The Knauf 19mm Tapered Edge Acoustic Plank Plasterboard is a high-performance building material designed for contractors and DIYers focused on superior sound insulation in residential and commercial spaces. By leveraging its high-density gypsum core, this board significantly reduces airborne sound transmission, offering a more robust alternative to standard drywall. While its increased mass and thickness provide excellent acoustic control and rigidity, users should account for the heavier weight during installation compared to thinner, standard plasterboards.

This is a standard acoustic plasterboard. If used in wet areas, it must be protected with a suitable waterproof tanking system or moisture-resistant finish.
This product is supplied as a 24-pack.
The dense gypsum core provides inherent fire protection, though you should consult local building regulations for specific fire-rating requirements for your project.
While it can be used in 'dot and dab' systems, ensure the wall is dry and prepared correctly to receive the adhesive.
Yes, the increased mass of the 19mm board significantly improves the transmission loss of airborne sound.
Ensure the underlying frame is rigid and that the boards are screwed at proper intervals. Use paper tape rather than mesh for superior crack resistance.
Ensure you are using screws rated for high-density acoustic board and check that the screwdriver bit is not worn out.
For installation, ensure the stud work or floor joists are level to prevent bowing, as the boards are rigid and less forgiving than thinner variants. Use high-quality drywall screws designed for denser boards to ensure secure attachment. Always store the planks flat in a dry environment, protected from moisture, to prevent warping of the gypsum core. When cutting to size, use a sharp utility knife to score the paper layer before snapping the core, or utilize a fine-toothed saw for complex cuts. For jointing, apply a high-quality jointing compound into the tapered recesses and finish with professional paper or mesh jointing tape.
