Specialist Acoustic Plasterboard for Part E Building Regulations Compliance

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. We split Acoustic Plasterboard in half here, and this is often 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.

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.

Installation Guide

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.
