Soundproof Windows Sydney

Are you tired of being kept up at night by street noise or your loud neighbors? Do you want to create a peaceful environment for yourself and your family? Soundproofing your windows can help you do just that!

At Inner West Window Specialists in Sydney, we can help you reduce the noise coming through from your old timber windows, so you and your family can get a good night’s sleep, enjoy watching TV without distraction, or have a quiet moment to yourself.

Timber Windows and Soundproofing

Timber windows are great for heritage homes and can add value to a property. However, old timber, especially if not properly maintained, can allow noise to easily pass through into the home. To soundproof timber windows, you will need to install thick glass panes, heavy frames, and multiple layers of insulation.

The sound transmission class (STC) rating is the most commonly used metric to measure how well a window can reduce noise. The higher the number, the better insulated it is. At Inner West Window Specialists, we can provide soundproofing solutions with STC ratings of up to 40 or higher.

Soundproofing Timber Windows: Why You Should Do It

There are several benefits to soundproofing windows, and the process is not as difficult or costly as you might expect. Here are some of the benefits of soundproofing windows:

Reduces external noise

Soundproofed windows help with external noise reduction, allowing you to enjoy a quiet environment. This is especially useful if you live in a noisy area or near a busy street. We can also soundproof your primary window, while your secondary windows can remain open to provide natural light and ventilation.

Improves the quality of sound inside your home

Not only do soundproofed windows reduce external noise, but they also improve the quality of sound inside your home. This means that you’ll be able to enjoy music and movies more clearly, and any conversations you have will be easier to hear. Sound insulation also helps reduce echoes in the room.

Increases energy efficiency

Soundproofed windows can help keep your home warmer in winter and cooler in summer. This means that your energy bills will be lower, and you won’t have to rely as much on air conditioning or heating.

Increases privacy

Noise reduction windows provide an extra layer of privacy, as they prevent sound from entering or leaving your home. This means that you won’t have to worry about people overhearing your conversations or other noise from inside your home.

Our Soundproofing Services: The Best in the Region

There are many ways to soundproof windows including acoustic insulation, weatherstripping, and glazing. Some DIYers use spray foam insulation or soundproof curtains, but these methods are not as effective and usually develop poor sound insulation performance overtime.

Inner West’s experienced team of experts has worked on hundreds of projects, from residential homes to commercial buildings. We have soundproofed windows for many reasons, including improving noise control and increasing privacy.

Below are some of our soundproofing solutions:

Acoustic Insulation

We install acoustic insulation to reduce the amount of sound that can pass through your windows. This insulation is designed to absorb sound, so it won’t let any noise in or out. Acoustic insulation uses different materials such as glass, foam, and metal to block sound.


We also use weatherstripping to reduce the amount of sound coming through your windows. This is a moisture-resistant material that will prevent air from passing through your windows, which can then help reduce noise levels.


Glazing is a process that adds multiple layers of glass to your windows. This creates a barrier between the window and its frame, which helps to block sound from entering or leaving your home.

Double-glazing is one of the most effective soundproofing techniques, as it provides an extra layer of protection. When you have double-glazed windows, you are able to enjoy a much quieter environment while still being able to enjoy natural light.

However, a secondary glazing system may not fit if you want your traditional timber windows to look aesthetically pleasing. The good news is that our team will work with you to customise the best soundproofing solution that works for your home.
