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. As an open-fibrous material, it helps to reduce sound energy by turning it into heat, helping to reduce cavity resonance. 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 open cavities. Any acoustic system fitted without this material will not achieve its full 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 may be the 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 with cavities across walls, floors and ceiling. It is 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 not its surface density, but the density of the product which is measured in cubic meters, it is a fairly lightweight sound insulation material which is easy to cut and fit.
The 25mm thickness is the thinnest dense slab available and is used to help insulate small cavities, for using with 'boxing in' pipes with our MuteWrap and used with our MuteClip® direct to brick or block wall constructions where a small air gap is created. Do not compress Acoustic Mineral Wool between the sound source and soundproofed surface as this creates a direct path for sound to travel through, this will degrade the performance of the soundproofing system.
You will want to install Acoustic Mineral Wool in conjunction with dense soundproofing materials, and it is essential to note that as a lightweight, fibrous material, the sound will pass through it and that its prime function is to reduce noise reverberating around an empty cavity and not as a standalone to reduce noise transfer between rooms.
Acoustic Mineral Wool is a fibrous material, which means that fibres are released into the air when exposed and why it is usually used in a cavity or covered. It is not recommended to use as exposed panelling.
We offer a vast range of sound absorption materials we tailor to your creative imagination with a variety of colours, as well as stock items in a range of designs and colours.
We have found that a bread knife usually makes for an excellent cutting tool if this is unavailable - a large pair of scissors will also work well.
There are no dangerous properties found in Acoustic Mineral Wool, but as it is fibrous it can give a slight irritation to the skin. Those with sensitive skin may experience itching, so we recommend the use of gloves and protective eye-wear. This will be the case for all mineral wool insulation.
