In Australia, most people understand the advantages of insulating their roof and external walls, but did you know internal wall insulation has many benefits as well? Whether you’re building, renovating or wondering how you can make your home more energy-efficient, insulating your internal walls is a worthwhile investment.
Internal wall insulation can help make your home greener and reduce your power bill, but it can also have amazing acoustic and health benefits. Read on to learn about the advantages of internal wall insulation.
It’s well understood that insulation in the roof and external walls has energy saving effects by reducing dependence on artificial cooling or heating. But did you know interior wall insulation can also contribute significantly to energy savings?
With interior wall insulation, you can create climate zones within a building for more efficient heating or cooling. If you have rooms that aren’t occupied, you can shut their doors and only heat or cool the rooms being used. Internal wall insulation will resist the transfer of heat into or out of the room that is occupied. This is far more efficient than trying to artificially heat or cool the entire home.
More efficient heating or cooling leads to reduced energy consumption, and financial savings on your power bill. However, it is also a great way to make a building more environmentally friendly.
Installing any type of internal wall insulation will help reduce noise travelling from room to room. However, you can install specially designed acoustic insulation such as Soundscreen Insulation or Sound Shield Insulation which are very effective at reducing sound transfer. Specialised acoustic insulation products are thicker and more dense than regular thermal insulation, and can reduce noise levels by up to 75%.
Acoustic insulation brings with it many benefits such as creating private spaces and a peaceful indoor environment, and it will also increase the value of your building. Though you can install acoustic insulation in any internal walls, it is particularly recommended for bedrooms, bathrooms and laundries.
Health & Safety
Choosing high quality insulation for your internal walls can offer better moisture control to prevent rot, mold and mildew. These problems can be a potential health risk, and will drastically reduce the durability of your insulation. It is wise to choose insulation such as Knauf Earthwool that has non-hygroscopic properties, meaning it will not easily take up moisture from the atmosphere, and won’t rot or encourage the growth of mould or bacteria.
Some types of insulation such as Knauf Earthwool have non-flammable properties, and others such as James Hardie and Bradford Fireseal are considered ‘fire-proof’ because they help reduce the spread of fire. Increase the safety of your building by installing fire rated insulation in your internal walls.
What type of insulation is best for interior walls?
The type of internal wall insulation you choose will depend on your specific needs. Just remember the higher the R value, the more effective its thermal properties will be. The best insulation will also have sound reducing, moisture resistant and non-flammable properties.
