Is spray foam good for soundproofing?

When you are looking to soundproof a room, there are many methods you can use. As the aim is to mute noise, you will want to choose an option that is proven to work and is within your budget.  

While you can pay to have rooms soundproofed professionally, this can be quite expensive.

Given this, a great way to create DIY soundproofing is to use spray foam. Though you may think that it is quite a difficult material to use and work with, it is surprisingly easy. In addition to this, it works well too. 

If you are creating a music room, or if you have noisy neighbors, it is a great solution to the noise problem. However, some types of spray foam will work better than others. Given this, you will want to purchase the best option. 

What is great about the spray foam is that it will reduce the amount of noise you can hear externally, and it will also help to keep sounds to one room, which is great if you enjoy playing louder instruments, such as the drums.

Ultimately, you can choose from a wide variety of different soundproofing foam sprays, as they will all help to reduce the noise well. While some will be easier to pipe than others, the process is fairly quick and simple to achieve. 

The Two Types of Spray Foam Insulation 

There are two types of spray foam that can be purchased, these are open cell and closed cell. When it comes to insulating walls in a home, you will want to use closed cell spray foam.

Closed cell spray foam is the best option to use with wood and timber. It expands up to 100 times its size when sprayed. As a result, you will actually need to use less foam than you will initially think.

 It is safe to use in the home, and it is a great way of adding a layer of soundproofing. Even the soundproofing spray foam will help to keep you home warm and insulated.

Open cell spray foam is typically used in buildings with a metal frame, such as in warehouses, or offices, for example. It is a great option to use if you need to soundproof these types of buildings, but it is not a suitable option for the home.

It only expands up to 50 times in comparison to the open cell foam. While it does not expand as much, it is more impermeable, which is better on the whole. 

As both types of foam are greeted with different buildings in mind, neither is typically better than the other. The type you choose will be based on the type of building you are looking to soundproof.

But, as there are two different types of spray foam available, we would recommend ensuring that you have purchased the correct one before using it.


We hope you have found this article useful and insightful. As you can see, spray foam is a great option to use for soundproofing. While there are better options to purchase on the whole, it is a great solution if you are looking to soundproof on a budget. 

As there are two different types of spray foam that can be purchased, you will want to ensure you are purchasing the correct one before using it. Using the wrong spray foam can cause potential problems with the walls of a building.
