Definitions

  • the present invention relates to an insulating pane comprising at least two plane-parallel panes positioned in such a manner on each side of a closed spacer profile that a cavity is provided.
  • Traditional insulating panes comprise at least two plane-parallel panes of glass or another transparent material.
  • the panes are placed on each side of a spacer profile shaped to form the perimeter of a plane geometric figure, so that, when assembled, a cavity defined by the two panes and the spacer profile is provided.
  • This cavity is normally filled by air, typically atmospheric air, but may also be filled with a gas or a gas mixture having suitable heat transfer properties.
  • the shape and the size of the panes and the geometric figure created by the spacer profile are normally adapted to each other, so that the spacer profile, when the insulating pane is assembled, is positioned at the edge of the plane-parallel panes.
  • such insulating panes and thus the geometric figure formed by the spacer profile are rectangular, but they may in principle have almost any geometric shape, and circular insulating panes are thus for instance not unusual.
  • the spacer profile is typically of metal and has in itself a rectangular, tubular cross-section. It is desirable that the spacer profile has so small an abutment surface as possible against the window panes to avoid to the highest extent heat conduction between the two panes through the spacer profile and to avoid that the pane itself does not limit the effective window area more than absolutely necessary.
  • a pane In use such a pane is usually mounted in a sash which, on one hand, has an aperture which as to size and extent substantially corresponds to the effective window area of the insulating pane and which, on the other hand, is provided with a rabbet along the periphery of the aperture, said rabbet serving as abutment surface for the insulating pane and having dimensions corresponding to the overall dimensions of the insulating pane.
  • the insulating pane on one hand, lies in a recess corresponding to its own size, on the other hand substantially only abuts the abutment surface with the part, in which the spacer profile is present.
  • the pane is typically secured by means of securing beads fastened on the sash.
  • the rabbet at the lower edge of the insulating pane has been left out in certain windows to be mounted in oblique surfaces, as illustrated to the right in Fig. 1. Instead, the lower part of the sash is flush with the bottom of the rabbet all the way to the edge, and the insulating pane is placed in such a manner that it overlaps the sash all the way to its edge. The securing of the insulating pane is in this connection carried out by clamps. With this mounting, precipitation may run off the insulation pane, so that moisture accumulation and thus penetration of moist between insulating pane and sash is avoided.
  • the air in the part of the cavity adjacent the aperture will to a larger extent be heated by heat-conduction from the air in the room behind than will be the case for the part of the cavity overlapping the sash.
  • the heat-conducting spacer profile is moved further in on the sash, i.e. away from the aperture, the heat-conduction through the spacer profile will not occur in the immediate vicinity of the edge of the aperture of the sash, where the air with its content of moisture has access.
  • window panes mounted in sashes which, in the manner described above, have an aperture corresponding to the effective area of the insulating pane, i.e. the area within the figure formed by the spacer profile.
  • the invention overcomes this problem through an insulating pane according to the opening paragraph which is characterized in that in the cavity between the two plane-parallel panes and at a distance from the spacer profile an elongate, non-tubular wall member dividing the cavity is provided.
  • a large number of openings are provided in the elongate wall member, said openings being circular and having a diameter of less than 1 mm, preferably 0.2-0.4 mm.
  • the elongate wall member is preferably provided in the form of a metal strip having a thickness of approximately 0.05 mm.
  • the cavity between the panes being filled with air, preferably atmospheric air at normal atmospheric pressure (approximately 1013 hPa).
  • the elongate wall member extends along a number of the sides of the closed spacer profile.
  • the closed spacer profile substantially has the form of a rectangle, and the elongate wall member extends at a distance from and along a first side of the closed spacer profile and between two other mutually opposite sides.
  • the elongate wall member extends at the same distance, preferably 40 mm, from the sides of the closed spacer profile, along which it extends.
  • the elongate wall member may be positioned in such a manner relative to the sash that it does not affect the aesthetic appearance of the window seen from indoors, which is in particular advantageous, when the elongate wall member is opaque, which is for instance the case when said metal strip is used as the wall member.
  • Fig. 1 is a perspective sectional view through a window sash, on which an insulating pane according to the present invention has been mounted.
  • Fig. 1 shows, seen from the side and in perspective, a sectional view through a rectangular window sash 1, in which an insulating pane 2 according to the present invention has been mounted.
  • Fig. 1 three sash sides 1a, 1b, 1c are shown, attention being called to the fact that for illustrative reasons the middle of the insulating pane 2 as well as one sash side 1b have been removed.
  • sash sides 1a, 1b Of the four sash sides three, i.e. on the figure sash sides 1a, 1b, the fourth side not being shown, have the same L-shaped profile, whereas the last sash side 1c has a substantially rectangular profile.
  • the L-shaped sash profile thus provides a rabbet 3, in which the insulating pane 2 according to the invention has been mounted.
  • the insulating pane 2 is secured at the three sash sides 1b, 1b in the rabbet by means of a securing bead 4.
  • a sealing material (not shown) is provided in connection with the rabbet 3, the insulating pane 2 and the securing bead 4.
  • the last sash side 1c has a substantially rectangular profile.
  • the insulating pane 2 is secured at this sash side 1c not by means of a securing bead, but instead by means of clamps (not shown). Moreover, sealing material is provided between the insulating pane 1 and the sash side 1c.
  • the insulating pane 1 comprises a tubular spacer profile 5a, 5b, 5c having rectangular cross-section.
  • This spacer profile 5a, 5b, 5c is shaped into a closed, rectangular, geometric figure corresponding to the shape of the two individual panes 2a, 2b of the insulating pane.
  • the tubular spacer profile 5a, 5b, 5c will typically be made from stainless steel or aluminium, but other kinds of material might be applicable too, like for instance plastics or composite material.
  • the two panes 2a, 2b are in the preferred embodiment made from glass, but may in principle be made from any transparent material having sufficient strength.
  • the insulating pane overlaps the sash.
  • This overlap corresponds on the three sides 1a, 1b and the side not shown to the width of the tubular spacer profile 5a, 5b, 5c and to the width of the abutment surface 3a of the insulating pane against the rabbet 3. That is to say, the interior side of the rectangular geometric figure constituted of the tubular spacer profile flushes at the three sides substantially with the interior part of the sash, i.e. with the three sides of the aperture 7.
  • the overlap is bigger.
  • This overlap has the effect that there is part of the area of the insulating pane, in which the sunlight passing the insulating pane does not just continue through the aperture 7 to the room behind, but instead hits an area 6 of the sash, thus heating the sash member 1c.
  • the sash member 1c will moreover be heated by heat conduction from the room behind.
  • the heated sash member 1c will through the pane 2a heat the air in the area of the cavity adjacent the sash member 1c and between the two panes 2a, 2b. This heating occurs substantially by heat transmission through the pane 2a.
  • the heating may be such that the air in the area 9a adjacent the aperture 7 is heated to a larger extent than the air in area 9b adjacent the sash, because the heat conduction is higher through the pane 2a than through the sash member 1c.
  • the wall member 8 is in the embodiment shown in Fig. 1 positioned in such a manner that it extends along one side 5c of the tubular spacer profile and between to other sides, viz. the side 5b and opposite side (not shown).
  • the distance between the side 5c of the tubular spacer profile and the wall member 8 will normally be adapted so that the wall member 8 substantially flushes with the interior side of the sash member 1c.
  • the wall member flushes with a chamfering but might just as well flush with the side 11 of the sash itself.
  • the wall member 8 may in practice be designed in such a manner that it cannot immediately be distinguished from the tubular spacer profile 5a, 5b at the remaining three sides of the sash.
  • the distance will in practice be approximately 40 mm corresponding to the width of the sash member 1c.
  • the strip does not necessarily have to run smoothly in the longitudinal direction but may be bent in zig-zag shape or be provided with corrugations.
  • the term "elongate” is to be understood in relation to the strip itself.
  • the elongate strip is formed to a closed figure, for instance a circular or rectangular figure, for instance corresponding to the shape of the pane, in which it is inserted.
  • the wall member 8 is in the embodiment according to Fig. 1 secured directly to the panes 2a and 2b by means of an adhesive and sealing mass, for instance isobutylene-isoprene rubber or silicone.
  • the wall member 8 is designed as a metal strip, for instance of steel, stainless steel or aluminium, and has a thickness of 0.05 mm and a width corresponding to the distance between the two panes 2a and 2b.
  • a typical value for this distance and thus the width of the strip lies between 10 mm and 18 mm, typically 14 mm.
  • the wall member 8 also meets its primary function, i.e. to prevent convection in the cavity 9a, 9b between the two panes 2a, 2b to a sufficient degree, even though there is no airtight separation between the separated parts of the cavity 9a, 9b.
  • the wall member 8 is in a preferred embodiment of the invention provided with a large number of perforations.
  • the perforations are preferably made as circular openings having a diameter of between 0.1 and 0.4 mm.
  • the total area of these holes amounts to less than 1% of the complete area of the strip.
  • the perforations cause according to the tests a sound-attenuation in the order of up to 1.5 dB RW and typically between 0.4-0.5 dB RW.
