Window Soundproofing in Perth
Windows are almost always the weakest point in a room. Your walls are heavy and solid, but a standard window is a thin sheet of glass in a frame full of gaps, so traffic, trains, planes and the neighbours come straight through.
At Quash, we’ve been fixing noisy windows across Perth since 2009. In most cases you don’t need to rip anything out. We plug the gaps and fit a second, acoustic layer of glass behind the window you already have.
How Window Soundproofing Works
Sound gets in two ways: through gaps, and through the glass itself. We deal with both.
- Seal the gaps first. Even a small gap lets a surprising amount of noise through, so we always plug the holes first.
- Add a second layer with an air gap. Our SoundOut secondary windows sit behind your existing window, with the maximum air gap we can achieve for your windows.
- Use proper acoustic glass. Every SoundOut window uses 6.5 mm VLam Hush acoustic laminated glass, which blocks far more noise than standard glass.
The result is a clear improvement over your existing window. We always talk about results as an improvement on what you have now, rather than promising a fixed number of decibels.
SoundOut Secondary Windows
SoundOut secondary windows are custom made to suit your existing windows and fitted on the inside, so you keep your original windows. That makes them ideal for strata buildings and heritage homes, and usually the most cost-effective way to quieten a room.
- Sliding panels (most popular): open them to reach and clean your outer window.
- Fixed panels: available on request, fitted over your existing window where they comply.
- Custom made in powder-coated aluminium to suit your frames
- Fitted with 6.5 mm VLam Hush acoustic laminated glass
- Better thermal comfort in summer and winter as a bonus

Common Questions
Do I need to replace my windows?
Usually not. A SoundOut secondary window fitted behind your existing window is normally the most effective and cost-effective option.
Will I still be able to open my windows?
Yes. Our sliding panels open so you can reach and clean the outer window. Fixed panels are available on request where they comply.
Is secondary glazing allowed in strata buildings?
Usually, yes. It’s fitted on the inside and doesn’t change the outside of the building. Check with your strata first, and we can help with that.
How much does window soundproofing cost?
It depends on the size and number of windows. Our free online estimate gives you a real figure based on your measurements.
Does it help with heat and cold?
Yes. The extra layer of glass and the air gap also improve insulation.
