Less noise pollution
Low energy buildings have tight constructions which not only reduce the energy consumption, but also reduce the noise from traffic and other sources that would otherwise penetrate into the building.
Every day - and night - millions of people around the world are suffering from unwanted sound. Noise causes stress, loss of concentration and affects well being. It can provoke stress-related heart problems and can have severe negative social and economic impact. Some 120 million people have disabling hearing problems, according to the World Health Organisation.
Lack of sound proofing not only makes life miserable for people living next to noisy neighbours, it also prevents many of us from free expression of music and other happy, yet noisy, activities.
Prevention of noise pollution
The elements of a healthy building must
- Reduce noise reverberating inside a room
- Impede transmission between rooms
- Prevent noise from the outside penetrating the building

Insulation helps to reduce noise
Rockwool stone wool has an open fibrous structure making it ideal for absorbing and regulating noise. Rockwool systems and products reduce noise from machines or from the activities of people. Our Rockfon acoustic ceiling systems can dramatically reduce sound reverberation and prevent echoes in a room. Façade insulation, NoiStop noise fences alongside roads and RockDelta vibration insulation under rail tracks abate frustrating traffic noise.
Noise affects 40 % of EU citizens and can reduce the value of property by 1.6 % for every decibel above 55dB.
Additionally, buildings that have Rockwool insulation in walls, roofs, around machines and under floors often do not let much noise out or in. That is because noise from or to the neighbours and from outdoor is effectively dampened through the open fibrous structure in the stone wool.
A 10dB difference is perceived by the human ear as a doubling (or halving) of the audible sound. A good wall construction with Rockwool insulation can help ensure many a good night’s sleep. It can reduce noise transmission by more than 50dB (RW- value) which is about 20dB more than a poor construction without insulation.
