Patent ID: 7931117

Claim:
A glazing unit comprising: at least one glass sheet; and at least one vibro-acoustic damping strip, which is fastened onto at least one of faces of the glass sheet and that includes at least one element made of damping material having a loss factor of at least 0.4, wherein the strip is joined to no other device on a face of the strip that is on an opposite side from a face of the strip that is in contact with the glass sheet and the strip also includes at least one weighting element that has a linear mass of greater than 0.05 kg/m and is fastened onto the element made of damping material, the linear mass corresponding to a ratio of a mass of the weighting element to a longer length of the weighting element of a face of the weighting element in contact with the element made of damping material, the element made of damping material being inserted between the glass sheet and the weighting element and having a Young's modulus of less than 200 MPa at 20° C. for frequencies below 5000 Hz, the weighting element being joined only to a face of the element made of damping material that is on an opposite side from a face of the element made of damping material in contact with the glass sheet.
