    10.8mm Acoustic Laminate

    Two layers of glass (6.4mm + 4.4mm) bonded with a specialised acoustic PVB interlayer. The interlayer acts as a dampener — absorbing vibration energy and converting it to heat before it can pass through. Combined with a 150mm air gap, this achieves recording-studio silence.

    Acoustic PVB Interlayer

    The specialised Polyvinyl Butyral resin between the glass layers acts as a vibration dampener — absorbing sound energy and converting it to heat. This eliminates the "coincidence dip" where standard glass becomes acoustically transparent.
