How To Soundproof a Floor

Hearing noise between floors above or the impact of footsteps can become a point of frustration for some in a home. What can be done to reduce the noises you hear, or even stop them?

There are a few ways that you can soundproof a floor. One is to install acoustic insulation. Other options are acoustic flooring, acoustic underlay which can be bought as a roll, or pre-made acoustic panels. If you are looking for a cheaper solution or a quick fix, there are other things that you can do.

One way to soundproof a floor is to add rugs or runners on top of the flooring that you have. This will help to muffle the noise. You can also put furniture on the floor to help with sound absorption. If you have hardwood floors, you can add area rugs to help with the noise.

Another way to soundproof a floor is to use things like door sweeps and weather stripping. This will help to seal off any gaps that might let sound through.

Let’s take a look at 3 proven solutions. These can be expensive, but the results compared to some of the cheap and quick solutions are night and day.

1. Acoustic Insulation

This is one of the most effective ways to soundproof a floor. By installing acoustic insulation, you are creating a barrier between the noise and the room. This will help to reduce the level of noise that you hear.

Rockwool is the best acoustic insulation on the market due to the high density of the material. The most commonly used product is RWA45, which has 4 thicknesses – 25mm, 50mm, 75mm, and 100mm. This is a mineral wool insulation with a density of 45kg/m3. It is the density that reduces noise, as the soundwaves have to travel through more material to get through to the other side.

Rockwool also has the RW3 – 50mm, 75mm, and 100mm, with a density of 60kg/m3. And lastly RW5, with the latter being the densest slab at 100kg/m3, making it the best acoustic insulation product from Rockwool.

2. Acoustic Floor Boards

Acoustic floor boards are another great way to soundproof a floor. These boards are made of a material that is designed to reduce the amount of noise that is transmitted through the floor.

Hush Panel 28 is one of the best acoustic floorboards on the market. It is made of 18mm thick P5 tongued and grooved with a patented 10mm Hushfelt. The boards can be used as standalone flooring or fixed onto the existing flooring.

3. Acoustic Underlay

If you are looking for a more affordable way to soundproof a floor, acoustic underlay is the best option. Acoustic underlay can be bought as a roll, and it is easy to install.

There are a few different types of acoustic underlay that you can choose from. One of the best is the Soundbloc range. This range has a variety of products that will suit your needs. The Soundbloc range includes Soundbloc Classic, which is a 2mm thick rubber with a foil facing.


Ultimately your decision will come down to the level of noise you can hear between floors. If the noise is mild and occasional, then you may be able to get away with a less expensive solution. If the noise is more severe, then you will need to invest in a more expensive option. No matter what your budget is, there is always an effective way to soundproof a floor.
