Rockwool RW5 100mm Acoustic Performance

These slabs have a density of 100kg/m3 per slab. The denser the material, the more layers that sound vibrations have to travel through. Rock is a naturally poor conductor of sound. RW5 is the perfect choice for people who want to insulate their homes against unwanted noise. 

Rockwool respectfully thrashes competitor brands with its prevention of noise transmission from room to room, making it ideal for installation in internal and separating walls. 

Rockwool RW slabs work in two distinct ways to dampen sound, either by impeding the transmission of sound through an element of the structure or by absorption of sound at the surface.
