What’s the difference between acoustic glass and laminated glass?
Thin panes of glass can only absorb a small amount of sound vibrations before allowing the rest to travel through, so acoustic grade glass has to be laminated with an insulating interlayer to absorb and dampen much more of the noise. This means that all acoustic glass is a type of laminated glass. The difference is that not all laminated glass is acoustic, just as it’s a form of toughened glass, but not all toughened glass is laminated. For laminated glass to achieve acoustic grading, it needs thicker layers of glass or asymmetrical thicknesses, and an insulating material for the interlayer. Consider acoustic glass to be an upgrade from standard laminated glass. The ‘sandwich’ method of construction is more or less the same, and both types visually look like any standard pane of glass, but laminated glass isn’t as effective at reducing noise unless the sound insulation is optimised.
