Soundproofing Insulation


Sound Insulation

Reduce sound transmission from outside the home or between rooms with acoustic insulation. Soundproofing insulation products are often referred to as high-density or hi-performing products.


Focus on Service

Pricewise Insulation is one of New Zealand’s largest online stores for sound insulation. We stock the major insulation brands including Knauf Earthwool, Autex Greenstuf and Bradford Insulation.


Upgrade from thermal to acoustic

Upgrading from R2.0 to R2.5HD wall insulation will improve both the thermal and acoustic performance of your home. We recommend installing sound insulation in internal walls, particularly around the theatre room and office.

Soundproofing (Acoustic) Insulation

Excessive exposure to unwanted outside noise can lead to stress, sleep disturbance and has been linked to many other health complications. Road traffic is one of the biggest sources of noise pollution. Persistent noise within the home – for example music, tumble dryers, kitchen appliances etc. – can also have a negative impact on quality of life in the home.

How does interior wall sound insulation work?

While many home owners naturally include acoustic insulation in their exterior walls to block out external noises, many unwanted sounds are actually created within the four walls of the house. Sound insulation for walls within the house helps to reduce the transmission of sound from room to room by absorbing the vibrations that would otherwise have passed through. Many sound insulation products have the added benefit of providing thermal insulation for temperature control.

Stress, Noise and Acoustic Insulation

There are two primary reasons to consider installing sound insulation in your home. The one is to reduce outside noise such as traffic, aircraft, barking dogs etc from entering the building interior. (Typically, this means installing high density thermal and acoustic insulation in the external wall of the home, which forms an effective sound barrier.) The second reason is to reduce the level of sound that is transmitted from room to room. Use common sense when considering this additional investment, and think long term, keeping in mind that it’s far easier and cheaper to install sound insulation during the new building project. Media/TV rooms, studios, bedrooms, bathrooms and laundries should be first on the priority list.
