Soundproof Windows
Silence the Outside World.
European double- and triple-glazed windows built with certified acoustic glass packages. Laminated acoustic glass, asymmetric panes and argon or krypton gas fill cut outside noise by up to 51 dB, up to 90% quieter inside.
Soundproof windows reduce outside noise using laminated acoustic glass, asymmetric pane thicknesses and argon or krypton gas fill inside a sealed double- or triple-glazed unit. WindowPlus acoustic glass packages are a certified special construction that can cut noise by up to 51 dB, a reduction of up to 90% in perceived loudness, ideal for Perth homes near busy roads, train lines, flight paths or schools.
Why Soundproof Windows
Peace and Quiet, Engineered In
Noise is a primary cause of sleep disturbance. Our certified acoustic glass packages restore calm by blocking the outside world at the window, the biggest and easiest source of noise to treat.
Certified Acoustic Glass
A certified special-construction glass package, independently rated for its sound-reduction performance (Rw rating), so you know the result before you order.
Up to 51 dB Quieter
Our acoustic packages reduce outside noise by up to 51 dB, a reduction of up to 90% in perceived loudness. A busy road becomes near-silence indoors.
Laminated Acoustic Glass
A special acoustic film (PVB interlayer) bonded between glass panes damps the vibrations that ordinary glass would otherwise transmit straight into your room.
Argon & Krypton Fill
The sealed cavity between panes is filled with dense argon or krypton gas. Heavier than air, it slows both sound and heat transfer, so you get quiet and energy efficiency together.
The Special Construction
How Our Acoustic Glass Packages Work
A soundproof window is a system. Four elements work together in every WindowPlus acoustic unit, and the whole package is certified for its combined performance.
1. Laminated Acoustic Glass
Two panes of glass are bonded with a thin acoustic PVB interlayer. This membrane absorbs sound vibrations that solid glass would otherwise pass straight through. Lamination also adds safety and security, the glass holds together if broken.
2. Asymmetric Pane Thicknesses
Every pane resonates at a certain pitch. By pairing panes of different thicknesses, each pane cancels the frequencies the other lets through, so the unit blocks a much wider range of noise, from deep traffic rumble to sharp aircraft and voices.
3. Argon or Krypton Gas Fill
The sealed void between panes is filled with an inert, low-conductivity gas, argon or krypton, that is denser than air. It slows the transmission of sound vibrations across the cavity, and at the same time keeps the inner glass close to room temperature for better energy efficiency.
4. Multi-Chamber Frame & Seals
The best glass fails if noise leaks around it. Our multi-chamber uPVC and thermally broken aluminium frames with continuous compression seals close every gap, so the whole window performs to its certified acoustic rating, not just the glass.
Certified Performance
A Certified Special-Construction Package
Acoustic glass is not a single product, it is a specification. Our special-construction acoustic units combine laminated acoustic glass, asymmetric panes, argon or krypton fill and a sealed multi-chamber frame, and the finished package carries a certified acoustic rating (Rw) for that exact configuration.
That means the quiet you are promised is measured, not marketing. We tell you the acoustic rating for the package quoted so you can match it to your noise source, whether that is a main road, a rail line or a flight path.
- Certified acoustic (Rw) rating for the exact glass package
- Special-construction laminated acoustic glass as standard
- Argon or krypton gas fill for sound and thermal performance

Who Benefits Most
Restore Peace Wherever Noise Steals It
Without enough sleep we are left irritable, stressed and sluggish. Soundproof windows help most where noise is constant or arrives at the worst times.
Busy Roads
Homes on main roads, highways and intersections with constant traffic rumble.
Train & Rail Lines
Properties near passenger or freight lines where trains run early and late.
Flight Paths
Suburbs under approach and departure paths where aircraft noise peaks sharply.
Schools & Parks
Living beside a school, sports ground or playground with daytime activity.
Shift Workers
Anyone sleeping during the day who needs a dark, quiet room out of step with the street.
Nurseries
Babies and young children who wake easily to sudden outside noise.
Entertainment Districts
Homes near bars, venues and nightlife where noise runs late into the night.
Neighbourhood Noise
Barking dogs, mowers, neighbours and general suburban background noise.
