Soundproofing between walls

Soundproofing Between Walls

There are many reasons why we want Soundproofing Between Walls. Let’s have a look at a few of these: Privacy, Noise pollution, etc. Importantly one must first establish what type of sound we need to address. As a result, both Airbourne and impact noise must be considered to solve the problem effectively.

Many modern-day apartments are built with cost savings in mind. As a result, some of these units seem to have noise pollution between the walls. In most cases, fitting an appropriately insulated internal Drywall Partitioning wall can solve this problem. 

Types of Noise

Airborne noise: Typically from traffic people talking and radios and TVs etc. Airborne sound is the most common problem. Indeed Airborne noise is all around us in everyday living.

Impact noise: Regarded as one of the most challenging noise problems to solve. In general impact, the sound is hammering, banging, stomping, etc.)


We Can Install An Insulated Drywall To Reduce Noise Pollution

Benefits of Soundproofing Between Walls

As we are all aware, Noise pollution is stressful. Clearly, we have even labelled this problem as pollution. Regarded as intrusive noise. People living near airports have sleepless nights as planes fly overhead. One of the most common questions we encounter is soundproofing between walls, followed by Soundproofing between floors. Many homeowners will buy their first apartment with the hope of a healthy, happy life. Only to discover that evening time in the complex is party time—a nightmare in the making causing friction between neighbours.

  • Privacy in the office or boardroom
  • Privacy at home
  • Increase productivity in the workplace
  • Reduce stress; noise triggers anxiety, one of the major causes of many health problems, including heart disease.
  • Silence is golden

Noisy Neighbors: Soundproof Between Walls

As homes in complexes are relatively close to each other, noise pollution is one of the common issues. More often encountered in simplexes and townhouses attached to a respective wall. Making home life a bit of a nightmare, especially if your neighbours don’t need the sleep you need. As a result, soundproofing between walls is often the only way forward. However, if this not installed correctly, it can be a waste of money.

Office space, as well as boardrooms, doctor surgeries, etc., are also in need of privacy.

Soundproofing Walls

Ideally one needs to fit Cavitybatt insulation or even a higher density insulation material like Energylite 475. Preferably, the wall directly opposite the noise source must be insulated.

However, Sound Proofing walls is not always the only solution, as noise pollution is also airborne. More often than not, there is a combination of roof space as well as windows and wall.

Therefore, covering all aspects of the problem must be addressed to solve the problem.


Therefore installing the insulation starts with the drywall structure framework being fitted directly against the wall. Secondly, make sure that the structure allows space for insulation as well as a cavity space. It is essential to leave a cavity space between the insulation and the new drywall. The Drywall must not be less than 12mm thick.

  1. Fit drywall grid
  2. Leave a cavity space of at least 25 to 50mm
  3. Install Energylite 475 at least 75mm thick
  4. Finally, complete drywall and skim

Install Heavy Curtains

Installing heavy acoustic curtains will be beneficial. Ideally, the curtains should be long enough to fanfold them. As a result, the curtains will act as an acoustic barrier reducing noise pollution via the window.

Install Acoustic Roof Insulation

When installing the Roof Insulation remember, not all roof insulation materials have got good acoustic properties. In these applications, it is imperative that insulation with a high NRC (Noise Reduction Coefficient.)

As a result, Ecose Insulation or the Aerolite Glasswool are the best choices for these applications. The 135mm Ecose Insulation has one of the highest NRC values at 1.13, followed by 135mm Aerolite with an NRC of 1.05.

Sound absorbing panels are also ideal when all the internal work has been completed.

Cost Of Soundproofing Walls

There are a number of factors to take into account when soundproofing walls. In some cases, a single Drywall partitioning panel is ideal. However, in most cases an insulated drywall system is by far the best option.

The importance of adding soundproofing insulation against the wall goes without saying. Adding good quality acoustic insulation is the best soundproofing walls option. However, the acoustic insulation does not need to cost an arm and a leg.

In many cases, low-density insulation products like Think Pink Aerolite will kill all sound between walls. The reality is that we install the 135mm Aerolite insulation in night clubs and pups to kill noise leaving the building via the roof.
