Double Glaze Your Windows to Reduce Noise & Improve Temperature Inside

Tired of hearing every car, truck and neighbour through your windows? Is your room too cold in winter or hot in summer? Is condensation damaging your window frames?

We retrofit a magnetic or sliding window system in front of your existing windows to create a double glazing effect – no need to pull them out and start again.

You get proper noise reduction plus better insulation, which means lower power bills.

The air gap between the windows reduces sound and heat transfer.

It’s tested technology that actually works – our magnetic system has been independently tested by NATA to prove it reduces noise significantly.

Why Install Magnetic or Sliding Soundproof Windows

Reduce Outside Noise
Traffic, construction, aircraft, industrial noise – it all adds up and affects your quality of life. Whether you’re trying to sleep, work, or just relax at home, constant noise is exhausting. Our double glazing systems make a real difference in homes, offices, and commercial buildings.
Better Sleep
Road noise and neighbourhood sounds can wreck your sleep. Install our systems in bedrooms and you’ll notice the difference immediately. Better sleep means better health and mood.
Improved Work Environment
Noisy offices kill productivity. It is hard to concentrate when you can hear everything happening outside. Our commercial installations create quieter workspaces that people actually want to work in.

Lower Energy Bills
Double glazing isn’t just about noise – it’s excellent insulation too. Less heat loss in winter, less heat gain in summer. Your heating and cooling systems won’t have to work as hard.
Increase Property Value
Quality soundproofing and thermal improvements are selling points buyers look for. It’s an upgrade that pays for itself over time.
Weather Protection
Storm noise, heavy rain, and wind can be just as disruptive as traffic. Our systems help with all external noise sources.

Our Window Systems

Magnetic Double Glazing Windows

Popular Choice for Homes and Offices

Our magnetic double glazed window system uses clear acrylic panels that attach to your existing windows with magnetic strips.

Simple concept, but very effective results.

Key Features:

Magnetic seal creates airtight barrier
Aircraft-grade acrylic won’t yellow or crack over time
Better light transmission than glass (92% vs 90%)
Superior insulation properties – you can feel the difference
NATA laboratory tested for acoustic performance
Custom manufactured to fit your exact window dimensions

The magnetic attachment system is clever – panels come off easily for cleaning then seal back perfectly in place.

Why Acrylic Windows Work Better:

They let in more natural light than glass
They have much better thermal insulation – touch a glass window and an acrylic window on a hot day and you’ll understand
They are removable which makes it easy to clean

The aviation industry uses acrylic for aircraft windows for good reason.

Magnetic Double Glazed Soundproof & Thermal Windows are best used for:

Residential homes and apartments
Small commercial offices
Anywhere you want good results at a reasonable cost
Windows where easy removal for cleaning is important

Installation Requirements

Getting the Setup Right

You need enough space between your existing window and the inside window frame for our system to work properly.

We like to have about 100mm to work with, but we can make smaller gaps work if that’s what you’ve got.

Our systems typically achieve Rw40-43dB noise reduction ratings – that translates to a noticeable difference in how much outside noise you hear inside.

Sometimes we need to extend the window reveal with some timber work, but that’s all part of the service.

Technical Information

Professional Quotation & Installation Process

Site Assessment: If required we start with a proper site visit to assess your windows, discuss your noise problems and take exact measurements. We may need to see the situation to give you accurate advice and pricing. A refundable consultation fee applies should you go ahead.

Custom Manufacturing: Everything is made to order for your specific windows. It takes a bit longer than off-the-shelf products, but it ensures a perfect fit and optimal performance.

Installation Services:

Window reveal extensions where needed for optimal air gaps
Careful installation to minimise disruption
Full cleanup and testing before we leave
We may be able to reinstall your blinds or curtains but not in all cases. This will be communicated to you at the time of assessment.

Double Glazing Energy Efficiency Benefits

Year-Round Savings

Winter Performance: Solar heat still gets through to warm your rooms, but the insulating air gap reduces that warmth from escaping back outside. Your heating system doesn’t have to work as hard to maintain comfortable temperatures.

Summer Performance: The thermal barrier works both ways – keeps hot air outside and cool air inside. Your air conditioning system will cycle less frequently, reducing energy consumption significantly.

Long-term Investment: The energy savings add up over time. For large commercial buildings, the annual savings can be substantial enough to justify the installation cost within a few years.

Comfort Improvements: No more cold spots near windows in winter or hot zones in summer. Much more comfortable living and working conditions year-round.

Reduced Condensation: Better thermal performance means less condensation forming on window surfaces. This protects your building materials and creates healthier indoor air quality.

Frequently Asked Questions

How much noise reduction will I actually get?

Our systems are independently tested and achieve Rw40-43dB noise reduction. In practical terms, you’ll notice a significant difference, especially with constant background noise like traffic. Most customers are surprised by how much quieter their homes become.

Can you retrofit any type of window?

We work with most window styles – sliding, double-hung, casement, and fixed windows. Occasionally we run into situations where it won’t work, but that’s rare. We’ll tell you straight up during the site visit if there’s a problem

Which acoustic window system should I choose?

Depends on your situation. Magnetic works well if you seldom open the window. Aluminium sliding is good for frequent opening and closing of windows for fresh air. We’ll recommend what makes sense for your needs.

How long does it take to install the acoustic windows?

A typical residential installation is a day depending on how many windows. Commercial projects vary widely – we’ll give you a realistic timeline during planning.

What warranty do you provide?

Yes, we warranty our work. Specific terms depend on which system you choose. All warranty details are included with your quotation so there are no surprises.

What happens to my existing blinds and curtains?

We will advise whether we can reposition them as part of the installation.

Will this work on heritage or older buildings?

Our retrofit systems are designed to preserve the external appearance of your existing windows. We regularly work with heritage requirements and council regulations. Happy to discuss specific heritage considerations.

How much maintenance is required?

Very little. Clean the panels like you would normal windows.

Customer Feedback

We just had our double glazed windows installed by Luca at Soundblock in our bedrooms and he was an absolutely pleasure to deal with. Very professional and friendly and the price quoted was very reasonable. Free measure and quote who they responded within 24 hours. Micheal came out and provided his honest opinion and was very transparent as we live on a busy road in Randwick. The service provided by Soundblock was second to none. I would definitely recommend Soundblock to family and friends. Well worth the investment with the difference in noise reduction.

Peter N

Very professional sound “sound” advice and service. We were kept informed of the progress of our order and the installers were extremely proficient and showed they enjoyed their work.
