Definitions

  • Hollow chamber profiles for a window or a door are produced in particular from thermoplastic material and are used on a large scale for the production of plastic windows and plastic doors. These profiles are predominantly manufactured from hard PVC (PVC-U) by extrusion. As a rule, they have several hollow chambers that are separated from one another by inner webs. By arranging a number of hollow chambers one behind the other in the direction of heat transfer through the profile, i.e. from the room-side outer wall to the weather-side outer wall, a high level of thermal insulation is achieved in such plastic windows and plastic doors.
  • PVC-U hard PVC
  • the present invention comes in, which is based on the object of providing a hollow chamber profile for a window or a door which at least partially overcomes the disadvantages of the prior art.
  • the inventive Hollow chamber profile for a window or door with moderate use of material and high possible extrusion speed ensure improved thermal insulation properties.
  • the object of the present invention is to provide a frame assembly for a window or for a door which comprises at least one profile section of such a hollow chamber profile.
  • an insulating element designed as a plastic film provided with a metal layer at least on one side is arranged in one of the hollow chambers of the hollow chamber profile.
  • a plastic film provided with a metal layer has a high degree of transmission in the visible range of the electromagnetic spectrum in the infrared spectral range, a high level of reflection and, associated therewith, a low emissivity. Accordingly, such a film has the effect of lowering the emissivity in the wavelength range from 3 ⁇ m to 50 ⁇ m, in particular in the region of the maximum of the thermal radiation at room temperature (approximately 10 ⁇ m).
  • a metal layer for example an aluminum, silver, gold and / or copper layer, is applied to at least one side of a plastic film to generate the high reflection in the infrared spectral range.
  • the metal layer can have a thickness in the range from 5 nm to 200 ⁇ m, preferably in the range from 10 nm to 25 nm.
  • the metal layers are preferably coated with a protective layer (in particular with an antioxidant effect), a decorative layer, a colored layer, a lacquer layer, a functional layer and combinations of the layers mentioned in one or more layers.
  • the present invention lies in the provision of a hollow chamber profile for a window or a door made of a thermoplastic plastic, the thermoplastic plastic forming the inner walls and the outer walls of the hollow chamber profile, the inner walls and the outer walls surrounding the hollow chambers of the hollow chamber profile and at least one the hollow chambers of the hollow chamber profile at least one insulation element is inserted, and the hollow chamber profile is characterized according to the invention in that the at least one insulation element is designed as a plastic film provided with a metal layer on at least one side.
  • the present invention relates to a frame assembly for a window or a door, which comprises at least one profile section of a hollow chamber profile according to the invention.
  • the plastic film is provided with a metal layer on both sides.
  • This metal layer can also have a thickness in the range from 5 nm to 200 ⁇ m, preferably in the range from 10 nm to 25 nm.
  • the metal layers on both sides of the plastic film can be the same or different.
  • the hollow chamber profile can be produced by an extrusion process known per se.
  • the preferred material for the hollow chamber profile is polyvinyl chloride (PVC), in particular hard PVC (PVC-U) or post-chlorinated PVC.
  • PVC polyvinyl chloride
  • PVC-U hard PVC
  • PVC-U post-chlorinated PVC.
  • the material can preferably also be fiber-reinforced, in particular glass fiber-reinforced.
  • the material of the plastic film is chosen so that it does not appear disruptive when welding profile spars from the hollow chamber profile.
  • the plastic film has a material thickness of not more than 500 ⁇ m.
  • the material thickness of the plastic film is particularly preferably in a range from 100 ⁇ m to 450 ⁇ m, in particular in a range from 200 ⁇ m to 400 ⁇ m.
  • Such a thickness of the plastic film offers sufficient stability with a material expenditure that is considerably reduced compared with the corresponding inner webs of the hollow chamber profile.
  • the plastic film is connected at least in sections to at least two opposing walls of the hollow chamber.
  • the plastic film can only rest against the walls of the hollow chamber or can also be welded to them. It can be both inner walls and outer walls of the hollow chamber profile according to the invention.
  • the plastic film arranged in the main hollow chamber, preferably in the main hollow chamber, contributes little or no contribution to the statics of the hollow chamber profile and the frame assembly formed from sections of the hollow chamber profile. So that the plastic film can remain stable in position in the respective hollow chamber, it is therefore preferred if the insulation element rests against at least two opposing inner walls of the hollow chamber. It is sufficient here if the insulation element rests against the inner walls of the hollow chamber profile only in sections.
  • the hollow chamber profile according to the invention and individual parts thereof can also be produced line by line or layer by layer using a line-building or layer-building production process (e.g. 3D printing), but production by means of extrusion or coextrusion is preferred.
  • a line-building or layer-building production process e.g. 3D printing
  • the frame assembly 1 according to the invention shown differs from that according to FIG Fig. 1 therein, on the one hand, that the number of hollow chambers of the hollow chamber profile 2 is lower.
  • the main hollow chamber 3 ′′ of the hollow chamber profile 2 according to the FIG Fig. 2 embodiment of the present invention shown is formed wider.
  • the main hollow chamber 3 "is surrounded by the inner wall 4 and also by the outer walls 5 ', 5" and 5'" Fig. 2
  • an insulation element 12 is inserted in the main hollow chamber 3 ′′.
  • the insulation element 12 is in the embodiment shown in FIG Fig. 2 embodiment shown as a plastic film 12 coated on both sides with a metal layer and shown in FIG Fig. 3 shown in a perspective view.
  • plastic film 12 'metallized on both sides in the hollow chamber of the glazing bead 9 which has a perforation along which it is folded so that the plastic film 12 "is also essentially V-shaped.
  • the plastic film 12" has a thickness of 220 ⁇ m, the metal layers also made of copper on both sides of the plastic film 12 ′′ each having a thickness of 11 nm.
  • the plastic component of the plastic film 12 ′′ metallized on both sides is formed from post-chlorinated polyvinyl chloride.
  • the plastic film 12 ′′ metallized on both sides is brought into the appropriate shape by folding and pushed into the hollow chamber of the glazing bead 9.
  • the present invention has been described by way of example with reference to sash profiles of a window. It goes without saying that the present invention can also be correspondingly applied to other hollow chamber profiles, in particular window frame profiles, mullion and blind mullion profiles and window frame, frame or sash profiles of a door.
