The Best Acoustic Insulation Batts to Create The Perfect, Peaceful Home

Which insulation is best for soundproofing a home

Looking for the best acoustic insulation batts in Australia? In this post our insulation experts will walk you through everything you need to know..

Noise pollution can have a big impact on our mental health and wellbeing. Whether it’s noisy traffic disturbing your sleep or feeling worried that your neighbors can hear you, managing noise levels within the home can make all the difference. 

Acoustic insulation batts are one of the most effective and cost-efficient ways to soundproof your home if you are building or renovating. Once installed, you’ll begin to experience the benefits straight away.

Why Invest in Acoustic Home Insulation?

The benefits of sound insulation include:

  1. Reduces Outdoor Noises – Acoustic insulation will reduce sounds from outside your home such as heavy traffic, noisy neighbours and barking dogs. 
  2. Provides Privacy – Acoustic batts work two ways. Not only will they reduce the amount of noise entering your home, they’ll also reduce noise from inside your home travelling outside. 
  3. Creates Acoustic Zones – Do you have particular rooms in your home that you want to keep quiet? Acoustic insulation can help you create sound sanctuaries inside your home, even if the kids are playing loudly in the games-room or someone is cooking up a storm in the kitchen.
  4. You Get Thermal Benefits Too! – Acoustic insulation will also slow down the flow of heat and increase your home’s energy efficiency. The main difference between sound insulation vs thermal insulation is that sound insulation is specially designed to be thicker and more dense to absorb sound. The R-Value of the product will tell you how much insulating power it has.

Where should I Install Acoustic Insulation?

You can install acoustic insulation throughout your home including the following places:

  1. External Walls – to soundproof against outside noises such as traffic, loud neighbours, aircraft, dogs barking etc.
  2. Internal Walls – to reduce noise transfer between rooms and keep key rooms quieter such as bedrooms, bathrooms and home theatres.
  3. Between Floors – to create quiet zones in your home and reduce noise transfer through the mid-floor of a multi-storey building.
  4. Ceilings – to minimise exterior noises, especially if you are directly under a flight path.

Best Soundproofing Insulation Materials

The most common materials to use in soundproofing your home are glasswool or polyester acoustic insulation batts.  

Glasswool Acoustic Batts

Glasswool – also known as fibreglass – is made from recycled glass materials. Glasswool is a very effective acoustic and thermal product which doesn’t attract vermin. It is treated with silicon to make it more water resistant.

Thanks to advancements in technology, glasswool has greatly improved over the last few decades with regards to its itch-factor. Modern products such as Earthwool Insulation and Pink Soundbreak batts are softer to touch and much more pleasant to handle than traditional glasswool products. 

Glasswool insulation also has a higher compression factor than polyester and other insulation materials. This means more batts can fit within the packaging, reducing delivery and storage costs.

Polyester Acoustic Batts

Polyester batts are made from recycled plastic bottles and other plastic materials. They tend to be more expensive than glasswool products but share the same benefits including excellent acoustic and thermal properties, rot-resistance, mould-resistance and vermin-resistance.

Having no breathable fibres, polyester is completely itch-free, soft to touch and pleasant to handle if you are planning a DIY project. Options such as Bradford Polymax batts are non-allergenic and safe for homes of people with asthma or dust allergies.

Ensure you have measured the area and know how much insulation is needed per square metre. Then decide whether you prefer polyester or glasswool insulation. We offer a range of reputable and durable acoustic insulation brands at Pricewise Insulation.

Be sure to choose an R-value that corresponds to the area in which you would like to insulate and your geographical location. 

For wall applications, we recommend:

  • At least R2.5 for cooler climates such as Melbourne, Sydney and Adelaide.
  • At least R2.0 for warmer climates such as Brisbane, Perth and northern NSW.

    Hi I’m building a sound room and am looking for the best sound proofing Batts to use, what do you recommend ?

      Hi Kevin,

      Thanks for your question. If you are retrofitting an existing room to create a music studio then we would recommend reading this blog post: How to Create a Podcast or Recording Studio.

      The number on the front of the packaging refers to the R-value, which measures how resistant the insulation is to heat transfer. If you are looking to purchase acoustic insulation then it is more important to look at the density of the insulation (kg/m3) or look for a product that has the word ‘acoustic’ or ‘sound’ on the package. Feel free to give us a call on 1300 729 639 if you have any further questions.

    Hi, I have a neighbour I share bedroom and common area walls with. I hear everything the neighbour does. What would be the best internal wall insulation to block out as much noise as possible?

    • Pricewise Insulation says:

      Hi Kira,

      Thanks for your question.
      We would recommend any acoustic wall batt product that has a R2.7HD rating which is 90mm thick, as this is the highest R-value and density rating available for internal wall insulation. We stock these products on our website, otherwise feel free to give one of our friendly team members a call on 1300 729 639 or email for more information.

      If you want to go the extra mile, we would recommend the sound check plaster board with resilient mounts for further soundproofing which can usually be purchased through your plasterboard supplier.

      Kind Regards,

      Pricewise Insulation
