Acoustic Insulation

Noise pollution can have a significant impact on people’s health. Those living and working in cities are especially vulnerable, according to the World Health Organisation (WHO)1.

Controlling noise levels at the source is not always possible – but quality sound insulation of the building envelope can offer a valuable solution.

Outside noise from traffic or aircraft – for example – can be significantly blocked out by proper installation in the roof or building façade.

Insulation within a building, meanwhile, can improve privacy and avoid annoyance from sounds in adjacent properties, such as music or footsteps from an apartment above.

Especially useful when installed in separating floors and walls between different spaces in a block of flats or office complex, sound insulation products can be applied to reduce the amount of noise intruding into a living or working environment.

Why do we need acoustic insulation?

Noise affects health and wellbeing in many ways, from accelerating hearing loss to disrupting sleep and reducing productivity levels.

According to the WHO, around 40 percent of people aged 12 to 35 could be exposed to unsafe sound levels from entertainment venues2 - while noise from traffic in towns and cities is also cited as cause for concern3

Sound insulation can protect those living and working in buildings against exposure. Whether installed in the walls and floors at a major music venue, in busy offices or between urban living spaces, it can significantly reduce problems caused by nuisance noise.

Key benefits can include:

  • Protection from external noise
  • Comfort and privacy
  • Reduction of sound transmission and vibration passing through building elements
  • Applications for both renovation projects and new builds

 

How much do I need?

Building acoustics focus on sound transmission mainly through the building envelope (façade and roof), as well as internal walls, floors and ceilings.

The amount of acoustic insulation products required will depend on the material you choose, the size of the area being insulated and how much direct, flanking and other sound transmission there is.

  • Direct sound transmission – passes straight through the wall, ceiling or floor.
  • Flanking sound transmission – passes around, over the top or under the primary partition separating two spaces (passing through building elements adjoining the main separating elements).
  • Other sound transmission – leakage through poorly sealed doors and windows, brickwork and uninsulated pipelines.

From the airport Schönefeld, or passing cars, you hear almost nothing. And I’m also very confident for the upcoming BER air traffic.

Sustainability and energy efficiency

ROCKWOOL sound insulation is made from stone wool – a highly sustainable source that can be indefinitely recycled6.

When a building is renovated or demolished, it can be easily removed and recycled into new products, such is its level of circularity.
