- the glass sheet 1 of the glazing is intended to be turned towards the outside of the vehicle while the glass sheet 2 is intended to be turned towards the inside of the vehicle.
- the glass sheet 1 is preferably thicker than the glass sheet 2 so that the glazing allows better protection against external attacks (inclement weather, projection of chippings, etc.). Indeed, the thicker the glass, the more mechanically resistant it is. However, the thicker the glass, the heavier it is. We must therefore find a compromise between the mechanical strength and the weight of the glazing.
- the thickness of the glass sheet 1 is for example between 0.5 mm and 2.6 mm, preferably between 1.4 and 2.0 mm and the thickness of the glass sheet 2 is for example between 0.5 mm and 1, 6 mm, preferably between 1, 1 and 1.5 mm.

The rate and the nature of the plasticizer and the degree of acetalization of the polyvinyl butyral make it possible to play in a known manner on the rigidity of a component based on polyvinyl butyral and plasticizer.
- the spacer also comprises two layers 4, 5, said outer layers, between which is inserted the layer 3.
- the outer layers 4, 5 are preferably standard PVB.
- the layer 3 is less rigid than the outer layers 4, 5 in order to vibrate properly to ensure the desired acoustic damping.
- the interlayer may comprise at least two viscoelastic plastic layers with vibro-acoustic damping properties, surrounded or not by standard PVB layers.
- the acoustic characteristics of the interlayer are determined by measuring the mechanical impedance (MIM) at 20 ° C according to ISO 16940 of a laminated glass pane with a surface area of 25 mm x 300 mm composed of two sheets of glass. thickness 2.1 mm (and not 4 mm as recommended in ISO 16940) each between which is incorporated a spacer according to the invention, that is to say a spacer comprising at least one viscoelastic plastic layer with properties vibro-acoustic damping.

- the resonant frequency f 2 is between 800 Hz and 900 Hz, which makes it possible to have improved acoustic performances by degrading less the level of weakening of the laminated glazing before the critical frequency. Even more preferably, the resonant frequency f 2 is between 800 Hz and 850 Hz, which makes it possible to have performances acoustics further improved by further degrading the level of weakening of the laminated glazing before the critical frequency.
- the loss factor ⁇ 2 is greater than 0.30, which makes it possible to have improved acoustic performance by improving the acoustic damping.
- the measurement of the mechanical impedance (MIM) is carried out at least 1 month after assembly of the laminated glazing bar, the laminated glazing bar having itself been assembled at least 1 month after the manufacture of the interlayer. This makes it possible to be sure that the interlayer and the laminated glazing have reached stable states and thus to determine reliable values.
- Figure 1 shows a curve of sound insulation as a function of frequency, measured on three windshields.
- the acoustic insulation of a glazing unit accounts for the acoustic performance that can be observed on a vehicle equipped with said glazing.

- the acoustic insulation curve (represented by squares) of the second windshield shows a behavior similar to that of the first windshield until around 5000 Hz, but a hollow shifted towards the high frequencies, around 8000 Hz. This offset of the hollow is very annoying because it implies that this windshield passes airborne sounds at high frequencies that are troublesome for the human ear.
- a third windshield (18-14 invention) comprises:
- interlayer comprising two outer layers made of standard PVB and a viscoelastic plastic core layer with vibroacoustic damping properties, the interlayer having a resonance frequency f 2 of 800 Hz ( ⁇ 15 Hz) and a loss factor ⁇ 2 equal to 0.30 ( ⁇ 0.03).

- the thickness of these outer layers 4, 5 is for example adapted in known manner, for example by the patent application FR 09 52567.
- the interlayer is tinted in the mass at least on part of its surface.
- tinted only at the top of a windshield, it helps protect the driver of a vehicle from dazzle him in the light of the sun.
- tinted over its entire surface it can allow respect for the privacy of people inside a vehicle.
- hue When the hue is weak, it simply has an aesthetic effect. In case of light transmission too low compared to existing standards for the windshield or the front side windows, it can be used in a rear side window, in a rear window or in a quarter window of a motor vehicle.
