Definitions
- the invention relates to the field of double glazing with thermal insulation function.
- the standard thermal insulating glazing consists of a double glazing (in English "Double Glazing Unit" - DGU -), which usually consists of two glass panels of varying thickness mounted parallel to each other. with a spacing of 16 mm in general, filled with air or a gas such as argon. This configuration helps to minimize heat transfer between indoors and outdoors, reducing heat loss and improving thermal comfort and energy savings.
- double glazing is used as side glazing, where it is usually provided with coating (s) to improve thermal energy performance, for solar control and low-emissivity.
- Solar control is the reflection and filtration of solar radiation to reduce the heating induced inside a closed volume
- low-emissivity is the reflection of thermal radiation from an enclosure to retain heat.
- one of the disadvantages of using such highly selective coatings for solar control and low emissivity is the attenuation of the GSM frequency in the GHz frequency band. This is due to the presence of several metal layers in the coatings, which thanks to their conductivity behave as perfect reflectors of electromagnetic waves of the order of GHz.
- conductive coating s
- this objective has been achieved by the invention, which consequently relates to an insulating glazing with high transmission of GSM waves, consisting of a first and a second glazing parallel to one another. other, and each having a thickness at most equal to 10 mm, separated from one another by a gas layer, characterized in that the gas layer has a thickness at most equal to 10 mm.
- the gas layer can consist of air or gas such as argon, xenon, krypton, or under vacuum.
- the first and second glazings comprise sheets of polymer material and of mineral glass, the Fe content of which is at most equal to 0.1% by weight.
- the first and second glazings are, independently of one another, monolithic, that is to say made up of a single transparent rigid sheet, or laminated, more precisely then made up of two rigid sheets. transparent glued to each other by an adhesive interlayer.
- a transparent rigid sheet is made of a polymer material such as polymethyl methacrylate (PMMA), polycarbonate (PC), polyurethane (PU) for example, or in mineral glass such as soda-lime, aluminosilicate, borosilicate ...
- An intermediate adhesive layer is for example made of polyvinyl butyral (PVB), thermoplastic polyurethane (TPU) or ethylene - vinyl acetate (EVA).
- PVB polyvinyl butyral
- TPU thermoplastic polyurethane
- EVA ethylene - vinyl acetate
- one of the first and second glazing units, or both has (have) a thickness at most equal to 5 mm.
- This relative fineness of the double glazing is sufficient to guarantee in many applications the required mechanical resistance while limiting the weight of the glazing. It is also favorable to the transmission of GSM waves.
- the gas layer is under vacuum and of thickness at most equal to 0.3 mm.
- Such a thin vacuum gas sheet provides thermal insulation equivalent to that of a gas sheet at atmospheric pressure much thicker, as well as a transmission of GSM waves close to that of a massive (monolithic) glazing of thickness. equal to the total thickness of the two glazing of the double glazing.
- At least one of the first and second glazings is a laminated glazing consisting of two sheets of mineral glass bonded to one another by means of an intermediate adhesive layer.
- Laminated glazing provides resistance to penetration / burglary at a reasonable thickness and weight per unit area.
- the intermediate adhesive layer is then preferably chosen from polyvinylbutyral (PVB), thermoplastic polyurethane (TPU), ethylene-vinyl acetate (EVA).
- PVB polyvinylbutyral
- TPU thermoplastic polyurethane
- EVA ethylene-vinyl acetate
- the insulating glazing comprises at least one thin solar control layer and / or a thin low-emissive layer, which has (have) been subjected (s) to partial laser ablation to allow GSM waves to pass.
- the terms “thin layer” refer to a single layer, or even more often to a stack of several layers (total) thickness of the order of a few tens of nanometers at most.
- the stack often comprises an alternation of electrically conductive layers, including metallic, and dielectric.
- the function of these thin layers is to reflect different thermal radiations in the infrared, as mentioned previously (solar radiation, internal heat of a closed volume).
- These thin layers not transmitting electromagnetic waves such as GSM, it is possible, according to this variant of the method of the invention, to remove parts thereof preferably regularly distributed over the entire surface of the thin layer, by laser ablation, which allows GSM waves to pass.
- Another object of the invention consists in the application of an insulating glazing described above, as glazing for land, water or air vehicles, or as glazing for buildings, and in particular as side glazing for trains.
- the invention is illustrated by means of the following exemplary embodiments.
- the transmission of GSM waves is measured through double glazing units each consisting of two laminated glazing units separated by an air space.
- each double glazing The constitution of each double glazing is shown in the table below.
- the first laminated glazing consists of two sheets of glass designated by I (Glass I) and II (Glass II) bonded to each other by PVB, the second laminated glazing of two sheets of glass designated by III (Glass III) and IV (Glass IV) also glued to each other by PVB.
- Glass is soda ash for lack of precision, or float borosilicate.
- the thicknesses of all the components of each double glazing are indicated in mm.
- All double glazing has a total thickness of
- the minimum transmission (in dB) of GSM waves is recorded, by values of frequency domains or discrete frequencies (in GHz), for each of the six double glazing, in the table below.
- the "thick PVB” and “thick glass” double glazing which has an air gap of about 10 mm, have better GSM transmission in the critical frequency range of 3.4-3.8 GHz, compared to standard double glazing (double glazing). 14 mm air).
- the situation in this regard is even better by replacing soda lime glass with float borosilicate (Borosilicate PVB thick, and Borosilicate thick glass).
- Borosilicate glass also achieves good GSM transmittance for a frequency up to 28 GHz, which is critical for future 5G applications. It is possible to considerably improve the GSM transmittance even with soda-lime glass only by reducing the thickness of the air space. However, the loss of Ug coefficient (thermal insulation property of double glazing), passing from an air space of 16 to 10 mm, is only 0.2 W / m 2 K. In a second series of tests, the transmission of GSM waves is measured through double glazing each consisting of two glazing separated by a vacuum air gap on the one hand, at atmospheric pressure on the other hand, and at through monolithic mineral glass glazing.
- each glazing is recorded in the table below.
- the first glazing is designated by I (Glass I) and the second glazing by II (Glass II).
- the glass is soda-lime (PLC for Planiclear® marketed by the Company Saint-Gobain Glass France), or floated borosilicate.
- the thicknesses of all the components of each double glazing are indicated in mm.
- the thickness of the air space and of the second glazing II are indicated equal to 0 by convention.
- Double glazing 5 and 6 include two laminated glazing consisting of a sheet of glass 2.1 mm thick, glued to a sheet of glass 1.6 mm thick via a layer of PVB 0.76 mm d 'thickness.
- the minimum transmission in dB of GSM waves between 0.7 and 28 GHz is measured through all these glazing.
- the transmission of GSM waves is the same for two panes which differ only in that the air space 0.1 mm thick is at atmospheric pressure for one and under vacuum for the other.
- the transmission of GSM waves is better through glazing based on glass with a lower Fe content (Glazing No. 1, respectively 3, respectively 5) than through the corresponding glazing, differing from them only by the composition of the glass (higher Fe content) (Glazing 2, respectively 4, respectively 6).
- the minimum transmissions in dB of GSM waves at 2.6, 3.8, 6 and 28 GHz through glazing 1, 3 and 5 above are recorded in the table below. [Table 4]
- glazing 1 and 3 show that a double glazing with a thin air gap under vacuum (glazing 3) transmits GSM waves almost identically as a monolithic glazing of the same glass as this double glazing and of identical thickness (glazing 1).
- Glazing No. 5 shows that it is possible, with a glass with a relatively low Fe content, to design a double glazing with two laminated glazing, the high frequency transmission of which, in the context of the invention, is greater than - 5 dB.
