  • a packing 10 element in silicone material suitable for joining said sheet of glass 5 to said frame 20 and creating a seal between said sheet of glass 5 and said frame 20, for example to prevent water from leaking between the outdoor environment and the indoor environment.
  • the dimensions of the intermediate element 1 are comparable or greater than those of said internal profile 3 and said external profile 2.
  • FIG. 5 An example of embodiment of a frame 20, according to the present invention (figure 5) will be illustrated below by way of example only and which is not limiting.
  • a frame 20 is foreseen with a total thickness of about 78 millimetres and a total length of about 72 millimetres, which acts with a corresponding frame 120, with an overall thickness of about 65, 3 millimetres and a total length of about 80, 5 millimetres.
  • the two frames 20, 120 When put together, the two frames 20, 120 have an overall length of about 118 millimetres.
  • the frame 20 and the frame 120 each exhibit an intermediate element 1 in polyamide PA 6.6 with about 25% glass phase and thermal transmissibility of about 0,30 W/(m*K).
  • the intermediate element 1 of the frame 20 and of the frame 120 is completely filled with polyurethane foam PUR 447 / 900-1, with a density of about 50 Kg/m 3 and thermal conductibility, in other words thermal transmissibility, of about 0,030 W/(m*K).
  • the frames 20 and 120 have an internal profile 3 made of soft wood, for example conifer wood, with thermal transmissibility of about 0,13 W/(m*K).
  • the frames 20 and 120 also have an external profile 2 made of aluminium, with thermal transmissibility of about 160 W/ (m*K).
  • a flow of heat is obtained between the INT and EXT of about 6, 28 W/m and a corresponding global thermal exchange coefficient of the whole of the frame 20 and 120 of about 1, 2 W/ (m 2 *K).
  • an insulating element 11 that is substantially "herringbone” packing, made of Deventer Purene S TPE (thermoplastic elastomer) microfoam, with a thermal transmissibility of about 0,077 W/ (m*K), a flow of heat is obtained between the INT and EXT of about 6, 20 W/m and a corresponding global thermal exchange coefficient of the whole of the frame 20 and 120 of about 1, 1 W/ (m 2 *K).
  • Purene S is an effective material for heat insulation, which can easily absorb thermal unbalances and be welded to form a continuous cordon that is perfectly hermetic along the whole of the perimeter of the window.
  • the thickness needed for the external profile is reduced; in fact it is made for example of aluminium, and a reduction in its thickness also leads to a reduction in the thermal transmissibility from the outdoor environment to the inside environment, in other words the dew point associated with the frame moves towards the outdoor environment.
  • an external profile thickness is envisaged that is strictly necessary for the protection of the frame and the window from atmospheric agents, without additional thicknesses resulting from working requirements of the frame itself.
  • the connecting means such as the polyurethane foam
  • the connecting means allows a considerable reduction in the global thermal exchange coefficient of the frame, consequently allowing the flow of heat between the indoor environment and the outdoor environment to be reduced drastically, thus achieving efficient thermal cutting.
  • the polyurethane foam is foreseen as a joining means between the intermediate element in polyamide and the external profile in aluminium thanks to its ability to "cling" to the surfaces of the interspaces of the frame, as well as as an effective thermally insulating element.
  • the polyurethane foam is for example foreseen in contact on the one side with a conducting material, such as the external profile in aluminium, and on the other with an insulating material, such as the intermediate polyamide, so that the flow of heat is advantageously limited and/or stopped.
  • a conducting material such as the external profile in aluminium
  • an insulating material such as the intermediate polyamide
  • polyurethane foam is also foreseen in the interspaces formed completely with the polyamide, such as the second, previously described interspace, to increase the heat insulation effectively.
  • the intermediate element in polyamide lends itself perfectly to joining two different materials, avoiding heat bridges from forming, both with the heat and cold, guaranteeing perfect thermal separation and, with the addition of the packings 6, 7, 8 and 9 in the most appropriate parts, a perfectly hermetic seal.
  • the presence of the intermediate element 1 in polyamide also gives the frame 20 elevated static resistance.
  • the first and second interspace defined by the intermediate element 1 are, as said, advantageously foamed, improving the qualities of heat insulation and resistance.
  • an interspace of air is foreseen between aluminium and polyamide and between polyamide and wood to prevent condensates from forming in the profiles and protect the wood over the years.
  • the fastening screws and hardware are fixed directly onto the intermediate layer in polyamide, which avoids direct contact with the aluminium and consequent heat bridges.
  • the external profile 2, the intermediate element 1 and the internal profile 3, conveniently shaped at the beginning and assembled with respective angular couplings, can be used to construct each fixed, moving, vertical and horizontal part of frames 20 for fixtures of windows and French windows, both sliding and with wings.
  • wood and polyamide are connected in the corners with three angular couplings: one for the profile in aluminium, a second one for the intermediate element in polyamide and a third one for the profile in wood, created with an insert in glued laminated wood.
  • the same type of angular coupling is present, for example, in the frame of the window.
  • the frame according to the present invention allows extremely innovative windows and French windows to be made to protect indoor environments and make them comfortable.
  • the frame is created using wood and aluminium, which are materials suitable for satisfying these needs thanks to the resistance and stability of the aluminium and the natural heat and energy of the wood.
  • the internal profile in wood can be made in a wide variety of colours and types of wood for all tastes and needs: local pinewood, Douglas, oak and cedar for the inside, combined with a wide range of RAL colours for the outside in aluminium.
  • the frame is surprisingly resistant to bad weather and very easy to clean. This is not only thanks to the method used to make the profiles that form it, but also thanks to the considerable resistant qualities of the aluminium on the outside, which represents a safe protection in all weather conditions.
