Acoustic Windows

There has always been a great debate in the windows and doors industry about the best way to reduce noise from entering our homes. We know that many customers and potential customers of ours ask about the best way to cut down on noise from external sources in order to make their homes quieter and more comfortable to live in!

If you live near any sources of noise, such as busy roads, airports or even have noisy neighbours, you will know how disruptive it can be to suffer from excess noise. Acoustic windows can help reduce external noise entering your home, but the right solution depends on the type of noise, the existing window and the glazing system selected. Finesse Windows' Shield Protection glass provides a further 20% reduction in decibel levels compared with a standard A-rated sealed unit.

Noise Reduction Windows

How much noise do acoustic windows actually block?

Finesse Windows' Shield Protection glass provides a further 20% reduction in decibel levels compared with a standard A-rated sealed unit. This is a relative improvement rather than a claim of a specific overall dB reduction, because the noise entering a home depends on the complete window, installation and external noise source. Noisy neighbours, barking dogs, and the continual drone of traffic noise & emergency service sirens are all common culprits when it comes to disturbing our peace and quiet.

The Noise Reduction glass solution, Shield Protection glass, from Finesse Windows is proven to provide a further 20% reduction in decibel levels compared to standard A-rated sealed units, alongside its enhanced security and UV protection benefits.

Finesse Windows worked with GlassSolutions Saint-Gobain to develop this complete sealed-unit solution. The specification combines a laminated inner pane with a PVB interlayer and other specialist glazing components to help reduce external noise. Saint-Gobain also identifies acoustic PVB laminated glass as a glazing solution designed to reduce noise.

Acoustic Glass FAQS

Noise pollution is a big problem, especially in busy towns and cities.  Triple glazing can have some success in reducing noise, however because it is produced with an extra layer of glass, it can end up just exacerbating the vibrations from external noise!

Our special acoustic glass is made up of 3 parts – 2 layers of glass which sandwich a layer of PVB (Polyvinyl Butyral) which really helps to minimise external noise.

Acoustic glass is a specialist glass sealed unit which is fitted into a window profile/frame which is designed to reduce external noise pollution.

At Finesse Windows we worked with GlassSolutions Saint Gobain to develop Shield Glass Units, with the goal to give unrivalled performance for your home in noise reduction but also in security and uv resistance.

In tests, Acoustic double-glazed windows made by Finesse Windows have been found to provide a further 20% reduction in Decibel levels compared to a standard A-rated seal unit.

However, even with the adding of noise reducing glass it is vital to ensure that the window in its entirety is also fitted correct by MTC accredited fitters who are regularly inspected by FENSA.

Yes, when it comes to soundproofing your home. Soundwaves are reflected, absorbed, and dampened by acoustic glass whereas triple glazing is designed to improve energy efficiency. Triple glazing, on the other hand, may even boost noise in your house by generating an echo chamber and amplifying the sound through vibration.

Acoustic glass, unlike traditional glass, is not only suitable for noise reduction, but also improves the safety of your home. In controlled tests, when comparing our ‘Shield Protection’ A Rated Acoustic glass sealed unit against a Standard A Rated glass sealed unit, it took an intruder 18x longer to gain access with the Shield Protection sealed units. Shield Acoustic glass also offers up to 99% protection from the Suns harmful UV rays.

Acoustic glass comes in a variety of thicknesses. Our Acoustic Glass is made up of 2 x 3mm Paniclear pane laminated with a 0.8mm PVB interlayer, coated with Planitherm Total+ coating on the surface on the inside, with a 18mm Swiss spacer with Argon Gas Fillm sealed with a 4mm Diamant Toughened Safety Glass.

Accoustic Windows to Reduce Noise

Will acoustic glass stop traffic noise from a main road?

Acoustic glass can reduce traffic noise entering a home, but there is no single dB figure that applies to every installation. Finesse Windows' Shield Protection glass provides a further 20% reduction in decibel levels compared with a standard A-rated sealed unit, while the final result also depends on the window, frame, installation and building. Many people think that you can reduce noise from outside by adding an extra glazing layer to your glazed windows. Adding another glazing layer can be effective in some situations, but the most suitable approach depends on the existing window and the property. The best solution should consider the complete window system rather than looking at the glass alone.
Shield Protection glass is a complete double-glazed sealed unit incorporating a PVB interlayer between two panes of glass. Finesse Windows developed the solution with GlassSolutions Saint-Gobain, combining specialist glazing components to help interrupt and reduce the transmission of external sound. For homes affected by road traffic, airports or other persistent external noise, the existing window, frame, ventilation and installation should all be assessed before choosing a glazing solution. Government guidance also recognises acoustic glazing and sound insulation as measures used for properties affected by significant road noise.

The best solution to your noise problem at home is to use our special acoustic glass. This is a double-glazed unit which sandwiches a special layer of PVB (Polyvinyl Butyral) in between two layers of glass. This combined with an optimised frame design fitted by our skilled team, combines to interrupt the soundwave and this reduces the decibel levels. Our Shield Protection sound reduction glass windows will provide a further 20% reduction in decibel levels compared to A-rated sealed unit.

Acoustic double glazing or secondary glazing – which is better?

There is no single best option for every property. Acoustic double glazing is a practical choice when replacing the existing window, while secondary glazing can be particularly useful where the original window needs to remain in place, including some historic and listed buildings. There are always lots of technological advances coming out in the glass industry with claims that they can perform in a certain way, however here at Finesse Windows, we prefer to gain our own supporting evidence from our happy customers – for this reason, we highly recommend the acoustic glass for customers seeking a good noise reduction in their homes.
Secondary glazing adds a separate glazed system behind the existing window rather than replacing the original window. It can provide sound insulation while retaining an existing window, and it is recognised as an option for improving the acoustic performance of historic windows. Listed-building guidance from UK local authorities also identifies secondary glazing as a potential solution where preserving existing windows is important. We offer our special acoustic glazing for doors and windows to suit your home style and can create custom windows to work the way you want them to. If you are unsure whether acoustic double glazing or secondary glazing is more suitable, our team can assess your existing windows and advise on the most appropriate solution for your home.
