acoustic insulation, silence, soundproof

Acoustic wall insulation helps reduce sound transfer through both internal in external walls residential and commercial properties, in order to enrich modern living.

It promotes comfort and privacy, protecting people from ‘outside-to-inside’ noise such as traffic, and ‘inside-to-inside’ noise from neighbouring dwellings.

For many years noise has been considered a ‘pollutant’, potentially causing psychological and other health effects. Our solutions can effectively reduce its impact on your building or project.

We offer a range of applications:

  • Partition walls – stud walls separating spaces within a property.
  • Party walls – cavity walls, plasterboard walls, lining on base wall; offering protection between dwellings. 
  • Cladded and ETICS Façade – insulation installed in façade systems with external (ETICS) or internal lining.

Why do we need acoustic wall insulation?

Quality, properly installed acoustic wall insulation can greatly limit noise transfer – from the outside environment, between properties and even within the same office or domestic space.

Unwanted noise entering homes from the outside environment and adjacent dwellings can cause sleep disturbance, potentially leading to other health risks. Acoustic wall systems lower the levels of noise exposure to create a more comfortable living environment.

Healthier buildings can have a positive impact on office workers too. Reducing the impact of outside noise and loud neighbouring offices may improve productivity and employee health1.  

Key benefits of our insulation include:

  • Protection against internal and external noise
  • Easy to install across different systems
  • Enriched modern living, through enhanced comfort and privacy

Calculator and savings

The amount of insulation required will depend on the type of wall, its surface area and the thickness of the cavity being insulated – where relevant. 

With acoustic insulation for stud walls, measure the wall size for an indication of how much you need, choosing a density that suits your soundproofing requirements and the size of the gap.

When insulating a cavity wall, measure the gap and wall size for the best indication of how much insulation you need.  

Use our ROCKWOOL RT60 Calculator to determine the acoustic performance of the building’s walls, and estimate the acoustic delay value (echo). For more details on technical specifications, visit our ROCKSPEC Specification Toolkit.

By introducing sound-absorbing material to fill the cavity, it is possible to mitigate the effect of cavity resonance that badly affects the acoustic performance of the wall.

Sustainability and energy efficiency

ROCKWOOL products can be indefinitely recycled, helping create a circular business model5. They are all designed to last the lifetime of a building, reducing building waste and forming highly sustainable solutions.

Acoustic wall insulation helps promote indoor comfort – and reduces exposure to noise pollution.  

Thanks to stone wool’s thermal properties, it can naturally improve a building’s energy efficiency too.

FAQs

FAQs

Does the fibrous nature of your products help with soundproofing?

ROCKWOOL insulation’s high-density nature acts to lower the intensity of noise, with its structure helping to enhance sound attenuation through the wall.

How well does ROCKWOOL sound proof?

ROCKWOOL products are excellent at noise reduction and sound absorption. This makes them ideal for workplaces and apartment blocks in busy urban environments, as well as homes located near to airports.

What are the benefits of acoustic wall insulation?

Protection from unwanted noise can have a positive effect on our physiology, learning capacity and social behaviour. In offices, reduced noise pollution can improve productivity. At home, sleep and general comfort can benefit too.
