Definitions

  • the present invention relates to insulating insulating glazing increased thermal in the marginal areas of the glazing, including at minus two sheets of glass and a compound metal spacer a hollow profile whose cross section narrows towards the periphery of the glazing, the grooves formed by the inclined surfaces of the profile hollow and the opposite surface areas of the glass sheets being filled an adhesive sealant.
  • the spacing frame is generally composed of a hollow aluminum profile assembled to glass sheets with adhesive layers.
  • the spacing frame is slightly offset from the edges of the glass sheets towards the surface of visibility, so that it forms on the edge between the perimeter surface of the spacer frame and the interior surfaces of the two glass sheets a hollow space which is filled with an adhesive sealant hardening. Due to this construction and thermal conduction resulting increase in the marginal zone, the thermal insulation effect insulating glass at the edge is significantly reduced compared to the remaining glazing area. This has the consequence that, in the case of low outside temperatures, the insulating glass on the side facing the piece are cooler on the edge than in the central area so the glazing may fog up at the edge since at this point the humidity of the air condenses on these colder marginal zones.
  • the frame spacing in a metal of lower thermal conductivity.
  • the EP 0 403 058 A1 and WO 93/19274 describe insulating glass of the type mentioned in the case of which, to increase the effect thermal insulation in the marginal area, the spacing frames are formed from thin-walled hollow sections of stainless steel with a lower thermal conductivity than, for example, aluminum.
  • the width of the adhesion surfaces between the spacing frame and the glass surfaces decreases. That may, however, in certain circumstances lead to a weakening of the bonded assembly and, in the long term, adversely affect the sealing effect. It is certainly possible to remedy it by increasing the height of the frame spacing, but the visible edge of the insulating glass will be more large. It is however of major interest to keep the edge visible and therefore the depth of insertion of the insulating glass in the frame as low as possible.
  • the usual sealing systems for glazing insulators have a primary sealing medium of about 2 to 4 mm and made of butyl and a secondary sealing means attached thereto made of another adhesive system which is injected into the grooves.
  • this second adhesive system it is in principle known and complies with instructions issued by the adhesive manufacturer to place the spacing frame between the glass sheets as well as possible towards the interior so that the width covered with glue on the glazing at least 2 mm more than the width covered with adhesive on the frame spacing. In this way sufficient adhesion of the glue to the glass will be guarantee.
  • the object of the invention is to design an insulating glazing of the type mentioned in the preamble so that even in the case of a relatively low height of the spacing profile, it is possible to achieve satisfactory and lasting sealing of the glazing.
  • the adhesion surface on the glass sheets is more enlarged so that it is possible, in this way, to achieve the same adhesion conditions that so far on the glass sheets and place, by the same occasion the spacing frame more on the edge, whereby the edge visible adhesion is reduced as a whole and a lower depth of insertion of insulating glass in the frame thus becomes possible.
  • the drawing is a sectional view of the marginal area of a glazing insulating.
  • the insulating glazing comprises the two glass sheets 1 and 2 which are made of float glass, for example, of a thickness of 6 mm. Between the two glass sheets 1, 2 is placed at the edge a spacer frame 3 made of a hollow profile 4 whose hollow interior is in communication via the openings 5 with the air space 6.
  • the hollow interior of the hollow profile 4 is filled with a molecular sieve or another dehydrating agent 7.
  • a sealing system comprising a primary sealing means 8 and a secondary sealing means 9 is used to bond the spacer frame 3 and the two sheets of glass and to make the edge waterproof.
  • the primary sealing means 8 consists of a material butyl sealant, for example with a width of 2 to 5 mm, arranged on along the edges of the hollow profile 4 near the air space 6.
  • the spacer frame is first coated on both sides of a butyl bead and the two glass sheets are then pressed against the coated spacing frame.
  • the hollow profile 4 forming the spacer frame 3 has a cross section such as the side walls glued to the glass sheets form, in the part close to the air space, a right angle with the wall 11 limiting the air space.
  • the side walls are provided of the primary sealing means.
  • the parts of the side walls of the profile hollows 4 attached thereto are inclined inward so that the cross section of hollow section 4 tapers towards outside.
  • These inclined surfaces 12 represent the adhesion surfaces of the spacer frame for the secondary sealing means and form, with the opposite marginal areas of the glass sheets, grooves in which is injected the sealing material of the sealing means secondary 9.
  • the glass sheets 1 and 2 are chamfered on along their periphery at an angle a of about 30 °.
  • This chamfering has for consequence that the width B of the inclined marginal surfaces 10 available for the secondary sealing medium is enlarged by 40%. he is also possible to achieve sealing and bonding sufficient even when the adhesive sealing material is only injected in the two grooves between the inclined side walls 12 of the hollow profile and the chamfered surfaces 10 of the glass sheets.
  • the outer side 13 may be free of adhesive sealant. If the hollow profile 4 furthermore has a thin wall thickness and is made of a metal of low thermal conductivity, insulating glazing having an effect particularly good thermal insulation in the marginal area and by the same occasion a relatively narrow edge, can in this way be manufactured.
