Make Your Home Quieter
Reduce unwanted traffic, aircraft and neighbourhood noise with acoustic windows designed around your property.
Effective noise reduction depends on the complete system.
Thicker glass generally has greater mass, which can improve resistance to sound transmission.
However, thicker glass alone does not solve every noise problem.
Using panes of different thicknesses helps prevent both panes from responding to the same sound frequencies.
This can improve performance compared with two identical panes.
The space between panes plays an important role in acoustic performance.
In many configurations, a wider air gap can improve low-frequency noise reduction.
Even high-performance glass can underperform if sound leaks around the sash, frame or installation perimeter.
Effective seals are essential to the performance of the complete window.

Upgrade your windows with custom acoustic glazing designed to reduce outside noise and improve everyday comfort.
| Laminated Glass | Standard Double Glazing | |
|---|---|---|
| Construction | Multiple glass layers bonded with an interlayer | Two separate panes divided by a sealed cavity |
| Acoustic benefit | Interlayer helps damp vibration | Air cavity helps isolate sound transmission |
| Low-frequency noise | Can perform strongly depending on specification | Performance varies significantly with glass and cavity |
| Thermal performance | Depends on overall window system | Generally stronger thermal benefit |
| Safety | Laminated interlayer holds broken glass together | Depends on glass selected |
| Best use | Acoustic, safety and security applications | Combined thermal and general acoustic improvement |
Neither is automatically better for every property.
For serious noise problems, a configuration combining laminated glass, asymmetric pane thicknesses and an appropriate air gap may outperform basic double glazing.
The correct specification should be matched to the frequencies you’re trying to reduce.
Noise follows the easiest path into a room.
Small gaps around window sashes, seals and frames can significantly reduce the benefit of upgraded acoustic glass.
Quality acoustic windows should therefore address:
A high-performing glass configuration installed in a poorly sealed frame will not deliver its full acoustic potential.
Acoustic window performance is commonly expressed using Rw and Rw+Ctr ratings.
Rw is a single-number rating used to describe how effectively a building element reduces airborne sound across a range of frequencies.
Higher Rw = greater overall sound reduction.
Rw+Ctr gives additional consideration to lower-frequency noise.
This can be particularly important for:
For homes affected by traffic or aircraft noise, Rw+Ctr can be more useful than looking at Rw alone.
Don't Guess At Acoustic Glass
The best soundproof window isn’t simply the thickest glass or the most expensive double glazing.
We’ll help you choose a window system designed around the noise affecting your property.
Full window replacement isn’t always necessary.
Secondary glazing adds another glazed layer inside the existing window opening, creating a larger air gap between the original window and the new internal panel.
For some acoustic applications, the wider cavity created by secondary glazing can provide excellent noise reduction while allowing the existing external window to remain in place.
It may be particularly useful where:
Windows aren’t always the largest path for external noise.
Large sliding and glazed doors can contain significantly more glass than the surrounding windows and may become the weakest point in the room.
If you’re upgrading windows for noise reduction, the doors should be assessed at the same time.
Ready for a Quieter Home?
Reduce unwanted outside noise with acoustic window solutions tailored to your property and the type of noise you’re dealing with.
Acoustic windows generally cost more than standard glazing because the glass specification and window system need to be selected for measurable noise reduction. Pricing depends on:
The best way to compare acoustic window options is by considering tested performance as well as price.

No window can realistically eliminate every external sound. Acoustic windows are designed to reduce noise transmission, with performance depending on the glass, frame, seals, installation and type of noise.
Yes. Double glazing can reduce external noise, but acoustic performance depends heavily on pane thickness, the difference between pane thicknesses, cavity width and sealing. Standard double glazing should not automatically be assumed to be the best acoustic configuration.
Yes. Laminated glass can provide strong acoustic performance because the interlayer helps damp vibration through the glass.
It depends on the noise source and the glazing specification. Laminated glass may perform better than basic double glazing against certain frequencies, while specialised double glazing can combine laminated panes, asymmetric glass and a larger cavity for stronger acoustic performance.
There is no single ideal thickness. Performance depends on the complete configuration, and using panes of different thicknesses can often be more effective than simply using two identical thick panes.
Increasing glass mass can improve sound reduction, but thickness alone isn’t enough. Resonance, air gaps, laminate and seals also influence performance.
A wider cavity can improve acoustic isolation, particularly at lower frequencies, although performance depends on the complete glazing system.
Rw is an acoustic rating used to describe airborne sound insulation across a range of frequencies. Higher values generally indicate better overall sound reduction.
Rw+Ctr adjusts the rating to account for lower-frequency noise and can be particularly relevant when assessing traffic and aircraft noise.
Yes, when the glazing and window system are selected specifically for the frequencies associated with road traffic.
Acoustic windows can significantly reduce aircraft noise, but the required configuration depends on the intensity and frequency profile of the noise at the property.
Acoustic PVB is a specialised laminated-glass interlayer designed to help damp sound vibration more effectively than standard configurations.
Yes. Gaps around the frame and sash allow sound to bypass the glass, so effective sealing is critical to overall window performance.
Secondary glazing can provide excellent acoustic performance because it can create a substantially larger air gap while allowing the existing external window to remain.
The best option depends on the condition of your existing windows, the noise problem, required performance, appearance and budget. Both options should be assessed before deciding.
Yes. Sliding windows can be designed for improved acoustic performance, although the sealing and frame system need careful consideration because sliding components can create potential noise paths.
Large glazed doors can be a major noise path and should be considered alongside the windows when designing an acoustic solution.
Pricing depends on the window size, glass configuration, frame system, acoustic seals and installation requirements. We provide project-specific quotes rather than relying on generic acoustic window prices.
Yes. We provide custom acoustic window and glazing solutions for homes and projects across Sydney.
Yes. Send us your suburb, photos of the existing windows and details about the noise source and we’ll help you assess the available options.
From traffic and aircraft noise to trains, barking dogs and general neighbourhood noise, the right acoustic glazing can make a significant difference to indoor comfort.
