  • the above method teaches how to calculate the effective laminate thickness of a laminated assembly comprising the first glass pane and one glass sheet. For laminated assemblies comprising more than one glass sheets, the calculation method between 2 panes, must be iteratively continued until a unique effective thickness, hef, has been calculated and all panes and corresponding polymer interlayer(s) have been considered.

  • the flexural stiffness of the first glass pane, K1, and the flexural stiffness of the second glass pane, K2, may be different.
  • the present invention also relates to the use of an insulated glazing unit as defined above, to close the opening of a partition separating an exterior space from an interior space, and preferably wherein the first glass pane is facing the exterior space.

  • the first and second glass panes of the IGU of the present invention as well as the additional glass sheets within the laminated assembly can be prestressed glass.
  • prestressed glass it means a heat strengthened glass, a thermally toughened glass, or a chemically strengthened glass.
  • the chemical strengthening of a glass article is a heat induced ion-exchange, involving replacement of smaller alkali sodium ions in the surface layer of glass by larger ions, for example alkali potassium ions. Increased surface compression stress occurs in the glass as the larger ions "wedge" into the small sites formerly occupied by the sodium ions.
  • Such a chemical treatment is generally carried out by immerging the glass in an ion-exchange molten bath containing one or more molten salt(s) of the larger ions, with a precise control of temperature and time.
  • Aluminosilicate-type glass compositions such as for example those from the products range DragonTrail ® from Asahi Glass Co. or those from the products range Gorilla ® from Corning Inc., are also known to be very efficient for chemical tempering.
  • the laminated assembly within the IGU of the present invention may typically comprise from 1 to 7 additional glass sheet(s), preferably from 1 to 4 additional glass sheet(s), more preferably from 1 to 2 additional glass sheets and corresponding additional layers of polymer interlayer(s).

  • the thicknesses are measured in the direction normal to the plane, P.
  • the at least one polymer interlayer comprises a material selected from the group consisting of ethylene vinyl acetate, and/or polyvinyl butyral, more preferably polyvinyl butyral.
  • the polymer interlayer is also designated as a "bonding interlayer" since the polymer interlayer and the glass pane form a bond that results in adhesion between the glass pane and the polymer interlayer
  • the polymer interlayer to be used in the present invention is a transparent or translucent polymer interlayer.
  • the polymer interlayer may be colored or patterned.
  • Typical thicknesses (measured in the direction normal to the plane, P) for the at least one polymer interlayer, h v are 0.3 mm to 3.5 mm, preferably 0.75 mm to 1.75 mm.
  • Commercially available polymer interlayers are polyvinyl butyral (PVB) layers of 0.38 mm, 0.76 mm, 1.52 mm, 2.28 m and 3.04 mm. To achieve the desired thickness, one or more of those layers can be used.
  • polyvinyl butyral polymer interlayers are preferably used.
  • Polyvinyl butyral or PVB is a resin known for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility. It is prepared from polyvinyl alcohol by reaction with butyraldehyde. Trade names for PVB-films include KB PVB, Saflex, GlasNovations, WINLITE, S-Lec, Trosifol and EVERLAM.
  • the bonding process takes place under heat and pressure also designated as autoclave process which is well known in the art.
  • the PVB interlayer becomes optically clear and binds the two panes of glass together. Once sealed together, the laminate behaves as a single unit and looks like normal glass.
  • the polymer interlayer of PVB is tough and ductile, so brittle cracks will not pass from one side of the laminate to the other.
  • Another process known in the art and preferred for the present invention is the autoclave free laminated glass production. This process reduces energy costs but has the drawback of limiting the types and thickness of polymer interlayer. Autoclave free oven makes preferentially EVA and dedicated PVB laminated glass. In such case, to achieve the desired thickness and security requirements, one or more of those autoclave free polymer interlayers can be used.
  • Another process to produce a laminated glass is the vacuum bag process.
  • the present invention also applies to multiple glazing units comprising three or more panes, defining bounding insulating or non-insulating internal spaces.
  • a third additional glass pane can be coupled to the outer pane faces (23) of second glass pane along the periphery of the IGU via another peripheral spacer bar, creating a second internal volume sealed by a peripheral edge seal. Said peripheral spacer bar maintained a certain distance between the third glass pane and the at least one of the outer pane face one of the first and second glass panes.
  • the insulated glazing unit comprises a spacer (3) maintaining the first glass pane and the second glass pane at a certain distance, D, and defining an internal volume, V, extending between the first and second glass panes from the spacer to the peripheral edges.
  • the spacer has consequently a surrounding shape which spaces apart the glass plates on their periphery. It can be made of one piece or can alternatively comprise a plurality of elements having their extremities abutted to form the surrounding shape.
  • the spacer can be metallic, polymeric, a composite material reinforced by glass fibres or a mix of several of these materials.
  • the spacer can be hollow in order to be able to receive for example some drying material. Such spacer is then perforated to allow the drying material to trap water vapor that is coming in the cavity of the IGU.
  • the spacer is inserted between the glass plates generally by means of butyl or silicone adhesive strips. Thereby, forming an encompassing surrounding edge joint, as usual for insulated glazing, which is provided with a cordon of sealant.
  • the internal volume, V between the glass plates is sealed with respect to the exterior in a gas and moisture-sealed type manner.
  • Said internal volume is filled with a predetermined gas selected from the group consisting of air, dry air, argon (Ar), krypton (Kr), xenon (Xe), sulfur hexafluoride (SF6), carbon dioxide or a combination thereof or it can be (partially) evacuated.
  • Said predetermined gas are effective for preventing heat transfer and/or may be used to reduce sound transmission.
