How do acoustic timber windows and doors work?

Bereco acoustic timber windows and doors from the Ambient range reduce noise by absorbing sound waves causing them to lose power. This is achieved through, not only the glass but the frame itself, and each element is carefully designed to absorb and reflect pressure.

Acoustic Glass

Acoustic glass is made of two panes which have been laminated together using an acoustic membrane. This membrane absorbs the sound energy and prevents vibrations from travelling through the glass.

Dual Gasket

Using insulating double gaskets not only helps to reduce the amount of air leakage and weatherproofing but also helps to increase the window’s acoustic performance.

Engineered Timber

As the ultimate renewable material, timber wood is one of the oldest and most attractive. Plus, it has stronger sound dampening properties than most other window frame materials.

How do I identify the noise level I'm experiencing?

In modern life, we experience various types of environmental noise on a daily basis and the situation is getting worse. We may not even be aware of the damaging effect this has on our health and wellbeing. Take a look at the chart and use it to help identify and assess your current level of environmental noise exposure.

What sound reduction will I achieve?

The ratings we show represent the dB ratings for the overall window; frame and glass included. Not only this, we have acheived BlueSky certification for Noise Reducing Windows. This gives you a level of assurance that the sound reduction stated is the reduction you will experience.

Beautifully constructed windows which do the job perfectly. Handled Covid disruption effectively. Installation went smoothly. All in all a job very well done. Would recommend without reservation.


Visited the showroom last year and impressed with the finish and quality. Just as delighted with the windows and back door that we ordered. They look fabulous.
