  • the at least one aperture comprises one or more apertures adapted to receive a pattress box, for example a pattress box made to comply with BS4662:2006.
  • the pattress box may be single or double gang. It may be of the type for use with plasterboard, having retaining lugs to secure the box to the plasterboard (although, in this case, the lugs will secure the box to the front wall of the stud).
  • the at least one aperture may comprise one or more apertures aligned with a respective pattress box integral with the front wall of the stud and disposed in the channel.
  • an opening in an integral pattress box is aligned with an aperture to allow an electrical fitting to be inserted through the aperture into the pattress box.
  • the integral pattress box will normally be provided with threaded inserts to enable an electrical fitting to be secured to it with screws.
  • the integral pattress box may be made to comply with BS4662:2006.
  • the pattress box may be single or double gang.
  • the at least one aperture may comprise a first aperture proximal a first end of the stud.
  • the at least one aperture may also comprise a second aperture proximal a second end of the stud.
  • the at least one aperture comprises a first notch formed in a first end of the stud. In this embodiment, the at least one aperture preferably comprises a second notch formed in a second end of the stud.

  • the first one of the first and/or second series of apertures may be a notch in the first and/or second end of the stud.
  • apertures or notches at the ends of the stud allows cables and flexible pipes (e.g. push-fit plastic plumbing pipes) to be inserted into the channel at each end after the stud has been affixed to the substrate. It is also straightforward, using such apertures and notches, to reach and pull through cables offered into the channel from underneath a suspended floor below or a ceiling void above.
  • cables and flexible pipes e.g. push-fit plastic plumbing pipes
  • the or each series of apertures will comprise 50mm apertures (for example, a series of four apertures) spaced apart by, for example, 30mm.
  • the stud comprises a layer of insulation disposed in the channel, the thickness of the insulation being less than the distance by which the front wall is spaced apart from the substrate.
  • this layer of insulation is disposed in the channel such that it is adjacent the front wall. The layer of insulation in the channel prevents the stud acting as a cold bridge, which would otherwise limit the performance of the installed insulation.
  • a particulate insulation material can be provided between the layer of insulation disposed in the channel and the substrate.
  • the layer of insulation can be provided with at least one cut-out corresponding with the at least one aperture.
  • the layer of insulation can be provided with at least one cut-out corresponding with the at least one aperture.
  • the stud may further comprise at least one retaining flange to retain the layer of insulation in the channel.

  • the side walls normally join the front wall at the corners of the stud. Together, the side walls define another two sides of the channel.
  • the back side of the channel i.e. the side opposite the front wall is nornnally left open against the substrate.
  • the retaining flanges are nornnally fornned in the pair of opposed, spaced apart side walls.
  • At least one of the pair of side walls may be provided with a first side wall aperture proximal a first end of the stud, the first side wall aperture allowing access to the channel.
  • at least one of the pair of side walls is normally provided with a second side wall aperture proximal a second end of the stud, the second side wall aperture allowing access to the channel.
  • At least one of the pair of side walls may be provided with a first side wall notch formed in a first end of the stud, the first side wall notch allowing access to the channel.
  • at least one of the pair of side walls may be provided with a second side wall notch formed in a second end of the stud, the second side wall notch allowing access to the channel.
  • the side wall apertures or notches may be provided in both side walls at both ends. Thus, a total of four apertures or notches (two in each side wall) may be provided.

  • the fixings may be one or more of screws, nails or glue.
  • a kit of parts comprising a plurality of studs according to the first aspect of the invention and fixings to secure each of the plurality of studs to a substrate.
  • the fixings are insulated fixings. This ensures that the fixings are thermally insulated from the substrate to prevent cold bridging.
  • the kit of parts may further comprise sole and/or head members for affixing to a floor and/or ceiling respectively and adapted to receive the ends of the plurality of studs. This enables a free-standing structure to be erected if required and also allows the studs to be used to fit insulation against an uneven substrate.
  • the kit of parts may further comprise a removable skirting moulding and/or a removable crown moulding for attachment to the plurality of studs.
  • the skirting moulding and/or crown moulding may also or instead attach to the sole and/or head members, if used.
  • the skirting moulding and crown moulding cover the apertures or notches in the front wall at the ends of the stud, but since they are removable allow easy access to the channel through the apertures or notches in the future.

  • Figure 2 shows a front elevation of a stud according to the invention
  • Figure 3 shows a side elevation of a stud according to the invention
  • Figure 4 shows a cross-section through a second example of a stud according to the invention.
  • Figure 5 shows a cross-section through a third example of a stud according to the invention.
  • Figure 1 shows a stud 1 fitted to a wall 2.
  • the stud comprises a front wall 3 and two side walls 4a, 4b.
  • This stud 1 is affixed to the wall 2 by way of insulated fixings 5a, 5b, which pass through holes in flanges 6a, 6b at the ends of side walls 4a, 4b.
  • the layer of insulation 7 runs the whole length of the stud 1 . It is held in place in the channel by retaining flanges 8a, 8b. These are formed in side walls 4a, 4b and the layer of sheet insulation 7 can be inserted into the channel from one end of the stud between the front wall 3 and the flanges 8a, 8b, which then hold the layer of insulation 7 in position in the channel adjacent the front wall 3.
  • the stud is typically 80mm wide and typically has a depth of 44mm.
  • the surface of the material from which it is made could be coated to reduce cold bridging and/or structural deterioration.
  • a ceramic coating can be used.
  • the thickness of the material from which it is made is typically between 1 mm and 2mm. These dimensions provide room to accommodate 40mm thick sheets of insulation adjacent the side walls 4a, 4b.
  • Another variant of the stud may be deeper, for example 54mm, to provide room to accommodate 50mm thick sheets of insulation, as may be required by modern building regulations.
  • the retaining flanges 8a, 8b are typically about 5mm in length and spaced along the side wall so that the layer of insulation 7 may be 25mm thick.
  • FIGS. 2 and 3 show views of the front and side elevations of the stud 1 .
  • the front wall 3 there are provided two cut-outs 13, 14 for receiving pattress boxes.
  • the pattress boxes are pushed through the cut-outs 13, 14 in the front wall 3.
  • Electrical cables may then be passed into the pattress boxes from the void 12 and electrical fittings (e.g. sockets or switches) coupled to the cables and screwed to the pattress boxes.
  • the pattress boxes will be of the type for use with plasterboard that have fixing lugs that clamp to the plasterboard; these lugs may instead be used to clamp to the front wall 3 and layer of insulation 7.
  • the layer of insulation 7 may either be provided with ready-made apertures aligned with the cut-outs 13, 14 or it may be cut away during installation. Alternatively, as mentioned above, the layer of insulation 7 may be provided with portions aligned with the cut-outs that have a weakened perimeter to enable it to be easily pushed out if access to the cut-out is required during installation.
  • the pattress boxes are fitted as required during installation.
  • the pattress boxes may be integral with the front wall 3 of the stud 1 .
  • the cut-out 13 is typically provided at a suitable height for a light switch, whereas the cut-out 14 is typically provided at a suitable height for a socket outlet. These heights may be dictated by local regulation, such as Part M of the Building Regulations or BS 7671 in the UK.
  • notches 15, 16 in the front wall 3 and notches 17, 18 in the side wall 4a are also provided at the ends of the stud. These notches also allow access to the void 12. They are sized to allow a person to reach through into the void 12.
  • the notches 15, 16 provide a convenient location where an installer can pass cables and/or flexible pipes into the void 12 or pull cables through into the void 12 from a ceiling cavity above or from underneath a suspended floor below.
  • the notches 17, 18 allow cables and/or flexible pipes to be passed out of the side wall 4a and along to an adjacent stud, where they can enter the void of the adjacent stud through similar notches in the side wall. In this way, electrical and plumbing services can be easily fitted after installation of the insulation.
  • the stud 1 In the case where the stud 1 is too tall for a room in which it is to be installed then it can be cut down to size.
  • An additional series of apertures 15a-15c is provided to take the place of notch 15 when the stud is cut down in size. When cut down, one of the apertures 15a-15c will generally be cut through to provide a notch at the top of the stud 1 or will lie close to the top of the stud 1 .
  • the stud 1 will be provided as part of a kit of parts comprising a plurality of studs along with suitable insulated fixings 5a, 5b. Also provided in the kit could be a sole and/or head plate to which the studs can be fastened instead of wall 2 to allow for installation against uneven walls or for a freestanding installation.
  • the kit may also comprise the sheets of insulation 9, 10 and pattress boxes.
  • skirting moulding and crown moulding may also comprise a skirting moulding and crown moulding. These can be affixed to the bottom and top respectively of the studs to conceal the notches 15 (or apertures 15a-15c as appropriate) and 16. They may be removable, for example by making use of clip fittings so that access to the notches 15 (or apertures 15a-15c as appropriate) and 16 can easily be gained in the future if repairs or modifications to the electrical and/or plumbing services are required. Thus, the services can be easily located again in the future with minimum disruption and with no damage to the insulation. If the sole and/or head plate are used then the skirting and crown moulding may also be fixed to these (again, typically in a removable manner).
  • the design of the notches or openings along the front face can ensure that the stud can be cut to any exact room height whilst ensuring an access slot is available at ceiling level.
  • the ceiling level access slots may extend in series from the top end of the stud down to a minimum ceiling height.
  • the stud material can be insulated from the wall to which it is fixed, for example by insulation between the flanges 6a, 6b and the wall. These can for example comprise adhesive strips, such as neoprene strips, and these prevent cold bridging to the stud.
  • the example shown is based on vertical studs. However, additional horizontal studs can be mounted between a pair of vertical studs. These can be used for example to provide a horizontal run of sockets, such as over a worktop. In this way, an insulated electrical conduit is provided.
  • a void 12 is present at the back of the layer 7 of insulation, for the passage of cables.
  • This void enables cables and pipework to be feed along the stud.
  • This void can also be insulated, using particulate insulation material such as polystyrene beads. This provides additional insulation but still allows cables or pipes to be fed along the studs.
  • the insulation contained within the body of the stud can be simply fixed in place using adhesive or by using various mechanical fixings.
  • Figure 1 has parallel side walls 4a,4b, which butt against the sides of the insulation material (both inside the stud and between the studs).
  • Figure 4 An alternative is shown in Figure 4, in which the side walls are splayed, so that they taper inwardly towards the wall 2.
  • the internal stud width is greater away from the wall than near the wall.
  • the internal insulation sheets 7 can then be cut to match the shape and they can be inserted from one end (i.e. the top) of the stud and remain in position without additional fixing, for example avoiding the need for the flanges 8a, 8b of Figure 1 .
  • Figure 5 shows another variation where a corrugated side wall 4a,4b of the stud provides a fixing for the internal insulation.
  • the corrugation functions as a friction grip created in the side wall of the stud. This can be used to hold both the internal stud insulation and the insulation between studs.
  • Figure 5 also shows a further measure to reduce thermal bridging by creating an offset fixing tab that minimises contact with the cold external wall substrate.
  • the flanges 6a, 6b only need to be in close proximity to the wall along the locations where fixings are provided.
  • Figures 4 and 5 also show a slightly different design of fixing 5a, 5b having a double washer around the flange 6a, 6b which houses the screw fixings, in order to avoid cold bridging between the stud and the external wall.
  • the double washer can also surround the shaft of the screws, so preventing any metal-metal contact or metal-wall contact. By raising the stud slightly away from the wall using the washer on the wall side of the fixing, this also reduces the contact area for thermal conduction.
  • the wall insulation to be fitted between the studs can be cut in shape to match the stud shape.
  • the wall insulation should be sufficiently elastically deformable so that it can be inserted into position without needing to be slid in from the end (i.e. the top) of the stud, yet still remain held in place.
  • the splay angle ( Figure 4) or the corrugations ( Figure 5) are small enough, standard insulation sheets can again be used between the studs without cutting, and the shape mismatch also provides further retention of the wall insulation sheets, for example while outer wall boarding is applied.
  • the interior of the room can be finished by applying board material such as plasterboard over the studs and wall insulation. This can be fixed by self- tapping screws into the studs.
  • the spacing of the studs is designed to be suitable for the board material, for example spacing of 600mm or 450mm is typical for conventional timber stud walls finished with plasterboard.
