Every Thing You Need to Know About Acoustic Insulation
Did you know many modern homes often don’t have internal wall insulation? Because of this noise travels easily between rooms. You might hear conversations from the next bedroom, the television from the lounge, or footsteps from the hallway. Acoustic insulation is not required in the building code, so builders often leave these walls empty to cut costs.
How Acoustic Insulation Reduces Sound
Sound moves through air and solid materials in waves. When these waves reach a surface, they can pass through, bounce off, or be absorbed. Hard materials like plasterboard and timber reflect sound, which is why noise travels easily through empty internal walls.
Acoustic insulation works because it is made from soft, fibrous material that absorbs sound energy. When blown insulation fills the wall cavity, it creates a dense layer that traps and slows sound waves. This reduces the amount of sound that can pass through the wall.
Blown acoustic insulation is especially effective at reducing mid to high frequency noise. This includes talking, televisions, music, and many household sounds. Homes feel calmer and more private because noise from one room no longer spreads to the next.
How We Install Acoustic Insulation
We use a simple and tidy process to install blown acoustic insulation. It delivers immediate results and does not cause major disruption to your home.
Home Assessment
A Local Advisor visits your home to assess your current insulation and understand your goals. We take a close look at your internal walls and check if they have any existing insulation. We then explain the best way to add acoustic insulation and answer any questions you may have. The assessment helps us plan a smooth installation.
Installation
On the day of installation, we use specialised equipment to blow acoustic insulation into your internal walls. Small holes are made in the plasterboard so we can fill the entire cavity. The insulation is blown in under pressure, which helps it reach every corner. This method ensures a complete fill, so there are no gaps where sound can escape.
Once the insulation is in place, it stays there for the life of the building. It does not slump or settle. It continues to absorb sound day after day, giving you long term noise control without the need for further work.
Finishing Touches
After the insulation is installed, we tidy up the area and repair the small access holes in your walls. We make sure your home looks the same as when we arrived, the only evidence we were there will be a quieter home we leave behind.
No council consent needed for internal walls
If you’re only insulating your internal walls, you don’t need council consent. This makes the process even easier, so you can get the job done sooner.
