Abstract: The invention relates to a glazing (1) with improved vibro-acoustic damping properties, that comprises at least one glass sheet (10) and at least one vibro-acoustic damping profile (2) connected by at least one face thereof to the glass sheet and including at least one member of a damping material (20) having a loss factor at least equal to 0.4 and a Young modulus lower than 200 MPa at 20°C for frequencies lower than 5000 Hz. The profile (2) also includes a weighing member (3) having a lineic mass higher than 0.05 kg/m and connected to the member made of a damping material (20), the member made of a damping material being provided between the glass sheet and the weighing member, and no other device except the glazing is associated with the profile.

Abstract: A glazing unit having improved vibroacoustic damping properties, including: at least one glass sheet; at least one vibroacoustic damping strip, the strip including at least one element made of damping material and the strip being fastened to one of the faces of the glass sheet. The face of the strip facing the glass sheet has a surface area in contact with the glass sheet which is strictly inferior to the surface area of the face of the strip facing the glass sheet. The glazing unit makes it possible to damp noise and vibrations while taking up little space.

Abstract: A glazing unit with an improved vibroacoustic damping property including at least one sheet of glass and at least one vibroacoustic damping strip that is attached to at least one of the faces of the glass sheet and that includes at least one component made of damping material having a loss factor greater than 0.2. The strip is not joined to any other device on the opposite side from the glass sheet and the component made of damping material has a Young's modulus greater than 800 MPa, at 20° C., for a particular frequency corresponding to the critical frequency of the glazing unit to within plus or minus 30%.
