Noise pollution is a constant issue in busy cities like London, with the sounds of traffic, construction, and city life easily invading your home. But the design of your property plays a key role in reducing this noise – and your windows are the most important place to start.
In this post, we’ll explore exactly how sash windows can help create a quieter home in the heart of the big city.
The Inevitable Noises of Urban Life

Traffic is one of the most persistent sources of noise pollution, with the sounds of engines, horns, and sirens creating a near-constant background hum. Construction work adds another layer of noise, from the early hours of the morning until late afternoon.
And this is all without the nightlife in certain areas – where bars, clubs, and restaurants extend noise levels well into the night.
Studies have shown that prolonged exposure to high noise levels can lead to a range of health issues, including stress, sleep disturbances, and even cardiovascular problems. Reducing noise pollution in the home is essential for improving overall well-being.
Modern sash windows can help reduce noise pollution, though their sliding design means some inherent movement between the sashes. A well-fitted sash window with quality seals can minimize external noise, but may not achieve as tight a seal as other styles. For greater noise reduction, options like acoustic glass or secondary glazing may be needed.
The Proof Is in the Glazing
Double-glazed units consist of two panes of glass separated by a spacer to create a gap, which is usually filled with air or an inert gas like argon or krypton. This gap is an insulation barrier, improving thermal efficiency and reducing noise transmission.
If replacing your windows isn’t an option, secondary glazing can be an effective alternative for reducing unwanted noise.

What is Secondary Glazing?
Secondary glazing is an effective method for improving the noise insulation of existing windows without the need for full replacement. It involves installing an additional pane of glass on the inside of the existing window frame, creating a secondary barrier against sound.
One other major advantage of secondary glazing is its cost-effectiveness. For homes in conservation areas or those with listed status, where replacing original sash windows might not be an option, secondary glazing offers a viable alternative. It allows you to retain the aesthetic and historical value of your original windows while gaining all the modern benefits.
Secondary glazing is also far less disruptive to install compared to a full window replacement. It can be customised to fit any window shape and style, making it a flexible solution for a wide range of properties.
Is Secondary Glazing Suitable for All Windows?
Secondary glazing can be added to almost any type of sash window, including both traditional timber and modern uPVC designs. It is a versatile solution that can be customised to fit the specific dimensions and style of your existing windows, making it an ideal choice for listed buildings or conservation areas where window replacement is not an option.
Will Secondary Glazing Affect the Appearance of Sash Windows?
Secondary glazing is designed to be as unobtrusive as possible. It is installed on the inside of your existing windows, so it doesn’t alter the external appearance of your property.
How Does Secondary Glazing Compare to Full Window Replacement?
Secondary glazing is generally more cost-effective than full window replacement, making it an attractive option for homeowners on a budget. It offers substantial noise reduction and thermal efficiency improvements, similar to what you might achieve with double glazing, but without the higher costs and disruption associated with replacing your windows entirely.

Extra Tips for Reducing Noise in the Meantime
While upgrading your windows is one of the most effective ways to reduce noise pollution, there are several other strategies you can implement to create a quieter home. Here are some additional methods to consider:
Heavy Curtains or Drapes

Thick, heavy curtains can help absorb sound and reduce the amount of noise entering through windows. Consider using curtains with a dense fabric or adding a thermal lining to existing curtains for better noise reduction. This is a quick and affordable solution that can complement other noise-reducing measures.
Rugs and Carpets

Hard floors can amplify noise, especially in multi-story homes. Laying down rugs or carpets helps absorb sound and reduces the overall noise level in your home. If you’re dealing with noise from neighbors, placing rugs on the floor above the source of the noise can help dampen the sound.
5. Seal Any Gaps and Cracks

Noise can find its way through even the smallest gaps and cracks in your walls, floors, and ceilings. Please take the time to look over your home and seal any gaps. This is a cost-effective way to reduce noise and improve insulation.
These methods, when combined with upgraded windows and doors, can significantly reduce the level of noise pollution in your home.
