Definitions
- the invention relates to a multiple glazing delimiting two spaces with variable pressures independently of each other, in particular pressures which may differ more or less from each other.
- a typical example is the passenger cabin window of a commercial aircraft or business jet, cabin subject to pressurization while the aircraft can move at relatively high altitude, under lower pressure than on the ground.
- This multiple glazing comprises a thick outer slab which mechanically absorbs the different pressures inside and outside the enclosure, in particular by bending, and a thinner inner slab mounted parallel to the outer slab at a certain distance from that -ci, delimiting an intermediate air gap.
- the latter is connected to the interior atmosphere of the enclosure, by a through hole in the interior slab or the assembly joint of the multiple glazing.
- the inner slab is sized to replace the outer slab if the latter breaks, to absorb the mechanical stresses due to pressure differences.
- Face 1 F1 is in contact with the outside atmosphere
- face 4 F4 with the volume of the containment.
- the object of the invention is to provide multiple glazing of the type described above with a solar protection function. It is known in particular from document CA 2 763 423 A1 to coat one side of multiple aircraft glazing with a stack of thin solar protection layers, such as a silver tri-layer. Although this coating is not excluded by this document on face 2 F2, 3 F3 or 4 F4, the example of the document describes a coating on face 1 F1. It is moreover generally recognized that the positioning of a solar protection coating in a glazing is favorable as far upstream as possible from the solar radiation, a positioning facing 1 F1 therefore being the best for satisfying this criterion. There nevertheless remains a need to provide multiple glazing with a solar protection function in a way that is easier to implement, by allowing easy adjustment of the degree of filtration of solar radiation.
- a multiple glazing for delimiting two spaces with variable pressure difference, in particular an enclosure subjected to pressurization, comprising at least a first transparent slab intended to be in contact with the external atmosphere in the mounting position, and separated from a second transparent slab by an air gap, by means of a mounting joint in which a peripheral part of the multiple glazing is embedded, characterized in that it comprises at least one film of polymeric material, one main surface of which is functionalized to bring it into and keep it in adhesion with a substrate, and which comprises a layer or a stack of sunscreen layers, such a film of polymeric material being in adhesion to the main surface of the first slab opposite the second slab and/or on one of the two main surfaces of the second slab or both and/or the first slab is a vit laminated rage and such a film of polymeric material being in adhesion on a main surface internal to the laminated structure, of a constituent of the laminated glazing.
- a sunscreen adhesive film is adhered to face 2 F2, face 3 F3, face 4 F4 of the multiple glazing, or in the case where the first slab is laminated glazing, on a main face internal to the laminated structure (that is to say at a level of the thickness of the intermediate multiple glazing between face 1 F1 and face 2 F2). Thanks to the invention, the solar protection film(s) can easily be removed, replaced, in order to modify, adjust and adapt the degree of filtration of solar radiation, the solar factor, even in the event of damage to the film.
- a film of polymer material adheres to the main surface of the second slab facing the first slab.
- the film is then not subjected to the bending and mechanical stresses of the first slab which, alone, is subjected to pressurization, unlike the second slab. Additionally, solar radiation encounters the sunscreen layer or stack first and then the film adhesive, which is preferred.
- a film of polymeric material adheres to the main surface of the second slab opposite the first slab.
- the film is not subjected to the bending and mechanical stresses of the first slab.
- the film can be accessible, if necessary, in direct contact with the user, therefore less well protected.
- the first slab is a laminated glazing and a film of polymer material being in adhesion on a main surface internal to the laminated structure, of a constituent of the laminated glazing.
- the solar protection film is closer to solar radiation than in the first, and even more the second variant, it is here subjected to the bending and mechanical stresses of the first laminated slab, subjected to pressurization.
- the film is first glued to a sheet of glass or polymeric material, then this sheet is laminated.
- said main surface internal to the laminated structure, of a constituent be oriented towards the outer surface of the multiple glazing consisting of the first slab and not towards the air gap and the second slab, so that the solar radiation first encounters the solar protection layer or stack, before the adhesive layer of the film.
- a film of polymer material adheres to the main surface of the first slab facing the second slab.
- the film undergoes the strong mechanical stresses of the first slab, and its adhesive layer receives the solar radiation before its solar protection coating.
- the first slab has a thickness of between 1.5 and 20, preferably at most equal to 18, particularly preferably 16 mm. These relatively large thicknesses may be necessary to resist pressure differences on either side of the first slab, in particular to limit bending and the occurrence of heaving. This thickness is proportional to the main surface of the first slab.
- the second slab has a thickness comprised between 2 and 6 mm, preferably between 3 and 5 mm.
- the first slab is chosen from a sheet of polymer material such as poly(methyl methacrylate) (PMMA) in particular stretched, a sheet of glass such as soda-lime, aluminosilicate, borosilicate, optionally hardened, thermally toughened or chemically reinforced, and laminated glazing of at least two sheets of polymer material and/or of glass bonded together by means of at least one intermediate adhesive layer such as polyvinyl butyral (PVB), thermoplastic polyurethane (TPU), or ethylene-vinyl acetate copolymer (EVA) , silicone, cross-linked polyurethane or cross-linked polymethacrylates. Silicones can be used especially if a reinforced temperature resistance is sought.
- PMMA poly(methyl methacrylate)
- a sheet of glass such as soda-lime, aluminosilicate, borosilicate, optionally hardened, thermally toughened or chemically reinforced
- laminated glazing of at least two sheets of polymer material and/or of glass bonded
- the total thickness of polymer material is between 7 and 20, and in increasing order of preference, 18 and 16 mm.
- the first slab is a laminate of several sheets of glass, possibly a sheet of glass, the total thickness of glass is between 1.5 and 5 mm.
- the second tile is acrylic, such as stretched PMMA.
- the second slab or the mounting joint comprises a through hole of small diameter controlled, so that the air gap is at the same pressure as the volume delimited by the multiple glazing on the side opposite the first slab.
- a third constituent forms the main surface of the multiple glazing opposite the first slab, this third constituent being a sheet of polymer material separated from the second slab by another air gap.
- This third constituent is in contact with the interior volume of the passenger cabin, or equivalent.
- dust cover or “cover protection”.
- said third constituent is a sheet of polycarbonate (PC) or equivalent and supports an electrochromic function. This function allows the window to be concealed by electrically energizing the electrochromic layer.
- the invention also relates to the application of multiple glazing as described above, as glazing of a volume subjected to pressurization, in particular as aeronautical glazing, in particular as commercial aircraft glazing or jet glass. case, especially as a passenger cabin window.
- FIG. 1 is a cross section of said fourth variant of the multiple glazing of the invention
- FIG. 2 is a cross section of said first variant of the multiple glazing of the invention.
- FIG. 3 is a partial cross section of said third variant of the multiple glazing of the invention.
- a passenger cabin window 1 of a commercial aircraft consists of a first slab 2 of stretched PMMA with a thickness of between 9.5 and 11 mm, and a second slab 4 of stretched PMMA 4mm thick.
- the first slab 2 and the second slab 4 are embedded at their periphery in a silicone mounting joint 6, at a certain distance from each other constituting an air gap 3.
- the thickness of the first slab 2 is a function of the value of its main surface, to enable it to resist the pressurization of the cabin on the side of the second slab 4, by limiting its bending in the event of a variation in the pressure difference. on its two main surfaces.
- a small through hole, not shown, is made in the second slab 4, so that the air gap 3 is at cabin pressure on the side of the second slab 4, and the first slab 2 alone assumes the required mechanical resistance function. by the pressure differences on either side of the window 1.
