Soundproofing between Floors

Soundproofing Between Floors

Noise pollution is one of the most common complaints from city people, and it’s only getting worse. It’s well known that noise pollution can harm our health and well-being in the short and long term. Soundproofing Between floors is one of the best ways to reduce noise pollution in your home or office. Our products are designed to block out Sound from above and below, so you can enjoy quiet whenever you need it.

Why is Soundproofing Between Floors Needed

Are you looking for a way to reduce noise in your home? The importance of Soundproofing Between Wooden Floors is the perfect solution for you. Our products will help to reduce the amount of noise that travels through your floorboards. Our products are easy to install, and they’ll make a big difference in the amount of noise you hear. You’ll be able to enjoy quiet in your home, without worrying about Sound travelling through the floors. Contact us if you have a problem because we have a solution.

When one looks at the beautiful Cape architecture, we don’t think about noise. However, they built many of these homes in the 1970s. Therefore some of these homes have wooden flooring. We all remember the wood floors at our grandparent’s houses and how noisy they were.

In double, volume homes, the noise from above can be frustrating. However, some of these majestic buildings are subdivided in some cases. Ok, for the homeowners above but a real-life nightmare for the people below.

When the people above talk softly, this Sound travels straight into the floor space. In fact, in the evening, when the homeowners above you are enjoying the Tv or music, you have no option but to listen.

The Sound from above and below will have no problem travelling through the wood floors. It is called airborne noise. As a result, this is not pleasant for either homeowner.

What is Airborne Sound?

Often referred to as Ambient Sounds.

  • These are sounds caused by the ringing of phones talking and radios and TVs.
  • As a result, they are transmitted through the air, mainly through wood floors and open ceilings in double-storey homes.
  • We are blocking all cavity spaces as well as installing sound Insulation. Sound-absorbing Insulation has proven to be the best method for these kinds of noise.

Impact Sounds

  • These sounds are direct. Especially with wooden floors and high heel shoes, they are making direct contact with the floorboards. Even general walking or running above will be transferred through the floor and ceiling above.
  • Impact sounds are vibrations in the floor, roof, and ceiling construction. As these components are attached, one can only describe the noise as a doctor’s stethoscope. Therefore Sound is transferred between objects.

As a result, these applications are more difficult. More building work will be needed rather than lifting floors and installing Insulation. Installing Sound or acoustic Insulation will not get rid of this problem.

Soundproofing between floors needs to be accompanied by removing the ceiling and installing a Floating Ceiling or rhino board ceiling application as described below. However, it is possible, and it is a little more expensive. Contact us here for more info.

Best Option for Soundproofing Between Floors

As mentioned above, the two major noise elements are Airbourne Noise and Impact. Firstly we must remove the ceiling. Once completed, the process is as follows. Importantly this is not a simple fix. Fit the Insulation correctly with no air gaps.

When Soundproofing between floors, ensure that someone is on hand to ensure no air gaps. Leaving many workers on their own can be expensive in the long run.

Soundproofing Wooden Floors

Wooden floors are a popular choice for homes, but they can be very noisy. Impact noise from people walking or running upstairs can be heard in the lower part of the home. The noise can be incredibly disruptive and frustrating, especially if you’re trying to relax or sleep. Soundproofing wooden floors is a great way to reduce noise and create a more peaceful environment in your home. Our soundproofing products are easy to install and will dramatically reduce the amount of noise that travels between floors.

Soundproof Floor Insulation Products

The best Acoustic Insulation available is also the most affordable. Most Soundproofing Insulation products are excessively expensive; however, we have Soundproofing Insulation products that are very affordable.

In most applications, a single layer of either of these insulation products will work perfectly. However, for excessive noise, we would recommend installing two layers.

Installing Floor Insulation

Cut the acoustic Insulation at least 50mm wider than the floor beams. We will push the Insulation into the cavity space between the beams. The floor trusses will usually be around 350 to 420mm apart.

Installing two layers of Insulation will be great. Installing products like the Knauf Ecose Insulation or Think Pink Aerolite is perfect for these applications. The NRC 1.13 (noise reduction coefficient) is excellent. As a result, we substantially reduced the Airbourne sound in the process. Check out our Price ListPrice Lists page for prices on these soundproofing products.

Installing the ceiling

The next step to get the best out of the Soundproofing between floors application is Significant.

Firstly, install the ceiling below the floor after two acoustic insulation layers are installed. The ceiling must be 12mm Rhino board type. Seal all joints and any gaps against the wall with an appropriate cavity sealer. Importantly seal all air gaps. Once completed, the next part of the application will start.

We are starting with a grid system fitted below the first ceiling. Importantly, no part of the grid must contact the ceiling space above. IMPORTANT!! The ceiling grid should be at least 75mm below the first ceiling.

The air gap is essential; however, the most important is that wires cannot be attached to the ceiling and floor above. Some installers will fit drywall metal grid sections with cables for support in the centre.

It will be a waste of all the above work as sound transference will remain a factor. A mistake of nature will still allow for the Airbourne sound to be improved. However, the Impact sounds will always be a factor—apologies for pushing this point. Having been in the industry for many years, we have seen this mistake happen many times.

After fitting the grid system, the final Ceiling Board is, therefore, fitted. The recommendation would be the Rhino board type 12mm thick. Plater and finish off. The home will be far more comfortable.

How To Reduce Noise Between Floors

Noise from upstairs neighbours or other house areas can be incredibly frustrating and distracting.

Agitate: Concentrating or getting a good night’s sleep can be difficult when you’re constantly disturbed by the noise from above or around you.

Solution: Installing Insulation is an effective way to reduce noise levels and create a more peaceful environment in your home. We offer two types of Insulation designed to minimise sound transmission between floors – the Knauf Ecose and Aerolite.

There are many types of Insulation to reduce noise between floors. However, this is not a simple application that we can change if we make the wrong choice. It is for this reason that we recommend installing Insulation that works. Also, it is important to ensure that all gaps are closed off.

We will install between one and two layers of Insulation like the Knauf Ecose and the Aerolite. Not only do these two insulation products work well for Soundproofing between floors, but they are also non-combustible. And it is important to install Insulation that will not burn between the wooden floors.

How Insulation Dampens Sound Between Floors

Fitting the correct insulation between the wooden floors will dampen the sound between floors. The insulation with a high NRC will absorb the sound, reducing the impact of the noise from above. Another important addition is to add Sondor rubber strips to the top of all wooden beams before the floor is refitted. The Sondor rubber reduces the Impact noise substantially.

Best Insulation for Soundproofing Between Floors

The best Insulation for Soundproofing Between floors must have a high NRC. Importantly the Insulation must have a high fire rating because wooden floors are combustible. For this reason, we recommend installing Non-combustible Insulation between floors.


  • Classified as Non-combustible Class AA 1/1
  • Noise Reduction Coefficient NRC 1.1
  • Density 12Kg3
  • 135mm Aerolite Insulation Installed x Two Layer

Knauf Ecose Insulationon

  • Classified as Non-combustible Class AA 1/1
  • Noise Reduction Coefficient NRC 1.1
  • Density 12Kg3
  • 135mm Ecose Insulation Installed x Two Layers

Energylite Insulation

  • Classified as Non-combustible Class AA 1/1
  • Noise Reduction Coefficient NRC 0.9
  • Density 24Kg3
  • 50mm Enrgylite Insulation x Three Layer

Insulation That We Should Not Install Between Floors

We should not install combustible Insulation between floors. Because wooden floors are combustible, we must fit non-combustible Insulation that will prevent the spread of fire, ensuring the family’s safety.

  • Isotherm Insulation has a low NRC. However, the Insulation is also classified as combustible with a BB 1/2 fire rating.
  • Cellulose Insulation is also classified as combustible with Class BB 1/2
