The easiest point of entry for unwanted noise to enter your property, improving your windows is the best way to reduce noise pollution. At The Soundproofing Company we install top of the line metal and timber soundproof windows boasting reductions in noise of up to 51dB.

So whether it’s the clack of trains, the rumble of aircraft noise or simply the sounds of your street, we’re here to bring back peace and quiet, and improve the quality of life in your home.

Specialist Soundproof Windows

Letting heat out and sound in, traditional single and double glazed windows do very little to combat noise pollution from entering your property. However, through advanced designs, specialised glazing, acoustic sealants and flawless installation, modern sash and casement windows can deliver resounding reductions in unwanted noise whilst delivering superior energy efficiency at the same time.

The inner city favourite, our soundproof sash windows can offer a market-beating 47dB reduction in noise. Sleek, smooth and slimline we offer a heritage line and modern sash designs to both block out noise and maintain aesthetic.

Soundproof Casement Windows

Completely customisable to your property, our soundproof casement windows are elegant, durable and timeless. Constructed with ethically sourced, engineered timber and specialised glazing, we guarantee superior thermal efficiency and up to 51dB reductions in the Ultra range.

High Performance Soundproof Tilt & Turn Windows

Secured with a multi-point locking system, our tilt & turn soundproof windows open from the side and can be tilted down from the top for effective ventilation. With outstanding reductions in noise of up to 51dB and a triple glazing option, modernise your property and stop sound dead.

High Performance Secondary Windows

When noise is a serious concern, and you cannot change the visage of your house, secondary windows are for you. Sitting inside your existing frames, they work in conjunction with your current windows to offer a reduction of up to 55dB.

Windows and Sound

Your windows are considered the biggest weak point when it comes to sound entering your property, and are responsible for most noise complaints in the UK. This is because traditional windows, whether single or double glazed, are often constructed with very thin glass which will vibrate along with the frame.

Non-specialised windows will also have ‘coincidence frequency’ (also known as a critical frequency) – a frequency at which the windows will act as perfect conductors for noises in a certain range, and can even amplify the sound. If this frequency coincides with the major source of your complaint you will experience considerable levels of noise in your home.

It is also worth noting that sound will travel through the path of least resistance. If the windows have been inappropriately installed there could be air gaps around the frame or glazing, which will allow sound to flood into the property.

Types of Noise

Tackling noise pollution requires a considered approach and an understanding of the source of the complaint. This is because each source generally fits between certain frequency ranges depending upon your proximity to it.

The most common issues in the UK are from:

Aircraft Noise

The noise you experience will depend on how close you are to the flightpath, whether the planes are landing or taking off, the type of aircraft…


Road Traffic Noise

A sidestreet home on the morning commute route, complete with speed bumps differs from the constant roar of a nearby motorway, which is different to an A road…


Train Noise

The noise you experience from trains will depend upon which train line you’re near, whether the train is coming around a corner, if it’s freight or commercial…


Anti-Social Noise

Anti-social noise takes many forms. From the neighbour’s dog barking in the morning, to the thump of a nearby club, or simply pedestrians passing by…


How Soundproof Windows Combat Noise Complaints

Working against the coincidence frequency and dampening and dissipating the wave, soundproof windows employ the following design features to reduce noise pollution:

Specialised Glazing

The thickness of specialised soundproof glazing used will depend upon the noise reduction requirements, with glass of two different thicknesses employed to work against the coincidence frequency.


The panes in a soundproof windows are laminated with a layer of polyvinyl butyral (PVB) which reduces the elasticity of the glass, helping dampen the sound.

Acoustic Sealant

High performance acoustic sealants plug any gaps in the frame design to ensure noise cannot skirt around the frame.

Acoustic Foams

During installation acoustic foams are used to ensure that noise cannot be transmitted between the wall and the window.

Dampened Sash Boxes

The boxes which house the sash’s opening mechanism have been modified to include acoustic dampening materials.

Remember, soundproofing your home is only as effective as your weakest link. If you’re suffering from noise pollution and are considering soundproofing windows in your property, you may also want to consider:
