Known for its ability to reduce sound transmission, acoustic plasterboard enhances comfort by blocking and absorbing sound waves. Whether you are constructing a stud wall or upgrading an existing space, acoustic plasterboard provides a practical and effective way to improve acoustic performance.

What is Acoustic Plasterboard?

Acoustic plasterboard, often referred to as soundproof boards or sound board plasterboard, is denser than standard plasterboard. It is specifically designed to enhance sound insulation and reduce noise transfer between rooms. Available in sizes such as 2400mm x 1200mm and thicknesses like 12.5mm acoustic plasterboard and 15mm acoustic plasterboard, this material is suitable for a wide range of applications.

Benefits of Acoustic Plasterboard

  3. Fix the Plasterboard – Secure the acoustic plasterboard directly to the stud wall or ceiling using appropriate screws.

  4. Seal Gaps – Use acoustic sealant to seal any gaps, preventing sound from travelling through.

  5. Finishing – Apply plaster or jointing compound and sand the surface for a smooth finish.

Key Considerations

  • Type of Plasterboard – Choose between 12.5mm and 15mm acoustic plasterboards depending on the level of sound insulation required.

  • Wall or Ceiling Application – Ensure the plasterboard is suitable for the specific application (walls, ceilings, or partitions).
