Secondary Glazing Noise Reduction Windows: What They Are and The Benefits of Having Them

If you’re looking for a way to reduce noise in your home, you may want to consider secondary glazing for your windows. This type of window is designed to help block out sound from the outside, making it a great option for people who live in noisy neighbourhoods or who have trouble sleeping because of noise. In this article, we will discuss what secondary glazing noise reduction windows are, how they work and the benefits of having them!

What is secondary glazing and how does it work?

Secondary glazing (also known as secondary windows) is an additional window that is installed inside an existing window frame. It is often used to improve the energy efficiency of a home or to reduce noise levels from outside.

Secondary glazing can be either fixed or operable, and it is usually made of clear acoustic glass in order to maintain the original appearance of the window. When installed properly, secondary glazing can be virtually invisible from the outside and practically maintenance-free.

In addition to being an effective way to improve energy efficiency, secondary glazing can also make a significant difference in reducing noise pollution. By creating an additional barrier between the inside of a home and the outside world, secondary windows can help to reduce unwanted noise by up to 50%. As a result, it is an ideal solution for people who live in noisy urban areas or who are sensitive to sound.

Secondary Glazing Noise Reduction Windows Being Installed

How does secondary glazing reduce noise pollution?

There are a few key ways that secondary glazing windows help to decrease noise pollution. One is by acting as an extra barrier between the outside world and your home. If you live on a busy street, for example, secondary windows can help to muffle some of the traffic and external noise and has been said to help reduce noise levels by up to 50% because of the sound insulation it provides.

Another way that secondary windows helps to reduce noise pollution is by absorbing sound. The extra layer of glass and the gap between the two panes help to absorb sound waves, making them less likely to reach your ears.

Finally, secondary glazing can also help to block out low frequency sounds, like the rumble of an airplane engine. This is because the extra layer of glass helps to reflect these low frequency sound waves away from your home.

What are soundproof windows?

Very similar to secondary glazing solutions, soundproof windows are also designed to reduce noise pollution. The main difference between the two is that soundproof windows are usually installed in new construction homes or during a renovation, while secondary glazing can be added to an existing window.

Soundproof windows are made with thicker panes of glass and often have a sealant around the perimeter to create a tighter seal. This provides acoustic insulation and helps to block out more noise than a secondary glazing window and is an ideal solution for people who are looking for complete peace and quiet.

If you are in an area that does suffer from a significant amount of noise pollution, it can also be worth looking at soundproof secondary windows.

What are the other benefits of secondary glazing?

Energy efficiency:

One major benefit is that it can be used to improve the energy efficiency of a home. For instance, it can help to reduce heat loss in a building by up to 60%, making it an extremely effective way to increase energy efficiency and keep your heating bills down during those winter months.

Additional protection:

Secondary glazing can also provide protection from ultraviolet (UV) radiation, dust, and other pollution. This is because the extra layer of glass helps to filter out these harmful particles, making it a great option for people who suffer from allergies or respiratory problems.

Better aesthetic:

It can be an attractive way to decorate a room, as it allows for a variety of different styles and colours. secondary glazing is an ideal solution for those who want to improve the energy efficiency and comfort of their home without compromising on style.

Security:

Finally, secondary windows can also help to improve security. The additional window acts as a barrier that makes it more difficult for intruders to break into your home.

While it is more expensive than primary glazing (though cheaper than secondary), it can be well worth the investment for those who live in areas with high levels of traffic noise or poor air quality.

Secondary Window for Noise Reduction

Can you add secondary glazing to existing windows?

In short, yes.

Secondary glazing actually work by adding a second window to the inside of your existing primary window. This can be done to most types of windows, including sash, casement, tilt and turn, and bay windows.

If you’re looking at replacing your current windows and install secondary glazing, you can actually save money in the long run by installing double glazed windows that come with secondary glazing built-in, this is sometime referred to as secondary double glazing.

How does installing secondary glazing work?

The process of installing secondary glazing is actually quite straightforward. First, a surveyor will come to your home to take measurements of your existing windows. They will then create a bespoke frame that will be fitted to the inside of your window.

Once the frame has been fitted, they will add the second window (or glazing panel) and make sure that it is sealed properly. Finally, they will add any finishing touches, like trims or handles, to complete the look.

How is secondary glazing different to double glazing or triple glazing?

You might be wondering how secondary glazing is different to double or triple glazing. The main difference is that secondary glazing is added to an existing window, whereas double and triple glazing are installed as part of a new window.

When it comes to insulation and noise, windows are one of the biggest culprits for letting out the eat and the noise in. Double glazing is a common solution for these, as it involves installing two layers of glass in the window frame.

However, double glazing can be expensive, and it isn’t always possible to retrofit it into existing buildings. Secondary glazing is a cheaper and more flexible option, as it involves fitting a second window frame on the inside of the existing one. This creates an air gap between the two frames, which helps to reduce heat loss and adds an additional barrier that muffles noise.

Triple glazing is another option, but it is even more expensive than double glazing and isn’t always necessary in milder climates. Triple glazing is certainly more effective at blocking sound than double glazing, but can be comparable to secondary glazing in this regard. The major benefit of triple glazing over secondary, is that it’s a lot more effective as a form for insulation.

Ultimately, the best solution depends on the climate, the type of building and the budget. However, secondary glazing is definitely worth considering as it offers a cheaper and more flexible solution than double or triple glazing.

What glazing is best for noise reduction?

So, we’ve looked at secondary glazing as well as discussed double and triple glazing, but what glazing is actually best for noise reduction?

The answer, as you might have guessed, depends on the specific situation. In general, though, thicker glass and air gaps are better at reducing noise. This is because they help to reflect sound waves away from the window and prevent them from entering the building.

However, in some cases, such as when dealing with low frequency noise, secondary glazing can actually be more effective than double or triple glazing. This is because the air gap between the two windows acts as a barrier that muffles sound.

So, there is no definitive answer when it comes to the best type of glazing for noise reduction. It really depends on the specific situation and what type of noise you are trying to reduce, as well of course on your budget and how much you are looking to spend.

How much does secondary glazing cost?

As we’ve seen, secondary glazing can be a great way to improve energy efficiency and improve sound insulation. But how much does it actually cost?

The cost of secondary glazing will depend on a number of factors, such as the size of the window, the type of frame and the number of windows you are looking to install.

In general, though, you can expect to pay between £100 and £300 per square metre (including labour). This means that a typical secondary glazing project with new or replacement windows will cost between £500 and £1000.

Of course, this is just a rough guide and the actual cost will depend on the specific circumstances of your project and the secondary glazing unit you choose. However, it is clear that secondary glazing is a relatively cheap way to improve the energy efficiency and sound insulation of your home.

Conclusion:

We hope this article has helped breakdown what secondary glazing is and how it can be extremely helpful in noise reduction when added to existing windows. You of course also have the options of double glazing and triple glazing when looking for soundproof windows, and which one you choose will be down to you.
