Due to the vacuum there is little mutual contact between the 2 glass sheets. This not only creates a very good insulation value, but also very good sound reduction.
Normally, very thick glass is needed to achieve sound reduction with insulating glass. This is not the case with vacuum glass. Even in the thinnest version, a dB value of dB=36 is already reached.
This dB value can rise to dB=41 with thicker vacuum glass or with the laminated version.
In short: noise reduction in combination with a thin construction? This is only possible with vacuum glass with the exceptionally good values of BENGglas.
