Universally recognised throughout the world of soundproofing, commonly used as part of an acoustic system, or combined with additional acoustic materials such as our MuteClip®.

You will have come across Acoustic Plasterboard many times in soundproofing, maybe you have seen it in one of our guides, or a local installer is looking at it as a solution to your neighbour noise, or seen it on a specification for a housing or office refurbishment. It is a truly universal product. Half size plasterboards are sometimes necessary for small projects where tight areas that offer limited mobility for full-size Acoustic Plasterboard benefits from the half size.

Soundproof Plasterboard has a higher mass than standard Plasterboard, and it is this mass that assists in the reduction of airborne sound transferring from room-to-room by blocking the flow of sound energy. To achieve the best possible result in soundproofing, you will need to incorporate Acoustic Plasterboard into our acoustic systems, and you will find these in our 'Systems' tab above in all of our ceiling and wall soundproofing systems. Each offers methods of increasing the soundproofing performance by combining them alongside our MuteClip®, or as the front face of our MuteBoard® series, or as an option for the direct install to stud frames where available space is at it's most premium.


  • 1200mm x 1200mm x 15mm (1.44m2)
  • Blue-faced Acoustic Plasterboard.
  • Increased density over standard Plasterboard for best acoustic performance.
  • Featured in our MuteClip® Systems for walls and ceilings.
  • Tapered Edge.
  • Apply plaster skim directly over the top.

Whether you find that random conversation or light household use enters your home, or you are looking to put together a solution for a workplace environment that is effective and easy to install, Acoustic Plasterboard is essential.



This product contains a high level of mass, so if there any structural concerns you will want to consult a Structural Engineer to discuss your requirements.

*Our Typical Performance Results and Noise Reduction Guidance are provided to indicate the results that have been achieved in previous tests but are not guaranteed to a specific site as multiple factors can affect this, you can view their variants on our 'Featured Systems' tab.

We endeavour to display the most up to date testing and assist in managing your expectations through each stage of the process so that the choice we make is the right one.

The world of soundproofing and general construction presents an uncertain journey for those arriving fresh to the subject, there maybe terminology or use of acoustic testing figures that could appear confusing, and even if you are at a professional level, it is good to brush up to make sure you are making the right choice. We want to help you come to the right decision, so whether this is through the use of our guides or talking to a member of our team - we are here to help!

How to Soundproof a Wall or Ceiling


A combination of the following will always result in a much improved acoustic performance.

  • Mass: the addition of more substantial materials to reduce sound energy, for example, added layers combined with soundproof Plasterboard.
  • Separation: breaking contact with the surface or surfaces through the use of acoustic isolation clips or stud framing.
  • Damping: the reduction of vibration through the use of flexible, damping materials such as Tecsound.


To create a soundproofing system that can reduce an extensive range of sounds and noises, you will need to combine all of the properties above. By separating the mass from the structure and suspending it away, you are breaking contact with the construction and creating an air gap, which is both essential in the better reduction of sound, especially if they are ones you can hear clear as day. Low-frequency noises and vibration are not just created in areas with amplified music or machinery, but can originate from televisions attached to the wall, or the low-tone of a male voice and even closing a door - these noises often travel greater distances than you'd think, and will also on occasion, lead to Flanking Transmission. We recognise the subjective nature of sound and how we react to each one, and that is why we offer so many variances in our systems.

We understand that it is not always possible to incorporate significant losses of space with say, the introduction of a stud frame, so we provide different variances to suit what performance you need, your budget and thickness.

  • You will want to make sure that the surface you are applying to is flat to avoid any joints unsuccessfully matching up. 
  • When affixing Acoustic Plasterboard you will want to use heavy duty fixings of 9 per board, evenly spaced and remember to leave a 2-5mm gap from the adjacent surfaces.
  • Fix with tapered edge vertically
  • Fill all gaps, including the abutting of all joints and around the perimeter. The aim to make sure the surface is as airtight as possible as you are trying to reduce airflow that airborne noise transfers through, even the smallest of gaps.
  • Use a scrim tape on joins to provide a strong bond for skim plastering; it is essential to note that you require no additional lining paper for skimming, it is ready to go.

The provision of half-size acoustic plasterboard is for properties that present difficulties in moving large materials through as they are easier to manoeuvre than full-size acoustic plasterboard but will give a slight increase in breaks of the acoustic system. We also provide these when low quantities of full-size acoustic plasterboard are not available for delivery as our minimum order quantity is 20.

Yes it can be, it’s blue paper lining will help the skim layer adhere to it with no issue, scrim tape should be used on all joins so that the acoustic sealant does not hinder the plaster’s grab.

Rooms that require sound proofing with a real premium for space that would only allow for the thickness of a single layer of acoustic plasterboard will provide a slight increase over standard plasterboard. But, in most cases, we would recommend combining with other sound insulation materials such as our MuteClip® System, or our stock materials that incorporate acoustic plasterboard like our MuteBoard® 2, MuteBoard® 3 and MuteBoard® 4.

We do not recommend the use of Acoustic Plasterboard for floor soundproofing, and this is because there is potential for the board to crack as well as not lending to accommodating any deviation of joist levels.

The blue paper lining always wants to be facing into the room, and this is so that it can be skimmed when completed - the brown facing on the return cannot be decorated on to.
