Knauf Acoustic Insulation Roll (8 Products)

Nip noise in the bud with Knauf Acoustic Insulation Roll. Due to their sound-preventative nature, the rolls are primarily designed for use in internal wall and floor applications - applications of which are prime culprits of sound travel. Another downside of internal partitions is, of course, the increased likelihood of fire spread - Knauf Acoustic Roll also serves as a preventative measure, in this case, thanks to its Euroclass A1 reaction to fire classification.

Knauf Acoustic Insulation Roll


Knauf Acoustic Insulation Roll is a lightweight and flexible glass mineral wool roll compatible with all major brands of plasterboard. 

Boasting a non-hygroscopic composition, the rolls do not sustain vermin, nor do they encourage the growth of fungi, mould or bacteria - ensuring ultimate longevity for the lifetime of your build. 

Another welcome benefit of Knauf Acoustic Roll is its friction-fitting design - the rolls can be fitted between timber battens/studs in separating floors and walls, as well as between timber/metal studs in plasterboard partitions. 


Knauf Acoustic Insulation Rolls have been put through multiple rigorous tests to assure their compliance with sound-related building regulations in the following applications: 

  • Separating floors and floors 

  • Internal walls and floors

  • Timber and metal stud partitions

Frequently Asked Knauf Acoustic Roll Questions

What Endows Acoustic Insulation with its Sound Absorption Properties? 


When you break it down, sound insulation is all about adding mass; and layers upon layers of dense materials. When sound waves travel through the air, they pass from material to material in vibrations. The more mass that a sound wave has to travel through, the fewer vibrations that will reach the other side of the material. A dense insulation roll or slab can dampen sound waves and cause them to dissipate, so you can no longer hear noises from other rooms, or outside.

Knauf Insulation Acoustic Roll has a manufactured density in excess of 10kg/m³ meeting the requirements outlined within relevant sound-related building regulations. 

What Exactly Is ECOSE Technology? 


ECOSE technology is a breakthrough, formaldehyde-free binder technology, based on highly sustainable and renewable materials as opposed to typically used petro-based chemicals. Not only does this industry innovation reduce embodied energy but it also achieves new heights in environmental sustainability.

What Is The Difference Between Airborne Noise & Impact Noise? 


Airborne noise is essentially sounds which are transmitted between rooms via flanking elements. To put it simply, airborne noise is noise which travels through the air. 

Impact noise, on the other hand, is noise which is transmitted throughout a property when an object meets another object. A common example is footsteps on a wooden floor. You can easily combat impact sound by installing either a thick carpet or padding layer throughout your property.
