Best Ways To Reduce Outside Noise In Your Home

Share this post


Anyone living in London will know that it suffers from the same problem as any bustling metropolis.


Between cars, airplanes overhead and the general commotion of a city that is home to over 8 million people, it can be hard to get peace and quiet.

In fact there is even evidence to suggest that high noise levels can have an adverse effect on your health.

This is why many people now look for noise reduction windows in London to drown out the sound outside.

First Stepsheat loss through windows

Changing to noise reduction windows is a great way to get rid of outside noise but there are some other steps you can take to help with this.

Open chimneys, doors and windows with gaps are the main culprits and sealing up an open chimney (if it is safe) can do wonders for reducing noise. Even using draught excluders and caulking to seal gaps is an effective to keep unwanted noise outside.

You should go around every room in your home and identify the reasons why the noise is coming in. While soundproof windows or secondary glazing is usually a good way to soundproof your home if the frames aren’t sealed properly and there are other air gaps - the noise will still get in.

Sealing up gaskets, caulks and the space around your windows frames is a good first step to a quieter home.

A good rule to follow is: if air can get in, then sound can too! So by sealing up door frames, window frames and even around electrical outlets and cable channels, you can reduce the outside noise.

Soundproof Windows

If you are really serious about stopping the London noise getting into your home then soundproof windows win every time.

These noise reduction windows are made specifically to lower the amount of decibels that you hear inside your property.  The problem is that they can be both expensive and require a complete replacement of your windows and frames.

Soundproof windows work by both absorbing the noise and also reflecting it back and away from the inside of your property.

If you are having significant trouble with the noise in your home and you don’t mind a bit of upheaval to your property then these are the best windows for noise reduction.

Secondary Glazing

On the other hand using secondary glazing can minimise the amount of work needed while also providing a good level of noise protection.

This system works by simply installing another window frame and glass panel to provide an extra layer of protection.

Usually the second layer of glass is thicker and will absorb more sound than your original window as this reduces what is known as sympathetic resonance which is noise transmission at a higher frequency. This option is frequently installed in conservation areas, where existing window can not be changed. The original window is kept and the secondary glazing added on the inside.

While this option provides good noise reduction, it will not be as effective as soundproof windows - although it is a more budget friendly measure that doesn’t require as much work.

Effects of Glass and Airspacetriple glazed window

While double or triple glazing can really eliminate unwanted outside noise, a lot depends on the frames and seals. Even the effect of triple glazed windows can be significantly decreased if they are not designed properly.

Having too little space between each pane results in more noise filtering through due to less airspace. In fact, a larger cavity will reduce outside noise and installing window panes with varied glass thickness provide better noise reduction than a uniform design.

Acoustic laminate glass works particularly well for high frequency sound by being more absorbent and using this type of glass on double glazed windows can reduce noise intrusion by up to 50%.

Both Options Provide Excellent Draught Proofing

If you are weighing up the different options of having noise control glass in your home then you will be happy to know that both come with great draught proofing and thermal efficiency.

Old and poorly designed windows with wooden frames are the main culprits when it comes to lower energy efficiency levels. In fact windows regularly cause heat loss that not only makes the property feel cold but costs money too.

Sound proofing windows works best for draught proofing as they are designed to not only keep noise out but keep everything else (including heat) in.

Secondary glazing does this as well. As it creates another barrier between your home and the outside world it reduces heat loss and keeps cold air at bay – although not to the same effect as soundproof windows.

Fixing leaks and draught areas can help with soundproofing but it won’t have the same result as noise reduction windows.  While heat insulation measures do offer some soundproofing they both have different objectives. Using the two together with well-designed soundproof windows, will really make a difference to your home.

Which Windows Are For Me?

This really depends on your budget and status of your home.

Secondary glazing offers good noise reduction at a cheaper price and they are easier to install. Soundproof windows provide almost complete noise reduction but are more expensive, need more work to install and often require planning permission.
