Internal Walls must be well insulated to prevent the passage of sound between them. To achieve this, acoustic insulation is often installed in stud partitions between the layers of plasterboard.
This acoustic insulation comes in two forms; rolls and slabs. Knauf Acoustic Roll is the most popular product in roll form, whereas Rockwool RWA45 Acoustic Slab is the most common of the slab products. With a density of 45kg, the Rockwool RWA45 is the most effective for enhancing the acoustic properties of an internal wall.
