The acoustic insulation of timber windows: how to reduce noise pollution

Fitting high-performance glazing is not enough: timber windows afford optimal acoustic insulation precisely because this material, unlike plastic and PVC, is much better at absorbing outside noise. The acoustic performance of these  windows is of the highest standard.

Timber windows and acoustic insulation: a perfect combination

To guarantee high acoustic performance of windows, the choice of material is of fundamental importance: wood achieves the highest results

The question of the acoustic performance of a window in a dwelling is of fundamental importance, especially given the increase in high density building in our cities and towns: the ability of a window to dampen outside sounds and keep out noise pollution is one of the key conditions to guaranteeing the well-being of its occupants – and that they get a good night's sleep.
In this sense, timber windows guarantee a truly optimal acoustic insulation, since noise is absorbed by the window frame as well as by the glazing. This is a key aspect, to be taken into due consideration when rating the acoustic performance of a window.

Acoustic performance of the window or only of the glazing?

A key point when addressing acoustic performance is whether we are considering the whole window or just the glazing

A timber window can achieve an overall sound reduction of 42 decibels and more, a rating which is often impossible for windows made of other materials such as PVC or aluminum. In this sense, we need to pay close attention to a detail that can really make a huge difference: certifications often apply to the acoustic performance of the glazing alone, and not of the whole window

 The acoustic performance of a window as a whole is very different from that of glazing: this is why a timber window guarantees truly optimal acoustic insulation 

For instance, a glass window mounted onto a PVC window will not maintain its performance: when it comes to the acoustic insulation of timber windows, the choice of materials makes the difference. PVC and aluminum windows feature hollow-chamber frames, so the sound waves do not bounce off and are free to penetrate the house. Timber frames, by contrat, have a full mass chamber and are capable of dampening sound waves and absorbing noise.

What are the best timber windows for acoustic insulation?

The acoustic insulation of timber windows is therefore optimal: but are all wood varieties the same or do some guarantee better performance?

As we have said, whereas timber windows achieve optimal levels of acoustic insulation, there are clearly natural differences from wood to wood. As we have seen, the acoustic performance of a material depends on its ability to interfere with the propagation of sound waves, reducing the strength of reflected noise. This is why timber windows will achieve far better acoustic ratings compared to window frames made with harder woods. In any case, they provide outstanding levels of soundproofing that makes them perfect for problematic locations where noise levels are unacceptably high.
