Acoustic Plasterboard:

The density of this board is higher than that of standard drywall boards. As a result it will reduce noise transmission such as speech and music to improve insulation against sound. It is most often used with additional mineral wool and resilient bars to reduce sound vibration.

Moisture resistance plasterboard:

Used for bathroom, kitchens and other areas with high humidity to prevent damp penetrating the board.

Impact resistant Plasterboard:

This board has a very dense core and is lined with heavy duty paper to resit damage caused by impact or vibrations.
