How to control the noise level?

To reduce the noise level it is important:
To use glasses with different widths in order to reduce the vibrations, for example one 4mm and one 5mm
To increase the width of the glass, for example 5mm or 6mm in exchange for the 4mm one, that have bigger mass
To exchange one of the glasses with a laminated one – manufactured by connecting two or more float glasses with a middle plastic layer
To increase the air space between the glasses
To use an insulating glass unit with two chambers – triple insulating glass unit
The noise insulation is not improved by using argon gas. In buildings where noise insulation is important – railroad stations, airports, etc, we use laminated glasses with special resin as a middle layer.
