What is the difference between the RWA45, the RW3 and the RW5?
All three Rockwool products are made of the same material, with the difference being how tightly the fibres are compacted and how dense they are. The RWA45 has a density of 45kg m3, RW3 60kg m3 and RW5 100kg m3. Generally for domestic use the RWA45 is recommended, with the more dense slabs for industrial or particularly noisy areas.
