Definitions

  • the invention relates to a glazing element in particular for use in a passive house according to the preamble of claim 1
  • a 3-pane glazing element with a low heat transmission coefficient UQ (previously kern) is known.
  • This comprises three glass panes separated by gas spaces.
  • An inner and an outer glass pane are each provided with a transparent, heat radiation reflecting layer, a so-called thermal insulation layer, on the sides facing the glass interspaces.
  • the outer glass pane is on its outside facing the atmosphere with a low-emitting layer, which in turn is covered with a hydrophobic layer.
  • the low-emitting layer reduces the frequency of dew fogging on the outer surface, since it reduces the radiation of heat from the outer surface of the glazing to the sky and the surrounding area, thus weakening the lowering of the temperature of the outer surface.
  • the hydrophobic layer has a self-locking effect on the underlying low-emissivity layer.
  • a disadvantage of the glazing element known from EP 0 854 264 A1 is, in particular, that, due to the low-emitting layer on the outer surface in the event of solar radiation, it absorbs sun rays in the thermal insulation layer on the side facing the gas space to form a heat accumulation Gas gap comes. This leads to an early material fatigue of the pane edge bond and thus a reduced aging resistance of the glazing and the window.
  • the solution proposed in EP 0 854 264 AI is complex and therefore expensive to manufacture.
  • dew fog should not appear on the outer surface of glazing without a low-emissive layer on the outer surface.
  • the fact that it occurs more frequently, especially in glazing elements with a low U G value, is an indication that the Ug value determination is incorrect with the applicable DIN standards; it does not properly take into account the heat radiation from the outer surface to the sky and the surroundings.
  • the object of the present invention is therefore to provide a glazing element with the criteria required today for passive houses, in which a heat build-up does not occur in the outer glass interspace and thus the aging resistance of the glazing element and the window is guaranteed and in which at the same time the dew fog on the outside of the Glazing element is reduced.
  • no heat insulation layer is provided on the surfaces of the middle pane and the outer pane adjoining the second, outer intermediate space. This reduces the heat build-up in the glazing element. At the same time, the fogging is counteracted.
  • the effect of the glazing element according to the invention is advantageously improved by a suitable choice of the emissivity and the solar transmittance of the poor insulation layer and the low-emissivity layer.
  • the panes of the glazing element designed according to the invention can consist of white or float glass. A combination of the different types of glass is also provided.
  • a filling of the spaces between the panes with air or a noble gas such. B. krypton or argon to improve the thermal insulation is advantageous.
  • One space can be filled with air and the other with an inert gas or a gas mixture.
  • Fig. 1 is a schematic sectional view of an embodiment of the invention
  • the glazing element 1 according to the invention shown in FIG. 1 is particularly suitable for use in a so-called passive house.
  • a passive house is characterized by a heat-saving design, which only allows a maximum consumption of 10 1 / year of heating oil or 10 m 2 / -T ⁇ hr natural gas per square meter of living space.
  • highly thermally insulated window panes with a maximum possible solar energy transmission that meet the following criteria:
  • U G represents the thermal transmittance coefficient of the glazing (formerly k G value) according to the Euro standards EN DIN 673, 674 and 675 and g the total energy transmittance of the glazing according to the Euro standard EN DIN 410.
  • the comfort criterion describes the energy loss of the glazing element
  • the energy criterion describes its energy balance from energy loss and energy gain through solar radiation.
  • the glazing element 1 according to the invention shown in FIG. 1 consists primarily of three panes 2, 3, 4, which can consist of float or white glass.
  • the thickness of the transparent panes 2, 3, 4 is preferably at least 3 mm.
  • the choice of material for panes 2, 3, 4 is arbitrary, for example all three panes 2, 3, 4 can be made of white glass or float glass. However, it is also possible, for example, to produce a single pane 3 from white glass and the other panes 2 and 4 from float glass.
  • a first intermediate space 5 is formed between the first, inner disc 2 and the second, central disc 3, and a second intermediate space 6 is formed between the central disc 3 and the third, outer disc 4, which space the discs 2 and 3 and 3 and 4 from each other ,
  • the width of the spaces 5, 6 is preferably between 12 mm and 16 mm.
  • the spaces 5, 6 can be filled with a noble gas such as argon or krypton or mixtures of these noble gases instead of air. It is also possible to use the spaces 5, 6 to provide different fillings; for example, the space 5 can be filled with argon and the space 6 with krypton.
  • a noble gas such as argon or krypton or mixtures of these noble gases instead of air. It is also possible to use the spaces 5, 6 to provide different fillings; for example, the space 5 can be filled with argon and the space 6 with krypton.
  • a thermal insulation layer 7 is applied to the first, inner pane 2.
  • the thermal insulation layer 7 preferably consists of a layer system based on silver.
  • the emissivity ⁇ is at most 0.05, the solar transmittance ⁇ e is at least 54
  • a low emissivity ⁇ of the thermal insulation layer 7 brings about a reduction in the U G value of the glazing element 1.
  • the solar transmittance ⁇ e is that part of the incident solar radiation which penetrates the thermal insulation layer.
  • the solar transmittance is defined according to the Euro standard EN DIN 410 as follows:
  • S ( ⁇ ) means the spectral distribution of solar radiation.
  • a low-emitting layer 8 preferably based on an electrically highly conductive semiconductor or a noble metal layer system, is applied to the third, outer pane 4.
  • the emissivity ⁇ of the low-emissivity layer 8 is at most 0.2, the solar transmittance ⁇ e is at least 67%.
  • the low-emitting layer 8 is preferably additionally provided with a dirt-repellent layer 9 covered, which smoothes the low-emitting layer 8.
  • the dirt-repellent layer 9 has the advantage that it has a self-cleaning effect and makes the outer pane 4 easier to clean.
  • the disks 2, 3, 4 are spaced apart from one another by spacer frames 10 which are only shown schematically.
  • the panes 2, 3, 4 can be connected to each other with the spacer frame 10 by adhesive sealant, not shown.
  • the spacer frame can include a desiccant.
  • the low-emitting layer 8 on the outer surface of the glazing element 1 can both reduce the frequency of dew fogging and reduce the U G value of the glazing element 1, ie improve it.
  • the solutions mentioned are more expensive.
  • solar radiation can lead to a build-up of heat in the intermediate space 6 between the panes 2 and 3, as a result of which the aging resistance of the glazing element 1 is impaired.
  • the above-described glazing element 1 is therefore proposed, which, as already explained, has only one heat insulation layer 7 on the first inner pane 2 or second, middle pane 3 facing the first space 5, but no further heat insulation layer on one of the second space 6 facing surface of the second, middle pane 3 or the third, outer pane 4.
  • the glazing element 1 according to the invention has the advantage that both the criteria of passive house suitability and the other advantages of a low-emitting layer 8 on the outer pane 4 of the glazing element 1 , namely the significantly reduced frequency of dew fogging as well as a heat loss which is quasi independent of the weather and the installation position and which is 10% less than the annual average compared to the calculation according to the current DIN standards.
  • the panes 2, 3, 4 are preferably made of float glass. Only in the last exemplary embodiment is the middle pane 3, as indicated by the asterisk ( * ), made of white glass.
  • the spaces 5, 6 are filled with different gases or gas mixtures, different combinations of air (L), argon (Ar) and krypton (Kr) being specified.
  • the g-value, ie the total energy transmittance, of the respective glazing element 1 is given, which is essentially determined by the solar transmittance ⁇ e
  • the third and fourth columns of the table meet the requirements of the Euro standards the real measured U G values, ie the Thermal transmittance included.
  • the fifth column contains the U G value according to the state's computed calculation. This must meet the first criterion of the passive house (comfort criterion) mentioned above.
  • the last column of the table contains the second criterion of the passive house (energy criterion).
  • the glazing element according to the invention therefore enables a window pane that is suitable for passive houses, which can be produced inexpensively and which, due to the heat build-up avoided, ensures a high degree of resistance to aging while simultaneously reducing the frequency of dew fogging on the outside and ensuring compliance with the energy criteria.
