Phonestar Acoustic board on its own has been certified to reduce Airborne Sound by a very high 36db ( DW) When the acoustic plasterboard is then added to a wall, floor or ceiling structure, the overall Airborne Sound Insulation result of the complete structure will be much higher.

The Phonestar boards reduces Impact Sound by a very significant 21dB  when laid on the industry standard concrete test floor. The overall impact sound insulation result of the complete floor and ceiling structure can also be tested and this laboratory result in Decibels is denoted by Ln,w. Please note that when comparing Impact Sound Insulation results of the complete floor structure, the lower the result the better the reduction in impact sound.

Cutting & Sealing Boards

The Db boards can be cut with most hand tools, be careful to keep board flat when cutting otherwise you will lose the sand. If this does happen keep a dustpan and brush to sweep it up and refill the board.

Sealing Board after Cutting

Use the specially designed tape to re seal the boards after cutting. Using a standard gaffer tape will not work as it will not get a perfect seal.

Installing the Db boards

Always stagger the joins when installing the Db boards
