Stop Noise's Double Glazed Glass Services — The Ultimate Solution for Comfort and Quiet
Welcome to Stop Noise, your go-to source for cutting-edge double glazed glass solutions. Our mission is to transform your residential or commercial areas into zones of tranquillity and energy efficiency. Specialising in customised double glazing glass services, we are committed to adapting our solutions to meet your distinct needs.
What Is Retrofit Double Glazing?
Thinking about double glazing? Retrofit double glazing is a clever and cost-effective way to upgrade your home’s comfort. Instead of tearing out your entire window, we add a second, custom-made pane of glass to the inside of your existing window frame. It’s a simple, brilliant upgrade.
This process allows you to double glaze existing windows with minimal fuss, creating a powerful insulating barrier. Our system of retrofit double glazed windows is designed to deliver maximum performance, giving you all the benefits of double glazing without the cost and disruption of a full replacement.
How Retrofit Double Glazing Works
Our approach to retrofitting double glazed windows is based on proven acoustic science. By adding a secondary window, we create a substantial air gap between the new pane and your original glass. This gap is the secret to its success, acting as a buffer that dramatically reduces noise and improves thermal performance.
This method of soundproofing and window insulation is far more effective than standard replacement units because the wider air gap (typically 70-100mm) is superior at dampening sound waves and preventing heat transfer. It’s a straightforward way to double glaze existing windows for a quieter, more comfortable home.
Replacement Vs Retrofit Double Glazing — What’s the Difference?
Before you consider a full window replacement, see how our retrofit double glazing stacks up. The choice is clear:
Keep your original windows and cut the cost in half. The retrofit windows cost is significantly less than a full replacement.
We add a discreet second pane to your existing frames. No ripping them out, no dust, and no need to re-plaster or repaint.
Our process is quick and mess-free, respecting your home and your time with minimal disruption.
Our system blends seamlessly, maintaining your home’s original character. It’s the perfect, body-corporate-friendly solution for apartments.
You get better results for a lower double glazed cost and none of the hassle. That’s the Stop Noise promise.
How a Double Glazing System Really Works
If your property already has existing windows, our double glazing system can be seamlessly retrofitted without the need for full replacement.
We install a secondary glass panel onto your current window frame, creating an insulating layer that significantly reduces cold draughts and prevents heat from escaping during the winter. This upgrade helps maintain a more consistent and comfortable indoor temperature year-round.
At Stop Noise, we keep costs down by using your existing glass and adding a second pane—separated by a wide air gap. This gap acts as a powerful insulator, reducing both external noise and temperature transfer to improve your home’s comfort and energy efficiency.
Our double glazing system is compatible with timber, steel, and aluminium window frames.
Unlike full window replacements, we don’t remove your existing glass. Instead, we retrofit our secondary glazing system directly onto your current windows, making the process simple, efficient, and non-intrusive.
For aluminium windows, we take precise measurements and custom-manufacture the secondary glass panels at our Melbourne facility. The new pane is installed behind the original single-glazed glass, allowing you to retain your existing windows while gaining all the benefits of double glazing. This makes it a cost-effective and low-disruption solution.
By upgrading to double glazing, your home stays more comfortable year-round—especially during Melbourne’s cold winters—providing better insulation and a noticeably cosier indoor environment.
How Window Double Glazing Makes a Difference in Your Home
Single-pane glass provides very little insulation. Because glass is a strong conductor of heat, the warmth inside your home can easily escape—especially during colder months.
By installing double glazing on your existing windows, you introduce an insulating air gap between two panes of glass. This layer of air acts as a thermal barrier, slowing down the transfer of heat and helping to retain warmth inside. Since air is a poor conductor of heat, this setup significantly improves your home’s energy efficiency and comfort all year round.
How Much Does It Cost to Double Glaze Existing Windows?
This is one of the most common questions we’re asked—and the answer depends on several factors, including the type of glazing system you choose.
A full window replacement, which involves removing the existing window and installing a completely new double-glazed unit, typically costs between $1,200 and $1,500 per square metre, fully installed.
In comparison, our secondary glazing system, which is added to your existing windows, ranges from $600 to $800 per square metre. This makes it a significantly more affordable and less disruptive alternative.
If you’re looking for a cost-effective way to reduce noise, improve insulation, or enhance safety—without undergoing a full window replacement—secondary double glazing is the ideal solution.

Benefits of a double glazing window system
There are many advantages of installing a double glazing window system for your home and your family as well.
Incredible insulation
As we’ve said above, glass is a conductor of heat which means it can do an excellent job of keeping heat out in the wrong time of year and letting it in when you don’t need it. So with double glazing, you’re keeping your home at the right temperature all year round.
Safeguard your furnishings
Did you know that intense heat inside your home can damage the furnishings? Such as deterioration of furniture, curtains and other materials inside a home. Control extreme heat from doing this and protect your furniture and furnishings for longer.
Increase the value of your home
Having these windows in your home increases the value of your property because of the above benefits. Having a home that is going to maintain a comfortable temperature, have reduced sounds coming in, and higher safety will increase the selling features of your home.
Reduce sounds
If you’re like most people, then you’ll know that noise interferes with sleep. Which means you’ll suffer consequences such as headaches, irritability, stress and on-going fatigue. If you find yourself suffering due to noise entering your home, then our window system will help to create a healthier environment inside your home. Double glazing windows create an incredible form of soundproofing that reduces noise levels by 50 to 70%.
Improved energy efficiency want to reduce your energy bills and save money? If so then double glazing windows create an energy-efficient house because you won’t need to use as much electricity with heating in the winter and cooling in the summer. The fantastic double insulation that double glazed windows create means your home stays at a comfortable temperature all year round.
Increased protection
At Stop Noise we’re sure you want the best safety and security for your home and your family too. If so then double glazing your windows will help to do this. A double glazing window system makes windows incredibly challenging to smash, break and forcibly open. This difficulty is both from the inside and the outside of the glass. Which means less cracking and splitting from inside your home and deterring people who may try to break the glass from the outside if they are attempting a break-in. Which means increased safety inside and outside your house.
Having this air space between the windows is how maximum noise reduction and insulation is achieved.
