Universally recognised throughout the world of soundproofing, commonly used as part of an acoustic system, or combined with additional acoustic materials such as our MuteClip®.

Knauf Acoustic Mineral Wool (RS60) (60kg per m3) is high-density acoustic mineral wool that is used to treat the open spaces, or cavities, between flooring joists, stud-frame walls and battened ceilings. Acoustic Mineral Wool works by lessening sound energy by turning it into heat, helping to decrease the remaining noise 'bouncing' around inside the cavity and amplifying. As a standalone product, it is only effective against very light background noise issues. We recommend Knauf Acoustic Mineral Wool to be used as part of a system when a cavity is created or existing. Acoustic Mineral Wool will also help to prevent Flanking Transmission adjacent cavities. Any soundproofing system fitted without this material will not achieve its complete acoustic performance and may fall short of expectations or essential acoustic regulations.
Acoustic Mineral Wool has a greater density than thermal wool, and this is evident in their slab appearance. The reduction as an acoustic insulation material comes as an absorptive rating NRC (Noise Reduction Coefficient) which differs for each thickness. This means that it is an absorptive material as opposed to a dense soundproofing product.

The world of soundproofing and general construction presents an uncertain journey for those arriving fresh to the subject, there maybe terminology or use of acoustic testing figures that could appear confusing, and even if you are at a professional level, it is good to brush up to make sure you are making the right choice. We want to help you come to the right decision, so whether this is through the use of our guides or talking to a member of our team - we are here to help!
A combination of the following will always result in a much improved acoustic performance.
Acoustic Mineral Wool is your best friend when you are up against soundproofing that has cavities across walls, floors and ceiling. It has a low cost per square meter, incredibly easy to install and effective against a range of frequencies. The Knauf brand is well established and is used across commercial projects internationally, whether it is residential, commercial or industrial - using Knauf Acoustic Mineral Wool 60kg will help secure brilliant performance for your soundproofing project.
To create a soundproofing system that can reduce an extensive range of sounds and noises, you will need to combine all of the properties above. By separating the mass from the structure and suspending it away, you are breaking contact with the construction and creating an air gap, in this air gap must feature Acoustic Mineral Wool, as it is essential for reducing Flanking Transmission, and reducing any sound making it into the cavity. Low-frequency noises and vibration are not just created in areas with amplified music or machinery, but can arise from televisions attached to the wall, or the low-tone of a male voice and even closing a door. These noises typically travel greater distances than you'd think.
We recognise the subjective nature of sound and how we react to each one, and that is why we offer so many variances in our systems. We understand that it is not always possible to incorporate significant loss with a stud frame, so we provide different variances to suit what performance you need, your budget and available depth.

60kg is the density of the product when measured in cubic meters and not the weight of a single slab or bale of acoustic mineral wool - it is a reasonably lightweight sound insulation product that is easy to cut and easy to lay, use gloves and eye protection and keep the area ventilated during and after installation.
100mm is the thickest slab of acoustic mineral wool available and is best used as stud wall insulation, between flooring joists or flooring frameworks with our MuteCradle options to prevent cavities from resonating, leaving them untreated will lead to any remaining sound passing through into these areas. You will also want to avoid using a thicker size than the air gap provided and aim to have at least a 10mm air gap on either side. Using a 100mm thickness in a 50mm cavity, for example, will lead to compression of the acoustic mineral wool and a direct path of sound to travel through which will result in degrading the acoustic performance.
You will want to install acoustic mineral wool in timber and metal frameworks, in our suspended ceiling or wall systems such as in our MuteClip System and flooring cavities between joists or with our MuteCradle options it can be used to treat all these cavities to reduce sound from bouncing around inside them and resonating. But, it is essential to note that this is a lightweight, fibrous material and this means that sound will pass through it - so it is not effective in reducing airborne nor impact noise issues as a standalone solution.
Acoustic Mineral Wool is fibrous and will release fibres into the room when exposed, and it should only be placed in cavities and generally is not recommended to use as an exposed sound absorption material for this reason.
We offer a comprehensive range of sound absorption range that can are available in an almost unlimited range of possibilities across a broad range of colours.
As a fibrous material, it can lead to slight irritation of the skin, those with sensitive skin may find a slight redness appear while handling it - the use of gloves and protective eyewear is recommended.
