Multiple glazing with thermal and acoustic insulation

摘要

A multiple glazing element including at least one pane of laminated glass of two glass sheets that each have a thickness between 1.5 and 2.5 mm, and a single thickness glass pane having a thickness between 3 and 5 mm. The weight of the glazing element is at least 30% less than the weight of an insulating glazing element that includes at least two single thickness glass sheets separated by a layer of gas having the same thickness as that of the multiple glazing element, with a difference of sound reduction index between the multiple glazing element and the insulating glazing element not exceeding 3 dB.
