Soundproof windows

Class 2:

• Reduces noise by 32 dB
• For buildings 50-100m from a suburban street (up to 100 vehicles per hour)
• For buildings 300m from an urban street (up to 500 vehicles per hour).

Class 3:

• Two glazings to reduce noise by 36 or 38 dB.
• 36 dB glass – for buildings 10-25 m from a suburban street, 50-100 m from an urban one, or 300 m from a major road (up to 1000 vehicles per hour).
• 38 dB glass –  for buildings 25 m from an urban street, 100 m from a major road, or 300 m from a motorway (up to 5000 vehicles per hour).

Class 4:

• Reduces noise by 42 dB.
• For buildings 10 m from urban streets, 50 m from a major one, 100 m from a motorway, or 300 m from train tracks.

Class 5: 

• Reduces noise by 45 dB.
• For buildings 25 m from a major road, 50 m from a motorway, 50-100 m from train tracks, or 300 m from an airport.

Compared to standard glazing, noise reduction glass used in soundproofing windows is been purpose-designed with special qualities to achieve specific classes.

Denser glass is used, for example, and the panes tend to be asymmetrical in their thickness to best reflect incoming sound from being transmitted through the window.

For classes 4 and above, so-called invisible "silence foil" is then manufactured into the glass, producing laminated glazing, which has the soundproof windows work at their maximum as effective noise reducing products.

Alongside the glazing, the window frame also plays a role in terms of window sound insulation. We offer a range of effective frame materials that can be combined with soundproof glass but uPVC or uPVC alu are the best natural insulators, for example.

They add an extra level of sound protection to the window and often feature built-in foam and mutiple chambers, which, especially when used to frame triple-glazed windows with purpose-designed glass, provide highly effective soundproofing.

• Thermal insulation

Due to the increased thickness of the glazing and inert gas filling between the double-glazed or triple-glazed window panes, the windows also effectively prevent energy loss and reduce the effects of conduction. Depending on the temperature difference between building interiors and exterior conditions, undesirable incoming or escaping heat is kept to a minimum, for example. This helps to maintain a comfortable interior temperature, which increases energy-efficiency and saves on utility costs.

• Break-in protection

Another advantage of soundproof windows is the enhanced break-in protection provided. The increased thickness of the glazing adds impact resistance, for example, and for glass of class 4 or 5, the inserted foil layer acts like laminated safety glazing.

The foil means that the glass is harder to break and reduces the likelihood that it will shatter out.

A further benefit of purchasing noise reduction windows from windows24.com is the wide scope for customisable design.

For those after a sleek, durable product, an aluminium frame can be selected, for example, while customers favouring a traditional style and bespoke pattern may prefer one of our wooden frames with a varnish coating. All frames can then be expertly finished in a quality RAL colour or timber decor of choice.

Many other add-on features are then also available. A smart home integrated window sensor can be selected for enhanced security, for instance, while matching roller shutters can be easily added to further combat noise pollution and perfectly complement new windows.

Just head to the configurator to make your choices today and purchase noise reducing windows without compromising on style.
