19mm Knauf Plank Plasterboard - Square Edge - 2400mm x 600mm

19mm Knauf Plank Plasterboard - Square Edge is a high‑density gypsum board designed to enhance the acoustic performance of internal partitions and separating walls. Longer and heavier than standard plasterboard, it is typically used as part of multi‑layer systems where improved sound insulation is required, particularly in residential, commercial and multi‑occupancy buildings. Knauf Plank is manufactured as a 19 mm thick, high‑mass board, which helps reduce sound transmission by adding density to the wall build‑up. Its extended length makes it ideal as the first layer in acoustic systems, providing a solid base for additional boards while minimising the number of horizontal joints.

CHARACTERISTICS

• High‑density 19 mm core: Adds mass to wall systems, improving acoustic performance.
• Extended board length: Reduces horizontal joints and speeds up installation.
• Ideal first‑layer board: Forms the foundation of many Knauf acoustic wall and partition systems.
• Smooth paper face: Suitable for taping, jointing and finishing to a high standard.
• Compatible with metal and timber stud systems: Works within a wide range of internal wall constructions.
• Fire rating: A2-s1, d0 (B).

APPLICATION

• Acoustic partitions in homes, apartments and hotels
