Our Basic Brick Wall Soundproofing System is an excellent choice for reducing the transmission of TV noise and airborne conversations through separating walls. With its simple installation process and slim profile, this system offers an effective solution for upgrading the sound insulation of party and separating walls in various residential properties.

We have developed a user-friendly system that requires minimal DIY experience to install. It involves the application of a layer of M20 Soundproofing Mat and two layers of 15mm Acoustic Plasterboard. This combination of materials significantly enhances the sound insulation properties of your wall, effectively preventing noise leakage. Despite its impressive soundproofing capabilities, the system maintains a relatively thin profile, with a total thickness of 50mm. This ensures that the upgrade doesn't compromise the available space or aesthetics of your room.



Installation Guide

  1. Ensure the wall you are mounting this system to is sound and free from defects is clean, dry, and free from dust, grease, and any other contaminants. Remove all skirting, covings, wallpaper and any loose paint.  If the wall has sockets and light switches these will also need to be removed and temporarily isolated by a trained electrician.
  2. Starting in the bottom left corner apply Advanced Acoustics Contact Adhesive to the mounting surface ensuring you cover an area slightly larger than the size of the M20 Soundproofing Panel.
  3. Apply adhesive to one side of the M20 Panel, completely coating it. You can apply adhesive to any side.
  4. As soon as the adhesive is applied the adhesive will be cured and the panel can be offered in place. Ensure you leave a 5mm gap between the M20 panel and the floor and the same size gap between the M20 panel and the adjoining wall.
  5. Repeat this process until a full row has been fitted. Ensure there are no gaps between the M20 Panels.  If the final M20 Panel has to be trimmed remember to allow for a 5mm gap between the M20 Panel and the adjoining wall.  The M20 Panel can be cut to size with a utility knife and straight edge. This will help users achieve clean and accurate cuts.
  6. If there are sockets or switches you will need to cut a hole out of the M20 Panel in the correct location.
  7. You can now fit the second row, staggering the joints from the first row if possible. This will also help to minimise waste.
  8. Repeat the process until you come to the final row.
  9. The M20 Panels may need to be trimmed to size to allow fitment of the final row. Remember to allow for a 5mm gap between the M20 Panel and the ceiling.
  10. You now need to seal the 5mm gap you have left around the perimeter of the wall using AC95 Acoustic Sealant. Additionally if there are any gaps between the M20 Panels use the same product to fill these gaps. Use a caulking gun for precise and smooth the sealant over for a professional finish.
  11. Next run the PVC Jointing Tape across all the joints to create a complete seal.
  12. You are now ready to install the first layer of 15mm Acoustic Plasterboard. Depending on the height of the wall you may need to trim the plasterboard to the correct size.  Remember to maintain that 5mm gap at the bottom and the top. 
  13. If there are any sockets or switches you will need to cut a hole out in the plasterboard in the correct location.
  14. Starting from the left hand side apply adhesive to the previously mounted M20 Panels ensuring you cover an area slightly larger than the sheet of plasterboard.
  15. Apply adhesive to the back of the plasterboard sheet, completely coating it. Offer it into place leaving the 5mm gap between the plasterboard sheet and the adjoining wall.
  16. Repeat this process until the wall is completely covered in plasterboard. Do not leave gaps between the sheets of plasterboard.
  17. For the final section the sheet of plasterboard may need to be trimmed to the correct width remembering to allow for a 5mm gap between the plasterboard sheet and adjoining wall.
  18. You now, once again, need to seal the gap between the plasterboard and the adjoining surfaces. Additionally seal any gaps that have been left in the sheets of plasterboard.
  19. You are now ready to fit the final layer of 15mm Acoustic Plasterboard. Repeating the same process, apply adhesive to the plasterboard already mounted on the wall.  Cover an area slightly larger than the plasterboard sheet to be mounted.  Apply adhesive to the back of the plasterboard sheet to be fitted, completely coating it.
  20. Remember to maintain the 5mm gap. Stagger the joints from the first layer by using the off-cut left over from the first layer of plasterboard.
  21. If there are any sockets or switches you will need to cut a hole out in the plasterboard in the correct location.
  22. Repeat the process until the whole wall is covered.
  23. For one final time apply AC95 Acoustic Sealant in the 5mm gap you have left around the perimeter of the room.
  24. The wall is now ready to be skimmed or tape and jointed.
  25. Reinstate any skirting and covings.
  26. Have a qualified electrician reinstate any sockets and switches.
