Soundproof Plasterboard 15mm

Soundproof or acoustic plasterboard is used in a variety of soundproofing systems or can be used on its own. It differs from traditional plasterboard by having a higher mass. Higher mass means better soundproofing, so this product assists in the reduction of airborne noise like talking or TV noise.

Skim or tape

Tape & joint or skim

Our acoustic plasterboards have a tapered edge. This means you’re able to tape and joint as a speedier way to finish your project. Our boards are also ready for traditional skimming.

Cost-effective Mass

Adding mass is a key aspect of soundproofing but high mass products can get costly. Soundproof plasterboard is one of the cheapest forms of mass you can add to a soundproofing system.

Fast delivery

We can deliver soundproof plasterboard in 2-5 working days. Call our team for more details. Be prepared as the product ships on a pallet.

Soundproof plasterboard works best as part of a system like our MuteClip systems, or when combined with other materials.

If you’re looking for an easy-to-install system perhaps look at our MuteBoard products. They are acoustic plasterboards bolstered with other soundproofing materials and can be applied directly to the wall.

Another option is to include acoustic mineral wool in between cavities if the space you’re treating is a stud frame or ceiling joists.

Yes, many soundproofing systems make use of soundproof plasterboard on ceilings.

No, the boards would crack and break. We recommend using an acoustic underlay if you are interested in soundproofing a floor.

The blue facing of Acoustic Plasterboard can be skimmed straight onto without any additional lining paper. Remember to use scrim tape on all joins to make sure the plastering layer bonds successfully.

All rolled carpets can be pulled directly over MuteMat® 3 without any need for an over boarding, Carpet Gripper Strips will need to be fit around the perimeter of each room to raise the gripper rods to a more suited height.

The blue paper finish will want to be facing into the room; if using a tapered edge, it will be the tapered edge facing into the room.

  1. Make sure that the surface you are applying to is flat to avoid any joints unsuccessfully matching up. 
  2. When fixing Acoustic Plasterboard you need heavy-duty fixings of 18 per board and remember to leave a 2-5mm gap from the adjacent surfaces.
  3. Fix with tapered edge vertically.
  4. Fill all gaps, including the abutting of all joints and around the perimeter. The aim is 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.
  5. 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.
