Knauf Earthwool Acoustic Insulation Roll | 75mm

Acoustic Insulation, as the name suggests, is used to balance the acoustics of a room and is designed to deflect, absorb and dissipate noise to a manageable level. The Knauf Earthwool Acoustic Insulation comes in roll format, making it strong, resilient and much more flexible compared to insulation slabs. The roll format is just as durable and stable as the slab format, as the roll will not slump under its own weight when suspended vertically in to walls. There are also friction fits between the stud centres to ensure continuity of the absorbent layer, leaving no air gaps. This insulation roll is perfect to absorb sound in multiple settings, including homes, offices, music studios and attics. They can also be used underneath flooring, to provide a luxurious and unique finish.
This product meets all the health and safety requirements for installation, including Euroclass A1 to BS EN 13501-1 Fire Classification.

The difference between acoustic and thermal insulation is that thermal helps to keep your building warm. It also stops heat transfer whereas acoustic helps stop sound vibrations.

You can install acoustic insulation in the wall cavity, in floors and in roofs.

Using acoustic insulation can effectively absorb sound.

Acoustic insulation is made of mineral wool insulation with non-directional fibre orientation.

Acoustic insulation adds mass to help stop sound vibration through a structure.

Using an acoustic insulator can be effective in absorbing sound vibration when used with other soundproofing methods.
