Noise can be a nightmare! This is why glazing with sound insulation is sometimes necessary to find calm and serenity. Acoustic insulation techniques have the advantage of adding other qualities to your windows such as better thermal insulation and greater security.

The different glazing "noise canceling"

Everyone had a day or two to endure a disturbing noise like a jackhammer, the barking of a dog, the road traffic... and we know how much it can be disturbing, tiring, stressful or even harmful for the health. Glazing with sound insulation can reduce and even stop most of these inconveniences.

The loudness is calculated in dB (decibel) and the sound insulation performance of a glazing is measured in Rw.

The double and triple glazing is a very good sound insulation but there are even more powerful models. They are either asymmetrical double glazing made of glass panels of different thicknesses (10mm on the outside and 4mm on the inside), or the combination of a single glass and a laminated glass with a space between the two filled with an insulating gas such as argon for example. Laminated glass enhances sound insulation thanks to PVB (polyvinyl butyral) spacers.

With each sound, a suitable glass!

Each person has a personal level of tolerance against noise but some conditions are more or less bearable.

Generally, in the countryside and in quiet areas, windows without special sound insulation may suffice. But in some cases, the outside noises can become invasive: trade, building site, plane, car, discotheque, metro... To find the calm at home, it is necessary to choose the good glazing.

There are classifications to help you make the right choice, such as:

  • CEKAL certification is given by an independent and impartial organization that guarantees your windows for ten years and allows to know the level of performance of the windows in six categories. For example, the class AR1 reduces noise by 25 to 28 dB and the last class AR6 up to 37 dB.
  • Acotherm certification ensures the acoustic performance of glazing and joinery, which are rated AC1 for simple AC4 insulation for reinforced insulation.

All the benefits of glazing with sound insulation

In addition to the reduction of external noise, the sound insulation of a glazing leads to other advantages that are associated with the quality of the glass. It reinforces the thermal insulation and resists shocks thus delaying break-ins. It can also be associated with windows to control the sun's UV, humidity or self-cleaning systems.

In any case, it is recommended to seek advice from a competent specialist who can refer you to the best solution to take.
