the frame.
  • the sash may carry a first lock element wherein, in use, and with the sash closed with respect to the frame the first lock element engages a second lock element which extends through the frame, and preferably through both the first frame element and the second frame element.
  • first and second frame element rather than a single unitary body, the choice of materials available to the fabricator and/or designer is wide. This means that aesthetics, cost and, for example, physical and/or thermal performance can be optimised according to location, climate, need and desire.
  • the first frame element may be formed from wood or timber.
  • the second frame element may be formed from plastics material, for example a thermoset polymer.
  • the second frame element may comprise fibre reinforced polymer (FRP).
  • FRP fibre reinforced polymer
  • the second frame element may be a pultruded part. If the second side of the window is or corresponds to the outside of a structure or building the use of polymers, for example, thermoset polymers, and in particular FRP, e.g . pultruded sections, is beneficial because of the excellent environmental stability and, in the case of thermoset polymers, a low coefficient of thermal expansion.
  • the use of timber may be beneficial because of the physical properties and/or aesthetic qualities of timber and/or because of the different cost bases of timber products, for example variety of different types of timber (e.g . formed from hardwood or softwood).
  • the timber may be a pressure treated and/or laminated timber structure. If laminated, the timber may be laminated with a fascia material, for example to provide a preferred visual look.
  • timber may be beneficial because it allows for robust lock components to be securely housed within the frame. It may be further beneficial because the lock does not intrude beyond the sight line, i.e. above the frame.
  • the first and second frame elements are preferably joined so as to define an aperture-facing or abutting surface, the aperture abutting surface being planar.
  • the aperture abutting surface is preferably defined by the first frame element and the second frame element together.
  • Both the first frame element and the second frame element may be formed as solid components, rather than as hollow sections. This helps with rigidity and/or in providing a low sightline.
  • the first frame element and the second frame element may house lock components for securing the sash to the frame in use.
  • the window comprises a slam lock or automatic dead latch, that being a lock which automatically locks when the sash is brought into closing relations with the frame.
  • the first sash element preferably carries a handle for manipulating the sash.
  • a further aspect of the invention provides a window having a frame and a sash, the frame being formed from a first and second frame element, both being formed of different materials, the sash being hingedly connected to the frame, the window having an exterior sight line of less than 60 mm and a U value of less than 1.15 Wm -2 K -1 .
  • the window may have an exterior sight line of less than 60 mm and/or a U value of from 0.5 to 1.15 Wm -2 K -1 , for example of from 0.5 to 0.8 Wm -2 K -1 or from 1.0 to 1.15 Wm -2 K -1 , the former range preferably being in relation to a triple-glazed window and the latter range preferably being in relation to a double glazed window.
  • a window 1 having a frame 2, which is to be (or is) mounted in an aperture of a building or structure (not shown).
  • the frame holds a sash 3 which retains glazing 4.
  • the window 1 comprises two opening sashes 3o and one fixed sash 3f.
  • Other configurations of window 1 are possible, for example a single window 1 having an opening or closed sash, double window and so on.
  • Each opening sash 3o is top hung so as to pivotally open by rotation about a hinge and is connected to the frame 4 via a side mounted friction hinge FH to allow the sash 3o to pivot and slide away from the top edge 2t of the frame 2.
  • Other hinge arrangements may also be deployed, for example the sash 3o may be bottom hung or side hung or the window 1 may be partly or fully reversible to facilitate cleaning of windows 1 located at height.
  • Figure 2 provides a sectional view through a window 1 of Figure 1 at the bottom edge 2b of the frame 2 of the window 1 for one of the opening sashes 3o.
  • Each of the frame 2, sash 3 and glazing 4 of the window 1 is shown.
  • the glazing 4 is a double-glazing sealed unit.
  • the sash 3 carries a handle 5.
  • the sash 3 and frame 2 each carry elements of a lock 6 and the frame 2 carries a lock release lever 7.
  • the lock release lever may be incorporated in the handle 5, or may be absent or provided elsewhere.
  • the frame 2 comprises a first frame element 2a and a second frame element 2b secured together.
  • the two frame elements 2a, 2b together provide a wall surface 2c defining a plane PL.
  • the first frame element 2a is a solid elongate body, usually formed of wood.
  • the first frame element 2a has an interior facing surface 20 and an opposite surface 21. Extending between the room facing surface 20 and the exterior facing surface 21 is a wall facing surface 22, forming part of the wall surface 2c and an opposite surface 23.
  • the exterior facing surface 21 comprises a first lip portion 21a and a second lip portion 21 b each extending away from the interior facing surface 20 and defining therebetween a rebate 23.
  • the first lip portion 21 a extends beyond the second lip portion 21 b.
  • Extending into the first frame element 2a on at least one of the sides of the window 1 (and typically the bottom edge 2ii) from the exterior facing surface 21 is a rebate 24 (see Figure 2 ).
  • the rebate 24 communicates, on said at least one side of the window 1, with a blind aperture 25 extending into the body from the opposite surface 23.
  • the second frame element 2b which is preferably formed as a pultruded length of FRP, is shown in Figure 2B and is a substantially "J" shaped member having a leg part 201 and a foot part 202 extending from the leg part 201.
  • the leg part 201 has a wall facing surface 203 which forms a part of the wall surface 2c.
  • the obverse face 204 of the leg part 201 has plural elongate rebates 205 for accepting weather seals WS 1 , WS 2 .
  • the leg part 201 Towards a distal end 201 d of the leg part 201, the leg part 201 thins to define an elongate slot 206, for receiving, where appropriate or desired, a part of a hinge H, for example friction hinge FH, to facilitate the opening and closing of the window 1.
  • the foot part 202 comprises an interior facing surface 207 and an exterior facing surface 208. Extending away from the interior facing surface 207 is a return 209 which, together with the obverse face 204 of the leg part 201 defines an elongate rebate 211. Each of the return 209 and obverse face 204 carry facing abutment lips AL. An elongate cut-out 210 is provided at the connecting corner of the leg part 201 and foot part 202.
  • the interior facing surface 207 of the foot part 202 abuts the opposite surface 23 of the first frame element 2a such that the second lip portion 21 b extends into the cut-out 210 and the first lip portion 21 aligns with the return 209, the lip portions 21 a, 21 b of the first frame element 2a thereby embracing the foot portion 202 of the second frame element 2b.
  • the two frame elements 2a, 2b may be joined together by way of adhesives, screws, and/or other fasteners.
  • the first lip portion 21 a obscures the view of the return 209 of the second frame element 2b.
  • FIG. 2C there is shown a sash 3' configured to receive a triple glazing unit (not shown).
  • the difference between the sash 3 of Figure 2 and the sash 3' of Figure 3 is the second sash element 3b and 3b', advantageously the first sash element 3a being identical in both cases.
  • the first sash element 3a which may be formed from pultruded FRP, has an elongate limb 31 extending in a plane parallel to the wall surface 2c and having a wall surface facing side 31w and an obverse, glazing facing side 31g.
  • the elongate limb 31 further comprises, at a distal end 31 d, a pair of orthogonal webs, 32a, 32b extending in opposite directions and providing an exterior surface 33.
  • the glazing facing surface 31g being disposed between a channel 31c proximate one of the webs 32a and an abutment face 31f.
  • the abutment face 31f will typically support a packer element.
  • Each of the orthogonal webs 32a, 32b has, on a face obverse 34 to the exterior surface 33, an elongate slot 35 for carrying in each a weather seal WS 3 , WS 4 (see Figure 2 ).
  • the proximal end 31 p of the elongate limb 31 has a pair of rebates 36 for receiving feet 303 of the second sash element 3b' (or indeed second sash element 3b as seen in Figure 2 ).
  • the proximal end 31 p of the second sash element 3a also comprises an elongate cut-out 37. Between the distal and proximal ends 31 d, 31 p there is provided a slot 38 extending into the elongate limb 31 from the wall facing side 31w.
  • the second sash element 3b' which may be formed from plastics material (e.g. PVC), wood of similar design or aluminium, preferably PVC, comprises a pair of facing legs 301', interconnected by a roof portion 302'.
  • the second sash element 3b' may be formed from pultruded FRP although we have surprisingly found that pultruded FRP may make the section too stiff for some embodiments, for example embodiments where the window 1 is less than 600mm long.
  • Each of the legs 301' terminate in a foot 303' for receipt in the rebates 36 of the first sash element 3a.
  • the feet 303' snap fit in the rebates 36.
  • An interior facing surface of the second sash element 3b' may comprise a decorative return 307'.
  • the exterior facing surface of the second sash element 3b' may carry a rebate 303' for receipt of a weather seal WS 5 (see Figure 2 ).
  • the second sash element 3b' is configured to allow receipt of a triple glazing unit in a window 1' of the invention.
  • an extension 301e (as shown in Figure 2 ) it is a trivial matter to configure the window 1 for receipt of a double glazing unit.
  • this realises the opportunity for glazing upgrades or changes as may be required, and also ensures that the minimum of components need be changed when making such an alteration.
  • first frame element 2a and second frame element 2b are secured together and joined to form a peripheral frame 2 for receipt in an aperture, for example in a wall.
  • the lengths are mitred or part-mitred (or alternatively not mitred) and joined together by adhesives and/or physical fixings.
  • the so-formed frame 2 is configured for the first frame element 2a to provide the room facing portion of the frame 2 and for the second frame element 2b to provide the exterior-facing portion of the frame 2.
  • the interior facing surface 207 of the foot part 202 of the second frame element 2b abuts the opposite surface 23 of the first frame element 2a such that the second lip portion 21 b extends into the cut-out 210 and the first lip portion 21 aligns with the return 209, the lip portions 21 a, 21 b of the first frame element 2a thereby embracing the foot portion 202 of the second frame element 2b.
  • the two frame elements 2a, 2b may be joined together by way of adhesives, screws, and/or other fasteners.

  • the lock release lever 7 may be of a different form or may be located elsewhere, such as within or on the handle 5.
  • the frame 2 By fabricating the frame 2 in two parts it is possible to provide different internal and external finishes, thereby enabling the internal and external characteristics of the window to be matched to likely environmental conditions. Moreover, the use of FRP and timber allows the window components to be strong, thereby reducing the physical bulk of the frame 2 and sash 3 components. Indeed, we have found that the exterior sight line ESL of the window 1, as seen in Figure 3 may be less than 60 mm and can be less than 55 mm, that the interior sight line ISL may be less than 50 mm and can be less than 45 mm and the depth D of the window 1 can be less than 140 mm and may be less than 135 mm for a triple glazed window. A low sight line is beneficial because it allows more natural light into a room. This can have positive environmental effects in, say, cloudy or dim conditions because the use of artificial lighting may be reduced. A low sight line is also of benefit environmentally because a larger glass area improves the U value of the window 1.
  • the window 1 is strong it facilitates security and allows robust locking components to be deployed.
  • the lock body or mechanism 6 By locating the lock body or mechanism 6 in the frame 2, and specifically extending through the first frame element 2a and second frame element 2b, and by sizing the frame 2 appropriately, larger and more robust locks can be deployed than would otherwise be available, Because the lock mechanism is located or locatable in the frame 2 the sash 3 can be made smaller.
  • the internal beading of the window 1 means that glazing 4 can be replaced or upgraded easily and from the inside of a building. This increases security and/or is of particular importance when the windows 1 are installed at elevated positions, for example in tower blocks or other multi-storey buildings because it obviates the need for lifting apparatus to access the window 1.
  • the use of pultruded FRP on the exterior facing surfaces of the window 1 ensures a durability, excellent thermal performance and a long lifetime. Moreover, it can also be fabricated to provide Class 0 or Class 1 fire resistance (for example by choosing appropriate resin systems).
  • the use of pultruded sections is also beneficial because thin walled pultrusion can be used to generate fine features, such as the weather seal rebates.
  • the provision of five weather seals WS 1-5 ensures that the window 1 has excellent thermal performance.
  • Our tests show that the U value of the windows 1 of the invention is as follows: Window Type U Value / Wm -L K -1 Centre Pane Value Window of Invention Double Glazed 1.0 1.0 - 1.15 (e.g. 1.08) Triple Glazed 0.5 0.5 - 0.8 (e.g. 0.65)
  • windows of the invention can be fabricated as openable windows (e.g. Figure 2 ) and closed.
