What type of insulation is best for soundproofing? 

Soundproofing insulation solutions have proven useful across a variety of applications, ranging from apartment buildings to processing plants and factories.

Polyurethane spray foam and glasswool insulation are two well-known materials, but there are many different options for sound insulation. The type you choose will depend on a number of factors, including the application, the environment, and your budget.

So, what type of insulation materials are best for soundproofing? Let’s take a look.

What Is Soundproofing?

There are two main types of sound: airborne and impact. Airborne sound is generated by vibrations in the air, such as noise from machinery, traffic, or people talking. Impact sound is caused by vibrations through solid surfaces, such as footsteps or equipment collisions.

Soundproofing is the process of reducing the transmission of sound. In some cases, you may want to reduce the overall noise level in an area. In other cases, you may need to block out specific sounds.

This process can be completed in many different ways, from using sound-absorbing insulation materials to installing sound-dampening panels.

There are many different types of acoustic insulation, including fibreglass, Rockwool, cellulose, and spray foam insulation. Each type has its own advantages and disadvantages, so it’s important to choose the right one for your needs.

Why Soundproof?

There are many different reasons to soundproof homes and businesses. Sound transmission can interfere with communication, concentration, and sleep. In some cases, it can even be a safety hazard.

Businesses often require soundproofed meeting rooms and offices, meaning a commercial office space with adequate soundproofing is essential. If you’re building a new home or planning a new development near a main road or the city, then soundproofing will be a must.

Below are a few reasons you may want to consider installing soundproofing insulation in your home or commercial or industrial building.

Improved Communication

It can be difficult to have a conversation in a noisy environment. Those that work in an office may find it difficult to concentrate with the sound of people talking and phones ringing. By soundproofing your space, you can improve communication and make it easier to hear what others are saying.

Increased Productivity

Noise can be a major distraction, especially if it’s constant or grating. If you work in a noisy environment, you may find it difficult to focus on the task at hand. This can lead to lost productivity and, ultimately, decreased profitability. Blocking sound transmission can help to keep people focused and on track.

Reduced Stress Levels

Unnecessary noise can also be a source of stress. If you’re constantly bombarded with noise, it can lead to anxiety. Soundproofing can help improve the sound quality of your home or office and make it more pleasant to live or work in.

Better Sleep

If you live on a busy road, or in a noisy neighbourhood, you may find it difficult to get a good night’s sleep. Outside noise can interfere with your natural sleep patterns and leave you feeling exhausted during the day. By soundproofing your bedroom, you can create a calm and quiet environment that’s conducive to rest.

Sound Insulation Materials

One of the most effective ways to reduce airborne noise is to use acoustic insulation. This type of insulation works by absorbing sound waves and reducing their intensity.

When it comes to soundproofing, Advanced Insulation & Fabrications offers insulation solutions for both homes and businesses. We offer a range of products, including polyurethane spray foam and mineral wool insulation such as glasswool and Rockwool.

For those interested in acoustic soundproofing insulation, there are several options available.

Glasswool Insulation

Glasswool insulation is a form of acoustic insulation that can be implemented in residential, commercial, and industrial spaces. It’s great for when you want to absorb sound.

This type of insulation is ideal for both airborne and impact sound. It’s primarily made from recycled glass and is available in a range of densities. As a general rule, the thicker the insulation, the better it is at soundproofing.

Glasswool insulation is also a good choice for those looking for an eco-friendly option as it’s made from recycled materials. This product also provides efficient insulation, trapping air within the glass fibres.

Rockwool Insulation

As the name suggests, Rockwool insulation is comprised of a stone-based mineral fibre, or, to put it simply, rocks.

This type of insulation offers effective sound-deadening and generally is comprised of up to 75 per cent recycled materials. It’s fire-resistant and perfect for placing in interior walls and ceilings, floors, and other spaces that require insulation and sound absorption.

Polyurethane Spray Foam

Spray foam insulation is a popular option to reduce sound transmission. It’s designed to be sprayed directly onto surfaces to fill gaps in a space. Polyurethane spray foam can reduce noise levels from vessels, equipment, and buildings by as much as 75%.

This type of insulation is perfect for those difficult-to-reach areas, such as small crawl spaces and along spots that need sealing. It quickly expands and hardens to create an airtight seal that will absorb sound and significantly reduce noise transfer.


Polystyrene can be installed as a soundproofing material. It’s a type of plastic that’s made up of small beads of styrene. This soundproofing option provides affordable acoustic panels for homes and businesses.

This material that’s often used as an impact-resistant surface for packaging is also found in some types of insulation. When used for soundproofing, it can a cost-effective method for absorbing noise.

Insulation mats

These rubber mats are generally used in areas that require protection from electrical shocks. However, they can also be utilised as a form of soundproofing.

The mats are placed on the floor, creating a barrier that helps to reduce noise transmission. They’re often used in areas where heavy machinery is operated, such as factories and warehouses.

Commercial & Industrial Insulation Solutions

Advanced Insulation & Fabrications can provide many commercial and industrial insulation solutions. We work with our clients to develop customised insulation designs.

We have a wealth of experience in the commercial and industrial sectors, and we’re familiar with the unique challenges and requirements that can present themselves in these spaces.

Residential Solutions

Individual residential buildings will generally have smaller budgets and less space to cover than commercial builds, however, this isn’t always the case.

Apartment buildings often house a high number of people in close proximity to one another, meaning that soundproofing can be a highly important consideration. In these cases, it’s often necessary to soundproof common areas, such as hallways and stairwells, along with individual living spaces.

Soundproofing can be a challenge in residential settings, however, our team has the experience and expertise to develop an effective solution for your home or unit building.

We can provide soundproof insulation for both older single-dwelling spaces and large new-build apartment blocks.

Which Acoustic Insulation is Best for Soundproofing?

The best type of insulation for soundproofing depends on your specific needs. For example, if you own a manufacturing business, your sound insulation needs are going to be quite different from those that own a small office.

The soundproofing needs for a residential space will be different again. At the crux of it, the type of insulation that’s best for you depends entirely on your circumstances, and it’s important to work this out before you begin your project.

Factors to consider include your budget, your space, and the level of sound absorption you require.

Your Budget

Your budget is an important factor when deciding which insulation soundproofing material to use. Some materials are more expensive than others, so it’s important to start researching with a budget in mind.

If you have a large budget, you’ll have more options available to you. However, there are still effective insulation materials that can be used for those with smaller budgets.

Your Space

The size and shape of your space will also influence your decision. Some sound absorption materials are better suited to larger spaces, while others can be used in smaller areas.

You’ll need to take into account the amount of space you have available, as well as any obstacles that might be present, such as pillars or ductwork.

Level of Soundproofing Required

The level of soundproofing you require will also play a role in deciding which insulation material to use. If you need a high level of soundproofing, you’ll need to select an insulation material that’s effective at absorbing noise.

Those that are after simple sound-deadening may be able to get away with using a less expensive material.

Once you’ve considered all of these factors, you can begin to look at the different types of insulation material that are available.

Soundproofing Insulation Options

There are lots of different types of soundproofing insulation out there, and not all will be suitable for your needs. Common types of soundproofing insulation materials include:
