Too much noise can have a serious impact on health and well-being. Whether you’ve got noisy neighbours, live near a busy road or airport, noise pollution can increase stress and negatively affect your overall quality of life. Noise transfer between rooms can be frustrating as well, particularly in rooms where the sound from the television can be heard throughout the house, and in home offices where noise transfer can be destructive.

Installing acoustic insulation into both your internal and external walls will help control the internal noise transfer between rooms such as media rooms, kids bedrooms, and laundry rooms along with external noise from traffic or aeroplanes. Acoustic insulation not only minimises the sound transfer between rooms but can add to the thermal performance, increasing a home’s comfort and energy efficiency.



There’s a growing trend to build on smaller lots which often means homeowners are electing to add a second storey to their home to increase the footprint of liveable space. Because there are no minimum standards for acoustic performance in the walls and floors of adjoining rooms, they are often overlooked when it comes to installing acoustic insulation.

Usually, it is not until the completion of the build when the homeowner receives the keys to their home that problems with noise transference are identified. This commonly results in decreased comfort levels within the home and can be very expensive to correct after the build has been completed.

Often this is a pre-existing issue in older homes too with occupants seeking solutions to make acoustic improvements to limit noise transfer and create a more peaceful space.
