Cost Effective Soundproofing for Walls

There are many soundproofing solutions for walls; however, not all are cost effective. Have a look at the Gyplyner system below, it’s quite a robust and cost-effective solution as it reduces the build-up of an independent wall solution, whilst maintaining good soundproofing properties, this system would lose you about 52mm with skimmed 15mm sound board, or 62mm with two layers of 12.5mm soundboard. It’s a good off the shelf solution as the GL1 profile is held in stock by most large building merchants and the brackets a just screwed to the wall and bent round, then screwed to the GL1 profile, which makes it quite quick and easy to install – as per the detail below.


Sometimes a single skin of lightweight blocks (such as thermalite) may have been used in the party wall construction which is a poor soundproof wall construction due to its lack of mass. This type of masonry may be only 500kg/m3 (50kg/m2), masonry should be around 1850kg/m3 (185kg/m2) which can easily lead to sound test failure if used in the inner envelope construction and or party walls.

It’s worth remembering for sound to conduct through a wall, it has to actually move or vibrate the party wall ever so slightly. A heavy mass wall is always much harder to move than a lighter wall. It is very important to note that a heavy wall will still vibrate, just not as easily as the lighter one.

If you understand the above elements that make up party wall and floor design and construction, you’ll have a more educated eye for the acoustic design on your dwelling,  for instance, the  4 main elements of soundproofing construction are:

  1. Adding mass in your party walls
  2. Decoupling of materials within party walls
  3. Noise absorption within party walls
  4. Noise damping in party walls

In a nutshell soundproofing is the art of trying to prevent vibrations crossing party walls and floor partitions.
