Internal wall insulation is especially important for homes and buildings in Australia, where temperature variations can be extreme. Internal wall insulation makes it easier and more efficient to set and maintain varying temperature zones within a single home or office building. Not only does internal wall insulation help keep you comfortable in all climates, but it also provides soundproofing benefits, energy savings, and helps to reduce noise transfer between rooms.
Internal wall insulation is best installed during the building or renovation process, because once the plasterboard is up, installing insulation in your walls will become much more complex and costly.
Popular Materials for Internal Wall Insulation
There is a range of materials that are suitable for insulating internal walls, each with unique benefits. The right material for you will depend on your specific needs, such as climate, soundproofing requirements, and budget.
Best Thermal Insulation Options for Internal Walls
Thermal insulation helps regulate your indoor temperature, keeping your home cooler in summer and warmer in winter. Internal wall insulation also allows you to create temperature zones, giving you the flexibility to heat or cool rooms based on their usage at different times of the day.
- Fibreglass Batts: These are some of the most cost-effective and commonly used materials in residential properties. They provide good thermal performance and are easy to install.
- Polyester Insulation: A sustainable choice with good thermal resistance, polyester insulation is non-toxic and often made from recycled materials.
- Rigid Foam Boards: Foam boards provide superior insulation performance for a high level of energy efficiency. They are commonly used in areas where maintaining stable temperatures is important, such as wine cellars, garages, or home studios.
Top Acoustic Insulation Solutions for Internal Walls
If noise reduction between rooms is a priority, acoustic insulation materials help absorb sound and minimise sound transfer.
- Glasswool Insulation: A versatile all-rounder, glasswool is ideal for absorbing both airborne noise (such as conversations and television sound) and can also help reduce some impact noise (such as loud footsteps). Glasswool also offers excellent thermal performance.
- Rockwool Insulation: This material is dense and is particularly effective at reducing airborne noise, making it a great choice for shared walls or noisy environments. It also offers great thermal performance.
- Acoustic Foam Panels: These panels are purpose-built for soundproofing applications. Acoustic foam panels like those from Autex are ideal for home theatres or music rooms where advanced noise control is important.
How to Choose the Right R-Value for Internal Wall Insulation
R-value measures a material’s ability to resist heat flow. Choosing the right R-value ensures that your insulation performs effectively, helping you improve indoor comfort and save on energy bills.
When it comes to how to insulate internal walls with the right R-value for your needs, it’s essential to consider your climate and energy efficiency needs. In Australia, you must meet or exceed your energy report’s minimum requirements. The ideal R-value range for a standard internal wall is R2.0-R2.5. For properties exposed to more extreme temperatures, a higher R-value is recommended.

Frequently Asked Questions About Internal Wall Insulation
Internal wall insulation is a type of insulation that is installed within interior walls to improve thermal efficiency and reduce noise transfer between rooms.
Internal wall insulation helps maintain consistent indoor temperatures, reduces energy use, and improves acoustic comfort. It’s particularly important in regions of Australia that are exposed to extreme weather and in open-plan homes.
When it comes to how to insulate internal walls, you should do it at the construction stage. Install insulation between wall studs and before plastering. Start by measuring and cutting the batts to size. Press them into place, ensuring there are no gaps. Secure the batts if necessary. Once installed, cover with plasterboard or appropriate wall lining.
Yes, you can add internal wall insulation to an existing building, although it requires removing the existing plasterboard or other wall lining. Alternatively, blow-in insulation methods can be used to minimise structural disruption.
Internal wall insulation helps absorb airborne noise between rooms, helping to reduce noise from televisions, conversations and appliances.
Savings will vary based on your energy consumption and rates, but internal wall insulation helps stabilise internal temperatures and reduce heat loss, which provides improved energy efficiency.
