Soundproof Windows

Our soundproof windows in Melbourne use advanced acoustic glass to reduce external noise by up to 80%, creating a quieter and more comfortable home.

Modern soundproof windows combine laminated acoustic glass with airtight uPVC frames to block both airborne and vibration noise.

Our Melbourne customers choose soundproof windows to reduce traffic, aircraft, and neighbour noise while improving thermal performance.

How Soundproof Windows Reduce Noise

How does different glass perform?

Rw is a value used to rate the effectiveness of a soundproofing in glass and other construction material. Increasing the Rw by one translates to a reduction of approximately 1db in noise level. Therefore, the higher the Rw number, the better a sound insulator it will be.

Research from the World Health Organization shows that long-term exposure to environmental noise can impact sleep and wellbeing — which is why installing soundproof windows makes a real difference in urban Melbourne homes.

Single glazing 4mm	28Rw
4mm/16 Argon/4mm	32Rw
4mm/14 Argon/6.76mm Acoustic Laminate	38Rw
6.76mm Acoustic Laminate/18 Argon/10.76mm Acoustic Laminate	43Rw
10.76mm Acoustic Laminate/26 Argon/10.76mm Acoustic Laminate	46Rw

An increase of 10 Rw units approximately halves the sound transmitted.

INSULATION AROUND THE FRAME

During installation, we apply expanding insulation foam around the frame perimeter to eliminate voids that could transmit sound.

ACOUSTIC LAMINATED GLASS

We use laminated acoustic glass with a special sound-dampening interlayer. This layer absorbs vibration and reduces airborne noise.

PROFESSIONAL INSTALLATION

Even the best soundproof window won’t perform without proper installation. Our team ensures the frame is sealed, levelled, and acoustically insulated to maximise noise reduction performance.

MULTIPLE CHAMBERED PROFILE

Our frames contain multiple internal chambers that interrupt sound wave transmission. These chambers act as acoustic barriers, breaking up noise vibrations before they pass indoors.

EXTERNAL CAULKING

Specialised sealants add an additional barrier between the window frame and the wall structure, helping block external noise infiltration.

LOCKING PONTS

Multiple locking points pull the sash tightly into the frame, increasing pressure on seals. This reduces micro-gaps where sound can leak through.

DUAL EPDM GASKETS

Each opening sash uses double EPDM rubber seals, preventing air gaps and significantly reducing sound penetration. Proper sealing is one of the most critical elements in noise reduction windows.

DOUBLE GLAZING

All units are double glazed as standard, with argon gas between panes to reduce sound vibration and improve thermal efficiency.

How Soundproof Windows Reduce External Noise

In busy urban areas, outside noise from traffic, aircraft, and neighbourhood activity can affect comfort, sleep, and productivity. Our soundproof windows are designed to significantly reduce external noise, helping create a quieter and more peaceful indoor environment.

Noise insulation performance is measured using the Rw (Sound Reduction Index) value. The higher the Rw rating, the better a window blocks sound transmission.

Standard single-glazed windows typically achieve around Rw 28
Advanced double glazed soundproof windows with acoustic glass can reach Rw 40–51, providing high levels of noise reduction suitable for urban and high-traffic areas

What Makes Our Soundproof Windows Effective?

Noise reduction windows combine several engineered components that work together to block and absorb sound:

Multi-Layer Acoustic Glass

Specially engineered laminated acoustic glass helps absorb both low-frequency noise (traffic, aircraft) and higher-frequency noise (voices, street activity).

Dual EPDM Sealing System

High-performance EPDM seals around opening sashes prevent air gaps, which are a major source of sound leakage.

Precision Frame Construction

Our multi-chamber uPVC frames reduce vibration transfer and help break up sound waves before they enter your home.

Professional Installation

Correct installation is critical for sound insulation performance. Our team ensures tight sealing, insulation around the frame, and elimination of gaps that could transmit noise.

High-Quality Hardware

Premium European hardware ensures long-term durability and maintains compression pressure on seals, helping preserve acoustic performance over time.

Result

The combination of acoustic glass, multi-layer sealing, insulated frames, and professional installation allows our soundproof windows in Melbourne to reduce external noise by up to 80%, depending on conditions.

Reviews

My window is a custom project with very thick glass. The main reason is reducing noise as much as possible. So the job done perfectly. The result is amazing. Thanks to Vladimir and Co. Highly recommend! Regards Dennis

Alex and his team recently did double glazing for us. It was a huge job with multiple large windows in a two-storey house. The windows are top quality with quality think glass. Windows Republic is great value for money and their quote was well below other companies. The noise and heat differences are noticeable. The final look and feel of the house are definitely a lot more premium. Thanks, Team!

Alex was great in understanding our needs and recommending the best fit for upgrading our windows to double glazing! We are very happy with the results and can highly recommend Windows Republic.

We're so thrilled with our new windows and doors, they've transformed our home! Great communication from Alex, timely work completed. Would definitely recommend to friends and family.
