Rockwool RWA45 Insulation Storage & Handling

RWA45 is a durable insulation solution which is trouble-free when it comes to cutting so you can get the best fit possible in all situations.  The slabs have a soft, fibrous texture, very similar to a loaf of bread. Because of this, a serrated blade is all you need to slice through it.
When it comes to storage, we advise that you store the slabs inside; keeping them nice and dry.

Rockwool RWA45 75mm Acoustic Performance

Rockwool thermal and acoustic insulation slab is best known for its excellent acoustic performance. 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 stone wool products 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.
Its higher density and non-directional fibre structure trap sound waves and deaden sound vibrations like no other insulation on the market. The structure of the fibres in RWA45 slabs grants them their incredible sound-absorbing performance, with characteristically high coefficients over a wide frequency range.
