Definitions

  • the present invention relates to improvements in metal frame elements for framing openings, for example for windows or doors, which incorporate thermal barriers to prevent conduction of heat from one side of the frame to the other.
  • Such elements generally comprise a frame member, e.g. extruded of aluminium,with the or each wall connecting the two sides of the frame element provided with a break which is bridged with a suitable thermally insulating plastics material to create the thermal barrier.
  • the wall is generally provided with a channel open along one face. The channel is filled with the thermally insulating plastics material in liquid form, and after the plastics material has set, a part of the wall of the channel is removed to create the break. For this, access is required both to the open face of the channel and to another face, to fill the channel and then to remove a part of the wall of the channel respectively.
  • a thermal barrier is required to be provided in both walls 6 and 7 and, to this end, a channel 9 is provided having an opening 10 in wall 6 and channel 11 is provided having an opening 12 in wall 7 and an aligned opening 13 for providing access to the opposed face of channel 9.
  • the frame element of Figure 1 is inverted and channel 9 is filled with a suitable thermally insulating plastics material 14, as shown in Figure 2, through opening 10.
  • a suitable thermally insulating plastics material 14 is set, a part of the wall of channel 9 is removed to create break 15, as shown in Figure 3, access being obtained through the openings 12,13 of channel 11.
  • the member is then inverted and the opening 13 in channel 11 is closed using for example a strip 16 of thermally insulating material, as shown in Figure 4, or a plug 17 of thermally insulating material as shown in Figure 5.
  • channel 11 is filled with a suitable thermally insulating material 18 as shown in Figure 6. It will be appreciated that this method of producing the thermal breaks in both walls 6 and 7 is not only expensive because it is time consuming but it is also difficult to achieve a finished product having good dimensional stability because the member 1 has an open hollow section, the two sides of the member 1 being only connected by the part of the wall of channel 9 which is subsequently removed to create break 15.
  • an elongate frame element comprising providing an elongate metal frame member having a closed hollow interior in part bounded by walls interconnecting the sides of the member,providing thermally insulating plastics material in the hollow interior arranged so as to interconnect the sides of the member and removing portions of the interconnecting walls along the length of the member so as to provide discontinuities therein forming thermal breaks.
  • the member may be provided with channels in each of the said walls, each channel having a single opening in the respective said wall and wherein after the interior space of the member has been filled with thermally insulating plastics material, a part of the wall of each channel is removed to create the break or discontinuity and the channels are then filled with thermally insulating plastics material.
  • the plastics material used to fill the interior of the section has a lesser strength than the plastics material used to fill the channels.
  • the completed frame element shown in Figure 7 comprises an extruded aluminium member 21 having a hollow interior 22 defined by side walls 23, 24 and walls 25, 26 perpendicular to and interconnecting the side walls. Side walls 23, 24 are extended by flanges 27, 28 for mounting purposes.
  • the walls 25, 26 each have longitudinal breaks 29, 30 providing thermal barriers and the hollow interior 22 is filled with a thermally insulating plastics material 31, for example a rigid closed cell plastics foam, such as polyurethane, which has a relatively low structural strength, and, in the area of the breaks 29, 30, the portions of walls 25, 26 are interconnected by thermally insulating plastics material 32, 33 which has a high structural strength, for example non-foamed polyurethane.
  • the above described frame element is made starting from an elongate extruded aluminium member 21, as shown in Figure 8, which has a closed hollow interior 22a defined by the walls 23 to 26 and channels 34, 35 which are provided in walls 25, 26 within the confines of the rectangle defined by walls 23 to 26.
  • the channels 34, 35 each have a single opening 36, 37 in the respective walls 25, 26 and the walls of the channels interconnect the portions of the walls 25, 26 to either side of the openings 29, 30 and thereby close the interior of the member.
  • members 21 of a suitable length for example 5 metres are used.
  • One end of the interior 22a of the member 21 is plugged, the plug being provided as required with air vents, and the whole of the space in the interior 22a is filled, as shown in Figure 9, with the thermally insulating foam plastics material 31.
  • This may be effected using a lance which is fully inserted into the interior of the member and progressively withdrawn, or by providing a nozzle at the open end of the interior and which projects the foam plastics material at high speed from that end to the other closed end.
  • portions 38a, 39a of the walls of the channels opposite the openings 36, 37 are removed, as shown in Figure 10.
  • the portions 38a, 39a of the walls of the channels can simply be removed using, for example, a circular saw which passes through the openings 36, 37 respectively. Thereafter first one channel and then the other is filled with a structurally strong thermally insulating plastics material 32, 33, as shown in Figure 7. This can be effected for example by providing the element on a conveyor which is moved progressively past a nozzle or pouring head for the liquid plastics material, the two ends of each channel being closed by an appropriate plug. The frame element is then complete.
  • the aluminium member is extruded with a closed hollow interior so that it can be made with a high degree of accuracy and the walls of the member are not broken until the interior space is filled with the plastics material 31 which is selected to have sufficient rigidity to hold the two parts together in their correct orientation while the channels 34, 35 are being filled.
  • the arrangement of the channels 34, 35 extending into the rectangle bounded by walls 23 to 26 gives the foam material 31 a generally-H-shape so that it is keyed in the member.
  • the channels 34, 35 are provided with inwardly projecting walls to key the plastics material 32, 33.
  • FIG. 11 Another embodiment of frame element is shown in Figure 11.
  • the channels 34, 35 are arranged in adjacent corners of the rectangle defined by walls 23 to 26.
  • the channels 34, 35 are filled with thermally insulating plastics material 32, 33 which structurally interconnects the two sides of the element and a space within the interior of the element is provided with thermally insulating plastics material 31.
  • a steel rod (not shown), forming part of a locking mechanism, extends in use from end to end of the element.
  • an elongate thermally insulating plastics housing 40 is provided in the interior of the frame element in which the steel rod is received.
  • the plastics housing 40 is positively located in the element by lugs 41.
  • the plastics material 31 must be compatable with the plastics material 32, 33 because the two are in contact and that the same plastics material could be used to fill the interior 22 as is used to fill the channels 34, 35.
  • a structurally strong plastics material is required for filling the channels 34, 35 this will create a more expensive element. If the structurally strong plastics material is used to fill the interior of the hollow section, while inwardly projecting walls may still be provided for keying the plastics material in the member, the channels 34, 35 may be omitted, the member 21 being formed with continuous walls 25, 26, portions of which are then cut away to provide the thermal breaks when the interior has been filled with the plastics material.
  • plastics materials for filling the hollow interior of the element and for bridging the walls of the element at the breaks. It will be appreciated that other materials may be used.
  • the basic requirements for the plastics materials are that, for filling the hollow interior of the element, the material should provide a degree of thermal insulation which is preferably better than that of the air which it displaces and should have sufficient strength merely to hold the two parts of the element together in their correct relative orientation after the breaks 38, 39 have been made, while channels 34, 35 are being filled and while the filling sets.
  • the material filling the hollow interior of the element is mechanically keyed by the channels in the embodiment of Figure 7 or to a lesser extent in the embodiment of Figure 11 by lugs.
  • a mechanical key may not be necessary where the material adheres sufficiently to the walls of the element.
  • its thermal transmission rate must be substantially lower than that of the material of which the element is made, for example aluminium, and it must have sufficient structural strength to fulfil the requirements of a particular design and for the full range of temperatures for which the design is intended.
