Townhouses have a shared wall and it’s important to understand how sound travels between the two homes.

You will need to find a way to regulate sound to make sure it does not spread too much. The same goes for ensuring sound does not keep flowing into the townhouse from the other home.

This is why you will want to consider a soundproof shared wall townhouse.

To soundproof a shared wall in a townhouse, start with a sound absorber on the wall, apply acoustic paint, use resilient clips, and install soundproof curtains.

If you are looking for a more permanent fixture then it’s best to consider decoupling the wall.

Tips On How To Soundproof Shared Wall Townhouse

1. Apply Shock Absorbers To Thicken Wall

The best way to reduce sound from a shared wall in the townhouse is to consider shock absorbers.

These are wonderful because you are going to dull the sound instantly.

Sound waves travel easily when there are gaps in the wall and/or the wall is not thick. Most builders are going to create a relatively thick wall between the two homes but that might not be enough.

This is why you will want to soundproof a townhouse by looking at installing shock absorbers.

The shock absorbers need to be installed from end to end on the wall.

This is going to thicken the shared wall and make it much harder for the sound waves to get through. This is the type of control you are going to get instantly and it is advantageous for those who want to do things the right way.

2. Apply Acoustic Paint

You will also want to think about a secondary option, which is going to come in the acoustic paint.

A lot of people will think about creating a two-tiered solution to soundproof a townhouse.

The idea is to apply a coat of acoustic paint, let it dry, and then set up the shock absorbers on the shared wall.

This is going to help muffle the noise immediately and make it much harder for sound waves to travel between the two homes. This is a must when the noise is excessive as you will need multiple layers of protection.

3. Use Resilient Clips

This is a far more robust solution that is going to take time to manage.

The purpose is to look at using resilient clips between the shared wall as a way to create more distance between the two.

This is going to require quite a bit of work and it’s best to get a professional to work on it. However, this will muffle the noise well and it is a good solution for those who find the noise unbearable.

On the same line, you can also look to decouple the shared wall to make the gap wider.

4. Set Up Soundproof Curtains

Depending on where the sound is coming from, it might just be the case of sound coming from somewhere else in the room.

You might think it has to do with the shared wall but it could be from the window nearby.

As a result, you will also want to take the time to set up soundproof curtains in the house. This will make it a lot easier to muffle the noise and make sure it is under control.

Soundproof curtains are a great solution that is easy to set up and you can find what you are on the hunt for instantly.
